Canonically, the biological activities of RA are mediated by nuclear RA receptors.

Tretinoin 293-295 stimulated by retinoic acid gene 8 Mus musculus 176-181 31682623-3 2019 In this study, using a germ cell culture system, we investigated (1) whether RA treatment activates any mitogen-activated protein kinase (MAPK) pathways in fetal germ cells at the time of sex differentiation, and (2) if this is the case, whether the corresponding RA-stimulated signaling pathway regulates Stra8 expression in fetal germ cells and their entry into meiosis. Tretinoin 77-79 stimulated by retinoic acid gene 8 Mus musculus 306-311 31682623-5 2019 MEK1/2 inhibitor (U0126) treatment suppressed the mRNA expressions of RA-induced Stra8 and meiotic marker genes (Rec8, Spo11, Dmc1, and Sycp3) in both XX and XY fetal germ cells. Tretinoin 70-72 stimulated by retinoic acid gene 8 Mus musculus 81-86 31682623-7 2019 Taken together, our results suggest the novel concept that the RA functions by stimulating the ERK1/2 pathway and that this activity is critical for Stra8 expression and meiotic progression in fetal germ cells.
