ABSTRACT
Objective:To explore the effects of apigenin on apoptosis and hypoxia inducible factor-1α (HIF-1α)/nuclear factor κB (NF-κB) signaling pathway in renal cancer A498 cells.Methods:Human renal cell carcinoma A498 cells were cultured in vitro and divided into different concentrations of apigenin (10, 20, 40 μmol/L) groups, apigenin (40 μmol/L)+ HIF-1α agonist dimethylenediaminoacetic acid (DMOG) group, HIF-1α inhibitor rifiximab (YC-1) group, and control group. Cell proliferation was detected using cell counting kit-8 (CCK-8) assay and plate clone formation assay, apoptosis was detected using Hoechst 33258 staining and flow cytometry, and expression of apoptotic proteins and HIF-1/NF-B pathway proteins was detected using Western blot assay.Results:Celery extract significantly inhibited the proliferation of A498 cells, and the inhibitory effect was concentration dependent ( P<0.001). Compared with the control group, the apoptosis rates of A498 cells in the 10, 20, and 40 μmol/L apigenin groups and YC-1 groups were significantly increased [(4.35±1.04)% vs (10.06±1.13)%, (18.52±2.58)%, (32.17±2.63)%, (26.94±2.41)%], as well as the expression levels of B lymphocyte tumor 2 related protein (Bax) and Cleaved Caspase-3 protein, while the expression levels of B lymphocyte tumor 2 (Bcl-2) were significantly reduced (all P<0.001). Compared with the control group, the HIF-1α protein expression levels (0.85±0.08 vs 0.63±0.06, 0.31±0.03, 0.16±0.02) and p-NF-κB p65/NF-κB p65 ratio (0.82±0.08 vs 0.51±0.05, 0.30±0.03, 0.13±0.01) of A498 cells in the 10, 20, and 40 μmol/L apigenin groups were significantly reduced (all P<0.001). Compared with the apigenin group, the apoptosis rate of A498 cells in the apigenin+ DMOG group was significantly reduced [(32.17±2.63)% vs (14.85±1.62)%], and the expression levels of Bax and Cleared Caspase-3 proteins were significantly reduced, while the expression levels of Bcl-2 proteins were significantly increased (all P<0.001). Conclusions:Apigenin may promote apoptosis in renal cancer A498 cells by inhibiting the activation of the HIF-1α/NF-κB signaling pathway.
