PKM2 Is a Potential Diagnostic and Therapeutic Target for Retinitis Pigmentosa

<div>Inhibition of PKM2 reduces apoptosis induced by blue light exposure in 661W cells. (a, b) Dose-dependent effects of shikonin on apoptosis, determined by calcein-AM/PI double staining, of 661W cells at 48 h after light exposure. (c, d) Western blotting showing the effects of shikonin on BCL2 and BAX expression levels in 661W cells after light exposure.
