“Moreover, emodin enhanced melanin synthesis by increasing the expression level of tyrosinase (TYR), tyrosine related protein (TRP)-1, TRP-2 , MITF and SIRT1 proteins in live cells treated with H2O2 compared with H2O2 treatment group in the analyses of western blot and immunofluorescence.”
“Thus, emodin promoted melanin synthesis by increasing the expression of TRP-1, TRP-2 , tyrosinase through the activation of MITF transcription factor.”
