A series of experiments were carried out by the RT-PCR method to probe the difference of mRNA expression of porcine myostatin gene in three muscular tissues, namely skeletal muscle, heart muscle and stomach smooth muscle. mRNA expression was found in all muscular tissues. mRNA expression in skeletal muscle and heart muscle was more active than in the stomach smooth muscle.
