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).

Researchers unravel mechanisms that produce individualized metabolism in leukemia

A research collaboration based in Kumamoto University (Japan) has shown that lysine-specific demethylase 1 (LSD1), an enzyme involved in gene expression, produces individualized metabolism depending on the type of acute myeloid leukemia cells.

Brain cells snap DNA strands in numerous locations to make memories

The urgency to remember a dangerous experience requires the brain to make a series of potentially dangerous moves: Neurons and other brain cells snap open their DNA in numerous locations--more than previously realized, according to a new study--to provide quick access to genetic instructions for the mechanisms of memory storage.

New method expands view into activity of single cells

Researchers have devised a way to multiply by more than ten-fold the accessible details of gene activity in individual cells. It's a big leap in the effort to understand cancer development, brain function, immunity and other biological processes driven by the complex interactions of multitudes of different cell types.

Castration of male sheep slows DNA aging

Most of us are familiar with the fact that women live longer than men. But fellas, if we told you there was one thing that could be done to increase your lifespan, would you do it?

Study examines evolution and avidity of anti-SARS-CoV-2 IgG antibodies after mRNA vaccination

New research released on the medRxiv* preprint server has measured antibody responses in 71 mRNA vaccinated adults (54 vaccinated with Pfizer and 17 vaccinated with Moderna).

Developing a face mask that can detect COVID-19

A face mask has been developed that can detect COVID-19. News-Medical spoke to the researchers behind this idea to find out more about how it works.

New genetic biobank could hold the key to preventing SIDS

A state-of-the-art genetic biobank could hold the key to preventing Sudden Infant Death Syndrome (SIDS), potentially saving the lives of hundreds of babies who die from the devastating condition each year.

A new study reveals unintended CRISPR/Cas9 editing events

A recent study by researchers from Sweden and the United Kingdom shows that CRISPR/Cas9-based genomic engineering can prompt unwanted on-target effects, and highlights the complexity of human DNA repair mechanisms in the presence of the powerful prokaryotic Cas9 nuclease. The paper is currently available on the bioRxiv* preprint server.

Researchers reveal underlying genetic pathway behind neurological dysfunction of Rett syndrome

Medical researchers led by Kyushu University have revealed a possible underlying genetic pathway behind the neurological dysfunction of Rett syndrome.

Methylglyoxal detoxification deficits can be involved in the development of schizophrenia

Methylglyoxal (MG) is a highly reactive α-ketoaldehyde formed endogenously as a byproduct of the glycolytic pathway. MG accumulates under conditions of hyperglycemia, impaired glucose metabolism, or oxidative stress.

RNA-binding proteins represent a new class of drug targets for triple-negative breast cancer

In cancer research, it's a common goal to find something about cancer cells -- some sort of molecule -- that drives their ability to survive, and determine if that molecule could be inhibited with a drug, halting tumor growth. Even better: The molecule isn't present in healthy cells, so they remain untouched by the new therapy.

New study to test the scalability of offering preventive DNA screening to young adults for cancer risk

A landmark new DNA screening study to identify cancer risk in young adults will go ahead, after Monash University researcher Associate Professor Paul Lacaze was awarded a $2.97 million Medical Research Future Fund (MRFF) grant today.

High levels of neutrophil extracellular traps found in airways of severely ill Covid-19 patients

When researchers at Lund University in Sweden performed advanced analyses of sputum from the airways of severely ill Covid-19 patients, they found high levels of neutrophil extracellular traps (NETs).

Researchers discover genetic markers that drive the timing of first sex and birth

An Oxford-led team, working with Cambridge and international scholars, has discovered hundreds of genetic markers driving two of life's most momentous milestones - the age at which people first have sex and become parents.

Flinders University trial to evaluate new blood test for personalized cancer treatment

A blood test to help guide the treatment of oesophageal, stomach and bowel cancers will be evaluated in a new Flinders University trial set to get underway.

New software tool can help identify gene regulators more efficiently

A team of scientists at the University of Illinois Chicago has developed a software tool that can help researchers more efficiently identify the regulators of genes. The system leverages a machine learning algorithm to predict which transcription factors are most likely to be active in individual cells.

Researchers identify proteins that contribute to the pathogenicity of COVID-19 virus

Researchers at Texas Biomedical Research Institute (Texas Biomed) have narrowed down the proteins enabling SARS-CoV-2 to cause disease.

Cancer cells become more aggressive when exposed to tissue stiffening

In cases of breast cancer, bone metastasis - when cancer cells spread to new sites in the bone - causes the most breast cancer-related harm and is often incurable in advanced disease. A new study by University of Arizona Health Sciences researchers found that cancer cells become more aggressive when exposed to tissue stiffening and that these changes persist over time.

New study maps evolutionary history and interrelationships of protein domains

Proteins have been quietly taking over our lives since the COVID-19 pandemic began. We've been living at the whim of the virus's so-called "spike" protein, which has mutated dozens of times to create increasingly deadly variants. But the truth is, we have always been ruled by proteins. At the cellular level, they're responsible for pretty much everything.

Reduced function of key gene may affect communication between motor neurons and muscles in ALS

Amyotrophic lateral sclerosis, or ALS, attacks nerve cells known as motor neurons in the brain and spinal cord, gradually leading to paralysis.
