C - kit is a receptor tyrosine protein kinase on the cellular membrane , while c - myc is a transcription regulatory factor in the nucleus Kit是位于細(xì)胞膜上的受體酪氨酸蛋白激酶, myc是位于細(xì)胞核內(nèi)的轉(zhuǎn)錄調(diào)節(jié)因子。
In the signal transduction system , c - kit is in the upstream as the stem cell factor ( scf ) receptor , while c - myc in the downstream as a target protein 在信號轉(zhuǎn)導(dǎo)系統(tǒng)中, kit是干細(xì)胞因子( steelcellfactor , scf )的膜上受體,位于信號級聯(lián)的上游,而myc處于下游。
At last , the related proteins and genes in meiosis are activated through a series of signal proteins , c - myc is maybe one of the target proteins in the c - kit / scf signal transduction system . it activates or suppresses the target genes in forms of myc - max , myc - myc , max - max , max - mad or max - mxil Myc蛋白可能作為c - kit / scf信號轉(zhuǎn)導(dǎo)系統(tǒng)的靶蛋白之一,以同源二聚體與max或mxil形成異源二聚體作用于靶基因的特有序列,激活或抑制靶基因的轉(zhuǎn)錄活性。
The cyst cells enclosing spermatomeres maybe synthesize a kind of scf - like protein , which can recognize specially the c - kit receptor on the cellular membrane of spermatomeres . then c - kit is activated , dimerizing and autophosphorylating . at the same time , the tyrosine kinase domain of c - kit is activized , which phosphorylates the proteins that have sh2 domain 精母細(xì)胞周圍的囊細(xì)胞可能合成scf樣蛋白,特異地識別精母細(xì)胞膜上的c - kit受體,并刺激c - kit發(fā)生二聚化、自體磷酸化,激活胞內(nèi)酪氨酸激酶活性,活化具有“ sh _ 2結(jié)構(gòu)域”的靶蛋白,可能通過一系列信號級聯(lián),最終激活與減數(shù)分裂的相關(guān)蛋白或基因。
In order to study the regulatory mechanism in gametogenesis of loxoblemmus doenitzi , the special expression of c - kit and c - myc is investigated by immunohistochemical method . the results show that there are kit positive protein granules on the cellular membrane of spermatomeres from metaphase i to anaphase ii , and in the head of mature spermatozoa not only in the testis but also in the spermatheca 結(jié)果表明, kit在多伊棺頭蟋精子發(fā)生中期至后期的精母細(xì)胞膜上有陽性顆粒,在精巢和受精囊內(nèi)精子頭部殘留的細(xì)胞質(zhì)內(nèi)也有陽性表達(dá);但在出生后卵子發(fā)生過程中,發(fā)育中的卵母細(xì)胞上無陽性表達(dá)。
In our culture condition , the lepcs express oval cell markers ck 19 , ck 14 , ov6 and oc . 10 , but not oc . 2 and oc . 5 . the cells also express c - met , the receptor for hepa tocyte growth factor ( hgf ) . antigens traditionally associated with haematopoietic stem cells , including c - kit , thy - 1 and cd 34 , can be expressed by oval cells 該細(xì)胞系是典型的上皮樣細(xì)胞,體外生長時(shí)成“鋪路石”樣排布;在電鏡下觀察,細(xì)胞核質(zhì)比大,胞漿中除一些線粒體和核糖體外缺乏其他細(xì)胞器;在體外培養(yǎng)時(shí)細(xì)胞可以保持不分化狀態(tài),表達(dá)卵圓膽管細(xì)胞的分子標(biāo)志,如ck14 , ck19 , ov6 , oc
