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).

DNA repair mutations act as a switch for bowel cancer

Bowel cancer cells have the ability to regulate their growth using a genetic on-off switch to maximize their chances of survival, a phenomenon that's been observed for the first time by researchers at UCL and University Medical Center Utrecht.

Researchers discover rare types of helper T cells associated with immune disorders

Researchers led by Yasuhiro Murakawa at the RIKEN Center for Integrative Medical Sciences (IMS) and Kyoto University in Japan and IFOM ETS in Italy have discovered several rare types of helper T cells that are associated with immune disorders such as multiple sclerosis, rheumatoid arthritis, and even asthma.

More than 1,000 small changes in DNA identified that influence age of first period

Researchers examined nearly 800,000 women's DNA to explore puberty timing complexities. They identified signals related to menarche timing and investigated their influence on puberty onset.

New study reveals how RNA polymerase opens the transcription bubble in real time

Every living cell transcribes DNA into RNA. This process begins when an enzyme called RNA polymerase (RNAP) clamps onto DNA.

Innovative 3D printer-based test enhances early detection of Chagas disease in newborns

An innovative test that combines a DNA extraction system inspired by a modified 3D printer (PrintrLab) with loop-mediated isothermal molecular amplification (LAMP) could be used to detect T. cruzi infection -responsible for Chagas disease- in newborns.

Protein nanocages: A promising frontier in mRNA therapeutics

In recent years, messenger RNA (mRNA) has emerged as a promising avenue for accurate and potent therapeutic interventions. Unlike DNA drugs, mRNA can express genetic information without the risk of integrating into the host genome.

Key differences in RNA editing found between postmortem and living brain

Researchers examined the adenosine-to-inosine (A-to-I) nucleoside editing of postmortem and live prefrontal cortical tissues.

Gene discovery points to oxytocin for depression

While investigating two boys from different families with severe obesity, anxiety, autism, and behavioural problems triggered by sounds or smells, a team led by scientists at the University of Cambridge, UK, and Baylor College of Medicine, Houston, USA, discovered that the boys were missing a single gene, known as TRPC5, which sits on the X chromosome.

New HIV test targets neglected strains in global cure hunt

A multinational team led by Weill Cornell Medicine investigators developed a test that will help measure the persistence of HIV in people affected by viral strains found predominantly in Africa - a vital tool in the search for an HIV cure that will benefit patients around the world.

AI uncovers potential cancer drivers hidden in 'junk' regions of DNA

Using artificial intelligence, Garvan Institute researchers have found potential cancer drivers hidden in so-called 'junk' regions of DNA, opening up possibilities for a new approach to diagnosis and treatment.

Ribosomes and ZAK protein spur the cell's initial response to UV radiation damage

In a recent study, researchers at Johns Hopkins Medicine suggest the cell's messenger RNA (mRNA) - the major translator and regulator of genetic material - along with a critical protein called ZAK, spur the cell's initial response to UV radiation damage and play a critical role in whether the cell lives or dies.

From Africa to Eurasia: Genetic insights into human migration and cold adaptation

"Who are we and where do we come from?" This quintessential question has intrigued humanity for millennia.

Modulating gene expression using small molecules

The correct functioning of cells relies heavily on the ability to finely control gene expression, a complex process by which the information contained in DNA is copied into RNA to eventually give rise to all the proteins and most of the regulatory molecules in the cell.
