摘要: 旨在获得敲减FST基因的猪胎儿成纤维细胞,并探讨对相关基因表达的影响。将构建成功并鉴定准确的发夹RNA真核表达载体FR1-shRNA利用脂质体转染至猪胎儿成纤维细胞中,并进行G418筛选,获得稳定转染细胞株,并利用Real-time检测了相关基因表达的变化。结果表明,在稳定转染的细胞株中,FST基因的表达受到显著抑制,结果导致了ActivinRⅡA、Myostatin和Bmp4基因的表达出现下调趋势,并且极显著地降低MyoD基因的表达。

Abstract: In order to obtain FST gene knock-down pig fetal fibroblast cells and investigate the effects of related gene’s expression, the short hairpin RNA eukaryotic expression vectors for FST was constructed and transfected into pig fetal fibroblast cells. After screened with G418, transfected stable cell clones were obtained, and Real-time PCR was used to detect FST-related genes change in gene’s expression. The results showed that in stably transfected cell lines, FST gene expression was significantly inhibited, then resulting in the expression of ActivinRⅡA, Myostatin and Bmp4 downward trend, and the expression of MyoD gene very significantly reduced.
