UVB-Induced Secretion of IL-1β Promotes Melanogenesis by Upregulating TYR/TRP-1 Expression In Vitro

Figure 5

Expression levels of SCF and COX-2 mRNA after IL-1β treatment. After HaCaT cells were cultured with 4 pg/μl IL-1β for 24 hours, RT-qPCR was used to measure expression levels of SCF and COX-2 mRNA. (a) Expression levels of SCF. (b) Expression levels of COX-2. for all groups. .
