Inhibitory effect of combined A. lakoocha and G. glabra extracts on proteins related to melanogenesis. (a) Protein bands for microphthalmia-associated transcription factor (MITF), tyrosinase (TYR), tyrosinase-related protein (TRP)-1, TRP-2 and β-actin. (b) Relative intensity of protein levels of MITF, TYR, TRP-1, and TRP-2. Cells were treated with mixtures of Al95 and Gg95 at final concentration of 0.1 mg/mL at ratios of 1:1 and 9:1 for 48 h. The samples derive from the same experiment and blots were processed in parallel. The data are means ± SD from three independent experiments. The superscript letters (*) indicate significant difference at p < 0.01.
