How it works

When IPMK is low, a crucial brake on destructive enzymes doesn't work, so those enzymes get made too much. These enzymes then break apart the seals between gut cells, letting things leak through that shouldn't. This exact chain of events is seen in both patients and animal models with gut...

Most probable mechanism

In Simple Terms

When a key protein called IPMK is missing, it stops making a molecule that turns on another protein called HDAC3. Without HDAC3 working properly, a specific part of the DNA that controls destructive enzymes stays too loose, causing those enzymes to be made in large amounts. These enzymes then break down the glue that holds gut cells together, letting harmful substances leak through the gut wall.

Causal chain

IPMK binds to HDAC3 on chromatin and synthesizes inositol hexakisphosphate (InsP6)

Verified by multiple studies

which leads to

InsP6 directly binds to HDAC3 and recruits the DAD domain of the NCoR1/2 corepressor complex, activating HDAC3's deacetylase function

Verified by multiple studies

which leads to

Activated HDAC3 removes acetyl groups from histone H4 at lysine 16 at the promoter regions of MMP genes

Verified by multiple studies

which leads to

Loss of HDAC3 activity leads to accumulation of acetylated H4K16 at MMP gene promoters, enabling transcriptional activation

Verified by multiple studies

which leads to

MMP3 and MMP13 are overexpressed and secreted as active proteases

Verified by multiple studies

which leads to

MMP3 and MMP13 degrade tight junction proteins including ZO-1 and occludin

Verified by multiple studies

which leads to

Degradation of tight junction proteins increases paracellular permeability, compromising intestinal barrier integrity

Verified by multiple studies

Similar Assertions

In individuals with inflammatory bowel disease, specific proteins and chemical modifications in intestinal tissue are altered in a pattern that matches changes seen in mice genetically engineered to lack the IPMK protein.

93%

In people with inflammatory bowel disease, specific proteins and enzymes in colon tissue are found at lower levels, while other molecular markers associated with tissue remodeling are higher, similar to patterns seen in mice genetically engineered to lack IPMK.

93%

People with inflammatory bowel disease have lower levels of a protein called IPMK in their intestinal tissue, which is linked to reduced activity of another protein called HDAC3 and greater leakage in the gut lining.

80%

In mouse intestinal cells, removing the IPMK gene lowers a specific molecule called InsP6, which interferes with a protein complex that controls gene activity. This causes changes in gene expression that lead to the breakdown of proteins holding intestinal cells together, resulting in increased leakage through the intestinal barrier.

77%

When the IPMK gene is disabled in gut lining cells of mice, it leads to lower levels of a specific molecule (InsP6), reduced activity of an enzyme (HDAC3), and changes in gene regulation that increase the production of enzymes that break down structural barriers. This results in a leakier intestinal barrier.
