Description

A kind of oncolytic adenovirus mutant with the anticancer mechanism of multiple specific
Technical field
The present invention relates to be applied to a kind of oncolytic adenovirus mutant of oncotherapy, belong to life science, biomedical sector with the anticancer mechanism of multiple specific.
Background technology
Malignant tumour is with cellular abnormality propagation and to shift be a big class disease of characteristics.Global New Development tumor cases in 2000 is about 1,000 ten thousand, and is dead 6,200,000, existing ill example 2,200 ten thousand.China's tumor invasion and mortality ratio are in rising trend always, the about 180-200 ten thousand of tumor invasion number in 2000, and dead 140-150 ten thousand, in the town dweller, tumour has accounted for the first place of the cause of the death.Yet along with The development in society and economy, the primary hazard factor of tumour is not effectively controlled.At present to the treatment of malignant tumour still based on operation, radiotherapy, the chemotherapy of routine, this conventional treatment is difficult to receive the curative effect of expection concerning most tumours.Particularly for chemotherapeutics, its therapeutic index is low, and toxic side effect is big.In recent years, molecular biology had had the development of advancing by leaps and bounds, and gene therapy becomes after radiotherapy, chemotherapy, operative treatment a part indispensable in the complex therapy day by day.According to the statistics in December, 2004, totally 1020 the gene therapy schemes in the whole world enters clinically, mainly concentrates on the U.S., secondly is Europe, and 63.4% is used for treatment for cancer.The gene therapy of cancer mainly is to transport antioncogene with replication-defective vector at present, the clinical progress that carries the p53 gene with replication-defective adenoviral is the rapidest, the whole world has at least 5 to enter the III clinical trial phase, wherein the recombinant adenovirus p53 injection liquid " Ad-p53 " of China becomes the gene therapy for cancer medicine of first listing in the world in listing in 2004.
Adenovirus is the most commonly encountered diseases poisonous carrier of present therapy of tumor, has been widely used in the human body gene treatment plan, has the following advantages: genome is clear fully, easy handling; The human cell that can infect is extensive, and the dissimilar human tissue cell of can transduceing efficiently comprises cell stationary phase; Virus titer is higher, and the recombinant virus output of high titre is arranged in cell culture; Genome is big, thereby can insert big fragment foreign gene; Enter and be not incorporated into the host cell gene group in the cell, thereby security is higher, non-carcinogenesis.The adenovirus carrier replication-defective adenovirals that lack the E1 district that adopt more, can grow in the engineering cell of expressing the E1 gene and go down to posterity, the present most of adenovirus vector genome that uses mostly is viral genome and the integrate foreign genes of removing part E1a, E1b and E3 and forms.Though replication-defective adenoviral has shown certain security in vivo and in vitro, yet this type of adenovirus carrier of the great majority of using in clinical trial so far remains in many shortcomings, as time of expression alien gene is short, immunogenicity is stronger, significant cytotoxicity etc. is arranged during high titre, so clinical efficacy is not good.At present, oncolytic adenovirus treatment tumor development is rapid, and this oncolytic adenovirus treatment does not generally cause serious toxic side effect, unlimited toxic agent amount.The oncolytic adenovirus project that makes fast progress both at home and abroad comprises a plurality of clinical preceding project of U.S. Geron company and Introgen company, the ONYX-015 project of U.S. ONYX company (adenovirus of E1B-55kDa disappearance); The H101 project of the three-dimensional company in domestic Shanghai (be similar to ONYX-015, it is clinical to have finished the III phase, and listing will go through for the end of the year 2005).More and more data proves that oncolytic adenovirus promises to be the anti-tumor medicine of a new generation.
The human entity tumour has the characteristic of infinite multiplication, and this just needs the cell telomere to keep chromosomal stability.Telomere is the structure of eukaryotic cell protection end of chromosome, and normal cell divides once, and telomere will be lost 50~200 Nucleotide, finally causes necrocytosis.When cell cancerated, Telomerase activated, and replenished because chromosomal stability is kept in losing of the telomere that cell fission caused, and made cell escape dead and be immortalized, and finally caused tumor cell proliferation out of control.Studies show that human tumor has very high telomerase activation more than 90%, and normal somatic cell and benign tumor tissue Telomerase Activity are negative.Therefore, carrying out therapy of tumor with Telomerase as target spot may have broad prospects.Secondly, Epidermal Growth Factor Receptor Family (EGFRs comprises EGFR, Her-2, Her-3, Her-4) is a class glycoprotein receptor, is positioned on the cytolemma, belong to the I type and stride film Tyrosylprotein kinase growth factor receptors, comprise the film outskirt, stride the film district, three parts of film inner region.When part with after the film outside part of acceptor combines, the tyrosine residues phosphorylation of part in the acceptor born of the same parents, form the tyrosine substrate binding site, EGFRs is activated, pass through a series of signal transduction path that nuclear factors such as Ras, Raf, MAPK participate in again, cell signal is gone in the nucleus the synthetic and cell propagation effect of mediated dna by cell surface.The generation of EGFRs overexpression and kinds of tumors, development and prognosis have substantial connection, but found to comprise the most tumors cell high expression level EGFRs of nonsmall-cell lung cancer, straight colorectal carcinoma, mammary cancer, kidney and prostate cancer etc., the tumour patient of EGFRs high expression level easily shifts, recurrence time is short, the recurrence rate height, survival time is short.Because the Tyrosylprotein kinase of EGFRs is the prerequisite of signal transduction, thereby becomes the important target molecule of oncotherapy, the oncotherapy that with EGFRs is target probably is a kind of special and effective treatment plan.
The big characteristic of another of human entity tumour is exactly tumor neovasculature formation.When tumor cell number reaches 10 6, volume is at 2-3mm 3The time, oxygen and the nutritive ingredient of new vessel formation so that tumor tissues to be provided must be arranged.In the generation and metastasis forming process of tumour, the factor of inducing and promote new vessel to form is a lot of and occupy advantage, as vascular endothelial growth factor (VECF), fibroblast growth factor (bFGF), transforminggrowthfactor-(TGF-α), interleukin 8 (IL-8), tumor necrosis factor-alpha (TNF-α), plasminogen activating factors (PA) and matrix metalloproteinase (MMPs) etc., promote tumor neovasculature formation, and then carry nutrition to satisfy tumour cell fast breeding and the remote needs that shift.After new vessel generation (angiogenesis) hypothesis of the Folkman proposition seventies in last century tumour is proved, formed the treatment viewpoint of the anti-new vessel generation of tumour gradually.Adopt and suppress the factor such as Endostatin (endostatin), angiostatin (angiostatin), Interferon, rabbit (IFN-α, β, γ), thrombospondin, plasminogen activating factors inhibitor (PAI) and the Canstatin etc. that new vessel forms, suppress tumor neovasculature formation, the nutrition supply of tumour cell capable of blocking causes that tumour is because of the under-nutrition atrophy and even disappear fully and take off.There have been tens of kinds of angiogenesis inhibitors to enter clinical trial at present, wherein found by O ' Reilly that Endostatin received much concern in 1997, this molecule is the cracking segment of endogenous X VIII Collagen Type VI, have an effect at endotheliocyte, can suppress the hyperplasia and the migration of endotheliocyte, the blood supply of blocking-up tumour is taken off thereby make apoptosis of tumor cells or disappear.That Endostatin has is potent, nontoxic, non-immunogenicity, advantage such as have no drug resistance.But its protein molecular transformation period is short, and therapeutic dose is big, needs prolonged and repeated injection to use, and still can not produce on a large scale at present.
Summary of the invention
The object of the present invention is to provide a kind of oncolytic adenovirus mutant that has good potential applicability in clinical practice, can be used for the kinds of tumors treatment with the anticancer mechanism of multiple specific, this oncolytic virus and antioncogene recombinant chou overcome current replication-defective adenoviral vector (as Ad-p53) transhipment and express the shortcoming of antioncogene inefficiency, no target, overcome propagation replication type adenovirus carrier (as H101, ONYX-015) and only have shortcomings such as single antitumor mechanism, security be not good, its antitumor curative effect is improved, and security is improved.
