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).

DNA rearrangements in roundworm chromosomes offer insight into genome duplications in developing tumors

A study of DNA rearrangements in roundworm chromosomes may offer new insight into large-scale genome duplications that occur in developing tumors.

Scientists discover special mechanism that delays ageing

Animals that reproduce asexually by somatic cloning have special mechanisms that delay ageing provide exceptionally good health. Scientists at the University of Gothenburg have shown how colony-forming ascidians can activate the enzyme telomerase, which protects DNA. This enzyme is more active also in humans who attain an advanced age.

Worm protein controls key aspects of secretion of growth factors out of cells

Research in the worm is shedding light on a protein associated with a number of different human cancers, and may point to a highly targeted way to treat them.

Unanticipated structure at chromosome ends could be key ingredient in biological 'elixir of life'

In stark contrast to normal cells, which only divide a finite number of times before they enter into a permanent state of growth arrest or simply die, cancer cells never cease to proliferate. Now, scientists at the Salk Institute for Biological Studies have uncovered an important clue to one of the mechanisms underlying cancer cell immortality.

Scientists decode entire genome of lyre-leaved rock cress

It would appear reasonable to assume that two closely related plant species would have similar genetic blueprints. However, scientists from the Max Planck Institute for Developmental Biology in T-bingen, working in cooperation with an international research team have now decoded, for the first time, the entire genome of the lyre-leaved rock cress (Arabidopsis lyrata), a close relative of the thale cress (Arabidopsis thaliana), the model plant used by geneticists.

Nature solves complex topological puzzles in DNA substrate recognition with elegant simplicity

A major discovery about an enzyme's structure has opened a window on understanding DNA repair. Scientists at Duke University Medical Center have determined the structure of a nuclease that will help scientists to understand several DNA repair pathways, a welcome development for cancer research.

Nutlin-3a molecules stimulate signal to induce cell death and senescence in brain cancer

Researchers of Apoptosis and Cancer Group of the Bellvitge Biomedical Research Institute (IDIBELL) have found that a small molecule, Nutlin-3a, an antagonist of MDM2 protein, stimulates the signalling pathway of another protein, p53.

Exposure to air pollution may alter women's DNA and cause premenopausal breast cancer

Exposure to air pollution early in life and when a woman gives birth to her first child may alter her DNA and may be associated with premenopausal breast cancer later in life, researchers at the University at Buffalo have shown.

Genetically modified mosquitoes tested to prevent spread of malaria: Study

According to the latest study in the journal Nature, researchers from Imperial College London and the University of Washington, Seattle found that after making specific genetic changes to a few mosquitoes and then allowing them to breed could eventually dramatically reduce the spread of the deadly disease malaria.

Roche's cobas HPV Test receives FDA approval for cervical cancer screening

Roche announced today that the U.S. Food and Drug Administration (FDA) has approved the cobas HPV (Human Papillomavirus) Test which identifies women at highest risk for developing cervical cancer. This test will help physicians make early, more accurate decisions about patient care, which may prevent many women from developing this deadly disease.

Whole-genome sequencing could soon improve cancer survival rates

Cancer survival rates could improve soon with whole-genome sequencing, according to two studies published in the April 20, 2011, issue of the Journal of the American Medical Association that describe the first clinical applications of the high-tech process in patients with cancer.

Researchers discover new way to force cancer cells to self-destruct

Researchers at The Wistar Institute have found a new way to force cancer cells to self-destruct. Low doses of one anti-cancer drug currently in development, called Gamitrinib, sensitize tumor cells to a second drug, called TRAIL, also currently in clinical development as part of an anticancer regimen.
