DNA News and Research

RSS

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).

How HIV kills CD4 T cells

Researchers appear to have an explanation for a longstanding question in HIV biology: how it is that the virus kills so many CD4 T cells, despite the fact that most of them appear to be "bystander" cells that are themselves not productively infected. That loss of CD4 T cells marks the progression from HIV infection to full-blown AIDS, explain the researchers who report their findings in studies of human tonsils and spleens in the November 24th issue of Cell, a Cell Press publication.

Researchers identify trigger mechanism for quality control checkpoint in cell division process

Researchers from Huntsman Cancer Institute (HCI) at the University of Utah report that they have identified a previously undiscovered trigger mechanism for a quality control checkpoint at the very end of the cell division process in a paper to be published in the November 29 issue of The Journal of Cell Biology and online today.

Largest genomic study of human medulloblastomas

Medulloblastomas are the most common malignant brain tumors of childhood, with 40 to 50 percent overall mortality. One of the greatest challenges in treating them is that they vary substantially from patient to patient. In the largest genomic study of human medulloblastomas to date, researchers from Children's Hospital Boston, together with collaborators, have identified six subtypes with distinct molecular "fingerprints" that will improve doctors' ability to direct and individualize treatment.

Mother’s high-fat diet alters fetal genes that regulate circadian rhythm: Study

The link between sleeping and obesity is drawn tighter as a new research published online in the FASEB Journal study shows that what your mother ate when she was pregnant may make you obese or overweight by altering the function of genes (epigenetic changes) that regulate circadian rhythm.

Research indicates possible danger of cancerous tissue development by using stem cells

Research work carried out at the Hebrew University of Jerusalem arouses a cautionary warning in the growing field of the development of stem cells as a means for future treatment of patients through replacement of diseased or damaged tissues by using the patient's own stem cells. The research indicates a possible danger of cancerous tissue development in the use of such cells.
