For the six upregulated miRNAs, the top 10 enriched KEGG pathways were related to fatty acid metabolism, calcium signaling pathway, AGE-RAGE signaling pathway in diabetic complications, fatty acid degradation, neurotrophin signaling pathway, renin secretion, transcriptional misregulation in cancer, hepatitis B, cell cycle, and MAPK signaling pathway. Here, BDNF is linked to cancer.
