GHRH and central nervous system cancer: The KEGG pathway enrichment analysis revealed that at 4 h stimulus, upregulated microRNAs were regulating glioma, chronic myeloid leukemia, and TGF-β signaling pathway in MTcES (Figure 6(a)); ubiquitin-mediated proteolysis, p53, and GhRH signaling pathway in MTcES+LPS (Figure 6(b)); and prostate cancer, steroid biosynthesis, and FoxO signaling pathway in MLPS (Figure 6(c)).
