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).

Human microbiome contains unique fingerprints, shows study

A new study shows that the microbial communities we carry in and on our bodies—known as the human microbiome—have the potential to uniquely identify individuals, much like a fingerprint.

MD Anderson researchers find significant clinical variations among liver cancer patients

Significant clinical variations exist among patients with the most common type of liver cancer called hepatocellular carcinoma (HCC), depending on the viral cause of the disease -hepatitis B virus (HBV) or hepatitis C virus (HCV). These differences suggest that hepatitis status should be considered when developing treatment plans for newly diagnosed patients, according to researchers at The University of Texas MD Anderson Cancer Center.

Historic mining pollution in south west England reduces genetic diversity of brown trout

Pollution from historic mining activities in south west England has led to a reduction in genetic diversity of brown trout according to new research from the University of Exeter.

Researchers submit patent application for drug that could destroy acute lymphoblastic leukemia

A patent application for a drug that could destroy the deadly childhood disease known as acute lymphoblastic leukemia — and potentially other cancers as well — has been submitted by researchers at Sandia National Laboratories, the University of Maryland and the MD Anderson Cancer Center in Houston.

CNIO researchers identify new strategy to combat cancer

Scientists from the Spanish National Cancer Research Centre have discovered a new strategy to fight cancer, which is very different from those described to date. Their work shows for the first time that telomeres -- the structures protecting the ends of the chromosomes -- may represent an effective anti-cancer target: by blocking the TRF1 gene, which is essential for the telomeres, they have shown dramatic improvements in mice with lung cancer.

UCL-led team develops new technique to find resistant TB faster

The time needed to genetically sequence the bacteria causing tuberculosis (Mtb) from patient samples has been reduced from weeks to days using a new technique developed by a UCL-led team. This could help health service providers to better treat disease, control transmission of this infection, and monitor outbreaks.

Discovery could help identify molecules that selectively target cancer cells

A new family of molecules that kill cancer cells and protect healthy cells could be used to treat a number of different cancers, including cervical, breast, ovarian and lung cancers. Research published in EBioMedicine shows that as well as targeting and killing cancer cells, the molecules generate a protective effect against toxic chemicals in healthy cells.

Childhood cancer survivors more likely to be obese than healthy peers

Childhood cancer survivors - especially those whose treatment included brain irradiation or chemotherapy with glucocorticoids - are 14 percent more likely to be obese than their healthy peers.

Novel insights into the genetics of autism

A study of 2,377 children with autism, their parents and siblings has revealed novel insights into the genetics of the condition.

Researchers identify three genes involved in choroid plexus carcinoma

Researchers have identified three genes that play a pivotal role in the brain tumor choroid plexus carcinoma (CPC), a discovery that lays the groundwork for more effective treatment of this rare, often fatal cancer. St. Jude Children's Research Hospital scientists led the study, which appears today in the journal Cancer Cell.

MD Anderson researchers discover link between telomere degeneration and MDS

A study revealing fresh insight about chromosome "tails" called telomeres may provide scientists with a new way to look at developing treatments or even preventing a group of blood cell disorders known as myelodysplastic syndromes (MDS).

Study finds extremely high levels of cardiovascular risk factors in people with psychosis

Extremely high levels of cardiovascular risk factors have been found in people with established psychosis, with central obesity evident in over 80 per cent of participants, in a study by researchers from the NIHR Biomedical Research Centre at the South London and Maudsley NHS Foundation Trust and King's College London.

9-Valent HPV vaccine can potentially prevent 80% of cervical cancers in the U.S.

The new 9-valent human papillomavirus vaccine, can potentially prevent 80 percent of cervical cancers in the United States, if given to all 11- or 12-year-old children before they are exposed to the virus.

Scientists identify gene that causes hereditary hypertension and brachydactyly type E

Individuals with this altered gene have hereditary hypertension (high blood pressure) and at the same time a skeletal malformation called brachydactyly type E, which is characterized by unusually short fingers and toes. The effect on blood pressure is so serious that -- if left untreated -- it most often leads to death before age fifty.

Researchers discover potential mechanism to combat haemorrhagic diseases

A potential mechanism to combat diseases caused by haemorrhagic fever viruses has been discovered by researchers at the University of Montreal's Department of Biochemistry and Molecular Medicine. These diseases present a dramatic risk to human health as they often spread quickly and kill a high percentage of infected individuals, as demonstrated by the recent Ebola outbreaks.

Study sheds light on developing more targeted therapies against medulloblastoma

St. Jude Children's Research Hospital scientists have gained ground toward developing more targeted therapies for the most common childhood brain tumor.

Moffitt scientists examine why prostate cancer patients who receive ADT experience hot flashes

Androgen deprivation therapy (ADT) is a common treatment option for patients with advanced stage prostate cancer. But nearly 80 percent of patients who receive ADT report experiencing hot flashes during and after treatment. Moffitt Cancer Center researchers are working to determine what genetic factors and other characteristics might make prostate cancer patients more likely to experience hot flashes during and after therapy.

Researchers identify promising combination strategy for treating glioblastomas

Therapies that specifically target mutations in a person's cancer have been much-heralded in recent years, yet cancer cells often find a way around them. To address this, researchers at University of California, San Diego School of Medicine and Moores Cancer Center identified a promising combinatorial approach to treating glioblastomas, the most common form of primary brain cancer.

Danish researchers discover way to map more than one protein at a time

Danish researchers at the University of Copenhagen have discovered how to map more than one protein at a time, when proteins repair damaged DNA. It is a discovery that will help accelerate the process of developing better and gentler cancer treatments.
