In mice with chemically induced colitis, phytic acid supplementation is linked to lower severity of symptoms, such as less weight loss and shorter colon shortening.
Mechanism
Synthesis from 1 study
Phytic acid stops a harmful signal in gut cells that normally causes swelling and breaks down the protective lining. When this signal is blocked, the gut stays sealed and calm, preventing bacteria from triggering more damage. This keeps the colon healthy and helps the body maintain its weight.
Most probable mechanism
Phytic acid enters intestinal cells and blocks a key signaling pathway that normally triggers inflammation. This blockage prevents the activation of proteins that turn on genes for inflammatory chemicals, which reduces swelling and damage in the gut. At the same time, the barrier between cells in the gut lining stays strong, with more proteins holding the cells together and more protective mucus being made. This keeps harmful bacteria from leaking into the tissue, which stops the immune system from overreacting, leading to less weight loss and shorter colon damage.
Phytic acid enters intestinal epithelial cells and interacts with intracellular signaling components to inhibit AKT phosphorylation
Inhibition of AKT reduces activation of the IKK complex, preventing degradation of IκBα
Stabilized IκBα retains NF-κB p65 in the cytoplasm, blocking its nuclear translocation
Reduced nuclear NF-κB p65 decreases transcription of pro-inflammatory cytokines including IL-1β, IL-6, and TNF-α
Suppressed inflammation preserves expression of tight junction proteins (occludin, claudin-3, ZO-1) and mucin-2 in the intestinal epithelium
Intact tight junctions and mucus layer prevent bacterial translocation and subsequent immune activation in the lamina propria
Reduced immune activation and tissue damage lead to preservation of colon length and mitigation of weight loss
