Fig. 7From: Flavokawain B targets protein neddylation for enhancing the anti-prostate cancer effect of Bortezomib via Skp2 degradationFKB selectively inhibits the growth of RB deficient cells compared to RB wild type cells. a, mRNA expression of Rb and Skp2 was analyzed via RT-PCR and qPCR in MEF wild-type and Rb−/− cell lines. b, Mouse embryonic fibroblasts (MEFs) and c, mouse prostate epithelial cells (MPECs), wild-type and Rb−/−, were treated with 0.1% DMSO or indicated concentration of FKB for 72 h. Cell viabilities were measured via MTT assaysBack to article page
