c C major [minor] C大[小]调。 a C-spring C字形(承力)弹簧 (=Cee-spring)。 CCCL=350. C3丙等(的),体格劣等(的)。 (a C3 concert 第三流音乐会)。 C and A Pocket 〔美国〕无业游民做在上衣里用来装多余粮食的口袋 (Chicago and Alton pocket)。 C and S 【美军】整洁而严肃的 (=clean and sober)。
C - kit is a receptor tyrosine protein kinase on the cellular membrane , while c - myc is a transcription regulatory factor in the nucleus Kit是位于细胞膜上的受体酪氨酸蛋白激酶, myc是位于细胞核内的转录调节因子。
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 在信号转导系统中, kit是干细胞因子( steelcellfactor , scf )的膜上受体,位于信号级联的上游,而myc处于下游。
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蛋白可能作为c - kit / scf信号转导系统的靶蛋白之一,以同源二聚体与max或mxil形成异源二聚体作用于靶基因的特有序列,激活或抑制靶基因的转录活性。
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 精母细胞周围的囊细胞可能合成scf样蛋白,特异地识别精母细胞膜上的c - kit受体,并刺激c - kit发生二聚化、自体磷酸化,激活胞内酪氨酸激酶活性,活化具有“ sh _ 2结构域”的靶蛋白,可能通过一系列信号级联,最终激活与减数分裂的相关蛋白或基因。
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 结果表明, kit在多伊棺头蟋精子发生中期至后期的精母细胞膜上有阳性颗粒,在精巢和受精囊内精子头部残留的细胞质内也有阳性表达;但在出生后卵子发生过程中,发育中的卵母细胞上无阳性表达。
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 该细胞系是典型的上皮样细胞,体外生长时成“铺路石”样排布;在电镜下观察,细胞核质比大,胞浆中除一些线粒体和核糖体外缺乏其他细胞器;在体外培养时细胞可以保持不分化状态,表达卵圆胆管细胞的分子标志,如ck14 , ck19 , ov6 , oc
