Abstract:

The objective of the present study was to investigate the expression profile of CaN/NFAT-dependent pathway genes, and their correlation analysis in 2 phenotypically distinct skeletal muscles were studied in chicken during the early development. qRT-PCR was used to detect the mRNA expression of CnAα, CnB1, NFATc3, MEF2C and PPARGC1A genes in lateral gastrocnemius and extensor digitorum longus of Recessive White chicken at 0,1,3,5,7 and 9 week age, the correlation among expression of these genes was analyzed. The results showed that the expression trends of all the genes between 2 phenotypically distinct skeletal muscles were similar except CnB1, and the expression level of these genes in 2 phenotypically distinct skeletal muscles was all raised from 7 to 9 week age. Comparison among the expression of these genes in 2 phenotypically distinct skeletal muscle showed that the expression level of PPARGC1A in the lateral gastrocnemius was higher than that in the extensor digitorum longus at each detected age, and the expression level of other 4 genes in the lateral gastrocnemius was higher at 3 week age and lower at 7 and 9 week age than that in the extensor digitorum longus. Correlation analysis among the 5 genes expression levels in the 2 phenotypically distinct skeletal muscles showed that there was a negative correlation between the CnAα and 2 genes (NFATc3 and PPARGC1A), and positive correlations among the expression of other genes. Overall, the expression patterns of CnAα, CnB1, NFATc3, MEF2C and PPARGC1A genes in chicken skeletal muscle are age and phenotype specific, which may be related to the regulation of the myofiber growth and type transition.
