Description

A method of screening CREB signal path agonist or inhibitor
Technical field
The present invention relates to field of biotechnology, more particularly to a kind of screening CREB signal path agonist or inhibitor Method.
Background technique
CREB (cAMP response element-binding protein, cyclic adenosine monophosphate response element combination egg It is white) be a kind of Intracellular transcription factor, by be integrated to cyclic adenosine monophosphate response element (cAMP response element, CRE enhance the expression of downstream gene on).CREB signal path regulates and controls numerous vital movements, including tissue development, memory shape At, circadian rhythm etc..The abnormal generation that will lead to the diseases such as cancer, alzheimer's disease of the activity of CREB signal path, and It may finally lead to death.Therefore, sensitive to reliably detect CREB signal path activity and artificial adjustment CREB signal path Activity all has huge value for scientific research and clinical application.
HTLV-1 (Human T-lymphotropic virus 1, I type of human T-leukemia virus) is a kind of c-type RNA retrovirus causes global ten thousand people of 1500-2000 to infect, to cause the diseases such as adult T cell leukemia (ATL). There are three CRE in region by the LTR (long terminal repeat, long end repeat) of HTLV-1 genome, can be with host CREB in conjunction with and originate transcription to realizing self-replacation.Meanwhile HTLV-1 genome encoding Tax albumen can activate host CREB signal path and NF- κ B signal access are to promote viral own survival and breeding.Therefore, the region HTLV-1LTR is One sensitive CREB signal path responds original part, and Tax albumen is an efficient CREB signal path activator.
Polysaccharide is a kind of macromolecule biological activity substance being made of carbohydrate.In addition to directly providing energy, very much Polysaccharide has significant physiological function because of its unique property.Existing research surface, polysaccharide is in strengthen immunity, anti-swollen Tumor, anti-oxidant, antiviral, reducing blood lipid aspect all have ideal effect.Algal polysaccharides are the distinctive carbon aquations of a kind of algae Object is closed, usually there are some special physiological functions due to its distinguished structure.It is first to occupy the whole world for China's seaweed abundance Position, therefore also have algal polysaccharides resource abundant.Make full use of algal polysaccharides that will generate huge economy and society Value, the novel physiological function of excavating algal polysaccharides have potential scientific meaning and application value.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provides a kind of screening CREB signal path agonist or inhibition The method of agent obtains a HTLV-1 virus LTR regional sequence segment by screening and cloning, can rise in conjunction with host CREB Transcription begin to realize self-replacation, which is built into a luciferase reporter gene carrier system System, can be used for screening the agonist or inhibitor of CREB signal path.
A kind of CREB signal path luciferase reporter gene carrier, including firefly luciferase reporter gene and HTLV-1 virus LTR regional sequence segment, the HTLV-1 virus LTR regional sequence segment are located at firefly luciferase report Upstream region of gene and firefly luciferase reporter gene expression can be started after CREB protein activation.
The sequence of the HTLV-1 virus LTR regional sequence segment is as shown in SEQ ID No.1.The sequence is sick from HTLV-1 It clones and obtains in virus gene group, include three CRE, transcription can be originated in conjunction with host CREB to realize self-replacation.
The CREB signal path luciferase reporter gene carrier, sequence is as shown in SEQ ID No.2.The sequence Skeleton including pGL4.20 [Luc2/Puro] plasmid (Promega company), contains restriction enzyme BglII and HindIII Above-mentioned HTLV-1 virus LTR regional sequence segment is connected to pGL4.20 [Luc2/ by digestion method by restriction enzyme site Puro] plasmid BglII and HindIII between, obtain carrier be named as pGL4.20-HTLV-1-LTR-2.
The present invention also provides a kind of methods of screening CREB signal path agonist or inhibitor, include the following steps:
(1) the CREB signal path luciferase reporter gene carrier and internal reference carrier, positive control vector is same When transfection cell after cultivate, the internal reference carrier includes the Renilla luciferase reporter gene of sustainable stable expression, the sun Property control vector include that expression product is capable of the tax gene of activating ELK 1 B signal access;
(2) continue to cultivate after substance to be screened is added into cell culture medium;
(3) uciferase activity for detecting each groups of cells, if the groups of cells uciferase activity ratio of substance to be screened is added Not plus the groups of cells of substance to be screened is strong, then the substance to be screened is CREB signal path agonist;If substance to be screened is added Groups of cells uciferase activity than not plus substance to be screened groups of cells it is weak, then the substance to be screened be CREB signal path press down Preparation.
The internal reference carrier is pRL-CMV, and sequence is as shown in SEQ ID No.3.Internal reference carrier pRL-CMV is purchased from Promega company includes Renilla luciferase reporter gene, can sustainedly and stably give expression to renilla luciferase, be used for Error is eliminated as internal reference.
The positive control vector is pcDNA3.1-Tax, and sequence is as shown in SEQ ID No.4.The positive control vector is Tax gene insertion pcDNA3.1 plasmid (pcDNA3.1 plasmid is purchased from Promega company) in HTLV-1 genome is obtained, The Tax albumen of tax gene coding in HTLV-1 genome can activate host CREB signal path to promote virus itself Survival and breeding, since host cell itself CREB signal path activation level is lower, so the CREB signal path is double After in luciferase reporter gene vector introduction host cell, the expression of firefly luciferase reporter gene has very much Limit, it is not easy to detect, by importing tax gene expression Tax albumen again, host's CREB signal path can be activated, to make firefly The expression of fireworm luciferase reporter gene is greatly improved, and convenient for detection, reduces detection error.
Application the present invention also provides fucoidin as CREB signal pathway inhibitor.The use of the fucoidin Concentration is 1 μ g/mL -1mg/mL.The present invention screens a variety of polysaccharide using the above method, and finally screening obtains fucoidin to CREB Signal path is inhibited, can be used as the inhibitor of CREB signal path.
The present invention by the way that HTLV-1 virus LTR regional sequence segment is cloned into luciferase reporter gene carrier, A kind of CREB signal path luciferase reporter gene carrier is made, can be used for detecting CREB signal path activity, it can also With the agonist or inhibitor for screening CREB signal path.The rock algae of Targeted-control CREB signal path is screened simultaneously Polysaccharide, fucoidin negative regulation inhibit CREB Pathway Activation.
