The association of haplotypes inIGFBP-3gene promoter region and tissue expressions in three pig breeds

Bama Xiang pig (BM) and Tibetan mini-pig (TM) are used as experimental animals in China; however, the dwarf molecular mechanisms of these Chinese local pig breeds are unknown. IGFBP-3 affects animal growth, carcass and meat quality. The aim of this study was to identify the polymorphisms in the promoter of the IGFBP-3 and analyse their effect on the IGFBP-3 mRNA expression level in liver and muscle tissues. High-density single-nucleotide...
