research Allopregnanolone-mediated protective effects of progesterone on tributyltin-induced neuronal injury in rat hippocampal slices
Progesterone protects neurons from damage by converting to allopregnanolone, which works through GABAA receptors.
research Sdr16c5 and Sdr16c6 control a dormant pathway at a bifurcation point between meibogenesis and sebogenesis
Sdr16c5 and Sdr16c6 genes regulate a key point in lipid production that affects eye and skin gland function.
