ACSL4
ACSL4: A Fatty Acid Transporter with Roles in Metabolism, Disease, and Research
Description
ACSL4, also known as acyl-CoA synthetase long-chain family member 4, is an enzyme responsible for activating long-chain fatty acids, a crucial step in fatty acid metabolism. It converts these fatty acids into acyl-CoA derivatives, enabling their entry into various metabolic pathways, including energy production, signaling, and lipid synthesis. ACSL4 plays a central role in cellular lipid handling and contributes to overall energy homeostasis.
Associated Diseases
Dysregulation of ACSL4 has been implicated in several human diseases, including:
- Metabolic disorders: ACSL4 deficiency can lead to impaired fatty acid utilization and energy production, resulting in conditions such as fatty acid oxidation disorders and cardiomyopathy.
- Cardiovascular disease: Studies suggest that ACSL4 contributes to the formation of atherosclerotic plaques, promoting the development of heart disease.
- Cancer: Increased ACSL4 expression has been associated with enhanced fatty acid uptake and metabolism in cancer cells, supporting tumor growth and progression.
Did you Know ?
According to research published in the journal "Nature Metabolism," ACSL4 is overexpressed in over 50% of breast cancer cases, highlighting its potential contribution to cancer development.
