Abstract
Inhibition of protein neddylation pathway has emerged an attractive anticancer strategy in preclinical studies by using Nedd8-activating enzyme (NAE) inhibitor MLN4924 (Pevonedistat). Previous studies have reported the antitumor activity of MLN4924 mediated by its efficacy on apoptosis, autophagy and senescence. However, whether MLN4924 has any effect on renal carcinoma cells (RCC) remains unexplored. Here we reported that MLN4924 specifically inhibited protein neddylation pathway, leading to statistically significantly suppress the proliferation, survival and migration of RCC cells by inducing G2 cell-cycle arrest, followed by apoptosis in a MLN4924 dose-dependent manner. Further mechanistic study revealed that MLN4924-induced apoptosis was mediated by substantial up-regulation of pro-apoptotic NOXA. These findings highlighted the anticancer effects of the neddylation inhibitors (e.g. MLN4924) for the treatment of RCC.
