The effects of NMT1 on cancer development are extensive, especially in colon, lung, breast and ovarian cancers, and involve proto-oncogene tyrosine-protein kinase Src signalling and mechanisms of cellular metabolism (mitochondria, lysosomes), endoplasmic reticulum (ER) stress and lipid recoding (Figure 1). This evidence concerns the gene NMT1 and ovarian carcinoma.
