Activin A and its inhibitors follistatin and inhibin play key roles in development and function of the male reproductive tract. Quantitative (q) polymerase chain reaction (PCR) was used to evaluate the expression of Inhba (the gene encoding activin A subunits), Inha and Inhbb (genes encoding the inhibin B subunits), as well as the genes for follistatin (Fst) and follistatin-like 3 (Fstl3) and the activin receptor subunits, in the male mouse reproductive tract. A qPCR assay that discriminated between the two follistatin variants of Fst288 (tissue-bound form) and Fst315 (circulating) was established. Activin A protein was measured by ELISA, whereas the inhibin α-subunit and total follistatin p..
