Genetic point mutation linked to non-alcoholic fatty liver disease

Non-alcoholic fatty liver disease (NAFLD) is a metabolic condition that has a high global prevalence and is rapidly growing. Researchers discovered that albino mice with a mutant tyrosinase gene are more susceptible to the inflammatory liver disease, non-alcoholic steatohepatitis. The buildup of fat in the liver, unrelated to alcohol misuse or other liver illnesses, is known as non-alcoholic fatty liver disease (NAFLD). NAFLD is frequently linked to obesity and diabetes, and it’s considered a symptom of metabolic syndrome. With…

Neurodegeneration in Parkinson’s disease can be slowed by inhibition of Bach1 protein

Researchers have found that the suppression of Bach1 protein, a known transcriptional repressor of the Nrf2 pathway, slows the deterioration of neurons in Parkinson’s diseased brains. Parkinson’s disease (PD) is the one of the most frequently diagnosed neurodegenerative conditions, affecting over 10 million individuals globally and over a million people in the United States. While there is no cure for Parkinson’s disease, current treatments focus on treating motor symptoms rather than the underlying brain damage. Researchers from the Medical…

University of Cambridge researchers find Alzheimer’s disease progresses much differently than previously thought

According to the new study, the replication of aggregates in distinct areas of the brain, rather than the dissemination of aggregates, is the mechanism that controls the rate of advancement in Alzheimer’s disease. This is the first study to use human data to figure out which pathways affect Alzheimer’s disease development over time. (Image: GerryShaw/Wikimedia Commons) Researchers have utilized human data for the first time to measure the pace of key processes that contribute to Alzheimer’s disease, and they…
