Relative mRNA expression of theaflavin (TF)-targeted genes in A375 cells after 24 h treatment. By means of Fisher’s least significant difference (LSD) multiple comparisons, data (mean ± SD) with same lowercase letter (a vs. a; b vs. b; c vs. c) indicate no significant difference between each other, while data with different letters (a vs. b vs. c vs. d) indicate significant difference with each other.
