Abstract: Gastrointestinal (GI) cancers are one of the most common human malignancies
and a leading cause of morbidity and mortality worldwide. One of the most prominent
hallmarks of cancer and a basic trait of almost all GI malignancies is genomic/epigenomics
alterations. DNA methylation is highlighted as a fundamental mechanism underlying
the inactivation of several tumor-suppressor gene signaling pathways. Thus, sites
of DNA methylation can be triggered for cancer therapy. Available therapeutic procedures
for GI cancer show unsatisfactory efficacy, and some treatments are associated
with severe side effects, including ulceration or bleeding. Therefore, it is essential to find
alternative treatments. There is growing evidence indicating that some chemopreventive
phytochemicals can combat cancer. One of the most systematically investigated nutraceuticals
for its advantages in managing different diseases is curcumin (CUR). CUR is well
known for its potent anticancer characteristics by targeting epigenetic mechanisms, with
DNA methylation at the forefront. Prior investigations have indicated that CUR treatment
can benefit GI cancers by controlling several signaling pathways related to oxidative
stress and epigenomics pathways. The present literature displays recent evidence regarding
DNA methylation alterations by CUR and its potential role in GI cancer prevention
and treatment.
