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 shows how melanoma cells evade detection and destruction by immune cells

A dysfunctional immune system significantly contributes to the development of cancer. Several therapeutic strategies to activate the immune system to target cancer cells have been approved to treat different types of cancer, including melanoma.

Mitochondrial DNA mutations can reduce death risk in people with bowel cancer

Mutations in the DNA of the cell's energy 'factories' increases the chances of survival for people with bowel cancer, according to a study published today (Thursday) in Nature Metabolism.

Transposons can protect against certain blood cancers

New research has uncovered a surprising role for so-called "jumping" genes that are a source of genetic mutations responsible for a number of human diseases.

Accelerated cellular aging in depressed individuals associated with increased mortality risk

Cells from healthy individuals with major depressive disorder were found to have higher than expected rates of methylation at specific sites on their DNA, when compared to cells from healthy individuals without MDD, according to a study by a multidisciplinary team of Walter Reed Army Institute of Research and University of California San Francisco scientists, in collaboration with others.

Full assembly of human chromosome 8 reveals novel genes, disease risks

The full assembly of human chromosome 8 is reported this week in Nature. While on the outside this chromosome looks typical, being neither short nor long or distinctive, its DNA content and arrangement are of interest in primate and human evolution, in several immune and developmental disorders, and in chromosome sequencing structure and function generally.

Phase 2 clinical trial launched in Thailand to evaluate IL-15 agonist as therapy to reduce HIV reservoir

The U.S. Military HIV Research Program (MHRP) at the Walter Reed Army Institute of Research last week launched a Phase 2 clinical trial in Thailand to evaluate an interleukin-15 (IL-15) superagonist, ImmunityBio's Anktiva (also called N-803), administered during acute HIV infection as an experimental therapy to target establishment of the HIV reservoir at a very early stage.

IRB Barcelona researchers find the Achilles heel of some lung tumors

In cancer, personalized medicine takes advantage of the unique genetic changes in an individual tumor to find its vulnerabilities and fight it.

Microrna-29 molecule controls brain maturation in mammals

A team led by scientists at the UNC School of Medicine identified a molecule called microRNA-29 as a powerful controller of brain maturation in mammals. Deleting microRNA-29 in mice caused problems very similar to those seen in autism, epilepsy, and other neurodevelopmental conditions.

Study: H2AK119ub1 is necessary for maternal inheritance of H3K27me3

An epigenetic study at the RIKEN Center for Integrative Medical Sciences shows that in mouse egg cells, modifications to histone H2A at lysine 119 lay the groundwork for inherited DNA functional modifications from the mother.

PNA-based gene editing technique can advance gene discovery

In an article published in the April 8 issue of Nature, the National Institutes of Health's Somatic Cell Gene Editing Consortium provided a detailed update on the progress of their nationwide effort to develop safer and more effective methods to edit the genomes of disease-relevant somatic cells and reduce the burden of disease caused by genetic changes.

Racial diversity and poverty may influence heart-failure morbidity and mortality

Race associates with the risk of death from end-stage heart failure. So, identifying the molecular determinants of that risk may help the pursuit of the novel diagnosis and prognosis of heart failure, and its therapy.

Researchers characterize genetic intra-tumor heterogeneity across cancer genomes

Researchers at the Francis Crick Institute, as part of an international collaboration of scientists through the Pan-Cancer Analysis of Whole Genomes Consortium, have analyzed the whole genomes of tumor samples from over 2,600 patients with different types of cancer.

Gut microbiome communicates with horse’s cells to enhance their athletic performance

A horse’s gut microbiome communicates with its host by sending chemical signals to its cells, which has the effect of helping the horse to extend its energy output, finds a new study published in Frontiers in Molecular Biosciences.

Individuals with Major Depressive Disorder have accelerated cellular aging

Cells from individuals with Major Depressive Disorder (MDD) were found to have higher than expected rates of methylation at specific sites on their DNA, when compared to cells from healthy individuals without MDD, according to a study by a multidisciplinary team of UC San Francisco scientists, in collaboration with others.

New grant to Harvard Medical School is boosting efforts to understand and combat rare cancers

Curing cancer has been the dream of countless doctors and researchers over the decades. Yet some types of cancer, whether because they affect relatively few people or lack influential advocates, receive less attention and funding than others.
