Abstract
The present study evaluated the cytotoxic activity of methyl jasmonate (MJ) in endometrial cancer cells and examined the hypothesis that the apoptotic and anti-proliferative actions of MJ in these cell lines can be enhanced by co-targeting the insulin-like growth factor-1 receptor (IGF1R) signaling pathway. MJ had a potent pro-apoptotic effect and exhibited significant toxicity in all cell lines tested. MJ in combination with NVP-AEW541, a selective IGF1R tyrosine kinase inhibitor, had significantly increased cytotoxicity. MJ decreased IGF1R phosphorylation, however, it enhanced AKT phosphorylation and abolished the anti-apoptotic effect of IGF1. These findings suggest that combined IGF1R inhibitor and MJ administration may constitute an attractive modality for treating endometrial cancer.
