Effect of quercetin on the expressions of metastasis-related protein with Western blot assay. (a) Western blot for the expressions of E-cadherin, mitochondrial membrane potential-2 and mitochondrial membrane potential-9 in Caco-2 cells. (b) E-cadherin protein level; (c) mitochondrial membrane potential-2 protein level. (d) Mitochondrial membrane potential-9 protein level. Data were expressed as the means ± standard deviation (n = 3). *P < 0.05, **P < 0.01 versus control blank group
