Expression of Myogenic Factor Genes Measured in Musculus longissimus lumborum of Heifers and Bulls at Different Time Points
Myogenic factor 5 (MYF5), Myogenic factor 6 (MYF6), Myogenic differentiation factor 1 (MYOD1) and Myogenin (MYOG) belong to the myogenic regulatory factor (MRF) family of transcription factors that regulate myogenesis, skeletal muscle differentiation and fibre development in cattle. Their genes are suitable candidates for molecular markers of growth, economically relevant body measurement traits and meat production traits. However, little is known regarding the expression of bovine myogenic factor genes throughout life cycle. The objective of this study was to measure the mRNA expression of the four MRFs involved in transcriptional regulation in Musculus longissimus lumborum (MLL) of heifers and bulls at three time-points during the growth period.
