GPRC6A and prostate carcinoma: Androgen reportedly suppresses autophagy in Sertoli cells and the human prostate cancer cell line LNCap through its nuclear AR.[45, 46] In microglia, AR expression levels are significantly low,[47] despite the expression of the non‐genomic testosterone receptor GPRC6A, suggesting that testosterone‐GPRC6A signaling may be the dominant signaling pathway.
