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).

Study identifies a protein in Mycobacterium tuberculosis that contributes to drug tolerance

Weill Cornell Medicine researchers have identified a protein in Mycobacterium tuberculosis (Mtb) that contributes to drug tolerance, a phenomenon that allows bacteria to survive treatment with drugs that would normally kill them.

SARS-CoV-2 inhibition mediated by cellular nucleic acid-binding protein

A recent study under review at Nature Portfolio and posted to the Research Square* preprint server depicted how cellular nucleic acid-binding protein (CNBP) inhibits severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Multi-omics identify COVID-19 severity predictors and prothrombotic signatures in patients with end-stage kidney disease

Researchers demonstrated that plasma levels of leucine-rich repeat-containing 15 are a strong indicator of the severity of COVID-19 in patients with end-stage kidney disease.

Features of SARS-CoV-2 Omicron BA.2 sublineage spike protein

Researchers assessed the traits of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron BA.2 sublineage spike (S) protein.

New method enables the structural analysis of RNA molecules

We live in a world made and run by RNA, the equally important sibling of the genetic molecule DNA. In fact, evolutionary biologists hypothesize that RNA existed and self-replicated even before the appearance of DNA and the proteins encoded by it.

Novel genetic mapping study traces links between DNA variations and blood proteins

A new genetic mapping study led by researchers at the Johns Hopkins Bloomberg School of Public Health traces links between DNA variations and thousands of blood proteins in two large and distinct populations. The results should help researchers better understand the molecular causes of diseases and identify proteins that could be targeted to treat these diseases.

New technology to make temporary genetic modifications tested in mosquitoes

Texas A&M AgriLife Research scientists have tested a technology to make temporary genetic modifications in mosquitoes. The modifications self-delete over time.

Researchers design and engineer artificial photosynthetic life-forms through endosymbiosis

Every plant, animal or other nucleus-containing cell also harbors an array of miniature "organs" that perform essential functions for the cell. In plants, for example, organelles called chloroplasts photosynthesize to generate energy for the organism.

New method increases efficiency of gene editing while minimizing DNA deletion sizes

Wake Forest Institute for Regenerative Medicine (WFIRM) scientists working on CRISPR/Cas9-mediated gene editing technology have developed a method to increase efficiency of editing while minimizing DNA deletion sizes, a key step toward developing gene editing therapies to treat genetic diseases.

The generation of SARS-CoV-2 virus-like particles in insect cells

Researchers have reported the development of a promising COVID-19 vaccine candidate which is based on SARS-CoV-2 VLPs, derived from the co-expression of the spike, membrane, and envelope structural proteins in the baculovirus expression system.

Epigenetic abnormalities in hematopoietic cells during fetal development cause idiopathic autism

An international research group led by Professor Toru Takumi (Senior Visiting Scientist, RIKEN Center for Biosystems Dynamics Research) and Researcher Chia-wen Lin at Kobe University Graduate School of Medicine has shown that idiopathic autism is caused by epigenetic abnormalities in hematopoietic cells during fetal development, which results in immune dysregulation in the brain and gut.

Studies identify two groups of first-year residents who may be at risk of developing mental health issues

The first year of medical training after medical school brings intense stress, long work hours, irregular sleep schedules, and a risk of new or worsened symptoms of depression.

Study illustrates how a protein complex controls genome organization to maintain lineage fidelity

Understanding the molecular mechanisms that specify and maintain the identities of more than 200 cell types of the human body is arguably one of the most fundamental problems in molecular and cellular biology, with critical implications for the treatment of human diseases. Central to the cell fate decision process are stem cells residing within each tissue of the body.

New workflow identifies hidden genetic connections that could improve personalized medicine for IBD

All humans carry genetic variations in their DNA, called Single Nucleotide Polymorphisms (SNPs) that can underlie susceptibility to diseases such as diabetes and cancer.

Unraveling how strigoractone hormone regulates massive gene networks controlling plant growth

As sessile organisms, plants have to continually adapt their growth and architecture to the ever-changing environment. To do so, plants have evolved distinct molecular mechanisms to sense and respond to the environment and integrate the signals from outside with endogenous developmental programs.

UrFU researchers propose the use of polyoxometallate nanoclusters as chemotherapy drug carrier

Researchers at Ural Federal University have proposed the use of polyoxometallate nanoclusters as a carrier for chemotherapy drug. It will help to deliver medications precisely to the focus of a pathological process, such as a cancerous tumor, without toxic effects on healthy cells.
