Apoptosis induction and AKT/NF-κB inactivation are associated with regroafenib-inhibited tumor progression in non-small cell lung cancer in vitro and in vivo. Biomed Pharmacother. 2019 Jun 01;116:109032 Authors: Weng MC, Li MH, Chung JG, Liu YC, Wu JY, Hsu FT, Wang HE Abstract Non-small cell lung cancer (NSCLC) is a malignant lung cancer type with poor prognosis. NF-κB, the oncogenic transcription factor, has been recognized as an important mediator in progression of NSCLC. Regorafenib, a multikinase inhibitor, was demonstrated to inhibit tumor progression through suppression of ERK/NF-κB signaling in hepatocellular carcinoma cells in vitro and in vivo. However, whether regorafenib inhibit progression of NSCLC is ambiguous. Thus, the major purpose of present study was to evaluate anticancer efficacy and underlying mechanism of regorafenib on tumor progression in NSCLC in vitro and in vivo. CL-1-5-F4 cells were treated with regorafenib, NF-κB (QNZ) or AKT (LY294002) inhibitor for 24 or 48 h. Then, we performed cell viability assay, NF-κB reporter gene assay, transwell invasion assay and apoptosis related flow cytometry assay on cellular level to verify anti-cancer effect and mechanism of regorafenib. CL-1-5-F4 bearing animal model was treated with vehicle or regorafenib for 28 days. The therapeutic efficacy and mechanism of regorafenib in CL-1-5-F4 bearing animal model were investigated by tumor size evaluation, whole body comp...
