Abstract: The objective of this study was to assess the differential expression of CaN and CaMK during the improvement of lipogenesis in 2 strain chickens muscles. Twelve birds for each strain were slaughtered at 8 weeks for AA chickens and at 8, 16 weeks for BJY chickens. The results showed that the content of IMF and the expression of PPARγ, FAT/CD36 and FAS in muscle were significantly at 16 weeks higher than those for AA at 8 weeks and BJY at 8 weeks (p<0.05). Compared with AA chickens at 8 weeks, BJY at 16 weeks showed the significantly lower expression of CaN subunits and CaMK IV in muscle (p<0.05). But the expression of CaMK II was significantly higher at 16 weeks than 8 weeks in muscle (p<0.05). The expressions of C/EBPβ, SREBP1 and PPARγ were dramatically enhanced by CsA (p<0.05). KN93 dramatically repressed the expression of those lipogenic gene (p<0.05). These results indicated that CaN and CaMK had different effects on adipogenesis in the muscle of chickens.
