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 method for scDNA sequencing provides insights into breast cancer evolution

vercoming previous technical challenges with single-cell DNA (scDNA) sequencing, a group led by researchers at The University of Texas MD Anderson Cancer Center has developed a novel method for scDNA sequencing at single-molecule resolution.

Researchers examine acriflavine's antiviral potential against SARS-CoV-2

Acriflavine is traditionally employed as a topical antiseptic, though has more recently been implicated as an antiviral agent at low doses, potentially by stimulating the production of interferon. In a new study recently uploaded to the bioRxiv* preprint server, the application of the drug to SARS-CoV-2 infection is investigated, demonstrating a broad activity towards a range of other betacoronaviruses.

Sargramostim drug can also improve memory in people with mild-to-moderate Alzheimer's disease

A new study suggests that Sargramostim, a medication often used to boost white blood cells after cancer treatments, is also effective in treating and improving memory in people with mild-to-moderate Alzheimer's disease.

Researchers discover a gene mutation linked to schizophrenia

Researchers at The Feinstein Institutes for Medical Research, in collaboration with Columbia University, have identified a gene mutation that could result in schizophrenia, a chronic brain disorder that affects nearly one percent of the world’s population. T

New technique traces genetic and epigenetic origins of DNA to reveal hidden cancers

A new technique that can trace which tissues and organs the DNA in our blood comes from has been reported today in the open-access eLife journal.

Pilot study finds Bartonella infection in the blood of people with schizophrenia

A pilot study from North Carolina State University and the University of North Carolina at Chapel Hill has found evidence of Bartonella infection in the blood of people with schizophrenia and schizoaffective disorder.

Genetic study identifies sex-dependent differences in major psychiatric disorders

An analysis of sex differences in the genetics of schizophrenia, bipolar disorder and major depressive disorders indicates that while there is substantial genetic overlap between males and females, there are noticeable sex-dependent differences in how genes related to the central nervous system, immune system, and blood vessels affect people with these disorders.

Gene responsible for cholesterol dysregulation in brain cancer cells could be a target for future drugs

Most people relate cholesterol to heart health, but it is also a critical component in the growth and spread of brain cancer.

Over-expression of LRRN4CL gene linked to metastasis of certain cancers to the lungs

A gene not previously linked to cancer has been shown to play a key role in the spread of certain cancers to the lungs, new research from scientists at the Wellcome Sanger Institute has shown.

New technique may result in earlier and easier identification of patients with Barrett's esophagus

A new technique for sampling and testing cells from Barrett's esophagus (BE) patients could result in earlier and easier identification of patients whose disease has progressed toward cancer or whose disease is at high risk of progressing toward cancer, according to a collaborative study by investigators at Case Western Reserve University and Johns Hopkins Kimmel Cancer Center (JHKCC).

Highly sensitive DNA nanosensor can accurately detect lethal superbugs

The persistent overuse of antibiotics has led to the evolution of antibiotic resistant pathogens, or “superbugs,” which can cause severe life-threatening infections that must be diagnosed and treated early on.

Study may help develop effective biosensors for non-invasive diagnosis of prostate cancer

The efficacy of biosensors used in clinical tests depends critically on the surface of the device on which the biorecognition molecules are immobilized.

Researchers test novel gene regulation approach to treat brain diseases

Researchers at the DZNE (Germany), at Massachusetts General Hospital (USA) and at the genomic medicine company Sangamo Therapeutics, Inc. tested a novel gene regulation approach to treat brain diseases such as Alzheimer's in laboratory studies.

Chaotic genetic changes drive the growth of melanomas

Melbourne researchers have revealed how melanoma cells are flooded with DNA changes as this skin cancer progresses from early, treatable stages through to fatal end-stage disease.

Ubiquitous microplastics can become 'hubs' for antibiotic-resistant bacteria

It's estimated that an average-sized wastewater treatment plant serving roughly 400,000 residents will discharge up to 2,000,000 microplastic particles into the environment each day.

Blocking folate metabolism could reduce SARS-CoV-2 viral replication in infected cells

The novel beta-coronavirus virus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and coronaviruses, in general, alter the host's cellular metabolism to support massive production of ~30 kB viral genomes and subgenomic viral RNAs. However, how this is achieved is largely unknown.

Genetic engineering strategy dramatically reduces tau levels in Alzheimer's animal model

Researchers have used a genetic engineering strategy to dramatically reduce levels of tau--a key protein that accumulates and becomes tangled in the brain during the development of Alzheimer's disease--in an animal model of the condition.

Acute exposure of lung tissue to vape aerosol has lesser impact on gene expression than cigarette smoke

A new peer-reviewed study published in the journal Toxicological Research & Application shows acute exposure of a 3D human bronchial tissue model to e-cigarette aerosol has minimal impact on gene expression compared to smoke from combustible cigarettes.

Study maps structure and mechanism of a membrane enzyme that plays role in inflammation, cancer

Most drugs operate via the membranes that surround the body's cells. A study by researchers at Karolinska Institutet in Sweden has now mapped the structure and mechanism of MGST2, a membrane enzyme that, amongst other things, plays a part in chronic inflammation and cancer.
