DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Study stresses importance of investigating telomeres to improve diagnoses, develop treatments for many diseases

Studying telomeres, the structures that protect the ends of chromosomes, has become a key issue in biology. In recent years, not only has their relation to ageing been confirmed; defective telomeres seem to be linked to more and more illnesses, including many types of cancer.

New hand-held paper machine could be used for point-of-care detection of infectious diseases, cancer

In the U.S. and other industrialized nations, testing for infectious diseases and cancer often requires expensive equipment and highly trained specialists. In countries where resources are limited, performing the same diagnostics is far more challenging. To address this disparity, scientists are developing a portable, low-cost "paper machine" for point-of-care detection of infectious diseases, genetic conditions and cancer.

Research breakthrough opens door to a world of regenerative medicine for treating mitochondrial disease

A study led by Shoukhrat Mitalipov, Ph.D., and Hong Ma, M.D., Ph.D., at the Center for Embryonic Cell and Gene Therapy at Oregon Health & Science University and the Oregon National Primate Research Center has revealed the first critical step in developing novel gene and stem cell therapy treatments for patients with mitochondrial disease.

Research could lead to new approaches to treating spinal cord and brain injuries

Many an injury will heal, but the damaged spinal cord is notoriously recalcitrant. There's new hope on the horizon, though. A team of researchers led by the University of South Carolina's Jeff Twiss just reported an innate repair mechanism in central nervous system axons that might be harnessed to regenerate nerves after brain or spinal cord injuries.

Single molecule appears to be central regulator driving cancer metastasis

Cancer is a disease of cell growth, but most tumors only become lethal once they metastasize or spread from their first location to sites throughout the body. For the first time, researchers at Thomas Jefferson University in Philadelphia report a single molecule that appears to be the central regulator driving metastasis in prostate cancer.
