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).

New drug targeting genetic weakness could become first treatment for childhood brain cancer

A new type of drug that targets a genetic weakness in an untreatable childhood brain cancer could become the first ever treatment designed to target the disease.

Inexpensive DNA test can effectively screen women for cervical cancer in low-resource settings

Cervical cancer is a major issue in low- and middle-income countries due to the lack of adequate screening such as routine Pap smear testing.

Study finding promises new perspectives for treatment of Type 2 endometrial cancer

Brazilian scientists identify the predominant presence of a truncated variant of the p53 protein in amyloid aggregates in endometrial cancer cells. Such structures are related to the progression of this tumor.

Discovery of small-molecule inhibitors could enable precise control over CRISPR-Cas9 genome editing

The discovery of the first small-molecule inhibitors of the Streptococcus pyogenes Cas9 (SpCas9) protein could enable more precise control over CRISPR-Cas9-based genome editing, researchers report May 2 in the journal Cell.

Targeting antidiuretic hormone vasopressin shows promise for autism

Autism is a complex neurodevelopmental disorder with no known drug treatment up until now. Researchers have finally found tweaking certain hormones could help patients with autism. There were two independent clinical trials including children and adults with autism that altered the effects of the hormone vasopressin and to assess the effects on social functioning.

Biomarker may help predict first treatment option for metastatic colorectal cancer patients

Foundational research by a City of Hope physician-scientist and his colleagues could one day help metastatic colorectal cancer patients decide whether to choose immunotherapy or chemotherapy as their first treatment option.

Deletion of ATDC gene prevents development of pancreatic cancer in mice

The action of a gene called ATDC is required for the development of pancreatic cancer, a new study finds.

Study shows how neutrophils exacerbate atherosclerosis by inducing smooth muscle-cell death

Many chronic disorders arise from misdirected immune responses. A Ludwig-Maximilians-Universitaet in Munich team led by Oliver Söhnlein now shows that neutrophils exacerbate atherosclerosis by inducing smooth muscle-cell death and that a tailored peptide inhibits the process.

Sussex scientists discover new genetic defect that causes intellectual disability

Researchers at the University of Sussex have discovered a new genetic defect which causes a form of intellectual disability; a finding that will improve screening programmes and help to end a 'diagnostic odyssey' for families across the globe.

Children under 3 years old are most vulnerable to the effects of adversity, study finds

A Massachusetts General Hospital study has found evidence that children under 3 years old are most the vulnerable to the effects of adversity - experiences including poverty, family and financial instability, and abuse - on their epigenetic profiles, chemical tags that alter gene expression and may have consequences for future mental health.
