猪MYOZ2基因表达及其功能分析
Expression and Functional Analysis of MYOZ2 Gene in Pigs
摘要
Abstract
This experiment detected the expression of MYOZ2 gene in semi quantitative test and explore the effect of MYOZ2 gene on the growth performance of pigs.Semi quantitative test results showed that MYOZ2 gene was highly expressed only in the heart and dorsal muscle of pig,indicating that the expression of MYOZ2 gene in muscle was specific.Fluorescence quantitative PCR results showed that MYOZ2 gene's expression in longissimus muscle of slow-growth miniature pig (TP and DSP) was significantly lower than that of fast-growth introduction pig (YY and LL) (P＜0.01),and MYOZ2 gene's expression difference was not significant (P＞0.05) between TP and DSP,YY and LL.(Conclusion)MYOZ2 gene was only expressed specificly in pig cardiac and longissimus muscle.It was higher in muscle of fast-growth pig than that of slow-growth pig and it may regulate muscle growth through calcium-NFAT signaling pathway preving,MYOZ2 gene is an important candidate gene of pig growth traits.关键词
