Towards understanding whether RA signaling might play a role in experimental FSGS, we compared Aldh1a2, Stra6, Rbp1 and Rdh10 mRNA expression in different PEC subtypes in FSGS mouse models, induced either by doxorubicin or by Cd2ap gene knockout, compared to healthy control mice. The gene discussed is RDH10; the disease is focal segmental glomerulosclerosis.
