Abstract:
Objective: To explore the effects of UCP2 inhibitor genipin (GEN) on the proliferation and mitochondrial function of human hypopharyngeal carcinoma FaDu cells. Methods: FaDu cells were treated with different concentrations of GEN for 24 hours and divided into the GEN 0 μmol/L (control) group, the 50 μmol/L group, the 100 μmol/L group, the 200 μmol/L group and the 400 μmol/L group. The CCK-8 method was employed to assess cell proliferation, and the DCFH-DA probe and JC-1 flow cytometry were utilized to measure the impact of GEN on reactive oxygen species (ROS) levels and mitochondrial membrane potential in FaDu cells. Laser confocal microscopy was utilized to observe the effect of GEN on the mitochondrial membrane permeability transition pore (MPTP) in FaDu cells. Spectrophotometry was employed to measure lactate levels in cells, and Western blot analysis was conducted to monitor changes in UCP2 protein expression. Results: In comparison with the control group, GEN significantly inhibited the proliferation activity of FaDu cells (PPPPPPPPConclusion: GEN modulates the expression of UCP2 in cells, consequently altering their redox potential and mitochondrial function, thus inhibiting the viability and inducing apoptosis in human nasopharyngeal carcinoma FaDu cells.
