Changes in expression profiles of genes related to sexual maturation during spermatogenesis in testes of early-maturing male Atlantic salmon parr, Salmo salar
We investigated the expression of genes encoding proteins involved in sex steroid biosynthesis (Ff1b, StAR, P450scc, 3b-HSD, P450c17, P45011b and11b-HS D and AMH homolog during early sexual maturation in male Atlantic salmon parr. Male salmon parrs were sampled during their first sexual maturation....
