Potential Key Regulator Detected
The underlying genetic or environmental causes of inflammatory bowel disease remain largely unknown. However, the major problem associated with this chronic condition is that the lining of the gut becomes leaky, allowing material from the lumen of the intestine to pass through this barrier and trigger an inflammatory response.
The intestinal barrier works by maintaining a delicate balance between the proliferation and death of epithelial cells at the surface of the barrier. If the balances tips so that more cells die than grow, as is the case in IBD, the barrier is no longer intact and cannot function properly.
This latest research led by Conway Fellow, Professor Cormac Taylor has shown that in the absence of an oxygen-sensing enzyme, prolyl hydroxylase 1 (PHD1), epithelial cell death is reduced and the intestinal barrier function is enhanced. Therefore, PHD1 may be a useful target for pharmacologic inhibition in IBD.
The findings provide information that may be important in developing a new therapeutic approach to the treatment of the disease.
The team, which includes international propose that by delaying or suppressing epithelial cell death, the gut lining would be given time to heal and the integrity of the intestinal barrier could be restored.
Commenting on the research, Taylor said “Inflammatory bowel disease is a condition in need of new and improved therapeutic options. Our current results indicate that targeting the PHD1 enzyme may represent one such approach.”
