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).

University of Leicester awarded BBSRC grant to explore three key areas that impact human health

The University of Leicester has been awarded over £1.5 million in order to advance knowledge and understanding in three key areas that impact on health.

Researchers find new way to prevent inflammation, accelerate the skin's healing process

Most products on the market today that are used to treat skin problems target the effects of the disease or wound such as inflammation, which can prolong the healing process and result in scarring. However, LSU Assistant Professor Wei Xu and collaborators at Northwestern University discovered a new way to prevent inflammation and to speed up the skin's healing process.

Researchers team up to evaluate biological and genetic differences of GI cancers in race, ethnicity

Americans of African descent are at a significantly higher risk for developing and dying from Gastrointestinal (GI) cancers, which include colorectal and pancreatic cancers, compared to individuals who are of Caucasian descent.

Liquid biopsy provides physicians with up-to-date information about patient's cancer

A team of researchers, including scientists from the Translational Genomics Research Institute, has reported that analyzing circulating tumor DNA (ctDNA) can track how a patient's cancer evolves and responds to treatment.

Researchers identify mechanisms underlying postnatal organ maturation

Any expectant mother will tell you that she wants her baby's organs to develop properly in the womb. What she may not realize, however, is that a child's internal organs continue to develop for months and years after birth. This critical period is full of cellular changes that transform the organization and function of most tissues. But the exact mechanisms underlying postnatal organ maturation are still a mystery.

Scientists create supercharged blood cell that may heal major wounds, block inflammation

Faculty of Medicine scientists have created a "Franken-platelet" - a supercharged blood cell - that might be capable of healing major wounds, busting clots or blocking inflammation.

Nucala (mepolizumab) approved for treatment of asthma patients

The U.S. Food and Drug Administration today approved Nucala (mepolizumab) for use with other asthma medicines for the maintenance treatment of asthma in patients age 12 years and older. Nucala is approved for patients who have a history of severe asthma attacks (exacerbations) despite receiving their current asthma medicines.

Tumour DNA in the blood can accurately monitor cancer in real time

Scientists have shown for the first time that tumour DNA shed into the bloodstream can be used to track cancers in real time as they evolve and respond to treatment, according to a new Cancer Research UK study published in the journal Nature Communications today (Wednesday).

OncoSec signs definitive agreements to purchase $7.5 million of securities in registered direct offering

OncoSec Medical Incorporated, a company developing DNA-based intratumoral cancer immunotherapies, announced today that it has entered into definitive agreements with institutional investors to purchase approximately $7.5 million of securities in a registered direct offering.

Researchers use genomic techniques to show why different strains of Salmonella infect particular animal species

It's called bird flu for a reason. Particular characteristics about the influenza virus known as H5N1 allow it to primarily affect avifauna, though in some worrying cases the disease has been passed to humans.

Cancer DNA in patient's bloodstream could help deliver personalized treatment for liver cancer

Fragments of cancer DNA circulating in a patient's bloodstream could help doctors deliver more personalized treatment for liver cancer, Japanese researchers report.

Findings provide a step towards personalized cancer therapy

Oxford University researchers have found the Achilles heel of certain cancer cells - mutations in a gene called SETD2. Their findings will be presented to the National Cancer Research Institute conference in Liverpool this Monday (2 Nov 15).

New method helps study chaotic genomes of cancer cells more precisely than ever before

Scientists of the Luxembourg Centre for Systems Biomedicine of the University of Luxembourg have developed a method for analysing the genome of cancer cells more precisely than ever before.

Key protein controls stem cell properties that could make them useful in regenerative medicine

A key protein controls stem cell properties that could make them more useful in regenerative medicine, according to a study led by Mount Sinai researchers and published online today in the journal Cell Stem Cell.

UCSD researchers develop new computational strategy to find tumor-shrinking molecules

Patients with glioblastoma, a type of malignant brain tumor, usually survive fewer than 15 months following diagnosis. Since there are no effective treatments for the deadly disease, University of California, San Diego researchers developed a new computational strategy to search for molecules that could be developed into glioblastoma drugs. In mouse models of human glioblastoma, one molecule they found shrank the average tumor size by half.

Cologuard stool DNA test: An accurate screening option for Alaska Native people with colorectal cancer

Cologuard stool DNA testing for colorectal cancer was found to be an accurate noninvasive screening option for Alaska Native people, a population with one of world's highest rates of colorectal cancer, concluded researchers from the Alaska Native Tribal Health Consortium and Mayo Clinic.

RNA profiles of tumor-educated platelets may diagnose cancer, identify potential therapeutic approaches

Analysis of tumor RNA carried in platelets - blood components best known for their role in clotting - may prove to be more useful than other "liquid biopsy" technologies for diagnosing cancer and determining its primary location and potential therapeutic approaches.
