OHSU researchers develop gene therapy to prevent inherited diseases such as cancer, diabetes, and neurodegenerative diseases by transferring healthy mitochondria into eggs. The breakthrough could help break the chain of maternally-based diseases passed from generation to generation.
Scientists at Stanford University School of Medicine have devised a new biological marker to monitor mitochondrial disorders, which cause organ failure, seizures, and premature death. The discovery enables researchers to hunt for treatments and helps physicians check patients' status before health crises erupt.
A study published in the American Journal of Human Genetics reveals a significant presence of mitochondrial DNA mutations in the general population. Researchers found that at least 1 in 200 individuals harbor pathogenic mitochondrial DNA mutations, which may lead to diseases such as muscle weakness and diabetes.
