Of the total 14 miRNAs targeting either NMT1/2 genes or MetAP gene, 13 miRNAs (miR-29a-5p, miR-132-5p, miR-134-5p, miR-137, miR-139-3p, miR-140-5p, miR-199a-3p, mir-520d-5p, miR-548p, miR-943, miR-4317 and miR-628-3p) have been found to have roles in viral infections and 4 miRNAs (miR-127-3p, miR-140-5p and miR-199a-3p and miR-4317) have been implicated in bacterial infections. This evidence concerns the gene NMT1 and viral infectious disease.
