DNA News and Research

RSS

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).

Antibiotic exposure and its priming effect on disease-causing bacteria

Antibiotics save lives -- but using them also helps antibiotic-resistant strains evolve and spread. Each year, antibiotic-resistant bacteria infect some 2.8 million people in the United States, killing more than 35,000, according to the Centers for Disease Control and Prevention.

Scientists decode herpes simplex virus 1

Until now, scientists had assumed that there are about 80 so-called open reading frames (ORFs) in the genome of herpes simplex virus 1 (HSV-1).

Talazoparib did not show overall survival benefit in patients with advanced BRCA-mutated breast cancer

New data from the Phase III EMBRACA trial led by researchers at The University of Texas MD Anderson Cancer Center found the PARP inhibitor talazoparib did not demonstrate a statistically significant overall survival (OS) benefit for patients with metastatic HER2-negative breast cancer and mutations in the BRCA1/2 genes.

Researchers re-purpose cancer-fighting artificial antibodies for COVID-19

Researcher Paula Bates, John Trent, and Don Miller developed a therapeutic drug that could potentially block the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) responsible for the COVID-19 pandemic. Their research was initially aimed at helping patients suffering from multiple types of cancer.

Recombinant protein produces neutralizing COVID-19 antibodies in primate model

A new study reports the induction of high levels of neutralizing antibodies to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus causing the current pandemic of COVID-19. This promising finding was reported on the preprint server bioRxiv on April 2020.

Poor quality testing could increase number of COVID-19 infections

A new study published in the preprint open-access journal medRxiv in April 2020 assesses the value of untargeted testing for infection or immunity in COVID-19 vs. high-quality targeted testing in keeping down the number of infections while slowly relaxing lockdown measures.

Researchers discover physiological mechanisms underlying pediatric B-ALL

B-cell acute lymphoblastic leukemia (B-ALL) is characterized by the accumulation of abnormal immature B-cell precursors in the bone marrow and is the most common pediatric cancer.

UMD professor outlines new theoretical framework for heredity

The common view of heredity is that all information passed down from one generation to the next is stored in an organism's DNA. But Antony Jose, associate professor of cell biology and molecular genetics at the University of Maryland, disagrees.

Genomic sequencing shows COVID-19 spread patterns

Throughout the spread of the virus, genomic sequencing has played a role in epidemiologic tracking of the viral strains carried all over the world. Such strains are traced back to their origin by their unique mutations and help to link remote infections.

Using 'own' immune cells to fight infectious diseases including COVID-19

A provocative paper from Duke-NUS Medical School, published in the Journal of Experimental Medicine in March 2020, discusses the possibilities of creating new receptors on a sick person's own immune cells as a means of controlling the infection. This therapy is already being used to treat certain cancers with marked success.
