This scientific report identifies the transcription factor NRF1 as a critical defender against metabolic dysfunction-associated steatohepatitis (MASH). Researchers discovered that NRF1 levels are significantly depleted in patients and mice with liver disease, leading to a failure in clearing damaged proteins and an increase in ER stress. The study demonstrates that docosahexaenoic acid (DHA), an omega-3 fatty acid, effectively stabilizes NRF1 by preventing its degradation at the cellular membrane. By maintaining NRF1 levels, DHA promotes proteasome activity, which reduces oxidative damage and…
