Gastrointestinal (GI) cancer is a group of cancers, affecting the digestive system, including esophagus, gallbladder & biliary tract, liver, pancreas, stomach, small intestine, bowel, and anus
The digestive system consists of the gastrointestinal tract and other parts of the accessory organs of digestion including the tongue, salivary glands, pancreas, liver, and gallbladder), involved in the function of breaking down food into smaller and smaller components then absorbed before passing them as nutrients and fluids to the body.
Most cases of gastrointestinal cancer start in the cells on the surface of the inner lining tissues, depending on the location of the affected organs.
At the early stage, most patients are asymptomatic due to the small size of the tumor. However, at the later stage, after penetrating into deeper layers of the organ, cancer cells can travel through blood and fluids circulation to infect other healthy tissues or organs, leading to secondary metastasis.
At this stage, besides sharing the general symptoms of other types of cancer, gastrointestinal cancer also cause symptoms of severe pain and bleeding due to the overgrowth tumor size that has suppressed the nearby blood vessels and nerve cells.
The exact causes of gastrointestinal cancer are not identified. However, genetic preposition, unhealthy lifestyle and medical conditions are some of the prevalent risks of the disease.
Some researchers suggested that a poor diet may have a strong implication on the incidence of gastrointestinal cancer.
Dr. Reilly T. Enos, the lead scientist said, "High-fat-diet (HFD) consumption is associated with colon cancer risk".
And, "HFDs with the highest SF content had the greatest concentration of Muc2. Our data suggest that high dietary SF is protective in the AOM/DSS model of colon cancer, which may be due, at least in part, to the ability of SF to maintain intestinal barrier integrity through increased colonic Muc2".
With an aim to find a natural compound for the treatment of gastrointestinal cancers, researchers examined the 3,3'-Diindolylmethane (DIM) activity against effective gastrointestinal cancers.
In vivo and vitro, injection of the DIM acted upon several cellular and molecular processes in gastrointestinal cancer cells.
In cancer cells apoptosis, DIM initiated production reactive oxygen species (ROS) in generating stress, triggering DNA damage by increasing the cytotoxicity.
In angiogenesis, DIM inhibited the protein associated with the generation of a new blood vessel for cell survival and proliferation.
In cell cycle regulation, DIM deactivated the expression of protein kinases which play the critical roles in the cancer cell division.
Furthermore, DIM triggers cellular endoplasmic reticulum (ER) stress and apoptosis within the cancer cells.
In autophagy, DIM inhibited autophagy that leads to cell death.
In metastasis, DIM inhibited the growth of human cancer cells by interfering with multiple signaling pathways, involved restraining invasion, migration, and promoting apoptosis.
Furthermore, DIM used combined with conventional chemo drugs or therapeutic chemicals increased the efficacy of other drugs for the treatment of gastrointestinal cancer.
Taken altogether, 3,3'-Diindolylmethane derived from the digestion of indole-3-carbinol may be considered a supplement for the prevention and treatment of gastrointestinal cancers, pending to the confirmation of the larger sample size and multicenter human study.
Intake of 3,3'-diindolylmethane in form of supplements should be taken with extreme care to prevent overdose acute liver toxicity.
