INFLUENCE OF HORMONES ON mRNA ABUNDANCE OF FATTY ACID SYNTHETASE IN LONISSINUS DORSI MUSCLE OF PIG IN VITRO

摘要

IntroductionFlavour and tenderness are key components contributing to a good eating experience. Intramuscular fat extracted from the Longissimus muscle was related to flavour and juiciness, with marbling related to percent intramuscular fat. Sutdies showed that one of Chinese local species, Rongchang, had higher intramuscular fat content in muscle(Pang et al.,2006).Muscle tissues and cells undergo a regulated growth and differentiation processes, as well as substrate utilization and energy partitioning, were affected by a range of factors.Recently, the (signaling) interaction between myogenic cells and adipocytes had been found which was considered as a significant role in regulation of the rate and extent of adipogenesis,myogenesis,and lipogenesis/lipolysis (Boone et al., 2000). Studies showed that insulin (INS), somatotropin (ST),epinephrine (Epi) and glucagon (GCG) were hormones participating in the processes of lipogenesis/ lipolysis in animals.
