Ethanol increases CCL5 expression. (a) Immunohistochemical analysis of CCL5 protein expression in ever alcohol consumption and never alcohol consumption patients tumor tissues (n = 97) (bar: 100 μm). CCL5 indicates brown stain, the former displayed higher levels of CCL5 in both the tumors and the adjacent non-tumor tissues of drinkers. (b) Quantitatinve analysis of CCL5 was determined by mean optical density. (c) Colorectal cancer cells were exposed to alcohol ((200 mg/ml) for indicated time and conditioned medium were collected and assayed for secreted CCL5 by ELISA. Each data point was the mean ± SEM of three independent experiments and presented relative to the control. *P < 0.05, 1, #P > 0.05.
