To explore the correlation between inosine monophosphate( IMP) contents and related gene expressions in pigs,high performance liquid chromatography method was used in this experiment in determining IMP contents of longissimus dorsi in crossbreed pigs including Duroc×Ningxiang,Berkshire×Ningxiang,Berkshire×( Berkshire×Ningxiang),( Berkshire×Ningxiang) ×( Berkshire×Ningxiang),and real-time quantitative PCR method was employed in detecting the expression levels of ADSL,GPAT and PURH genes. The results showed that IMP content in Berk...
