The DEGs of KEGG pathway enrichment analysis data showed that the top ten KEGG pathways enriched were renal cell carcinoma, arrhythmogenic right ventricular cardiomyopathy (ARVC), base excision repair, cell cycle, chronic myeloid leukemia, neurotrophin signaling pathway, pancreatic cancer, pathways in cancer, progesterone-mediated oocyte maturation, and regulation of actin cytoskeleton (Table 2) (Figure 3(b)). Here, BDNF is linked to renal cell carcinoma.
