Gossypol 0-8 MDM2 proto-oncogene Homo sapiens 51-55 28274247-4 2017 Because MDM2 is an RNA-binding protein and its targets include VEGF mRNA, we investigated whether gossypol has an inhibitory effect on MDM2-VEGF. Gossypol 98-106 MDM2 proto-oncogene Homo sapiens 135-144 28274247-5 2017 METHODS: UV cross-linking and RNA binding assay, isothermal titration calorimetry assay, and ubiquitination assay were performed to determine mechanisms by which gossypol functions as a dual inhibitor of MDM2 and VEGF. Gossypol 162-170 MDM2 proto-oncogene Homo sapiens 204-208 28274247-6 2017 The effect of gossypol on MDM2 and VEGF expression, cancer cell apoptosis, tumor growth and VEGF-mediated angiogenesis were studied in vitro and in vivo in different human breast cancer models with a different p53 status. Gossypol 14-22 MDM2 proto-oncogene Homo sapiens 26-30 28274247-7 2017 RESULTS: We observed that gossypol inhibited expression of both MDM2 and VEGF in human breast cancer cells with either wild-type or mutant p53. Gossypol 26-34 MDM2 proto-oncogene Homo sapiens 64-68 28274247-8 2017 A nechanistic study further demonstrated that, through disrupting the interaction between MDM2 protein and VEGF mRNA, gossypol induced MDM2 self-ubiquitination and decreased VEGF translation simultaneously, which resulted in both apoptosis and anti-angiogenesis effects. Gossypol 118-126 MDM2 proto-oncogene Homo sapiens 90-94 28274247-11 2017 CONCLUSION: Gossypol has anti-cancer effects by dual-targeting MDM2 and VEGF in human breast cancer.
