LEP and cancer: In the KEGG pathway analysis, DElncRNAs were related to the CCL18 signaling pathway, ncRNAs involved in STAT3 signaling in hepatocellular carcinoma, lncRNA mediated mechanisms of therapeutic resistance (Figure 2(b)), DEmiRNAs were related to the integrated breast cancer pathway, the TGF-beta signaling pathway, senescence, and autophagy in cancer (Figure 2(d)), and DEmRNAs were related to the ectoderm differentiation, the leptin signaling pathway, and so on (Figure 2(f)).
