Comparative transcriptomic analysis of skeletal muscle tissue during prenatal stages in Tongcheng and Yorkshire Pig using RNA-seq. Sus scrofa

The transition during myogenesis is accompanied by a multitude of changes in gene expression, and the transcriptional events that underlie these processes have not yet been fully elucidated. Tongcheng pigs (TC) and Yorkshire pigs (YK) represent Chinese local pigs and western pigs, respectively. To investigate the genes involved in regulating different periods of skeletal muscle development between TC and YK, we herein performed a comprehensive research of porcine transcriptome from longissimus muscle during 5 skeletal muscle developmental stages, including 40, 55, 63, 70, 90 dpc (days post coitum) using RNA-seq technology.
