한우 비육기간 중 중성지방 생합성 관련 유전자의 발현양상

Abstract

Muscle fat content including intramuscular fat content(IMF) is the most important parameter in meat quality of cattle. Triacylglycerol is the major component of fat and is found in adipocyte and skeletal muscle. In present study, we carried out the determined of triacylglycerol contents and mRNA expression patterns of genes related with triacylglycerol biosynthesis such as ACSS2, GPAT, MGAT and DGAT in Hanwoo longissimus muscle using the real-time PCR. The triacylglycerol contents were continuously increased during the fattening stages. Interestingly, the contents of triacylglycerol were 7.4 fold higher(0.34 vs. 2.51, P
