MRFs基因家族对肉品质的影响

Effect of myogenic regulatory factors(MRFs) to meat quality

肌肉调节因子(MRFs)基因家族编码4种肌肉特异性转录因子,分别是MyoD、MyoG、Myf5和Myf6,它们是控制骨骼肌生成的关键调节因子,共同控制肌肉的生成。研究表明,这些肌肉特异性转录因子与肌肉生长和肉质有着密切的关系。本文就生肌调节因子MRFs家族的结构特性、作用机理及各成员对肉质的影响进行了综述,并对其研究进展及应用前景进行了讨论。

The family of Myogenic regulatory factors（MRFs）,encodes four kinds of muscle specmc transcription factors,including MyoD,MyoG,Myf5 and Myf6. MRFs members play important roles in the regulation of the generation of skeletal muscle,which control the myogenesis together. It has been reported that MRFs members have great correlation with muscle growth and meat quality. Character and action mechanism of MRFs gene family as well as their member＇s effect on meat quality were reviewed. And the potential applications of MRFs gene family were discussed in this paper.
