[technical field]
The present invention relates to a kind of non-virus carrier of biological field, specifically, relate to a kind of unconformability and can delete non-virus carrier and construction process thereof and purposes.
[background technology]
Nowadays, transgenic technology, not merely for scientific research, has also been widely used in social production life.After induction versatile stem cell technology and transdifferentiation technological invention, it has been inexorable trend that transgenic technology is widely used in clinical.It is exactly security that present transgenic technology is used for one of them clinical obstacle: first, and foreign gene radom insertion, on genome, exists and causes the potential risk such as transgenation, gene silencing; Secondly, external source goal gene cannot be removed in time, and particularly when goal gene has into knurl effect, this is breakneck; Finally, some carriers need to express viral protein, and some viral proteins itself have carcinogenesis, and have higher immunogenicity, are very limited in clinical application.
After transgenic technology occurs, investigator does unremitting effort to the raising of the security of transgene carrier always.First be the appearance of the carrier of a class based on SV40, BPV, EBV virus.This kind of carrier achieves and carries out copying heredity with episomal form in eukaryotic cell, thus solves a difficult problem for vector gene radom insertion in host cell gene group.But the copying of this kind of carrier all needs the trans-acting factor of expressing viral source, and this proteinoid meeting transfaunation cell, such as: the carrier based on SV40 virus copies, need to express large T antigen (other albumen are provided by host cell), and large T antigen energy immortalization primary cell, when being applied to animal, oncogenic generation will be led.
1999, H.J.Lipps laboratory finds the S/MAR element of human origin to instead of SV40 large T antigen gene, and retain the replication origin (origin) of SV40, the carrier pEPI-1 built still can copy heredity with episomal form in Chinese hamster ovary celI, and when there is no resistance screening, 100 generations more than can be retained in Chinese hamster ovary celI.S/MAR sequence derives from mankind's interferon-β gene 5 ' end support adhesion district, and this kind of region is typical A/T enriched sequence, plays an important role in maintenance chromosome structure.PEPI-1 have passed through and repeatedly improves, and all concentrates on and simplifies sequence and reduce on CpG original paper, thus improves transfection efficiency and the expression efficiency of carrier, as pEPito.H.J.Lipps laboratory and Anthony Atala induced in versatile stem cell in experimentation on animals and the mankind respectively afterwards, demonstrated the feasibility based on S/MAR-SV40-Origin serial carrier.
As unconformable non-virus carrier, S/MAR-SV40-Origin carrier has improve very large security, but still there is hidden danger.In order to improve expression efficiency and transformation efficiency in inducing somatic reprogrammed process, usually can use strong promoter, and be applied to the clinical reprogrammed cell that needs and again break up, it is that we do not want to see that early stage foreign gene is broken up in the expression at this moment continued.
In sum, also need badly and build a kind of safer transfection carrier, to promote that induction versatile stem cell technology and transdifferentiation technology are applied to clinical treatment early.
