High impact information on amh

  • AMH was detected in growing oocytes, the ovarian follicular layer and testicular Sertoli cells, similar to the mammalian pattern, suggesting a conserved role between zebrafish and mammalian AMH [1].
  • In adult ovaries, amh and cyp19a1a were expressed in granulosa cells surrounding the oocytes, and sox9b was expressed in a complementary fashion in the ooplasm of oocytes [2].
  • In adult testes, amh and sox9a were expressed in presumptive Sertoli cells [2].
  • In differentiated gonads of juveniles, amh showed a sexually dimorphic expression pattern [2].
  • In male mammalian embryos, Sox9 activates expression of Amh, which initiates the regression of the Mullerian ducts and inhibits the expression of aromatase (Cyp19a1), the enzyme that converts androgens to estrogens [2].
