Figure 4From: Antimelanogenic effect of c-phycocyanin through modulation of tyrosinase expression by upregulation of ERK and downregulation of p38 MAPK signaling pathwaysThe down-regulative effect of Cpc on p38 MAPK and CREB signaling pathways. Cells were treated with Cpc (0.1 mg/mL). Immunoblot analysis was performed at assigned intervals for (A) CREB, and (B) p38 MAPK (control (black); CPC-treated (grey)).Back to article page
