The comet assay revealed severe DNA damage (Tail DNA, fold change, untreated cell; 1, CUR-20 µM; 1.2, KAN-20 µM; 3, and COMB; 4.6) in the A549 cells, while MMP analysis (color change from red to green) and apoptotic staining confirmed cell death morphologically (color change from green to orange). Moreover, Western blot analysis demonstrated that the combination markedly enhanced apoptosis in the A549 cells.
PFKFB3 can enhance ATC cell proliferation and migration via the WNT/β-catenin signaling pathway and plays a crucial role in the regulation of aerobic glycolysis in ATC cells.
KAN0438757 showed a clear antiproliferative effect in rectal cancer cells and PDX without being overly toxic in vivo. It showed promis- ing synergistic efficacy when used in combination with chemotherapy and therefore should be further tested in vivo.
