Low folate intake is associated with colon cancer. We combined a proteomics and biochemical approach to identify proteins and pathways affected by folate deficiency in human colonocytes. Folate differentially altered activity and expression of proteins involved in proliferation [e.g., PCNA], DNA repair [e.g., XRCC5, MSH2], apoptosis [e.g., BAG family chaperone protein, DIABLO and porin], cytoskeletal organization [e.g., actin, ezrin, elfin], and expression of proteins implicated in malignant transformation [COMT, Nit2].
