KEGG enrichment analysis for DEGs and Network plot of DEGs related to melanogenesis. A Three significantly enriched KEGG pathways from the DEGs in the WLS vs CB group. B Three significantly enriched KEGG pathways from the DEGs in the WLS vs CH group. C Four significantly enriched KEGG pathways from the DEGs in the CH vs CB group. D Two pathways including Tyrosine metabolism and Melanogenesis with shared terms in KEGG pathway with DEGs comparing the WLS vs CB and WLS vs CH groups, respectively. E The ECM-receptor interaction was a shared term in the KEGG pathway with DEGs comparing the WLS vs CH and CH vs CB groups, respectively. F Network plot of DEGs related to tyrosine metabolism (DCT, TYRP1, TYR, IL4I1, ADH1C, ADH6 and HPD). G Network plot of DEGs related to the melanogenesis pathway (EDNRB2, CREB3L3, TYRP1, TYR, FZD5, GNAO1, WNT11B and PLCB4)
