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 study may pave way for novel therapeutic strategies for COVID-19

An international and multidisciplinary team led by researchers at the University of Oxford, University of Glasgow, and University of Heidelberg, has uncovered the interactions that SARS-CoV-2 RNA establishes with the host cell, many of which are fundamental for infection.

New testing protocol for SARS-CoV-2 can process thousands of samples within 48 hours

Researchers at the Vienna BioCenter designed a testing protocol for SARS-CoV-2 that can process tens of thousands of samples in less than 48 hours. The method, called SARSeq, is published in the journal Nature Communications and could be adapted to many more pathogens.

Study shows that telomeres shorten most rapidly during early childhood

Telomeres are protective caps on DNA that shorten as we grow older. Now, one of the first studies to examine telomere length (TL) in childhood finds that the initial setting of TL during prenatal development and in the first years of life may determine one's TL throughout childhood and potentially even into adulthood or older age.

The potential therapeutic value of CDK6 inhibitors in critical COVID-19

While drug repurposing has been explored in the context of the current coronavirus disease 2019 (COVID-19) pandemic, the success of this strategy has been limited so far. A new study, released as a preprint on the medRxiv* server, describes a new method of identifying a promising hit among drugs already in use.

New peptide-like molecules could treat herpes, COVID-19, and the common cold

Among the powerful biochemicals of the human immune system, peptides are one of the best.

Researchers are developing first prognostic, therapeutic epigenetic biomarker for pancreatic cancer patients

By 2030, pancreatic ductal adenocarcinoma (PDAC), the most lethal form of pancreatic cancer, is projected to become the second leading cause of cancer-related deaths in the United States.

Study indicates that certain anti-cancer therapies may hasten cellular aging

New research indicates that certain anti-cancer therapies may hasten cellular aging, where changes in the DNA of patients may contribute to greater inflammation and fatigue.

Research suggests Garcinia kola extract might suppress severe COVID-19 cytokine storms

Researchers in the UK and Nigeria have conducted a study showing that Garcinia kola seed extract and garcinoic acid may provide therapeutic benefits in the late stage of severe coronavirus disease 2019 (COVID-19) and other coronavirus infections.

Specific enzymes protect the human skin and body from microbes, viruses

The human body is constantly exposed to various environmental actors, from viruses to bacteria to fungi, but most of these microbial organisms provoke little or no response from our skin, which is charged with monitoring and protecting from external dangers.

Study shows how human bodies develop from a single cell

New insights into how our bodies come into being from a single cell have been generated by researchers at the Wellcome Sanger Institute, the Wellcome-MRC Cambridge Stem Cell Institute and the University of Cambridge.

New study may lead to better treatments for prostate, ovarian, and breast cancers

Researchers at UVA Cancer Center have unveiled important new insights into how hormones known as androgens act on our cells – and the discovery could boost efforts to develop better treatments for prostate, ovarian and breast cancers.

SARS-CoV-2 spike mutation can independently predict viral evolution

A team of scientists from Portugal has recently estimated the rate of mutation in two circulating variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) using experimental evolution methods. Their findings reveal that in a condition with no immune surveillance, SARS-CoV-2 can potentially undergo evolution during the first stages of infection. The study is currently available on the bioRxiv* preprint server.

Plastic chemicals can induce changes in gene that is vital for neurological development

The chemical bisphenol F (found in plastics) can induce changes in a gene that is vital for neurological development. This discovery was made by researchers at the universities of Uppsala and Karlstad, Sweden.

Protein-based vaccines against SARS-CoV-2 may provide advantages over mRNA-based vaccines

Researchers in the UK have developed a protein-based subunit vaccine directed against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that could serve as an alternative to the mRNA-based vaccines currently approved for protecting against coronavirus disease 2019 (COVID-19).

Secondhand smoke during pregnancy linked to epigenetic changes in babies

Nearly a quarter of pregnant women say they've been around secondhand smoke - in their homes, at work, around a friend or relative - which, according to new research.

Lengthy treatment with low-dose 6-mercaptopurine inhibits resistant triple-negative breast cancer cells

The cover for issue 7 of Oncotarget features Figure 5, "SUM149-MA cells surviving a 6-MP treatment are sensitive to chemotherapeutic drugs," published in "Inhibition of resistant triple-negative breast cancer cells with low-dose 6-mercaptopurine and 5-azacitidine" by Singh, et al. which reported that the authors have reported that a lengthy treatment with low-dose 6-mercaptopurine, a clinically useful anti-inflammatory drug, inhibits such resistant cells.

New study will help investigate innate immune responses to viral infections

Researchers from Boston University School of Medicine (BUSM) report the formation of human cells containing a green fluorescent protein or GFP (one of the most important proteins in biology and fluorescence imaging) genetically fused with two interferon stimulated genes (ISGs), namely Viperin and ISG15.
