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).

Melanoma mutations result from a chemical conversion in DNA fueled by sunlight, study reports

The mutations that give rise to melanoma result from a chemical conversion in DNA fueled by sunlight -; not just a DNA copying error as previously believed, reports a study by Van Andel Institute scientists published today in Science Advances.

Large nanodiscs simulate viral entry into host cells

In a paper recently uploaded to the journal Frontiers in Biotechnology by Padmanabha Das et al. (June 12th, 2020), a method of producing significantly larger homogenous nanodiscs up to 90 nm in diameter is described, and the advantages and applications of such nanodiscs are explored: better replicating the actual curvature and membrane symmetry of a real cell membrane, and allowing much larger or multiple membrane proteins to be loaded simultaneously.

New insights on replication-stress sensitivity in breast cancer cells

Oncotarget published "Frame-shift mediated reduction of gain-of-function p53 R273H and deletion of the R273H C-terminus in breast cancer cells result in replication-stress sensitivity" which reported that these authors recently documented that gain-of-function mutant p53 R273H in triple negative breast cancer cells interacts with replicating DNA and PARP1.

Analysis of DNA tags could advance the understanding and treatment of many cancers

Cell-free DNA (cfDNA) shed into the blood was discovered in the late 1940s but with rapid advances in genomics and computational analytics in just the past few years, researchers at Georgetown Lombardi Comprehensive Cancer Center now believe that studying tags, or modifications to this type of DNA, may lead to a better understanding of how to assess, and possibly modulate, treatment approaches for cancer and other diseases.

SARS-CoV-2 interacts with unusual RNA structures in human cells

The study, published in the journal Nucleic Acids Research, demonstrated that G4 ligands, the chemical that binds with G4s, prevent this interaction. The results could pave the way for developing inhibitors of these interactions as potential antiviral compounds.

Study brings scientists one step closer to solving the mystery of aging

The human body is essentially made up of trillions of living cells. It ages as its cells age, which happens when those cells eventually stop replicating and dividing.

Artificial intelligence tool enriches a gold-mine in cancer genomics

The fragments of cancer DNA analysed by the authors of this new study originate from the human genome, the sequence of which results from millions of years of evolution, and has been shaped by "copy-paste-edit" processes and co-evolution with parasitic elements.

SARS-CoV-2 reprograms host chromatic network to induce immune dysfunction

A recent study conducted at the University of Texas Science Center, Houston, in the USA, has revealed that upon infection, SARS-CoV-2 alters the host chromatin architecture to suppress antiviral interferon-responsive genes and augment inflammatory genes. The study is currently available on the bioRxiv* preprint server.
