Description

Adenovirus and application thereof with expressing genes in reverse

The present invention relates to adenovirus, encode their nucleic acid and application thereof, particularly be used for the treatment of the application of the medicine of tumour in preparation.

Currently utilize many treatment principles in the tumour in treatment.Except using surgical operation, chemotherapy and radiotherapy are dominant.Yet all these technology are all with sizable side effect.Duplicate the new platform that the optionally application of oncolytic virus provides the treatment tumour.Correspondingly, cause in the optionally tumour of viral agent and duplicate, cause virus replication, be subjected to the diffusion of the cracking of transfected tumor cell and virus to adjacent tumor cells.Because the virus replication ability is limited to tumour cell, healthy tissues avoids virus replication and therefore avoids virolysis.

At present, several viral systems are carried out purpose and be the clinical trial of tumour cracked.An example of this adenovirus is dl1520 (Onyx-015), and it successfully has been used for the I phase and the II phase clinical (Khuri, Nature Medicine 6 such as F., 879-885,2000).Onyx-015 is a kind of adenovirus that lacks the E1B-55kDa gene fully that has.The proteic disappearance fully of the E1B-55kDa of adenovirus is based on a discovery, and the adenovirus carrier that promptly has a p53 disappearance may cause duplicating and therefore cracking (Kirn, the D. etc. of cell, Proc.Am.Soc.Clin.Oncol.17,391a, 1998), wherein normal cell preserves from.More specifically, the E1B-55kDa gene product participates in the inhibition of p53, and the transhipment of virus mRNA and host cell proteins synthetic cut off.The inhibition of p53 is by taking place by the proteic mixture of E1B-55kDa of p53 and adenovirus coding and/or by the forming of mixture of E1B-55kDa and E4orf6.By the p53 of TP53 coding is the starting point (Zambetti, G.P. etc., FASEB J.7,855-865,1993) of mixture regulation mechanism, and it suppresses the cellular replication of viral (as adenovirus) especially effectively.Gene TP53 lacks in about 50% everyone tumour or suddenlys change, and causes the apoptotic shortage of expectation that caused by chemotherapy or radiotherapy, causes common unsuccessful oncotherapy.

Another principle of cracking tumour (tumorlytic) adenovirus is based on a discovery, if promptly E1A albumen exists with specific disappearance form or comprises one or more sudden changes and do not influence the combination of Rb/E2F and/or p107/E2F and/or p130/E2F, this adenovirus not cell of inductive infection enters the S phase, and can duplicate in not containing the proteic tumour cell of functional Rb.In addition, E1A albumen can comprise one or more sudden changes at the N-terminal deletion with on the amino acid region of the proteic 1-76 of E1A respectively, so that suppress combining and so being provided at copy choice in the tumour cell of E1A and p300.These methods are described in the mode that exemplifies in European patent EP 0 931 830.These viral examples are Ad Δs 24, dl922-947, E1Ad/01/07 and CB016 (Howe, J.A. etc., Molecular Therapy 2,485-495,2000; Fueyo, J. etc., Oncogene 19,2-12,2000; Heise, C. etc., Nature Medicine 6,11341139,2001; Balague, C. etc., J.Virol.75,7602-7611,2001).Therefore these adenovirus systems that become known for oncolysis in the prior art comprise disappearances different in the E1A albumen, wherein under following hypothesis, made these disappearances: functional Rb albumen and can block respectively in the effective body by the mixture that the Rb albumen and the E2F of non-activity forms and to duplicate, so that adenovirus only carries out duplicating in the body in Rb-feminine gender/mutant cell.These adenovirus systems according to prior art are based on E1A, so that by early stage E2 promotor (English is E2 early promoter) and free E2F (Dyson, N.Genes ﹠amp; Development, 12,2245-2262,1998) duplicate in the control volume.

Can duplicate with extra high level behind cells infected with the adenovirus that this mode designs, described cell is expressed YB-1 in nuclear, preferably express YB-1 in being independent of the nuclear of cell cycle, and perhaps it comprises the YB-1 that regulates, preferably in tenuigenin.Hope is not limited thereto, the present inventor supposes below, independent a kind of in the mixture that E1B albumen and/or E4 albumen are formed and these two kinds of albumen can transport the YB-1 that goes to regulate respectively in the nucleus, perhaps can start duplicating of adenovirus there under prior to the E1B albumen of E1A protein expression and/or the proteic influence of E4.In case in nucleus or with the activatory form, be present in the there, as described here, more specifically use the E2-late promoter, YB-1 duplicates effectively.Therefore, E1B albumen and/or E4 early express on the proteic time and have avoided observed cascade in the wild-type with the proteic initial expression of E1A.In a preferred embodiment, E1A albumen is special no longer trans-activation or only E1B albumen and/or E4 albumen trans-activation can be arrived the very E1A albumen of limited extent.Preferably, this trans-activation neither sufficient to guarantee effectively duplicates, and also is not enough to guarantee duplicating in cell, does not contain YB-1 in the nuclear of described cell.Preferably, trans-activation does not occur in such cell, and it is independent of in the nuclear of cell cycle and does not contain YB-1, does not perhaps have the YB-1 that regulates.

And, the present invention is based on unexpected a discovery, be that adenovirus can be duplicated with special efficient manner, if it comprises the nucleic acid of at least a energy proteins encoded, wherein said albumen is selected from and comprises proteic group of E1B albumen, E4 albumen and E1A, at least a albumen wherein is under the control of promotor, and described promotor is different with the promotor of each protein expression of control in wild-type adenovirus.Duplicating like this is effective especially, and cause the tumour cracking usually,, particularly in being independent of the nuclear of cell cycle, contain YB-1 if this cell contains YB-1 in nuclear, if perhaps this cell contains the YB-1 that regulates, particularly in tenuigenin, contain the YB-1 that regulates.The content of describing about E1B albumen, E4 albumen and E1A albumen in the above also is applicable to this.In wild-type adenovirus, E1B albumen is by the control of E1B promotor, and E4 albumen is by the control of E4 promotor, and E1A albumen is controlled by the E1A promotor.By selecting and the different promotor of promotor of in wild-type adenovirus, controlling aforementioned protein expression, change the interaction of the modulability between aforementioned proteic expression and each adenoviral nucleic acid and the albumen thus.By selecting promotor, can go up different expression maps Time Created, wish not limitedly below, cause observed duplicating in the cell, mechanism wherein may be that to go up different expression about the time of adenovirus protein E1B, E4 and E1A in front described.Example by promotor (different) the described proteic specific design of control with each proteic expression promoter of control in wild-type adenovirus, can from following claim and embodiment part, obtain, wherein more specifically, viral XVirPSJL1 that mentions and XVirPSJL2 are wherein representational.Preferably, E1B albumen is E1B55kD albumen, and E4 albumen is E4orf6 albumen, and E1A albumen is E1A12S albumen.

Preferably control the group that the proteic promotor of E1B albumen and E4 is selected from the promotor that comprises tumour-specific, organ specific promotor, tissue-specific promotor, allogeneic promoter and adenovirus promoter, its condition is, when using adenovirus promoter, they are different with the E1B promotor of control E1B protein expression, and different with the E4 promotor of control E4 protein expression.Particularly preferably be, use E1A promotor control E1B albumen and/or E4 protein expression.The E1A promotor is documented in for example Boulanger P.A. and Blair, G.E.Biochem.J.1991, and 275, among the 281-299.In addition, can also use each and any other allogeneic promoter, promptly with the different promotor of promotor of each protein expression of control in wild-type adenovirus.Representational example is the CMV promotor, and other promotor is conspicuous to those skilled in the art.

Be used to control the group that the proteic promotor of E1A can also be selected from the promotor that comprises tumour-specific, organ specific promotor, tissue-specific promotor, allogeneic promoter and adenovirus promoter, its condition is that adenovirus promoter is different with the E1A promotor.The present invention includes, one or more in the aforementioned albumen (being E1B albumen, E4 albumen or E1A albumen) are under the control of identical promoters, and however, preferably, particularly E1B albumen and E4 albumen are under the control of identical promoters.Particularly preferably be, the proteic expression of E1A maybe can be controlled by the promotor that YB-1 regulates by the promotor of YB-1-control.Such promotor is open relevantly with others of the present invention in this article.Particularly preferably, expression with adenovirus 2-late promoter control E1A promotor, because it at first can be regulated by YB-1, secondly also do not having only to show small in fact negligible transcribing under the situation of YB-1, thereby can guarantee very well to control expression of nucleic acids by the control of E2-late promoter.This has improved biological safety significantly, particularly when being used for field of medicaments.

And, the present inventor has been found that, adenovirus can be duplicated in cell particularly well, described cell contains YB-1 in nuclear, more specifically in being independent of the nuclear of cell cycle, contain YB-1, and/or contain the YB-1 that regulates, preferably in tenuigenin, contain the YB-1 that regulates, if directly or indirectly particularly in nucleus, provide YB-1 for duplicating, if perhaps providing of YB-1 is directly or indirectly to mediate by adenovirus protein, wherein said adenovirus protein is different with E1A.This aspect of the present invention is with disclosed aspect is different herein, the application that is the preferred II group of the adenovirus adenovirus of trans-activation E1A-modification can make these viruses duplicate in YB-1 nuclear-male tumour cell, particularly the YB-1 male is independent of the YB-1 nuclear-positive cells of cell cycle, and contain the YB-1 that regulates, those cells that particularly in tenuigenin, contain YB-1, do not utilize the trans-activation feature of E1A albumen (particularly E1A13S albumen) here, promptly about I group adenovirus, but in a preferred embodiment, E1A13S albumen is inactivation on the function, thereby no longer can trans-activation E4orf6 and E1B55k, they directly or indirectly participate in the transhipment of YB-1 respectively and provide in nuclear.As a result, according to this aspect of the present invention, can not duplicate adenovirus effectively.In this scope, now the YB-1 that provides and carry out for adenoviral replication of the YB-1 in the nuclear the control that no longer is subjected to the proteic direct or indirect participation of E1A is provided, but the E1B albumen (particularly E1B55kD albumen) by not being subjected to E1A control and/or the expression of E4 albumen (particularly E4orf6 albumen) realize.

This embodiment of adenovirus can also be by a kind of realization the in the above-mentioned measure, for example by comparing with the proteic expression of E1A, in advance E1B albumen and/or proteic time of E4 go up and express, perhaps by in E1B albumen, E4 albumen and the E1A albumen one or more being placed and controlling under the control of the different promotor of each proteic expression promoter in wild-type adenovirus.

At last, the present inventor is from unexpected discovery, be that effective adenoviral replication can also take place particularly to contain in nuclear in the cell of YB-1, more specifically in being independent of the nuclear of cell cycle, contain in the cell of YB-1, perhaps containing the YB-1 that regulates, preferably in tenuigenin, containing in the cell of the YB-1 that regulates, if at least one in E1B albumen, E4 albumen and the E1A albumen, particularly their preferred form are to express in the expression cassette under promotor control.In one embodiment of the invention, provide 3 kinds of expression cassettes basically, each all contains a kind of described albumen separately.In an alternative embodiment, expression cassette can also contain two or more albumen E1B, E4 and E1A and their derivative and possible surrogate respectively, particularly under the situation of E1A12S.Describedly in the past comprise the content of the nucleic acid relevant with E1A, also be applicable to the various albumen of design and the promotor of use separately with albumen E1B, E4 about adenovirus.When using such expression cassette, preferably, completely or partially deleted the albumen in the genome of wild-type adenovirus and their nucleic acid of encoding, described albumen is corresponding to each albumen of expression cassette, guaranteeing that virus is stable, and preventing reorganization, is at least on bigger degree.

In principle, expression cassette can be cloned each zone and each site of adenovirus into respectively, wherein preferably with one or several expression cassette respectively or combination with one another ground be inserted into viral E1 district, E3 district and/or E4 district.The nucleic acid in E1, E3 and E4 district may be by completely, partly deletion, perhaps not deleted at all, yet according to the present invention preferably about adenovirus, the nucleic acid of coding E1A13S gene be inactivation or disappearance, so this virus can not provide any trans-activation E1A albumen.This disappearance degree of one or more area E 1, E3 and E4 depends on the expression cassette of use and the foreign gene or the transgenosis that randomly further import or contains their other expression cassette, promptly different genes with adenoviral gene, at least to a certain extent different, be that they are not that adjusting content by dominant adenoviral nucleic acid in wild-type adenovirus provides, neither provide by adenovirus nucleic acid sequence in the wild-type adenovirus in this site.The present invention includes, in the adenoviral gene group, partially or even wholly deleted the nucleic acid that in one or more coding E1B albumen, E4 albumen and/or the proteic expression cassette of E1A, contains.In one embodiment, for example in adenovirus XvirPSJL1 according to the present invention or 2, partly delete the adenoviral nucleic acid of coding E4orf6, but contained its complete nucleic acid of to encode in the expression cassette.Preferably, this also can realize at E1B55k (being also referred to as E155Kd) albumen and/or E1A12S albumen.The degree of disappearance will be selected in preferred embodiments, so that the maximum packing size reaches maximum packing size about 103% of wild-type adenovirus, although this boundary is a preferred boundary.The possible disappearance of making in the adenoviral gene group only limits in preferred embodiments, to guarantee producing particle infective and packing.On the basis of content disclosed herein and standard test, those skilled in the art can determine the levels of precision that lacks.

The YB-1 of cell should be meant that wherein this YB-1 exists in the cell by cell coding and preferred also by any YB-1 of cell expressing, particularly before each cell infection adenovirus, and preferred adenovirus as herein described of described adenovirus and/or helper virus.Yet the present invention also comprises, the YB-1 of cell be introduce cell or by only applying the YB-1 of outside measure (for example using virus, preferred adenovirus infection) by these cells produce.

Below do not wish fettered by this, the present inventor supposes that E2-early promoter (being early stage E2 promotor) is not to open by people's cell E2F transcription factor, described E2F transcription factor is relevant with duplicating of virus used according to the invention, and also the application according to the present invention with adenovirus of the present invention is relevant.Under such environment, the Rb state that begins to be independent of cell that duplicates, promptly use virus infection disclosed herein and preferred cracked tumour cell subsequently can comprise the Rb albumen of functional and non-activity.In addition, the duplicating of adenovirus of using adenovirus disclosed herein or using condition disclosed herein without any need for functional p53 albumen, but be not subjected to the negative impact of its existence yet.So, this technology instruction has deviated from the principle of using the adenovirus that can clear up tumour or energy cracking tumour, the type of described adenovirus is Ad Δ 24, dl922-947, E1Ad/01/07, CB016, or those adenovirus of for example in European patent EP 0 931 830, describing, introducing one or several disappearances under the following hypothesis in E1A albumen: intact functional Rb albumen can effectively duplicate in the baffle, and therefore duplicating of adenovirus only be provided in the body in Rb-feminine gender and Rb-mutant cell.These adenovirus systems of prior art are based on E1A, so that duplicate in the body by early stage E2 promotor (E2 early promoter) and " free E2F " control adenovirus.Yet, these known viruses of the prior art can be used for duplicating of cell according to the present invention, described cell contains YB-1 at the nuclear that is independent of the cell cycle, perhaps contains the YB-1 that regulates.

Can use the virus of in described European patent EP 0 931 830, describing, particularly adenovirus according to the present invention.More specifically, the virus of describing in described patent is replication defective, and can not express the virus of viral cancer protein, the Rb tumor suppressor gene product that this cancer protein can combined function.Adenovirus can be in particular any adenovirus that can not express viral E1A cancer protein, the tumor inhibitor gene product that this E1A cancer protein can combined function, Rb more specifically.Virus E1A cancer protein can show the inactivation sudden change, for example at the CR1 structural domain of the amino acid sites 30-85 of adenovirus Ad5 (being also referred to as Ad5 in this article), at the amino acid sites 120-130CR2 of nucleotide site 697-790 and/or Ad5 structural domain, nucleotide site 920-967, it relates to the proteic combination of p105Rb albumen, p130 and p107.But the present invention comprises that also adenovirus is the dl 312 of type 2 or the NT dl 1010 of type 5.

Prepare medicine about adenovirus according to the present invention, the particularly application of the medicine of preparation treatment neoplastic disease and other disease disclosed herein, the application of in cell, duplicating about the application and the adenovirus of the present invention of adenovirus of the present invention, described cell contains YB-1 at nuclear, preferably contain YB-1 at the nuclear that is independent of the cell cycle, perhaps contain the YB-1 that regulates, preferably in tenuigenin, duplicate and finally occur in such cell, it contains YB-1 at nuclear, preferably is independent of the cell cycle, in other words, they are YB-1 nuclear-male, perhaps occur in the cell that contains the YB-1 that regulates.It should be noted that especially so adenovirus is not duplicated or duplicated with significantly reduced level in following cell: do not contain YB-1 and only in tenuigenin, contain YB-1 in its nuclear, perhaps do not contain any YB-1 of regulating of going.Therefore, the success of these viruses is duplicated and need be had YB-1 in nuclear, preferably is independent of the cell cycle, perhaps exists to remove the YB-1 that regulates.As will be described below in more detail, this can apply measure by for example pair cell and realize, this measure can cause expression or the existence of YB-1, preferably is independent of the cell cycle, or removing the YB-1 that regulates in the nuclear, or goes the expression of the YB-1 that regulates.Various measures can for example be respectively that this adenovirus is also carried the genetic information of coding YB-1 and the YB-1 that particularly encodes expression except adenoviral gene by used according to the invention or experience coding and the expression of adenovirus YB-1 of the present invention.Other measure that causes YB-1 transhipment in the nucleus, induces or express be adopt stress, as apply cytostatic agent, irradiation, overheated etc. to cell and the organism that comprises this cell.In a preferred embodiment, irradiation can be any radiation, and it is for example employed in the treatment neoplastic disease.

Characterized in preferred embodiments used according to the invention, especially for tumour cracked adenovirus and according to adenovirus of the present invention, it is characterized in that, they do not duplicate in following cell: its be independent of do not contain in the nuclear of cell cycle YB-1 and thereby be YB-1 nuclear-feminine gender, perhaps do not contain any YB-1 of regulating of going.

Another feature of a part of adenovirus (they are different with adenovirus of the present invention) that will be used according to the invention is that they are coded in the viral oncogene that this is also referred to as oncogene protein, wherein oncogene protein is preferably E1A, and wherein oncogene protein can activate at least one influential virogene of lysis to the virus replication and/or the cell that is infected by the virus.Preferably, be such to the influence of duplicating, to compare with the situation of the oncogene protein disappearance of various viruses wherein, virus is duplicated better in the presence of oncogene protein.This process is also referred to as trans-activation in this article, when trans-activation is when mediating by E1A, is called the E1A trans-activation particularly.Following process preferably described in term " trans-activation ", be that various viral cancer proteins are different from other expression of gene of the own gene of the viral cancer protein gene of coding and/or transcribe influential one or more, promptly control its expression and/or translation, particularly activate.These virogenes are preferably E1B55kDa, E4orf6, E4orf3 and E3ADP, and aforementioned gene and gene product any combination separately.

Although the just optional feature of another of adenovirus used according to the invention and adenovirus of the present invention be respectively them to tumor inhibitor Rb in conjunction with feature, and in their encoded protein more concrete to tumor inhibitor Rb in conjunction with feature.In principle, the present invention includes adenovirus energy used according to the invention or can not combine with Rb.The application of any of two kinds of adenovirus alternative embodiment is independent of the Rb state that maybe will handle cell of processing.

In order to give the ability of E1A debond Rb, can carry out following deletion: the disappearance of the disappearance of CR1 zone (amino acid sites 30-85 among the Ad5) and CR2 zone (amino acid sites 120-139 among the AD5) to the E1A cancer protein.In the process of carrying out, the CR3 zone is retained, and can have the trans-activation function to other early stage virogene.

But in order to give E1A ability in conjunction with Rb, following disappearance to the E1A cancer protein is possible in principle: the disappearance of CR3 zone (amino acid sites 140-185); The disappearance of N-end (amino acid sites 1-29); The disappearance of amino acid sites 85-119; Disappearance with C-end (amino acid sites 186-289).Above-mentioned zone of listing does not influence combining of E2F and Rb.The trans-activation function is kept perfectly, and still compares with wild-type Ad5 to decrease.

The present invention also comprises, particularly about adenovirus of the present invention, E1A albumen, particularly E1A12S albumen are designed to like this, in one embodiment, it can be incorporated into Rb, in different embodiments, it not can be incorporated into Rb, wherein such E1A12S albumen is E1A albumen, the E1A12S albumen on the meaning of the present invention more specifically, however it is called the E1A12S of modification in the prior art sometimes.The proteic various designs of E1A12S more specifically about the aforementioned disappearance of E1A albumen (it also abbreviates E1A in this article as), are known to those skilled in the art.

Substantially known in the prior art and these adenovirus that do not demonstrate any trans-activation are commonly referred to be replication defect type.Yet the present inventor's contribution is, has been found that they still can suitably particularly duplicate under the cell background under the background.The existence of YB-1 in nuclear, the existence that be independent of cell cycle of preferred YB-1 in examining, or remove the YB-1 that regulates, can produce or provide this suitable cell background.The fragment or the fraction that comprise cell extract at the used term cell of and any others of the present invention or cell system, and in external, the body or the cell of original position.On this degree, term cell system or cell also comprise be present in cell culture, tissue culture, organ cultures or any body respectively and former bit organization or organ in cell, its be isolating, in groups or as the part of tissue, organ or organism, but also in preferred live body, exist like this.Organism is preferably any vertebra biology, more preferably Mammals.More preferably, organism is the people organism.Other preferred organism is according to all respects those disclosed of the present invention.

In addition, also the present invention comprises, based on technology instruction provided herein, in cell, produced new virus, this virus can show adenovirus as herein described and those replication described in the prior art, described cell is a YB-1 nuclear-male, preferably is independent of the YB-1 nuclear-male of cell cycle, or comprises the YB-1 that regulates.In other words, preferably especially from known adenovirus, can design other virus, it has the feature of using relevant this paper definition according to the present invention.

Related to the present invention, opposite with virus of the present invention, want the E1A cancer protein of the modification of various adenovirus used according to the invention to examine at YB-1-positive cells in or comprise the early stage virogene of trans-activation in the cell of the YB-1 that regulates, E1B55K for example, E4orf3, E4orf6, E3ADP.Preferably, viral genome is not had other changes, various adenovirus can be in addition on this degree corresponding to the adenovirus or derivatives thereof of wild-type.

Disclosed in this article coding or comprise the virus of the oncogene protein on the trans-activation meaning of the present invention, comprise for example adenovirus Ad Δ 24, dl922-947, E1Ad/01/07, CB106 and/or in the adenovirus described in the European patent EP 0 931 830, it separately can the trans-activation early gene, as E1B, E2, E3 and/or E4, and be comparable to wild-type adenovirus, particularly wild-type Ad5.In these cases, trans-activation is responsible in the proteic specific region of E1A.In the serotype of various adenovirus, in E1A albumen, there is the zone of 3 high conservatives.The CR1 zone of amino acid sites 41-80, the CR2 zone of amino acid sites 120-139 and the CR3 zone of amino acid sites 140-188.The trans-activation function is mainly based on the existence in CR3 zone in the E1A albumen.The aminoacid sequence of CR3 exists in unaltered mode in aforementioned adenovirus.This causes early gene E1B, E2, and the trans-activation of E3 and E4, it is independent of whether YB-1 is present in nuclear or the tenuigenin.

In contrast, in recombinant adenovirus dl520, the CR3 zone lacks.Therefore, dl520 expresses so-called E1A12S albumen, and it does not comprise the aminoacid sequence in CR3 zone.As a result, dl520 only can bring into play extremely weak trans-activation function, particularly in the E2 zone, does not therefore duplicate in the cell of YB-1 nuclear-feminine gender.In YB-1 nuclear-positive cells, YB-1 trans-activation E2 zone, and therefore allow effectively duplicating of dl520.For the system that resembles dl520 of purpose described herein and be derived from they system application based on this.Another important difference between two kinds of aforementioned adenovirus groups (for example δ 24 (this paper is also referred to as Ad Δ 24) and for example dl520) is, compare with the cell of YB-1 nuclear-feminine gender or the cell that do not contain the YB-1 that regulates, early gene E1B, E3 and E4 are independent of the cell of cell cycle or contain in the cell of the YB-1 that regulates by trans-activation more fully at YB-1 nuclear-male.In contrast, in δ 24, there is not or only has fine difference.Yet, compare with wild-type adenovirus, dl520 and more specifically the proteic transactivation of E1A12S significantly reduce.Yet this trans-activation is enough to provide effectively duplicating in the YB-1 nuclear-positive cells, also shown in embodiment 10.In the proteic design of particularly described in this respect E1A as herein described, design with their nucleic acid of coding, so that comparing with wild-type oncogene protein E1A, E1A albumen has one or several disappearances and/or sudden change, comprise and preferred especially as with dl520 or Ad Δ 24, dl922-947, E1Ad/01/07, CB106 and/or proteic those designs of described E1A of being correlated with in adenovirus described in the European patent EP 0 931 830, it is the particularly embodiment of adenovirus of virus, it duplicates and is controlled, and preferably significantly controls by activating the E2-late promoter.Preferably, disappearance is the group that is selected from the disappearance of the disappearance of the disappearance that comprises the CR3 zone and N-end and C-end.Based on disclosure provided herein, those skilled in the art can produce proteic other of E1A and allow the embodiment of this adenoviral replication form.The proteic embodiment of foregoing E1A is also can be according to the embodiment of adenovirus use of the present invention, and described adenovirus is also referred to as adenovirus of the present invention or I group adenovirus in this article.

Previous embodiments is considered in the aspect that relates to vehicle group, and both the various elements of described nucleic acid not necessarily only were included in the carrier.Therefore, vehicle group is made up of at least two carriers.In addition, carry out any argumentation about carrier and also be applicable to carrier and vehicle group respectively.

The feature of I group adenovirus and/or II group adenopathy is various nucleic acid disclosed herein and gene product respectively, and can comprise well known by persons skilled in the art in addition and be wild-type adenovirus inherent all that element (Shenk, T.:Adenoviridae:The virus and their replication.FieldsVirology, the 3rd volume, editor .Fields, B.N., Knipe, D.M., Howley, P.M. etc., Lippincott-Raven Publishers, Philadelphia, 1996, the 67 chapters).

In order to explain rather than limit the present invention, below duplicating of adenovirus will be discussed simply.

Duplicating of adenovirus is very complicated process, normally based on human transcription factor E2F.During virus infection, at first express " early gene " E1, E2, E3 and E4." late gene " group is responsible for the structural protein of synthetic virus.For the activation of early gene and late gene, play crucial effect by the E1 zone that encode different E1A and proteic two the transcriptional units E1A of E1B and E1B form, because they induce E2, E3 and E4 gene transcription (Nevins, J.R., Cell 26,213-220,1981).In addition, the DNA that E1A albumen can start in the resting cell is synthetic, and therefore impels them to enter the S phase (referring to Boulanger and Blair, 1991).In addition, the tumor inhibitor of they and Rb class interact (Nature 334 for Whyte, P. etc., 124-127,1988).In this case, discharge cell transcription factor E2F.The E2F factor can be subsequently in conjunction with the corresponding promoter region (particularly adenovirus E2 early promoter) of cytogene and virogene, and cause and transcribe and duplicating thus (Science 258 for Nevins, J.R., 424-429,1992).The activity of pRb and E2F is regulated by phosphorylation.The low phosphorylation form of pRb mainly is present in G1 and M phase.On the contrary, the super phosphorylation form of pRb is present in S and G2 phase.By the phosphorylation of pRb, from the complex body that the pRb by E2F and low phosphorylation forms, discharge E2F.E2F is from causing the dependent gene transcription of E2F by the release the complex body of the pRb of E2F and low phosphorylation.Only in conjunction with the pRb of low phosphorylation form, wherein E1A takes place by the proteic CR2 of E1A zone with combining of pRb is most of E1A albumen.In addition, it also combines with the CR1 zone, although avidity lower (Ben-Israel and Kleiberger, Frontiers in Bioscience, 7,1369-1395,2002; Helt and Galloway, Carcinogenesis, 24,159-169,2003).

The initiation of duplicating and finish the gene product that needs the E2 zone especially is because three key proteins of they codings.Proteic the transcribing of E2 controlled by two promotors, " the early stage E2F-dependent form of E2-" promotor, it is also referred to as E2-early promoter or early stage E2 promotor in this article, " E2-late period " promotor (Swaminathan and Thimmapaya, The Molecular Repertoire ofAdenoviruses III:Current Topics in Microbiology and Immunology, volume 199,177-194, Springer Verlag 1995).In addition, the product in E4 zone plays an important role to the activity of E2F and the stability of p53 with E1A and E1B-55kDa albumen.For example, by by the E4orf6/7 of E4 regional code and the heterodimer direct interaction of forming by E2F and DP1 trans-activation E2 promotor (Swaminathan and Thimmapaya, JBC 258,736-746,1996) more.In addition, p53 makes the complex body inactivation of being made up of E1B-55kDa and E4orf6 (Oncogene 16 for Steegenga, W.T. etc., 349-357,1998), so that successfully finish the infectious cycle of cracking performance.In addition, E1B-55kDa albumen has another critical function, and promptly when with the E4orf6 protein-interacting, it promotes viral RNA output from nuclear, and wherein the RNA of cell remains in the nuclear (Bridge and Ketner, Virology 174,345-353,1990).Another important discovery is that the protein complexes of being made up of E1B-55kDa/E4orf6 is positioned so-called " viral inclusion body ".Infer that these structures are the sites (Ornelles and Shenk, J.Virology 65,424-429,1991) of duplicating and transcribing.

For duplicate, particularly another important area for the release of adenovirus is the E3 zone.The E3 zone more specifically comprises the genetic information of multiple relative small protein, and this albumen is not that the adenovirus Infection in Vitro cycle (promptly in cell cultures) is necessary.Yet the survival of their virus during for acute in the body and/or latent infection plays an important role, because they especially have immunomodulatory and apoptosis function (Marshall S.Horwitz, Virololgie, 279,1-8,2001; Russell, above).Can confirm that the albumen with about 11.6kDa size can inducing cell death.Because its function, this albumen is called ADP-english term adenovirus death protein-(Tollefson, J.Virology, 70,2296-2306,1996).This albumen mainly forms in the late period of infectious cycle.And proteic overexpression causes the better cracking (Doronin etc., J.Virology, 74,6147-6155,2000) of cells infected.

And, the virus of the known disappearance of the present inventor E1A, promptly do not express any 12S E1A albumen particularly and do not express proteic those viruses of any 13S E1A yet, they can duplicate (Nevins J.R. very efficiently under higher MOI, Cell 26,213-220,1981), yet it can not be realized in clinical application.This phenomenon is called " class E1A activity " in the literature.Also known from 5 albumen of E1A coding, two albumen, i.e. 12S and 13S albumen, (Cell 26 for Nevins, J.R., 213-220,1981 to control and induce the expression of other adenoviral gene respectively; Boulanger, P. and Blair, E.; Biochem.J.275,281-299,1991).This has confirmed that the proteic CR3 of 13S zone shows trans-activation function (Wong HK and Ziff EB., J Virol., 68,4910-20,1994) particularly.Yet, in the proteic CR1 of 13S and/or CR2 zone and/or the adenovirus of CR3 zone with particular hole be replication defect type basically, still trans-activation virogene and promotor in other clone, E2 zone (Wong HK, Ziff EB., J Virol.68 particularly, 4910-20,1994; Mymryk, J.S. and Bayley, S.T., Virus Research 33,89-97,1994).

Use the wild-type adenovirus cells infected, typically after the tumour cell, by E1A, E1B-55K and E4orf6 YB-1 is imported in the nuclear, be positioned viral inclusion body altogether with E1B-55K in nuclear, it allows, and ground effectively duplicates in nucleus in virosome other places and the body.Had been found that before that E4orf6 also can be in conjunction with E1B-55K (Weigel, S. and Dobbelstein, M.J.Virology, 74,764-772,2000; Keith N.Leppard, Seminars in Virology, 8,301-307,1998), and therefore mediate the E1B-55K transhipment respectively and be assigned in the nuclear, it guarantees best virus production and adenoviral replication.Pass through E1A respectively, the synergy of E1B-55K and YB-1, by the complex body of forming by E1B-55K/E4orf6 and YB-1, YB-1 and E1B-55K are in the common location of so-called viral inclusion body in nuclear, according to effectively duplicating of virus of the present invention is possible, therefore virus described herein is used for duplicating at cell, described cell is a YB-1 nuclear-male, the cell that preferably in being independent of the nuclear of cell cycle, contains YB-1, and/or contain or show the cell that removes the YB-1 that regulates, and/or preparation medicine, be used for the treatment of disease, wherein relate to YB-1 nuclear-positive cells, preferably in being independent of the nuclear of cell cycle, contain the cell of YB-1, and/or contain or show the cell that removes the YB-1 that regulates.Therefore, it is possible being replicated in this cell background, causes the cracking of cell, the release of virus and the infection and the cracking of flanking cell, and therefore in the situation of difference infected tumor's cell and tumour, oncolysis promptly takes place the final cracking of tumour.

YB-1 belongs to the classification of the high conservative factor, and it is in conjunction with reverse CAAT sequence, and it is called the Y-box.They can with the mode of regulating transcribe and translation skill on work (Wolffe, A.P.Trends in Cell Biology 8,318-323,1998).In growth and the activation of gene participating in apoptosis and inhibition, found the dependent adjusting approach of increasing Y-box (Swamynathan, S.K. etc., FASEB J.12,515-522,1998).For example, YB-1 is direct and p53 interacts, and (Oncogene 19,6194-6202 for Okamoto, T. etc., 2000), (Gene 252,1-13 for Lasham, A. etc. in Fas genetic expression, 2000), in genetic expression (Stein, U. etc., JBC276,28562-69,2001 of MDR and MRP; Bargou, R.C. etc., Nature Medicine 3,447-450,1997) and the activation of topoisomerase and metalloprotease (Mertens.P.R. etc., JBC 272,22905-22912,1997; Shibao, K. etc., Int.J.Cancer 83,732-737,1999) in play the essence effect.In addition, YB-1 also participates in regulating mRNA stability (Chen, C-Y. etc., Genes ﹠amp; Development 14,1236-1248,2000) and repair process (Ohga, T. etc., Cancer Res.56,4224-4228,1996; Izumi H. etc., Nucleic Acid Research 2001,29,1200-1207; Ise T. etc., Cancer Res., 1999,59,342-346).

By being present in the YB-1 in the nuclear that is independent of the cell cycle, or by transferring to the YB-1 that going in the tenuigenin regulated that is present in the nuclear by I group adenovirus and/or II group adenovirus, YB-1 locatees in the nuclear of tumour cell, cause in not expressing and use any 12S E1A albumen or any 13S E1A protein process, being independent of the virus replication (Holm of E1A, P.S. wait JBC 277,10427-10434,2002), and in the situation of protein Y B-1 overexpression, cause multi-medicine resistance.In addition, known adenovirus protein for example E4orf6 and E1B-55K has active effect (Goodrum, F.D. and Ornelles, D.A to virus replication, J.Virology 73,7474-7488,1999), wherein function E1A albumen is responsible for activating other virogene product (as E4orf6, E3ADP and E1B-55K) (Nevins J.R., Cell 26,213-220,1981).Yet this adenovirus for the known E1A-feminine gender of prior art does not take place, and does not have 13S E1A albumen in this adenovirus.YB-1 allows duplicating with particle of the negative virus of this E1A-to form respectively in the position of appraising and deciding that nuclear contains in the cell of multi-medicine resistance of YB-1.Yet in this case, Ad5 compares with wild-type, and virus replication and granuloplastic efficient reduce several times.In contrast to this, the combination of YB-1 allows the extremely effectively virus replication and the particle of YB-1 mediation to form, therefore and provide oncolysis, wherein YB-1 is Already in the nuclear of tumour cell, it may be from the YB-1 that is positioned at the nuclear that is independent of the cell cycle, perhaps wherein being present in the YB-1 that going in the tenuigenin regulate is transferred in the nuclear by I group adenovirus and/or II group adenovirus, perhaps introduce nucleus by external factor (for example dosed cells growth inhibitor or irradiation or overheated), promptly induce and be present in the nuclear, particularly be independent of the cell cycle, perhaps as transgenosis by the carrier system, preferred adenovirus system imports, and this adenovirus system can start adenoviral gene but not show virus replication.This also is applicable to according to adenovirus of the present invention, the I group adenovirus that promptly can duplicate effectively because of their specific design, and result of use, be E1B albumen, preferred E1B55K albumen and/or E4 albumen, preferably E4orf6 albumen provides YB-1, the preferably effective mobilization in nuclear.According to all respects of the present invention, the suitable cytostatic agent that can use with adenovirus disclosed herein is for example to belong to those of following group: anthracycline, as daunomycin and Dx; Alkylating agent is as endoxan; Alkaloids is as Etoposide; The vinca-alkaloid class is as vincristine(VCR) and vinealeucoblastine(VLB); Antimetabolite such as 5 FU 5 fluorouracil and methotrexate (methrothrexat); Platinum derivatives, for example cis-platinum; Topoisomerase enzyme inhibitor, as camphothecine, CPT-11; Taxanes, for example taxol (taxole), taxol (paclitaxel); Histone-deacetylase inhibitors, FR901228 for example, MS-27-275, trichostatine A; The MDR adjusting control agent, MS-209 for example, VX-710, and geldanamycin derivant, for example 17-AAG.Adenovirus disclosed herein, particularly recombinant adenovirus, only can examine at YB-1-positive cells in and containing, preferably in tenuigenin, containing in the cell of the YB-1 that regulates and duplicating, compare with the corresponding trans-activation ability of wild-type adenovirus, particularly wild-type Ad5, they are at trans-activation virogene E1B-55K, E4orf6, the ability aspect of E4orf3 and E3ADP is limited.The present inventor is surprised to find that now, and these limited trans-activation abilities can be by expressing corresponding gene, particularly E1B-55K and E4orf6 and overcoming in conjunction with the position of appraising and deciding of YB-1.Shown in this paper embodiment, the virus replication under this condition forms with particle and increases to respectively and can form the level that activity is compared with particle with the replication activity of wild-type adenovirus.

On the other hand, the present invention relates to screen patient's method, this patient can use a kind of adenovirus treatment of modification, it is for example Ad Δ 24 of adenovirus used according to the invention, dl922-947, E1Ad/01/07, the virus of describing in CB016 or the European patent EP 0 931 830, and/or I group adenovirus and/or II group adenovirus, wherein said method comprises the following step:

-analyze tumor tissues sample and

-determine whether YB-1 is positioned in the nuclear that is independent of the cell cycle, and perhaps whether this cell contains the YB-1 that regulates.

Replace or, can detect the existence of above-mentioned mark except YB-1.

Contain YB-1, particularly be independent of the cell cycle at nuclear in tumor tissues or its part, or contain in the situation of the YB-1 that regulates, can adenovirus disclosed herein used according to the invention, particularly I group adenovirus and II group adenovirus.

In an embodiment of the method according to this invention, finish the analysis of tumor tissues by using reagent, this reagent is selected from the antibody that comprises at YB-1, at the fit of YB-1 with at the spiegelmer of YB-1 and at the group of the anti-caline (anticaline) of YB-1.In principle, can also prepare the reagent of identical type, and be respectively applied for mark separately.Antibody, particularly MONOCLONAL ANTIBODIES SPECIFIC FOR are well known by persons skilled in the art.The another kind of reagent of specific detection YB-1 or mark be with their target structure with high-affinity bonded peptide, the target structure in situation of the present invention is YB-1 or described mark.In order to produce such peptide, known in the prior art its method, for example phage-displaying.For this purpose, from the peptide storehouse, wherein single peptide has about 8-20 amino acid whose length, and the size in storehouse has 10 approximately ²-10 ¹⁸, preferred 10 ⁸-10 ¹⁵Plant different peptides.A kind of can be so-called anti-caline in conjunction with the target molecule of the special shape of polypeptide, and it is for example described in German patent application DE 197 42 706.

Be used for specifically in conjunction with YB-1 or respective markers disclosed herein, and detect therefore that to be independent of the YB-1 of cell cycle be so-called fit at endonuclear localized another kind of reagent, be D-nucleic acid, it is based on RNA or DNA, as strand or double-stranded the existence, and combine with target molecule specifically.Fit generation is for example described in European patent EP 0 533 838.Fit a kind of specific embodiments is so-called aptazyme, and it is for example at Piganeau, N. etc. (2000), and Angew.Chem.Int.Ed., 39, no.29 describes in the 4369-4373 page or leaf.They are fit specific embodiments, because they also comprise the ribozyme part except comprising fit part, after the target molecule in conjunction with fit part, ribozyme partly obtains catalytic activity and shears nucleic acid primer in combination or release, and this is accompanied by the generation of signal.

Another kind of the fit of form is so-called spiegelmer, i.e. the target molecule bind nucleic acid of being made up of L-nucleic acid.The method for preparing this spiegelmer is for example described in WO 98/08856.

Can or obtain the sample of tumor tissues by surgical operation by puncture.Whether YB-1 is positioned to be independent of assessment in the nuclear of cell cycle often by using microscopy and/or immunohistology analysis to carry out, typically uses antibody or any other aforementioned agents to finish.Known other method of those skilled in the art detects YB-1 existence and its location therein in nuclear and is independent of the cell cycle.For example, when scanning needle during, can easily detect the location of YB-1 to the painted tissue slice of YB-1.With having frequency become in nuclear the be independent of cell cycle localized indication of YB-1 in nuclear.Another possibility that detects the YB-1 in the nuclear is to dye and detect YB-1 whether be positioned to examine the stage interior and definite cell at YB-1 with being independent of the cell cycle.Yet the detection of this and YB-1 also can realize by using aforementioned reagent at YB-1.Carry out the detection of reagent by method known to those skilled in the art.Because described reagent points to other structure of other structure, particularly cell in the sample that YB-1 so debond will analyze specifically, by means of the appropriate flags of reagent and since they be attached to YB-1 specifically, can detect and analyze the location of described reagent, also have the location of YB-1.The method of labelled reagent is known to those skilled in the art.Contain in the cell for test sample and how much remove the YB-1 that regulates, can also use identical technology.Whether also showed expression owing to the YB-1 that goes to regulate compares with the YB-1 that does not go to regulate, YB-1 also can use with respect to the relative expression of reference sample, go to regulate in the cell of analyzing so that detect YB-1.

Now, utilize drawings and Examples to further specify the present invention, therefrom will obtain new feature, embodiment and advantage.With its relatively,

Embodiment 1: the type that the E1A that adenovirus used according to the invention can comprise modifies

Fig. 1 has shown the structure design of adenovirus carrier AdE1/E3-feminine gender (being the adenovirus of E1/E3-disappearance), wild-type adenovirus and adenovirus dl520.

Adenovirus AdE1/E3-feminine gender does not contain the zone of E1A or the functional E1B or the E3 of encoding function, in this experiment as the toxicity contrast.

Wild-type e1a gene coding is 5 albumen altogether, and it is that selection montage by E1ARNA produces.Wherein, produce 2 different albumen, i.e. 289 amino acid whose albumen and 243 amino acid whose albumen.Dl520 289 the amino acid whose albumen of not encoding because there is disappearance in it in the CR3 zone of e1a gene, cause lacking the gene product of 13S.Operable adenovirus dl520 is called 12S-E1A virus by those skilled in the art according to the present invention.Adenovirus dl347 well known in the prior art (Wong und Ziff, J.Virol., 68,4910-4920,1994) also be can be used according to the invention 12S-E1A virus.

In 289 amino acid whose albumen, exist in 3 conservative between various adenovirus subclass zones by 13S-E1A mRNA coding.These are called CR1, CR2 and CR3.Although CR1 and CR2 exist in two kinds of E1A albumen (E1A 12S and E1A 13S), promptly in 289 amino acid and 243 amino acid whose albumen, the CR3 zone exists only in one bigger in aforementioned two albumen.

The virogene particularly activation of E1B, E2, E3 and E4 needs the CR3 zone.Only contain only trans-activation virogene pianissimo of less (promptly 243 amino acid whose) proteic virus, and do not promote in nuclear, not contain duplicating of adenovirus in those cells of YB-1.Because YB-1 exists only in the nuclear of tumour cell and only can detect there, this carrier is fit to duplicating of inducing tumor-specific.

Because the disappearance of CR3 among the dl520, this adenovirus can not be transferred to cell YB-1 in the nuclear of cell, it is also referred to as displacement in this article, therefore not the position of in the cell of YB-1 nuclear-feminine gender, duplicating, therefore be can be used according to the invention virus, wherein said virus comprises according to trans-activation required for the present invention.

Embodiment 2: the mode of action of adenovirus depends on the Rb state of cell

Fig. 2 has shown that E1A is proteic relevant to the combination of p300, p107 and p105 the territory.P300 and p107 are that cell is conjugated protein.Retinoblastoma protein (pRb) is a kind of tumor suppressor protein, and it is in conjunction with mediating by CR1 and CR2.Research shows, pRb and p107/p300 be combined in regulate transcribe in effective cell transcription factor E2F.Wild-type E1A albumen can disturb combining of E2F and Rb.So the E2F that discharges can be in conjunction with the E2 early promoter, and induces duplicating of adenovirus thus.

From known in the state of the art, some disappearance in the E1A cancer protein may produce as those the recombinant adenoviral vector of mentioning below, and it can duplicate to advantage in the cell of Rb-feminine gender and can be used according to the invention.For example, adenovirus carrier dl922-947 comprises the disappearance (amino acid sites 122-129) in the CR2 zone, and support C B016 has disappearance (amino acid sites 122-129) in CR1 zone (amino acid sites 27-80) and CR2 zone.Carrier E1Adl01/07 contains disappearance (amino acid sites 111-123) in the CR2 zone.In addition, because other disappearance of locating at N-end (amino acid sites 4-25) in addition, does not combine with albumen p300.Adenovirus carrier Ad Δ 24 contains disappearance (amino acid sites 120-127) in the CR2 zone.The adenovirus carrier of describing in patent EP 0 931 830 contains disappearance in CR1 zone and CR2 zone.

The releasing mechanism of the E2F of the binding mechanism of E2F/RB and E1A mediation is fundamentally different than the mechanism that constitutes basis of the present invention.Being different from and supposing in the prior art, is not the release of E2F from Rb albumen, though Rb albumen do not say for virus replication be critical also be necessary, but human transcription factor YB-1 appraise and decide the position.This transcription factor exists only in the tenuigenin in the cycle in most cells in normal cell.After with adenovirus infection, it is induced in the nuclear or has existed in the nuclear in different cell systems in some cases, as different neoplastic diseases, it comprises such as but not limited to mammary cancer, ovarian cancer, prostate cancer, the osteosarcoma cancer, glioblastoma, melanoma, small cell lung cancer and colorectal cancer.
