Effect of ginkgetin on proliferation of human cervical cancer (HeLa) cells and the underlying mechanism were investigated. Human cervical cancer (HeLa) cells were cultured at 37 °C in 10 % fetal bovine serum (FBS) supplemented RPMI 1640 medium in a humidified incubator containing 5 % CO2. Cell proliferation was determined using MTT assay, while real-time quantitative polymerase chain reaction (qRT-PCR) and enzyme-linked immunosorbent assay (ELISA) were used to determine the levels of expression of interleukin 1β (IL-1β), tumor necrosis factor-α (TNF-α) and interleukin 8 (IL-8). The expressions of p38 mitogen-activated protein kinases (p38 MAPK) and nuclear factor kappa-light-chain-enhancer of activated B cells (NF- κB) were determined using Western blotting. Treatment of HeLa cells with ginkgetin significantly and time- and dose-dependently inhibited their proliferation (p 0.05). The results of qRT-PCR and ELISA showed that the levels of expression of TNF-α, IL-1β and IL-8 mRNAs were significantly and dose-dependently reduced in HeLa cells after 48 h of treatment with ginkgetin, when compared with the control group (p < 0.05). The anti-proliferative effect of ginkgetin on HeLa cells is exerted via a mechanism involving the p38/NF-κB pathway.
