Genetic analysis rewrites salamander's evolutionary history

...ose needed to produce energy for the cell. They're inherited without recombination from the mother, and therefore represent an unbroken female chain going back perhaps 100-150 million years in plethodontid salamanders. By looking at mutations in the mitochondrial DNA, biologists can infer the pattern of evolut...

Disruption of protein-folding causes neurodegeneration, mental retardation

...angliosidosis is a lysosomal storage disorders, an inherited disease in which one or more enzymes in the lysosomes are defective. Lysosomes are the cell's recycling centers, where proteins, fats and other molecules are broken down into their basic building blocks, which are then reused to make new molecules. L...

New clues to hereditary blinding disease found

HANOVER, NH Seeking a cure for an inherited disease that causes blindness in over one million people worldwide, Dartmouth Medical School researchers have discovered a critical role for zinc in retinitis pigmentosa. The amount of zinc, a trace metal naturally absorbed by the body, can determine...

Retroviral gene therapy? ASLV, HIV, and MLV show distinct target site preferences

Many diseases (including inherited disorders like cystic fibrosis to cancer) have a genetic component and gene therapy holds the promise of restoring compromised genes with their healthy counterparts. That promise was quashed when a teenager -- Jesse Gelsinger -- suffering from a rare...

Scientists suggest framework for epigenetics in common disease
