Abstract: The study was aimed to reveal the temporal and spatial expression of ACTC1 gene in Qinchuan cattle,which will lay the foundation for further research on the functions of ACTC1 gene in muscle development and fat deposition of beef cattle.Real-time quantitative PCR was used to detect the expression of ACTC1 gene in 13 tissues of 24-month-old adult Qinchuan cattle and 12 kinds of tissues of 4-day-old Qinchuan cattle.At the same time,the expression characteristics of this gene in myoblasts and preadipocytes of Qinchuan cattle at different differentiation stages (0,2,4,6 and 8 d) were studied and analyzed.The results showed that the expression of ACTC1 gene was the highest in heart of Qinchuan cattle,followed by skeletal muscle.Except for rumen and kidney,the expression of ACTC1 at 24-month-old adult cattle was significantly or extremely significantly higher than that at 4-day-old newborn cattle (P<0.05;P<0.01).The expression of ACTC1 gene in myoblasts increased at first and then decreased along with the myoblasts differentiation.On the 2nd,4th,6th and 8th day of myoblast differentiation,the expression of ACTC1 gene was significantly different from that on 0th day (P<0.01),which were 2.6,4.7,5.6,and 4.2 times of 0th day,respectively.This was consistent with the differentiation rate of myoblasts.The expression trend of ACTC1 gene in adipocytes decreased at first and then increased.The expression levels on 2nd day and 4th day were significantly different from those on 0th day (P<0.01).From the 2nd day of differentiation,the expression increased with the adipocyte differentiation.The expression of ACTC1 gene was the highest in muscle tissues (myocardium and skeletal muscle) of cattle,and its expression characteristics were consistent with the overall trend of muscle cell differentiation.In addition,there was also a certain rule of ACTC1 gene expression in adipocytes.In summary,it was speculated that ACTC1 gene might affect the growth and development of muscle tissue and fat deposition in cattle.
