VEGFA and basal cell carcinoma: In BP, upregulated DEGs were obviously abundant in the carbohydrate catabolic process, carbohydrate derivative catabolic process, negative regulation of the fatty acid biosynthetic process, regulation of the cholesterol metabolic process, negative regulation of the fatty acid metabolic process, etc. In the KEGG pathway, the upregulated DEGs obviously enriched six pathways, namely, the PPAR signaling pathway, the VEGF signaling pathway, linoleic acid metabolism, signaling pathways regulating pluripotency of stem cells, basal cell carcinoma, and phagosome.
