Expression of StAR mRNA in the Early Piglet Testes / 中国生物工程杂志

The expressions of StAR (steroidogenic acute regulatory protein) mRNA in testes from 7,14,23 and 37 day-old piglets were studied by tissue in situ hybridization. The results indicated that in the testes of piglets, StARmRNA was expressed in Leydig cells of pig testes. The expression level of StARmRNA was lower in 7 days piglets but higher in 14,23,37 days. The results indicated that StAR gene played an important role in steroid biosynthesis.
