Effect of TGT on expression of pro-inflammatory cytokines in LPS stimulated HaCaT cells. a LPS-stimulated HaCaT cells were treated with or without different doses of TGT for 24 h. Cytokine mRNA levels were measured by RT-PCR. b The density of each band was calculated with image processing program, Image J, and represented as bar graph. *; compared to control. #; compared to stimulated cells. Control; HaCaT with LPS (−), Stimulation; HaCaT with LPS (+)
