Researchers identify molecule that plays key role in aggressive thyroid cancer, other cancers

Cancer researchers at Mayo Clinic's campus in Jacksonville, Florida, have identified a molecule they say is important to survival of anaplastic thyroid carcinoma (ATC) — a lethal tumor with no effective therapies.

Bacteria's DNA can pass trait to offspring in a way similar to parents' own DNA

It's a firmly established fact straight from Biology 101: Traits such as eye color and height are passed from one generation to the next through the parents' DNA.

Neuroscientist to discuss teenage brain development at AAAS meeting in California

Teenage exploration and risk taking could be explained by dramatic changes in the brain that allow elaborate planning and are driven by the need for immediate reward, according to a University of Pittsburgh neuroscientist who will be talking about her research in a panel discussion and press briefing at the American Association for the Advancement of Science annual meeting, Feb. 13 to 16, in San Jose, Calif.

Scientists demonstrate the importance of RNA editing in melanoma development

The importance of RNA editing in melanoma has been demonstrated by scientists at The University of Texas MD Anderson Cancer Center. The study revealed that a lack of RNA editing, a process by which information inside RNA molecules is transformed, leads to tumor growth and progression through manipulation of proteins.

Researchers show how gene mutations cause common forms of cartilage tumors

Duke Medicine researchers have shown how gene mutations may cause common forms of cartilage tumors. In a study published in the Feb. 16, 2015, issue of the Proceedings of the National Academy of Sciences, Duke researchers and their colleagues revealed that mutations in the isocitrate dehydrogenase (IDH) gene contribute to the formation of benign tumors in cartilage that can be a precursor to malignancies.

Research: Complex nerve circuits first evolved in common ancestor of humans and cnidarians

New research shows that a burst of evolutionary innovation in the genes responsible for electrical communication among nerve cells in our brains occurred over 600 million years ago in a common ancestor of humans and the sea anemone.

BHB compound produced during dieting blocks part of immune system involved in inflammatory disorders

Researchers at Yale School of Medicine have found that a compound produced by the body when dieting or fasting can block a part of the immune system involved in several inflammatory disorders such as type 2 diabetes, atherosclerosis, and Alzheimer's disease.

Study shows amyloid formation may link type 2 diabetes and Alzheimer disease

The pathological process amyloidosis, in which misfolded proteins (amyloids) form insoluble fibril deposits, occurs in many diseases, including Alzheimer disease (AD) and type 2 diabetes mellitus (T2D).

Researchers describe new family of bacteria common in malaria mosquitoes

A new family of bacteria that are common in malaria mosquitoes has been described by researchers at Swedish University of Agricultural Sciences (SLU) and Uppsala University in Sweden, Justus-Liebig-Universität Giessen, Germany, and the Veterinärmedizinische Universität, Austria.

Medical practitioners rarely prescribe proper treatments for childhood diarrhea, pneumonia in rural India

Few health care providers in rural India know the correct treatments for childhood diarrhea and pneumonia - two leading killers of young children worldwide. But even when they do, they rarely prescribe them properly, according to a new Duke University study.

Wistar researchers identify new therapeutic target for aggressive form of ovarian cancer

Ovarian cancer is the deadliest of all cancers affecting the female reproductive system with very few effective treatments available. Prognosis is even worse among patients with certain subtypes of the disease. Now, researchers at The Wistar Institute have identified a new therapeutic target in a particularly aggressive form of ovarian cancer, paving the way for what could be the first effective targeted therapy of its kind for the disease.

Winter weather may cause vitamin D deficiency

Residents of snowy, northern U.S. cities are at risk of vitamin D deficiency and worse, may not even know it.

New study finds promising target for future therapies to treat breast and ovarian cancer patients

The Food and Drug Administration's recent approval of the drug olaparib for ovarian cancer patients with inherited mutations in the genes BRCA1 or BRCA2 came as welcome news to the thousands of women now eligible to receive it. A new study by Dana-Farber Cancer Institute scientists indicates that the pool of patients who can benefit from the drug is potentially much wider - and offers a ready means of identifying them.

Breath test could detect Parkinson’s

The researchers, with funding from Parkinson’s UK and the British Council, will study around 200 people and see if just by looking at their breath they can determine which have Parkinson’s.

Experts question value of current obesity treatments

Many people with obesity can lose weight for a few months, but 80%–95% regain their lost weight eventually. One explanation for this limited long-term success is that reducing caloric intake triggers several biological systems that drive us to eat high-calorie foods and gain weight.

Microbes prevent malnutrition in fruit flies - and maybe humans too

A study by scientists from the Florida campus of The Scripps Research Institute (TSRI) sheds significant new light on a surprising and critical role that microbes may play in nutritional disorders such as protein malnutrition. Using fruit flies—Drosophila melanogaster—as a simple and easily studied stand-in for humans, these new findings advance our understanding of the fundamental mechanisms underlying microbial contributions to metabolism and may point to long-term strategies to treat and prevent malnutrition in general.
