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).

Nose drops of modified 'friendly' bacteria offer protection against meningitis

A world-first trial has shown that nose drops of modified 'friendly' bacteria protect against meningitis.

Novel method of gene therapy promises to transform the treatment of rare genetic disorder

A novel method of gene therapy is helping children born with a rare genetic disorder called AADC deficiency that causes severe physical and developmental disabilities.

Researchers discover new genetic driver of autism and other developmental disorders

A research group including Kobe University's Professor TAKUMI Toru (also a Senior Visiting Scientist at RIKEN Center for Biosystems Dynamics Research) and Assistant Professor TAMADA Kota, both of the Physiology Division in the Graduate School of Medicine, has revealed a causal gene (Necdin, NDN) in autism model mice that have the chromosomal abnormality called copy number variation.

Mating can turn off a single gene for multiple generations, study shows

Evidence suggests that what happens in one generation--diet, toxin exposure, trauma, fear--can have lasting effects on future generations.

Research reveals how mitochondria keep their reactive oxygen species production in check

Mitochondria, the powerhouse of the cell, convert sustenance into energy, fueling the cell's activities. In addition to power, mitochondria also produce reactive oxygen species, byproduct molecules primed to help facilitate communication among the other units in the cells.

WHO and HRP launch new guideline for screening and treatment of cervical cancer

Too many women worldwide – particularly the poorest women – continue to die from cervical cancer; a disease which is both preventable and treatable.

Study uncovers mutations in Polycomb group gene as underlying cause of novel neurological disorder

A multi-institutional study has discovered spontaneous mutations in RNF2 (RING2) gene as the underlying cause of a novel neurological disorder.

Study uncovers the complex cellular mechanisms of Ebola virus

Mount Sinai researchers have uncovered the complex cellular mechanisms of the Ebola virus, which could help explain its severe toll on humans and identify potential pathways to treatment and prevention.

Researchers determine the structure of nanomachine essential for functioning of mTOR

The principle that form follows function does not only apply to design and architecture. It also applies to biology

Optical genome mapping could change the existing workflow within cytogenetic laboratories

Dutch-French research shows that Optical Genome Mapping (OGM) detects abnormalities in chromosomes and DNA very quickly, effectively and accurately. Sometimes even better than all existing techniques together, as they describe in two proof-of-concept studies published in the American Journal of Human Genetics.

Study: Gene editing therapy for early-stage Huntington’s disease may have long-lasting benefits

In a new study on mice, Johns Hopkins Medicine researchers report that using MRI scans to measure blood volume in the brain can serve as a noninvasive way to potentially track the progress of gene editing therapies for early-stage Huntington's disease, a neurodegenerative disorder that attacks brain cells.

Rare genetic variants have a big impact on the risk of developing type 2 diabetes

Scientists at the University of Cambridge have identified rare genetic variants - carried by one in 3,000 people - that have a larger impact on the risk of developing type 2 diabetes than any previously identified genetic effect.

Study addresses potential interrelations between AID/APOBECs and the SARS-CoV-2 virus

Together with their multifaceted action mechanisms, activation-induced cytidine deaminase (AID) and so-called APOBEC proteins are important factors in the body's immune response and offer fast and effective protection against a large number of DNA and RNA viruses.

Uncovering cellular mechanism related to gene silencing therapies

Gene silencing therapies are used to interfere with, or "silence", the expression of genes that are associated with disorders. Now, a team at TMDU has uncovered some of the cellular mechanisms by which the silencing therapies act in cells.

Shape of extracellular vesicles in body fluids could be a biomarker for identifying cancer types

A recent study by scientists from Japanese universities has shown that the shape of cell-derived nanoparticles, known as "extracellular vesicles" (EVs), in body fluids could be a biomarker for identifying types of cancer.

Study explores the intersection of culture and health among Mexican women and children

As we move through life, our bodies get older. Aging is inevitable, but how fast it happens can vary considerably. Physical and environmental stressors can accelerate the process, and culture may interact with biology in ways that are not fully explored.
