In order to elucidate the roles of 17beta-HSDs in fish gonadal steroidogenesis, three types of 17beta-HSDs (17beta-HSD1, 17beta-HSD8 and putative 17beta-HSD12) were cloned and characterized from the Nile tilapia, Oreochromis niloticus. The cloned cDNAs of 17beta-HSD type 1, 8 and 12 were 1504, 1006 and 1930 bp long, with open reading frames encoding(More)
In many vertebrates, estrogens are necessary to promote the growth and differentiation of the female reproductive system during development, and have important reproductive roles in both males and females. Medaka (Oryzias latipes) has three estrogen receptor (ER) subtypes, ERα, ERβ1 and ERβ2. To evaluate the three medaka ER (mER)-ligand interactions, we(More)
Despite identification of several sex-determining genes in non-mammalian vertebrates, their detailed molecular cascades of sex determination/differentiation are not known. Here, we used a novel RNAi to characterise the molecular mechanism of Dmy (the sex-determining gene of medaka)-mediated masculinity in XY fish. Dmy knockdown (Dmy-KD) suppressed male(More)
