In addition, both baicalein and baicalin inhibited LDHα expression in Mel586, A375, and B16F0 melanoma cells, and ENO1 expression in SK-MEL-2 and A375 cells, as well as partially suppressed PKM2 expression in SK-MEL-2, A375, and B16F0 tumor cells (Supplementary Figure S2). Here, PKM is linked to melanoma.
