Abstract

Hypoxia plays critical roles in the pathobiology of heart disease, cancer, stroke, eye, and chronic lung disease, which are responsible for 60% of deaths in the United States. Hypoxia-mediated activation of the hypoxia-inducible-factor (HIF) pathway, leading to transcriptional changes in gene expressions, plays a fundamental role in the pathobiology of above diseases. Yet, molecular and biochemical mechanisms governing this fundamental pathway remain poorly understood. Since our initial identification of first iron(II), 2-oxoglutarate (2OG)-dependent dioxygenase involved in transcription regulation by the HIF pathway, results from numerous studies have established a key role for these enzymes in epigenetic transcriptional regulation. Our long term goal is to use our experience in the HIF pathway and dioxygenases/demethylases to delineate their roles in normal development/ disease states, and identify small molecule modulators that can be used to develop more effective strategies for therapeutic intervention. We have recently shown that hypoxia induces the expression of a number of histone lysine demethylases/ dioxygenases (KDMs) in cancer and retinal pigment epithelial cells. Moreover, we found that the expression of pro-angiogenic genes (ADM and GDF15) is dependent on KDMs under hypoxic conditions. Further, treating the cells with a general KDM inhibitor blocks the expression of these pro-angiogenic genes. Results from our studies suggest that specific inhibitors of KDMs such as JMJD1A can be a new therapeutic approach to treat diseases caused by the hypoxia
