Expression analysis of the porcine Homeobox A11 gene and its association with litter size in Large White pigs
endometrium HOXA11 qPCR single nucleotide polymorphism litter size
2016/6/3
The homeobox A11 (HOXA11) gene, a well-known transcriptional regulator, plays a critical role in normal development of the uterus. In this study, the porcine HOXA11 gene, including its promoter region...
