U-M researchers devise reliable way to grow tumor cells

In a development that could lead to a deeper understanding of cancer and better early-stage treatment of the disease, University of Michigan researchers have devised a reliable way to grow a certain type of cancer cells from patients outside the body for study.

Researchers find link between ferrets and humans

Research that provides a new understanding as to why ferrets are similar to humans is set to have major implications for the development of novel drugs and treatment strategies.

Trophoblasts respond to inflammatory danger signals, find NTNU researchers

Trophoblasts, cells that form an outer layer around a fertilized egg and develop into the major part of the placenta, have now been shown to respond to inflammatory danger signals, researchers from Norwegian University of Science and Technology found in a recent study published in Journal of Reproductive Immunology December 2014.

Researchers reveal common features responsible for antibiotic resistance

Treating bacterial infections with antibiotics is becoming increasingly difficult as bacteria develop resistance not only to the antibiotics being used against them, but also to ones they have never encountered before. By analyzing genetic and phenotypic changes in antibiotic-resistant strains of E. coli, researchers at the RIKEN Quantitative Biology Center in Japan have revealed a common set of features that appear to be responsible for the development of resistance to several types of antibiotics.

Broccoli can help reduce HGPS-related defects

Children who suffer from Hutchinson-Gilford Progeria syndrome age prematurely due to a defective protein in their cells. Scientists at Technische Universität München have now identified another important pathological factor: the system responsible for removing cellular debris and for breaking down defective proteins operates at lower levels in HGPS cells than in normal cells. The researchers have succeeded in reactivating protein breakdown in HGPS cells and thus reducing disease-related defects by using a substance from broccoli.

Researchers examine why Mexican-Americans at increased risk for Type 2 diabetes

While people of Mexican ancestry are nearly twice as likely to develop Type 2 diabetes as people of European heritage, the majority of research in this area has focused on those of European origin.

Two orphan receptor proteins exert fatal double whammy effect against glioblastoma cells

Two related proteins exert a lethal double whammy effect against glioblastoma cells when activated with a small molecule, say researchers at Georgetown Lombardi Comprehensive Cancer Center.

Eight researchers to receive 2015 Leibniz Prize

The new recipients of Germany's most prestigious research funding prize have been announced. In Bonn today, the Joint Committee of the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) decided to award the 2015 Leibniz Prize to eight researchers.

Study offers insights into mechanisms of bacterial resistance to antimicrobial peptides

Antimicrobial peptides are a distinctive class of potent, broad-spectrum antibiotics produced by the body's innate immune system--the first line of defense against disease-causing microbes.

Research findings may lead to new treatment strategies for Ewing sarcoma

The genetic abnormality that drives the bone cancer Ewing sarcoma operates through two distinct processes - both activating genes that stimulate tumor growth and suppressing those that should keep cancer from developing. These findings by Massachusetts General Hospital investigators, published in the November issue of Cancer Cell, may lead to new therapies targeting these aberrant mechanisms.

Secrets of success for pioneering research revealed

The British Pharmacological Society has announced the secrets of success for pioneering research along with the outcome of its annual 'Putting UK Pharmacology on the Map' vote. The vote selects sites of special scientific interest linked to achievements in pharmacology based on a ballot of MPs, peers and senior members of the scientific community.

Sugar-based molecular microcapsule eliminates toxicity of anticancer agent

Johns Hopkins researchers have developed a sugar-based molecular microcapsule that eliminates the toxicity of an anticancer agent developed a decade ago at Johns Hopkins, called 3-bromopyruvate, or 3BrPA, in studies of mice with implants of human pancreatic cancer tissue. The encapsulated drug packed a potent anticancer punch, stopping the progression of tumors in the mice, but without the usual toxic effects.

TSRI scientists discover new method for joining complex organic molecules

Chemists at The Scripps Research Institute have invented a powerful method for joining complex organic molecules that is extraordinarily robust and can be used to make pharmaceuticals, fabrics, dyes, plastics and other materials previously inaccessible to chemists.

Tel Aviv University study throws spotlight on gene mutation responsible for premature ovarian failure

Premature ovarian failure, also known as primary ovarian insufficiency (POI), affects 1% of all women worldwide. In most cases, the exact cause of the condition, which is often associated with infertility, is difficult to determine.

Scientists discover how certain gut bacteria can protect themselves, others from antibiotics

Scientists from the Institute of Food Research and the University of East Anglia have discovered how certain gut bacteria can protect themselves and others in the gut from antibiotics.

New study identifies how SNAIL gene helps cancer cells break free from primary tumor

More than 90 percent of cancer-related deaths are caused by the spread of cancer cells from their primary tumor site to other areas of the body. A new study has identified how one important gene helps cancer cells break free from the primary tumor.

Researchers identify a single protein as root cause of multiple allergic reactions

Johns Hopkins and University of Alberta researchers have identified a single protein as the root of painful and dangerous allergic reactions to a range of medications and other substances. If a new drug can be found that targets the problematic protein, they say, it could help smooth treatment for patients with conditions ranging from prostate cancer to diabetes to HIV

Scientists produce novel class of molecules that could help combat cancer, other diseases

Promising treatments known as biologics are on the market and under development for many serious illnesses such as cancer, but some of them come with high risks, even lethal ones. Now scientists have produced a novel class of molecules that could be as effective but without the dangerous side effects.

Researchers gain new insight into how motor neurons in the brain die during ALS

Researchers look to understand the causes of amyotrophic lateral sclerosis (ALS), in the hope of finding new ways to treat the disease. A new study published online today (December 17th) in the Cell Press journal Neuron shows that a common gene mutation in ALS generates a deadly protein that may cause the damage in the brain that leads to ALS.

Bacterial biofilms may increase colon cancer risk

Researchers from Johns Hopkins have found that dense mats of interacting bacteria, called biofilms, were present in the majority of cancers and polyps, particularly those on the right side of the colon. The presence of these bacterial bunches, they say, may represent an increased risk for colon cancer and could form the basis of new diagnostic tests.
