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).

Most synonymous genetic mutations are strongly harmful, study shows

In the early 1960s, University of Michigan alumnus Marshall Nirenberg and a few other scientists deciphered the genetic code of life, determining the rules by which information in DNA molecules is translated into proteins, the working parts of living cells.

Study identifies an epigenetic regulator that suppresses pathogenic events in rheumatoid arthritis

Rheumatoid arthritis (RA) is characterized by chronic inflammation of synovium, eventually leading to joint destruction. Epigenetic alteration (the mechanism of gene expression regulation without DNA sequence changes), such as low levels of DNA methylation, is one of the factors which worsens the RA state.

Scientists provide crucial insights into the roles of inflammation and oxidative stress in certain cancers

Rampant inflammation has long been linked to cancer but exactly how it pushes healthy cells to transform into malignant ones has remained a mystery.

Traditional methods of testing may not be enough to detect low levels of high-risk salmonella

Poultry is responsible for more than one out of every five cases of salmonella infection in the U.S. But traditional methods of testing the chicken you grab off the grocery shelf may not be enough to detect all strains of the bacteria, according to new research from the University of Georgia.

New FR-targeting, micropinocytosis-mediated bioconjugate attacks K-Ras mutant pancreatic cancer

Often undetected until it has progressed to an advanced stage, pancreatic ductal adenocarcinoma (PDAC) is a lethal cancer.

New fluorogenic probe could quickly detect the presence of influenza A virus

The influenza A virus, which is responsible for seasonal flu outbreaks, is also the only influenza virus that has previously caused flu pandemics.

Study finds striking epigenetic differences in the airway cells of adult children born to asthmatic mothers

Asthma is a chronic condition that affects 25 million people in the United States. Having a mother with asthma is an important risk factor and a new study may explain why.

Study offers recommendations for improving statistical inference in population genomics

The second century Alexandrian astronomer and mathematician Claudius Ptolemy had a grand ambition. Hoping to make sense of the motion of stars and the paths of planets, he published a magisterial treatise on the subject, known as the Almagest.

Drug combination yields highest response and longest survival rates for patients with pancreatic NETs

Very few treatment options are available to patients with advanced pancreatic neuroendocrine tumors (NETs), but researchers at the Yale Cancer Center and Yale New Haven Health's Smilow Cancer Hospital found that patients treated with a combination of capecitabine and temozolomide had longer progression-free survival rates than those treated with temozolomide alone.

Persistence of viral RNA following acute infection

Professor Diane Griffin from the Johns Hopkins Bloomberg School of Public Health, USA, has recently explained the persistence mechanism of viral RNA in the human body after clinical recovery from acute infection.

The frequency and nature of RNA errors in both SARS-CoV-2 and its vaccine

A recent article demonstrated that SARS-CoV-2 mutants and vaccine variability stem from ribonucleic acid polymerase inaccuracy.

Link between COVID-19 severity and microbiome of saliva and nasopharynx

In a recent study posted to the bioRxiv* preprint server, researchers profiled the salivary and nasopharyngeal microbiomes of coronavirus disease 2019 (COVID-19) patients and determined the association between the microbiomes and COVID-19 severity.

CRISPR-based diagnostics for SARS-CoV-2 detection

In a recent study posted to the Journal of Biochemical and Molecular Toxicology, researchers reviewed clustered regularly interspaced short palindromic repeats (CRISPR)-based diagnostics for detecting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
