Heme Oxygenase-1 in Gastrointestinal Tract Health and Disease Puentes Pardo, José David Moreno SanJuan, Sara Carazo, Ángel León, Josefa Heme oxygenase Gastrointestinal tract Cancer Diabetes Pancreatitis Inflammatory bowel disease Peptic ulcer disease Fatty liver disease Ferroptosis Heme oxygenase 1 (HO-1) is the rate-limiting enzyme of heme oxidative degradation, generating carbon monoxide (CO), free iron, and biliverdin. HO-1, a stress inducible enzyme, is considered as an anti-oxidative and cytoprotective agent. As many studies suggest, HO-1 is highly expressed in the gastrointestinal tract where it is involved in the response to inflammatory processes, which may lead to several diseases such as pancreatitis, diabetes, fatty liver disease, inflammatory bowel disease, and cancer. In this review, we highlight the pivotal role of HO-1 and its downstream e ectors in the development of disorders and their beneficial e ects on the maintenance of the gastrointestinal tract health. We also examine clinical trials involving the therapeutic targets derived from HO-1 system for the most common diseases of the digestive system. 2021-02-11T10:39:41Z 2021-02-11T10:39:41Z 2020-12-02 info:eu-repo/semantics/article Puentes-Pardo, J.
