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).

New legislation allows physicians in Texas to treat chronic Lyme disease

Summertime, when kids and grown-ups abandon the confines of the indoors and head outside to camp, hike, fish and commune with nature -- and all of her friends. Flies, mosquitoes and ticks are just a few of the critters that go along with summer outdoors, and we all do our best to avoid the biting and stinging insects, but what happens if you are accosted by a tick? What are the myths behind Lyme disease and other tick-borne diseases in Texas?.

Novel DNA sensing pathway linked to increased susceptibility to malaria

Scientists at the University of Massachusetts Medical School have uncovered a novel DNA-sensing pathway important to the triggering of an innate immune response for malaria. Activation of this pathway appears to stimulate production of an overabundance of type-1 interferon by the immune system that may contribute to inflammation and fever in malaria patients and could play a part in susceptibility for the most common and lethal form of malaria known as plasmodium falciparum.

Higher levels of B cells make women more prone to autoimmune diseases

Researchers at National Jewish Health have discovered a type of cell that may contribute to autoimmune disease and suggests why diseases such as lupus, multiple sclerosis and rheumatoid arthritis strike women more frequently than men. The cells, a subset of immune-system B cells, make autoantibodies, which bind to and attack the body's own tissue.

Specific microRNA cluster could play a key role in retinoblastoma development

New research from a team including several Carnegie scientists demonstrates that a specific small segment of RNA could play a key role in the growth of a type of malignant childhood eye tumor called retinoblastoma.

EWS protein detects and corrects DNA damage in Ewing's sarcoma

Researchers from the CRG have discovered that ultraviolet light affects the function of the protein EWS, the mutation of which is responsible for Ewing's sarcoma. The results, to be published on 5th August in the journal Molecular Cell, indicate that the EWS protein has a protective effect on DNA.

Researchers identify genes that play a key role in pain perception

By working with individuals suffering from a severe disorder that causes sensory neurons to degenerate, researchers at the University of Montreal Hospital and CHU Sainte-Justine Hospital have discovered how a specific genetic mutation causes their patients' condition, which in turn has revealed more information about the mechanisms in our bodies which enable us to sense pain.

Conference to discuss novel studies that address how inherited genes cause breast cancer

A woman's ethnicity as well as her genetic makeup are two of the main risk factors for hereditary breast cancer. Research into understanding and treating hereditary breast cancer will be presented today at the Era of Hope conference, a scientific meeting hosted by the Department of Defense Breast Cancer Research Program.

Researchers sample hydrogenotrophic microbes in the healthy human colon

They make up less than one-hundredth of 1 percent of the microbes that live in the colon, but the bacteria and archaea that sop up hydrogen in the gut are fundamental to colon health. In a new study, researchers take a first look at these "hydrogenotrophic" microbes, mapping where they live and how abundant they are in different parts of the lower intestine.
