Combining mitochondrial inhibitors could improve efficacy of BRAF inhibitors in melanoma

A multi-institutional study has revealed that BRAF-positive metastatic malignant melanomas develop resistance to treatment with drugs targeting the BRAF/MEK growth pathway through a major change in metabolism.

CALHM1 channel protein releases ATP to make neural taste connections

Saying that the sense of taste is complicated is an understatement, that it is little understood, even more so. Exactly how cells transmit taste information to the brain for three out of the five primary taste types was pretty much a mystery, until now.

CALHM1 protein plays critical role in sweet, bitter and umami taste perception

Working with a multidisciplinary consortium of 19 researchers from nine institutions, Monell scientists have provided critical information to identify CALHM1, a channel in the walls of taste receptor cells, as a necessary component in the process of sweet, bitter, and umami (savory) taste perception.

Study shows triple-negative breast cancer cells missing key enzyme

A groundbreaking new study led by the University of Kentucky Markey Cancer Center's Dr. Peter Zhou found that triple-negative breast cancer cells are missing a key enzyme that other cancer cells contain - providing insight into potential therapeutic targets to treat the aggressive cancer.

Oxidative stress: the price of sucrose pain relief in neonates

Although sucrose significantly reduces the pain experienced by preterm neonates undergoing heel lance, it is associated with significant increases in adenosine triphosphate use and oxidative stress, the results of a US study indicate.

Phenformin decreases size of lung tumors and increases survival in mice

Ever since discovering a decade ago that a gene altered in lung cancer regulated an enzyme used in therapies against diabetes, Reuben Shaw has wondered if drugs originally designed to treat metabolic diseases could also work against cancer.

Mice with mitochondrial mutation live longer, have less fat

If findings of a new study in mice are any indication, it might be possible to fine-tune cellular powerhouses called mitochondria, tweaking one aspect to increase insulin sensitivity, reduce body and fat mass, and even extend life. Exploiting this target could one day lead to novel treatments for type 2 diabetes - an endocrine system disease that affects 8 percent of the U.S. population. The research also points to promising new avenues of investigation in the biology of aging.

Itch-specific nerve cells: an interview with Associate Professor Xinzhong Dong

Itch was actually defined by a German physician more than 350 years ago. His name was Samuel Hafenreffer. He defined itch as an unpleasant sensation that makes people want to scratch. You probably think this is a very simple definition but itch is really a very complex sensory modality.

Biguanide mechanism discovered

Researchers have discovered a novel mechanism by which biguanides exert their glucose-lowering effect, potentially leading to new therapeutic approaches to the treatment of diabetes and insulin resistance.

Pannexin1 channel protein critical for memory and orientation

The channel protein Pannexin1 keeps nerve cells flexible and thus the brain receptive for new knowledge. Together with colleagues from Canada and the U.S., researchers at the Ruhr-Universit-t Bochum led by the junior professor Dr. Nora Prochnow from the Department of Molecular Brain Research describe these results in PLoS ONE.

Metabolic stress can increase onset of atrial fibrillation

Researchers have found new evidence that metabolic stress can increase the onset of atrial arrhythmias, such as atrial fibrillation (AF), a common heart condition that causes an irregular and often abnormally fast heart rate.

Esperion reports positive results from ETC-1002 Phase 2 clinical trial on type 2 diabetes

Esperion Therapeutics, the leading developer of small molecule therapies for the treatment of cardiometabolic disorders, today announced positive results of a recently completed Phase 2 clinical trial of ETC-1002 in patients with type 2 diabetes with LDL-C lowering of up to 43% compared to placebo.

Seven scientists named 2013 recipients of Damon Runyon-Rachleff Innovation Award

The Damon Runyon Cancer Research Foundation announced that seven scientists with novel approaches to fighting cancer have been named 2013 recipients of the Damon Runyon-Rachleff Innovation Award.

Researchers identify protein that helps prevent obesity

University of Florida researchers and colleagues have identified a protein that, when absent, helps the body burn fat and prevents insulin resistance and obesity.

Researchers study response of living cells to artificial protein

One approach to understanding components in living organisms is to attempt to create them artificially, using principles of chemistry, engineering and genetics. A suite of powerful techniques-collectively referred to as synthetic biology-have been used to produce self-replicating molecules, artificial pathways in living systems and organisms bearing synthetic genomes.

Blocking specific protein increases vulnerability of tumors to treatment

Blocking a specific protein renders tumors more vulnerable to treatment in mice, suggesting new therapies could eventually achieve the same in humans, according to new research from Fox Chase Cancer Center to be presented at the 2012 CTRC-AACR San Antonio Breast Cancer Symposium on Friday, December 7, 2012.

Vasculitis and the metabolic syndrome frequently co-exist

The metabolic syndrome is significantly more common in patients with anti-neutrophil cytoplasmic antibody-associated vasculitis than healthy individuals, researchers have found.

New paper describes MCUR1 protein and its function

Most healthy cells rely on a complicated process to produce the fuel ATP. Knowing how ATP is produced by the cell's energy storehouse - the mitochondria -- is important for understanding a cell's normal state, as well as what happens when things go wrong, for example in cancer, cardiovascular disease, neurodegeneration, and many rare disorders of the mitochondria.

Study shows how MCUR1 protein helps regulate movement of calcium into mitochondria

A team of scientists from Temple University School of Medicine and the University of Pennsylvania has moved another step closer to solving a decades-long mystery of how the all-important flow of calcium into the cell's power source, the mitochondria, is controlled.

Heidelberg researchers uncover function of specific molecular chaperones

Clumped proteins can be dissolved with the aid of cellular repair systems - a process of critical importance for cell survival especially under conditions of stress. Heidelberg researchers have now decrypted the fundamental mechanism for dissolving protein aggregates that involves specific molecular chaperones.
