CAMP and cancer: We observed a depletion of three biological pathways, including beta − Lactam resistance, cationic antimicrobial peptide (CAMP) resistance and viral proteins functions, and an up-regulation of 10 biological pathways, including nitrogen and methane metabolism, microRNAs in cancer and tropane, piperidine and pyridine alkaloid biosynthesis in CAD patients comparing with health controls (P < 0.05, Fig. 3a and Supplementary Table S4).
