Abstract
Sex determination and sexual differentiation pathways are highly conserved between marsupials and eutherians. There are 2 different pathways of prostaglandin D2 (PGD2) synthesis: prostaglandin D synthase (PTGDS) and haematopoietic prostaglandin D synthase (HPGDS). PGD2 regulates the subcellular localization of SOX9 during gonadal sexual differentiation. To investigate the function of PGD2 in the tammar gonad, we cultured undifferentiated male gonads in the presence of the HPGDS inhibitor HQL-79 and female gonads with exogenous PGD2 to mimic activation of the PTGDS-PGD2 pathway. Tammar PTGDS and HPGDS have only 50% similarity with mouse and human orthologues, but functional domains are conser..
