Moreover, we observed that MyHC IIA/X-AS is more enriched in fast-twitch muscle and represses slow-type gene expression and thereby maintains the fast phenotype. Furthermore, we found that MyHC IIA/X-AS acts as a competing endogenous RNA (ceRNA) that sponges microRNA-130b (miR-130b) ...
L,2001)。IIx型和IIa型、IIb型既有相似处也有不同处,IIx型肌 纤维与IIb型具有一样的酸稳定性,而氧化能力在IIa和IIb之间。 华中农业大学2011届硕士研究生学位论文 虽然不同的分类法对不同类型肌纤维的命名不同,但各种不同命名的肌纤维之 间有较高的相关性(BeeG,1999),慢收缩氧化型纤维和BR型纤维相当于I型...
1994年, Scohiaffin和Reggiani确定了哺乳动物中与肌纤维类型相对应的肌球蛋白重链MyHC的类型, 即肌球蛋白重链的亚型MyHCI(MyHCslow)、MyHCIIa、MyHCIIx和MyHCIIb分别对应I型、IIa型、IIx型和IIb型肌纤维[6]. 目前肌球蛋白重链(myosin heavy chain, MyHC)同功型被认为是决定肌纤维快、慢类型的主要决定因素[7...
The results are presented as the mean fold change of differences in MyHCs expression relative to that of the 1-day-old wild piglets (Figure 1). In the 1-day-old piglets (day 1), we found that although the MyHCembry, -I, -IIa and -IIx isoform mRNAs were abundant in both breeds, ...
