Abstract

Purpose MLN4924 is a second-generation inhibitor that targets ubiquitin–proteasome system by inhibiting neddylation activation enzyme (NAE), and subsequently blocking the neddylation-dependent activation of Cullin-RING E3 ligases (CRLs), which leads to the accumulation of CRLs substrates and hence, suppressing diverse tumor development. In this study, we investigated the potential application of this first-in-class inhibitor MLN4924 in the treatment of human renal cell carcinoma both in vitro and in vivo. Methods The impact of MLN4924 on renal cancer cells was determined by measuring viability (MTS), proliferation cell count test and clonogenic assays, cell cycle progression (flow cytometry with propidium iodide staining), apoptosis (flow cytometry with annexin V-FITC labeling) and DNA damage (immunofluorescent staining). The cell cycle regulatory mol- ecules, apoptosis-related molecules, and cell stress-related proteins were examined by Western blotting. The influence of tumor cell migration was analyzed by wound healing assays. A well-established SCID xenograft mouse model was used to evaluate the effects of MLN4924 on tumor growth in vivo. Results The data showed that MLN4924 induced a dose-dependent cytotoxicity, anti-proliferation, anti-migration, and apop- tosis in human renal cancer cells; and caused cell cycle arrested at the G2 phase.
