TBK1 inhibitor amlexanox exerts anti-cancer effects against endometrial cancer by regulating AKT/NF-κB signaling
Endometrial cancer, a common gynecological malignancy, poses significant clinical challenges, particularly in advanced or recurrent cases. TANK-binding kinase 1 (TBK1), a serine/threonine kinase, plays crucial roles in inflammation and immunity by activating nuclear factor (NF)-κB and interferon regulatory factor 3. However, its specific roles in endometrial cancer remain unknown. In this study, we aimed to investigate the anti-cancer effects and underlying mechanisms of amlexanox, a TBK1 inhibitor, against endometrial cancer. The main genetic mutations in TBK1 were found to be mRNA downregulation and missense mutations. Kaplan-Meier plotter analysis revealed that low TBK1 expression was associated with a good prognosis in patients with uterine corpus endometrial carcinoma (UCEC).
