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).

Link not found between child sexual abuse and telomere length

Researchers and medical experts have long known that child sexual abuse has profoundly negative effects on the health of survivors; however, an international team of researchers was not able to find a link between the abuse and telomere length, considered an indicator of cellular aging and health.

Multiplication of ecDNA genes present in many cancer types, drives poor patients outcomes

The multiplication of genes located in extrachromosomal DNA that have the potential to cause cancer drives poor patient outcomes across many cancer types, according to a Nature Genetics study published Aug. 17, 2020 by a team of researchers including Professors Vineet Bafna and Dr.Paul Mischel of the University of California San Diego and Professor Roel Verhaak of Jackson Laboratories.

New type of immunotherapy extends survival of mice with triple negative breast tumors

Immunotherapies for cancer -; treatments that prime the immune system to attack tumors -; are valuable weapons in the anti-cancer arsenal. But some cancers are more difficult to target with this strategy than others.

Research shows how a protein stops cells from attacking their own DNA

Viruses multiply by injecting their DNA into a host cell. Once it enters the intracellular fluid, this foreign material triggers a defense mechanism known as the cGAS-STING pathway.

Study suggests mutations have helped Brown Howlers to deal with yellow fever virus

At the start of her 2008 field season at El Parque El Piñalito in the Misiones province in northeastern Argentina, Ilaria Agostini knew something was terribly wrong. Agostini has studied Misiones' two howler monkey species since 2005--brown (Alouatta guariba clamitans) and black and gold (A. caraya) howlers.
