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).

Young adults from disadvantaged neighborhoods show differences in the epigenome

The neighborhood a child grows up in may influence their health for years to come in previously invisible ways.

Near-infrared photoimmunotherapy could improve treatment for malignant lung cancer

Treating a rare type of malignant lung cancer could improve, thanks to near-infrared irradiation and a cancer-targeting compound. Nagoya University oncologist Kazuhide Sato and colleagues tested the treatment and published their findings in the journal Cells.

Differences in accumulation of genetic mutations could help predict lifespan, fertility

Differences in the rate that genetic mutations accumulate in healthy young adults could help predict the remaining lifespan in both sexes and the remaining years of fertility in women, according to the University of Utah Health scientists.

Widespread testing could help stop the spread of COVID-19

The world is now in the grips of a historic pandemic. The death toll from the novel coronavirus has climbed to more than 117,000 in the United States and 448,000 around the world.

Using stem cells to study the developmental effects of Neandertal DNA

Protocols that allow the transformation of human induced pluripotent stem cell (iPSC) lines into organoids have changed the way scientists can study developmental processes and enable them to decipher the interplay between genes and tissue formation, particularly for organs where primary tissue is not available.

Novel SARS-CoV-2 antibody cocktail impeccably mimics human antibody response

By using both humanized mice and convalescent patients, the researchers from the US and Singapore successfully generated non-competing and highly potent monoclonal antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein that could potentially be combined to form antibody cocktails. Their groundbreaking paper is published in the leading research journal Science.

Scientists use CRISPR tool to make rapid, precise cuts in genomic material

In a series of experiments using human cancer cell lines, scientists at Johns Hopkins Medicine say they have successfully used light as a trigger to make precise cuts in genomic material rapidly, using a molecular scalpel known as CRISPR, and observe how specialized cell proteins repair the exact spot where the gene was cut.

Study reveals new insight into Fuchs’ endothelial corneal dystrophy

The molecular changes that lead to Fuchs' endothelial corneal dystrophy (FECD) occur decades before the disease causes blurry vision and other noticeable symptoms in patients, new research by UT Southwestern scientists shows.

ACE2 and pattern recognition receptor genes increase with age

A recent study by researchers in California and published on the preprint server bioRxiv* in June 2020 shows that advancing age is associated with increased expression of pattern recognition receptor (PRR) genes and ACE2 receptors, possibly accounting in part for the increased severity of the disease in older adults.

BIA Separations launches novel PrimaS ligand technology to facilitate development of advanced therapies

BIA Separations, a leading bio-chromatography development and manufacturing company, today announced the introduction of its novel PrimaS ligand technology.

Even brief exposure to certain chemicals can prematurely age the liver epigenome

The epigenome is sometimes referred to as the "software" or "operating system" of the genome. It comprises small chemical modifications to DNA and the proteins that make up our chromosomes, and controls the activity of all the genes within the genome.

Mapping RNA sequences of therapeutic value in the SARS-CoV-2 genome

Now, in new research published on the preprint server bioRxiv European scientists have performed RNA structure probing to obtain a single-base resolution secondary structure map of the full SARS-CoV-2 coronavirus genome.

Antibiotic X-206 effective against SARS-CoV-2 in vitro

The current study published on the preprint server bioRxiv aims to understand how these compounds affect SARS-CoV-2 in vitro. The researchers from Aarhus University in Denmark examined 11 natural PEIs, with a single synthetic analog, screening them for inhibitory activity against the CPE of SARS-CoV-2 infecting cultured cells with overexpression of TMPRSS2, a serine protease that is instrumental in cleaving the spike protein of the virus.
