Description
Technical field
The present invention relates to a kind of insect cell line and its preparation method and application, especially one derives from insect pupa ovary tissue, by the clone of carcinogen N-methyl-N'-nitro-N-nitroso-guani dine (MNNG) Induction Transformation, and by the method for outer being immortalized of the Induction Transformation clone of prosthesis, belong to transgenic animal technical field.
Background technology
Insect is the biotic population of most species in the world, has abundant cytogenetics system, no matter scientific research or practical application, and insect cell line comes into one's own day by day.Insect cell line is the important tool of the scientific researches such as physiology, developmental biology, cytobiology, molecular biology and biological chemistry always; It is the chief component composition of the rhabdovirus expression vector system of one of four large expression systems, can express the exogenous protein with great economy value and scientific meaning; As bio-reactor amplification insect baculovirus, particularly contain the recombinant baculovirus of foreign gene, for the R&D and production of viral organism sterilant.From Grace within 1962, setting up first can tussah (Autheraea pernyi) ovary cell line of cultured continuously since, in the time of 40 years, the insect cell line of having set up exceedes 500 kinds, they derive from respectively 170 various insects, comprising lepidopteran, Diptera, Homoptera, Hymenoptera, Orthoptera and Coleoptera etc.Although insect cell is cultivated the favor that has been subject to numerous scientists, also obtained in recent years deepening constantly and developing, but the foundation of a strain insect cell line often needs to consume a large amount of time and efforts, especially compared with the increasingly mature various culture technique of mammalian cell, the cultivation means of insect cell are aging, single, lack innovation.
Up to the present, have 6 strains from the clone of beet armyworm (Spodoptera exigua), conventionally derive from newly hatched larvae, hemocyte and fatty body.First clone of beet armyworm UCR-SE-1 is by Gelernter and Federici (Gelernter, W.D. with B.A.Federici J.Invertebr.Pathol.1986,48:199～207) set up, the second strain clone Se3FH is the (Hara such as Hara, K., K.Tsuda, M.Funakoshi and T.Kawarabata In Vitro Cell.Dev.Biol.1993,29A (12): 904～907) set up, two strain clones all derive from beet armyworm newly hatched larvae tissue.The 3rd strain Le-H-HNU7 clone and the 4th strain SeHe920-1a clone derive from beet armyworm hemocyte, and this clone is to Spodoptera litura nucleopolyhedrosis virus sensitivity.Other two strains are the clone that derives from beet exigua larvae fatty body of being set up by this laboratory, and this two strains clone is all very responsive to laphygma exigua nuclear polyhedrosis virus and autographa california nuclear polyhedrosis virus.Although the relevant report of the existing beet armyworm clone of aforementioned documents, but up to the present, also do not derive from the clone of beet armyworm ovary.The ovary of insect is normally paired, is the place of ovum initiation and development.Ovary is made up of ovariole (ovariole), and in all kinds of insects, the number of ovariole is widely different, and lepidopterous insects is generally 4,6 or 8.Since Grace utilizes ovary tissue to set up first insect cell line, ovary is the vital tissue source of Establishment of Cell Line always.The ovary tissue that the pupa that dissection will be sprouted wings obtains is easier to operation, reduces opportunities for contamination.Still there is very large demand in a greater variety of insect cell lines, sets up the new clone that derives from insect ovary, and the rhabdovirus expression vector system more efficiently that builds is very significant.
Traditional insect cell line establishment method is normally waited for cell spontaneous transformation, and because condition is difficult to control, usually due to pollution, all that has been achieved is spoiled.After cultured cell in vitro successfully goes down to posterity, in the time cultivating certain algebraically, can enter growth-inhibiting state, vitality obviously weakens, and multiplication capacity declines, and cessation of growth cessation is also final dead.It is the important means that obtains cellular immortalization that artificial induction's cultured cell in vitro transforms.Under the mutagen of artificial design, cell is transformed, transformation efficiency is higher, and passage cell growth cycle is long, proterties is stable.In cell cultivation process, manual-induced conversion comprises the various mutagen impacts such as chemistry, physics, biology (virus) in vitro.Under mutagenic compound exist, the cell DNA of vitro culture damages, but now cell is still survived, and cell carries out the self-regeneration of DNA for the existence of oneself, because just having the enzyme of many self-regeneration DNA, cell itself exists, its repair process is complicated, but in this complicated DNA repair process, mis repair also can occur unavoidably, the reparation of mistake can cause the change of DNA structure, repair and finish, this altered DNA structure is just fixed, and irreversible.This just indicates that hereditary change has occurred cell DNA.Under suitable condition, this cell just can continuous growth and breeding.
Transform with chemical carcinogen induced animal normal cell system separately, all have report (Nes now S, Garland H, Curt is G.Cancer let t, 1989 both at home and abroad; 47 (1-2): 91～97.; Tsuch iya T, Umeda M.Carcinogenes is.1995; 16 (8): 1887～1894.).N-methyl-N'-nitro-N-nitroso-guani dine (MNNG) is the nitrous acid amides representative of synthetic, for conventional chemical carcinogens, can there is covalent attachment with the 0-6 position of DNA guanine in its alkanisation group, form adducts, cause base mispairing, thereby bring out cell transformation (model rainbow, Dong Huifen, Jiang Mingsen, Ming Zhenping, Zhong Qinping, the research of effect of MNNG on cytoskeleton of cultured cells from adult Schistosoma japonicum, sick magazine, 2001,20 (6): 401-403 learned of place of china).According to domestic, N-methyl-N'-nitro-N-nitroso-guani dine is used for studying the propagation of mammalian cell.For example, the impact of the N-methyl-N'-nitro-N-nitroso-guani dine that recklessly waits report for 1994 quietly on vascular smooth muscle cell proliferation, the DNA that has obviously strengthened cell is synthetic, has significantly promoted division growth (Hu Jing, the Wen Jinkun of cell, Wei Suzhen, Zuo Lianfu, the impact of N-methyl-N'-nitro-N-nitroso-guani dine on vascular smooth muscle cell proliferation, Chinese physical medicine magazine, 1994,16 (4): 211-213).Zhang Wengeng etc. utilize MNNG Induction Transformation and have set up human neofetus dermal fibroblasts system (Zhang Wengeng, Xu Gang, Wang Yanping, Chen Xiaobing, the foundation of the human neofetus dermal fibroblasts system of MNNG Induction Transformation, 1994,16 (3): 125-128).Aspect invertebrates, MNNG focuses mostly in the research to Cells of Schistosoma japonicum inducing action, to the effect of Cultured Cells From Adult Schistosoma Japonicum skeleton, Phosphoric acid esterase and bird ammonia enzyme decarboxylase; The impact of nucleolus organizer region's organizer-region-associated Proteins; Research to Cultured Cells From Adult Schistosoma Japonicum propagation etc. all has report (model rainbow, Dong Huifen, Jiang Mingsen, Ming Zhenping, Zhong Qinping, the research of effect of MNNG on cytoskeleton of cultured cells from adult Schistosoma japonicum, the sick magazine of learning of place of china, 2001,20 (6): 401-403; Liu Qing, Dong Huifen, Jiang Mingsen, Ming Zhenping, Zhong Qinping, the research of Mnng On Phosphatase In The Cultured Cells From Adult Schistosoma Japonicum impact, Chinese prevention and cure of snail fever magazine, 2002,14 (1): 14-16; Model rainbow, Huang Min, Wang Qian, Li Manjun, the preliminary study of MNNG to the effect of chistosoma japonicum cell of adult ornithine decarboxylase activity, Chinese parasitology and parasitic disease magazine, 2002,20 (1): 35-36; Zhong Qinping, Ming Zhenping, Jiang Mingsen, Dong Huifen, MNNG induces the impact on Cultured Cells From Adult Schistosoma Japonicum nucleolus organizer region organizer-region-associated Proteins, Chinese prevention and cure of snail fever magazine, 2009,21 volumes (5): 378-381; Dong Huifen, Jiang Mingsen, Ming Zhenping, Zhong Qinping, Yang Mingyi, the research of N-methyl-N'-nitro-N-nitroso-guani dine induction Cultured Cells From Adult Schistosoma Japonicum propagation, Chinese public health, 2000,16 (10): 883-884).
