Evaluation of the expression of TYR reporter in vitro.
(A) Western blot assay of tyrosinase expression in 231-TYR+Dox, 231-TYR and 231 cells. GAPDH was used as the control. (B) Time-response tyrosinase activity curves in three groups. (C) Photos of the cell pellets from 231-TYR + Dox, 231-TYR and 231 cells. (D) Masson-Fontana silver staining in 231-TYR + Dox, 231-TYR and 231 cells.
