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).

AI study on aggressive form of cancer could improve patient outcomes

International genomics research led by the University of Leicester has used artificial intelligence (AI) to study an aggressive form of cancer, which could improve patient outcomes.

Size is the only difference between male and female brains, shows study

How different are men and women's brains? The question has been explored for decades, but a new study led by Rosalind Franklin University neuroscientist Lise Eliot is the first to coalesce this wide-ranging research into a single mega-synthesis. And the answer is: hardly at all.

DAPK3 slows tumor growth by activating fierce-sounding STING pathway

The glow of a panther's eyes in the darkness. The zig-zagging of a shark's dorsal fin above the water. Humans are always scanning the world for threats.

Scientists identify new genetic clues to treat “silent’ stroke

Scientists have identified new genetic clues in people who've had small and often apparently 'silent' strokes that are difficult to treat and a major cause of vascular dementia, according to research funded by the British Heart Foundation (BHF) and published in The Lancet Neurology.

Scientists describe the mechanisms that regulate embryonic stem cells

Scientists at the Proteomics Core Unit of the Spanish National Cancer Research Centre (CNIO), headed by Javier Muñoz, have described the mechanisms, unknown to date, involved in maintaining embryonic stem cells in the best possible state for their use in regenerative medicine.

Scientists reveal salivary gland cells as sites of COVID-19 infection

Scientists have shown that SARS-CoV-2, the virus that causes COVID-19, can infect specific cells in the salivary gland in the mouth.

Study identifies NCOA3 as a novel therapeutic target for melanoma

For the first time, activation of nuclear receptor coactivator 3 (NCOA3) has been shown to promote the development of melanoma through regulation of ultraviolet radiation (UVR) sensitivity, cell cycle progression and circumvention of the DNA damage response.

UCLA researchers receive NIH grants to identify new ways to treat pancreatic cancer

A team of researchers from the UCLA Jonsson Comprehensive Cancer Center has been awarded two research grants totaling $6 million from the National Institutes of Health to identify new ways to treat pancreatic cancer.

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.
