已经在鸡非肌肉细胞中鉴定了编码两种不同的约200 kD的非肌肉肌球蛋白重链(MHC)的两种不同mRNA,这与Katsuragawa等人的结果一致(Katsuragawa,Y.,M. Yanagisawa,A. Inoue和T.正树1989. EUR. 184:611-616)。在本文中,我们定量的mRNA编码的两个MHC的含量在一些不同的组织中使用RNA印迹分析与两个特定的寡核苷酸探针。我们的研究结果表明,编码MHC-A和MHC-B的mRNA的相对含量以组织依赖的方式不同。因此,编码MHC-A与MHC-B的mRNA的比例从脾和肠上皮细胞中的大于9:1变化到肾中的6:4和脑中的2:8。在血清饥饿培养的鸡胚成纤维细胞中,研究了血清对MHC mRNA表达的影响。血清刺激导致编码MHC-A的mRNA增加三倍,编码MHC-B的mRNA减少三倍。使用SDS聚丙烯酰胺凝胶,我们已经分离出两个非肌肉MHC亚型(198和196 kD),可以区分彼此的二维肽图的胰凝乳蛋白酶。我们提供的初步证据表明,MHC-A mRNA编码的196-kD多肽和MHC-B mRNA编码的198-kD多肽。
Two different mRNAs encoding two different nonmuscle myosin heavy chains (MHCs) of approximately 200 kD have been identified in chicken nonmuscle cells, in agreement with the results of Katsuragawa et al. (Katsuragawa, Y., M. Yanagisawa, A. Inoue, and T. Masaki. 1989. Eur. J. Biochem. 184:611-616). In this paper, we quantitate the content of mRNA encoding the two MHCs in a number of different tissues using RNA blot analysis with two specific oligonucleotide probes. Our results show that the relative content of mRNA encoding MHC-A and MHC-B differs in a tissue-dependent manner. Thus the ratio of mRNA encoding MHC-A versus MHC-B varies from greater than 9:1 in spleen and intestinal epithelial cells, to 6:4 in kidney and 2:8 in brain. The effect of serum on MHC mRNA expression was studied in serum-starved cultures of chick embryo fibroblasts. Serum stimulation results in a threefold increase in the mRNA encoding MHC-A and a threefold decrease in mRNA encoding MHC-B. Using SDS polyacrylamide gels, we have separated two nonmuscle MHC isoforms (198 and 196 kD) that can be distinguished from each other by two-dimensional peptide mapping of chymotryptic digests. We provide preliminary evidence that the MHC-A mRNA encodes the 196-kD polypeptide and that the MHC-B mRNA encodes the 198-kD polypeptide.
