We’ve found so far that people with inflammatory bowel disease tend to have lower levels of a protein called IPMK in their intestinal tissue, and this is connected to less active HDAC3 and increased gut lining leakage [1]. The evidence we’ve reviewed includes eight supporting assertions and no refuting ones, which leans toward a link between reduced IPMK, impaired HDAC3 function, and gut barrier issues in this condition. IPMK helps regulate cellular signals, and HDAC3 is involved in controlling gene activity that maintains the gut’s protective barrier. When IPMK is lower, HDAC3 doesn’t work as well, which may make the gut lining more porous — allowing substances to pass through that normally shouldn’t. This doesn’t mean low IPMK causes the disease, but it suggests it could be part of how the gut becomes more vulnerable. We don’t yet know if this is a result of inflammation or if it contributes to starting it. The evidence is limited to one type of observation — tissue protein levels — and doesn’t include data from animal models, interventions, or long-term outcomes. More research would be needed to understand whether restoring IPMK or HDAC3 activity changes disease progression. For now, this pattern is consistent across the studies we’ve reviewed, but it remains one piece of a larger puzzle. If you have inflammatory bowel disease, this doesn’t change current treatment advice, but it highlights an area science is still exploring to better understand gut health.
