New Enzyme Found to Help Prevent Fatty Liver Disease

Topic: Health

Researchers at Cedars-Sinai Health Sciences University discovered an enzyme called UBE2N that may help protect the liver from damage caused by fatty liver disease. They found that levels of this enzyme decline as the disease becomes more advanced, and restoring it reduced liver damage in mice.

Fatty liver disease is a common condition where excess fat builds up in the liver. It affects an estimated 100 million people in the U.S. alone. In some cases, fatty liver disease can progress to a more serious form called metabolic dysfunction-associated steatohepatitis (MASH). This condition causes inflammation and scarring in the liver, making it difficult to treat.

Researchers at Cedars-Sinai Health Sciences University were studying MASH when they discovered that levels of an enzyme called UBE2N decline as the disease becomes more advanced. They found that this enzyme helps remove damaged mitochondria from the liver cells and supports the breakdown of fat. When levels of UBE2N fell, the researchers saw more damage to the liver.

To test their findings, the researchers restored UBE2N to normal levels in the livers of laboratory mice. After doing so, they observed reductions in fat accumulation, inflammation, and scarring. These results suggest that UBE2N could become a potential treatment target for preventing fatty liver disease from advancing to MASH.

Why It Matters

This discovery is important because fatty liver disease affects millions of people worldwide, including many Indians. It can lead to serious health problems if left untreated. If researchers can develop treatments that target UBE2N, it could help prevent the progression of fatty liver disease and improve the lives of those affected.

Key Facts

• Fatty liver disease affects an estimated 100 million people in the U.S. alone.
• Metabolic dysfunction-associated steatohepatitis (MASH) is a more serious form of fatty liver disease that causes inflammation and scarring in the liver.
• UBE2N is an enzyme that helps remove damaged mitochondria from the liver cells and supports the breakdown of fat.
• Restoring UBE2N to normal levels reduced liver damage in mice.
• Researchers believe that targeting UBE2N could lead to new treatments for preventing fatty liver disease from advancing to MASH.
