Abstract: The expression of Krox20 gene of Yorkshire in 1，6 months and Wild boar in 1 month were analyzed by using semi-quantitative RT-PCR method and detected in adipocyte and adipose tissue. The results showed that Krox20 gene was expressed in heart, liver, spleen, lung, kidney, stomach, large intestine, small intestine, fat, ovary, uterus, muscle; The expression level of Krox20 gene was different in the detected tissues, it was highly expressed in heart, liver, fat; The expression mode of 1 month Yorkshire and Wild boar were similar, there was little species-specificity; With the age increasing, the expression of Krox20 gene was gradually decreased in adipose tissue,it had the highest expression level at 1 month, and reached the least at 9 month; In the research of adipocyte, the expression of Krox20 gene was not detected in preadipocyte, but detected in adipocyte after induced for 5 hours.
