Scientists suspect role of mini-chromosomes in cancers, diseases caused by gene mutations

Cancers are due to genetic aberrations in certain cells that gain the ability to divide indefinitely. This proliferation of sick cells generates tumors, which gradually invade healthy tissue. Therefore, current therapies essentially seek to destroy cancer cells to stop their proliferation. Through high-throughput genetic sequencing of glioblastoma cells, one of the most deadly brain tumors, a team of geneticists from the University of Geneva's (UNIGE) Faculty of Medicine discovered that some of these mutations are caused by supplemental extrachromosomal DNA fragments, called double minutes, which enable cancer cells to better adapt to their environment and therefore better resist to treatments meant to destroy them.

Genetics may play major role in Lou Gehrig's disease, study reveals

Genetics may play a larger role in causing Lou Gehrig's disease than previously believed, potentially accounting for more than one-third of all cases, according to one of the most comprehensive genetic studies to date of patients who suffer from the condition also known as amyotrophic lateral sclerosis, or ALS.

Researchers suggest new strategy to control cellular identity and fate

A team of scientists that included researchers from UCLA has discovered a novel mechanism of RNA regulation in embryonic stem cells. The findings are strong evidence that a specific chemical modification, or "tag," on RNA plays a key role in determining the ability of embryonic stem cells to adopt different cellular identities.

Growth genes seem different in Hunger Winter children

Individuals conceived in the severe Dutch Famine, also called the Hunger Winter, may have adjusted to this horrendous period of World War II by making adaptations to how active their DNA is. Genes involved in growth and development were differentially regulated, according to researchers at the Leiden University Medical Center, Harvard University, and Columbia University's Mailman School of Public Health.

Hormone leptin increases blood pressure that occurs with weight gain

Leptin, a hormone that regulates the amount of fat stored in the body, also drives the increase in blood pressure that occurs with weight gain, according to researchers from Monash University and the University of Cambridge.

Scientists uphold mouse model of human disease, but pinpoint vital differences in gene expression

Scientists at Penn State College of Medicine, working alongside an international team of researchers, have produced the most complete encyclopedia of functional elements in the mouse genome to date and compared it to the human genome.

TSRI scientists identify 'mechanoreceptor' protein that mediates sense of touch in mammals

A team led by biologists at The Scripps Research Institute has solved a long-standing mystery in neuroscience by identifying the "mechanoreceptor" protein that mediates the sense of touch in mammals.

Phase IIb trial shows platinum-resistant ovarian patients treated with PM1183 live longer

Zeltia announces today that its pharmaceutical division PharmaMar has data from a group of 33 randomized patients with platinum-resistant ovarian cancer demonstrating that PM1183 shows a significantly superior median overall survival compared to topotecan.

Resveratrol in red wine inhibits formation of inflammatory factors that activate cardiovascular diseases

A natural substance present in red wine, resveratrol, inhibits the formation of inflammatory factors that trigger cardiovascular diseases. This has been established by a research team at the Department of Pharmacology of the University Medical Center of Johannes Gutenberg University of Mainz working in collaboration with researchers of the Friedrich Schiller University in Jena and the University of Vienna.

New technology reveals cellular gene transcription process in detail

A new technology that reveals cellular gene transcription in greater detail has been developed by Dr. Daniel Kaufmann of the University of Montreal Hospital Research Centre and the research team he directed. "This new research tool offers us a more profound view of the immune responses that are involved in a range of diseases, such as HIV infection. At the level of gene transcription, this had been difficult, complex and costly to do with current technologies, such as microscopy," explained the University of Montreal professor.

New targeted therapy shows promise in patients with ALK-positive advanced NSCLC

An international study involving Manchester researchers has found that for previously untreated lung cancer patients with a particular genetic change, a new targeted therapy is better than standard chemotherapy.

UAB research suggests potential therapeutic target for patients with frontotemporal dementia

Drugs that boost the function of a specific type of neurotransmitter receptor may provide benefit to patients with the second most common type of dementia, according to research by scientists at the University of Alabama at Birmingham published today in the Journal of Neuroscience.

Researchers identify biochemical mechanism that could lead to 'chemo brain'

UNC School of Medicine researchers have found for the first time a biochemical mechanism that could be a cause of "chemo brain" - the neurological side effects such as memory loss, confusion, difficulty thinking, and trouble concentrating that many cancer patients experience while on chemotherapy to treat tumors in other parts of the body.

Protein that regulates the body's sleep cycle may offer cancer protection

People who work around the clock could actually be setting themselves back, according to Virginia Tech biologists.

Resveratrol in red wine may prevent cancer

Alcohol use is a major risk factor for head and neck cancer. But an article published in the November issue of the journal Advances in Experimental Medicine and Biology shows that the chemical resveratrol found in grape skins and in red wine may prevent cancer as well.

SAFit-ligands provide foundation for novel treatment of stress-related psychiatric disorders

The FK506-binding protein 51 (FKBP51) is an established risk factor for stress-related psychiatric disorders such as major depression. Drug discovery for FKBP51 has been hampered by the inability to pharmacologically differentiate against the very similar functional counterplayer FKBP52.

Elevated anxious temperament associated with neuropeptide Y receptors

Persistent anxiety is one of the most common and distressing symptoms compromising mental health. Most of the research on the neurobiology of anxiety has focused on the generation of increased anxiety, i.e., the processes that "turn on" anxiety.

Researchers find way to prevent noise-induced hearing loss

Researchers from Weill Cornell Medical College and the Gladstone Institutes have found a way to prevent noise-induced hearing loss in a mouse using a simple chemical compound that is a precursor to vitamin B3. This discovery has important implications not only for preventing hearing loss, but also potentially for treating some aging-related conditions that are linked to the same protein.

BWH researchers identify cells responsible for fibrosis

Researchers from Brigham and Women's Hospital have identified what they believe to be the cells responsible for fibrosis, the buildup of scar tissue. Fibrotic diseases, such as chronic kidney disease and failure, lung disease, heart failure and cirrhosis of the liver, are estimated to be responsible for up to 45 percent of deaths in the developed world.

Researchers identify possible prognostic biomarker in triple-negative breast cancer

"Triple-negative" breast cancer (TNBC) occurs in patients whose cells do not express receptors for estrogen, progesterone, and/or human epidermal growth factor receptor 2 (ER-/PR-/HER2-).
