Antitumor effect of fructose 1,6-bisphosphate and its mechanism in hepatocellular carcinoma cells.

We aimed to investigate the antitumor effect and mechanism of fructose 1,6-bisphosphate (F1,6BP) in a hepatocellular carcinoma cell line. HepG2 cells were treated with different concentrations of F1,6BP alone or in combination with antioxidant N-acetyl-L-cysteine (NAC) or catalase (CAT), and cell proliferation assays were performed. Nuclear morphology was observed by fluorescence microscopy after Hoechst staining, and apoptosis was measured with flow cytometry.
