Porcine CFL2b gene is expressed mainly in skeletal muscle, it affects muscle development and myofibrillar formation. In order to study the relationship between CFL2b gene and muscle fiber trait, stable C2C12 cell clones groups expressing porcine CFL2b gene were obtained by directed cloning and gene transfection technology. The expression of pEGFP-N1–CFL2b were detected using GFP fluorescence and Western Blotting. The expression level of myosin heavy chain (MyHC) isoforms (2x.2b and slow) in C2C12 were determined using Real-time PCR. Result showed that MyHC 2x gene and MyHC 2b genes were obviously up-regulated, MyHC1/slow gene not significant. The research indicated porcine CFL2b gene correlated to muscle fiber trait. And it was associated with pork quality. Porcine CFL2b gene can possible be regarded as a candidate gene for pork quality [Acta Zoologica Sinica 54(6): 1014–1019, 2008].
