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).

NEK7 enzyme acts as on-off switch in innate immune system

UT Southwestern Medical Center and California researchers today provide the first report that an enzyme previously known solely for its role in cell division also acts as an on-off switch in the innate immune system -- the body's first defense against infection.

Stanford researchers invent new technique to dramatically accelerate protein evolution

All living things require proteins, members of a vast family of molecules that nature "makes to order" according to the blueprints in DNA.

Innovative DNA technology enables faster and more effective diagnosis of TB cases

Whole Genome Sequencing is a faster, cheaper and more effective way of diagnosing tuberculosis says a new study published in the journal Lancet Respiratory Medicine.

Faulty gene function responsible for reducing survival times of leukaemia patients

Researchers have identified a genetic fault in some leukaemia patients that could be responsible for halving survival times after diagnosis compared to patients without the fault – an average reduction from 16 years to seven years. T

Research reveals genetic variants linked to treatment-related complications in children with blood diseases

Research to be presented today at the 57th American Society of Hematology Annual Meeting and Exposition reveals genetic variants that are associated with disease severity and treatment-related complications in children with blood diseases.

Genetic variations associated with increased risk for osteonecrosis in young ALL patients

Variations in genes involved in normal bone development are associated with an 8- to 15-fold increased risk for osteonecrosis in young patients with acute lymphoblastic leukemia (ALL), according to research led by St. Jude Children's Research Hospital and Children's Oncology Group investigators.

HBsAg may persist in chronic HBV patients beyond seroclearance

The use of a highly sensitive assay for the detection of hepatitis B surface antigen suggests that HBsAg negativity as evaluated by the conventional test may not be indicative of seroclearance in patients with chronic hepatitis B virus infection.

Bacteriophage therapy: an alternative to antibiotics? An interview Professor Clokie

A phage is a virus that infects a bacterium. People often get very confused about what the difference is between a virus and a bacterium. A virus, like a bacterium, is also a microorganism, but unlike bacteria, it needs to have a host to be able to replicate and propagate.

Genetic information of patients with IBD could provide road map for more effective treatments

Genetic variation in patients with inflammatory bowel disease (IBD) appears to play a major role in determining how sick they will become and could provide a road map for more effective treatments.

The Importance of Flexibility in Spectrophotometry

News-Medical speaks to Jessica Geisler about the need for flexible spectrophotometers that can handle a range of measurement types.

Discovery may lead to potential new therapeutic approach to eradicate blood cancers

An international team of scientists, headed by researchers at UC San Diego School of Medicine and UC San Diego Moores Cancer Center, report that decreases in a specific group of proteins trigger changes in the cancer microenvironment that accelerate growth and development of therapy-resistant cancer stem cells (CSCs).

TGen, Barrow researchers identify genetic risk factors linked to stress-induced cardiomyopathy

Researchers at the Translational Genomics Research Institute and Barrow Neurological Institute have for the first time identified genetic risk factors that are linked to stress-induced cardiomyopathy (SIC), a rare type of heart disease.

Low levels of BRCA1 protein in the brain linked to dementia

Mutant forms of breast cancer factor 1 (BRCA1) are associated with breast and ovarian cancers but according to new findings, in the brain the normal BRCA1 gene product may also be linked to Alzheimer's disease. The results, published in Nature Communications, suggest that low levels of BRCA1 protein in the brain may contribute to dementia.

Johns Hopkins researchers develop method to turn stem cells into retinal ganglion cells

Johns Hopkins researchers have developed a method to efficiently turn human stem cells into retinal ganglion cells, the type of nerve cells located within the retina that transmit visual signals from the eye to the brain. Death and dysfunction of these cells cause vision loss in conditions like glaucoma and multiple sclerosis.

DNA sequence variation can influence gene activity in developing human brain

An international research collaboration has shed new light on how DNA sequence variation can influence gene activity in the developing human brain.

Research sheds light on genetic factors involved in autoimmune diseases

A collaboration between researchers at the Babraham Institute and the University of Manchester has mapped the physical connections occurring in the genome to shed light on the parts of the genome involved in autoimmune diseases. Using a new technique, called Capture Hi-C, the team revealed novel insights into how changes in the genetic sequence have a biological effect and increase the risk of disease.
