Abstract
AIM: To observe the effects of Quercetin on the invasion of human esophageal cancer cells, and to investigate the possible mechanism.
METHODS: Human esophageal cancer cell line EC109 was treated with different concentrations of Quercetin, and then the anchorage independence growth of EC109 cells was studied by colony formation in soft agar; the invasion ability of EC109 cells was determined by Boyden chamber, and the expression levels of midkine mRNA and protein were detected by real time RT-PCR and Western blot assay, respectively.
RESULTS: After Quercetin treatment, the malignant proliferation and invasive ability of EC109 cells were obviously decreased, which showed a dose-dependent manner (all P < 0.05). Meanwhile, Quercetin down-regulated the expression of midkine mRNA and protein in a dose- and time-dependent manner (all P < 0.05).
CONCLUSION: Quercetin can inhibit the invasion of EC109 cells by down-regulating midkine expression.
