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.

Study sheds new light on well-known mechanism required for immune response

A new study published in the scientific journal Proceedings of the National Academy of Sciences of the United States of America sheds new light on a well-known mechanism required for the immune response. Researchers at the IRCM, led by Tarik Möröy, PhD, identified a protein that controls the activity of the p53 tumour suppressor protein known as the "guardian of the genome".

Study links poor semen quality to higher risk of various health conditions

A study of more than 9,000 men with fertility problems has revealed a correlation between the number of different defects in a man's semen and the likelihood that the man has other health problems.

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.

Scientists seek to improve stem cell transplant outcomes using DNA sequencing, mathematical modeling

Is the human immune system similar to the weather, a seemingly random yet dynamical system that can be modeled based on past conditions to predict future states? Scientists at VCU Massey Cancer Center's award-winning Bone Marrow Transplant (BMT) Program believe it is, and they recently published several studies that support the possibility of using next-generation DNA sequencing and mathematical modeling to not only understand the variability observed in clinical outcomes of stem cell transplantation, but also to provide a theoretical framework to make transplantation a possibility for more patients who do not have a related donor.

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.

Endocrine disrupting chemicals can alter thyroid levels in pregnant women, may affect fetus

A new study led by biologist R. Thomas Zoeller of the University of Massachusetts Amherst provides "the strongest evidence to date" that endocrine disrupting chemicals such as polychlorinated biphenyls (PCB) found in flame retardant cloth, paint, adhesives and electrical transformers, can interfere with thyroid hormone action in pregnant women and may travel across the placenta to affect the fetus.

Scientists undertake multiple strategies to tame Ebola virus

The Ebola epidemic in West Africa has pushed the decades-long search for a treatment to a frenetic pace. Somewhere in the virus' deceptively simple structure is a key to taming it. To find that key, scientists are undertaking multiple strategies, some of which are being fast-tracked for human testing, according to an article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society.

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.

Study reports effective treatment approach to inhibit herpes virus infection

A multi-institutional study reports an effective treatment approach to inhibit and keep latent viruses like herpes simplex from reactivating and causing disease. The work, whose lead author is the late James Hill, PhD, LSU Health New Orleans Professor and Director of Pharmacology and Infectious Disease at the LSU Eye Center, is published in the December 3, 2014, issue of Science Translational Medicine.

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.

Organovo, Yale collaborate to develop bioprinted tissues for surgical transplantation research

Organovo Holdings, Inc., a three-dimensional biology company focused on delivering breakthrough 3D bioprinting technology, and Yale School of Medicine, Department of Surgery have formed a collaboration to develop bioprinted tissues for surgical transplantation research, made possible by a generous gift from the Methuselah Foundation.

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.

Maternal age and successful egg freezing with PGS: an interview with Dr. Santiago Munné

The leading cause of of pregnancy loss or infertility is chromosomal abnormality or imbalance, where extra genetic material is present or some is missing - what’s called aneuploidy. This imbalance leads to the inability to produce viable embryos or pregnancy.

New therapeutic targets can prevent scarring within transplanted kidneys

Kidneys donated by people born with a small variation in the code of a key gene may be more likely, once in the transplant recipient, to accumulate scar tissue that contributes to kidney failure, according to a study led by researchers at the Icahn School of Medicine at Mount Sinai and published today in the Journal of Clinical Investigation.

UT Austin researchers identify network of genes that drives alcohol dependence

Researchers at The University of Texas at Austin have identified a network of genes that appear to work together in determining alcohol dependence. The findings, which could lead to future treatments and therapies for alcoholics and possibly help doctors screen for alcoholism, are being published this week in the journal Molecular Psychiatry.

Researchers explore how to turn on the activity of paternal gene

Most genes are inherited as two working copies, one from the mother and one from the father. However, in a few instances, a gene is imprinted, which means that one copy is silenced. This is called genomic imprinting. If the active copy is mutated, then disease results, even though the silenced gene copy may be normal.
