Up-regulation of gonadotropin mRNA-expression at the onset of gametogenesis in the roach (Rutilus rutilus): Evidence for an important role of brain-type aromatase (cyp19a1b) in the pituitary
Popis výsledku v původním jazyce
The present study characterized changes in key parameters of reproduction in adult roach (Rutilus rutilus) from Lake Grosser Mueggelsee (Berlin, Germany) during natural gametogenesis. Fish of both sexes were sampled in monthly intervals between April andAugust in order to cover the onset of gametogenesis. Investigated parameters included gonad histology, plasma levels of 17 beta-oestradiol (E2), testosterone (T), 11-ketotestosterone (11-KT), and 17,20 beta-dihydroxy-4-pregnen-3-one (17,20 beta-P) as well as the expression of gonadotropin subunits in the pituitary. Furthermore, the mRNA-expression of brain-type aromatase (cyp19a1b), androgen receptor (ar), and estrogen receptor isoforms was studied at the pituitary level. The onset of gametogenesis - as indicated by follicles with cortical alveoli in females and first spermatogonia B in males - was observed in July, accompanied by a significant up-regulation of follicle-stimulating hormone beta (fsh beta) mRNA in the pituitary in both
