[The GATA family in reproduction].

The GATA family proteins are a group of zinc finger transcription factors that are expressed in human and mammalian animals and play an important role in mammalian organ morphogenesis, cell proliferation and sex differentiation. GATA-4 and GATA-6 have been identified in the ovaries and testes of humans, mice, pigs and chickens. GATA-4 contributes to fetal male gonadal development by regulating the genes that mediate Müllerian duct regression and the onset of testosterone production. GATA-4 and GATA-6 are localized in and regulate the function of the ovarian and testicular somatic cells of fetal mice, especially granulosa cells, thecal cells, Sertoli cells and Leydig cells. GATA-4 is also present in the germ cells of fetal and prepubertal mice.
