HEATR2
Heatr2 Gene: Unraveling Its Significance in Cardiovascular Health
Description
The heatr2 gene encodes a G protein-coupled receptor known as the Hydroxycarboxylic Acid Receptor 2 (HCAR2). It is primarily expressed in the endothelial cells of the vascular system and plays a crucial role in the regulation of vascular function. HCAR2 responds to specific ligands, including medium-chain fatty acids and hydroxycarboxylic acids, and subsequently activates intracellular signaling pathways.
Associated Diseases
Dysregulation of HCAR2 has been implicated in the development of several cardiovascular diseases:
- Hypertension: Studies have shown that individuals with reduced HCAR2 expression or impaired signaling exhibit elevated blood pressure.
- Atherosclerosis: HCAR2 deficiency has been linked to increased plaque formation in the arteries, increasing the risk of heart attack and stroke.
- Cardiac fibrosis: Overactivation of HCAR2 can lead to excessive collagen deposition in the heart, resulting in cardiac fibrosis and impaired heart function.
Did you Know ?
Research has revealed that a common genetic variant in the heatr2 gene is associated with a 15% increased risk of developing hypertension. This highlights the significant role of HCAR2 in maintaining blood pressure homeostasis.
