Findings suggest that a prosaposin-based drug could block metastasis spread

By studying the roles two proteins, thrombospondin-1 and prosaposin, play in discouraging cancer metastasis, a trans-Atlantic research team has identified a five-amino acid fragment of prosaposin that significantly reduces metastatic spread in mouse models of prostate, breast and lung cancer.

AGA researchers to present exciting data on GI disorders at DDW 2013

Clinicians, researchers and scientists from around the world will gather for Digestive Disease Week- 2013, the largest and most prestigious gastroenterology meeting, from May 18 to 21, 2013, at the Orange County Convention Center in Orlando, FL.

New study reveals another duet played by Notch and BMP signals

A small ensemble of musicians can produce an infinite number of melodies, harmonies and rhythms. So too, do a handful of workhorse signaling pathways that interact to construct multiple structures that comprise the vertebrate body.

Kinase inhibitors: an interview with Jan Hoflack, CSO of Oncodesign

Kinase inhibitors are molecules that block the activity of kinases. Kinases are a specific class of enzymes. They are extremely important in signal transduction processes in the human body meaning that they actually regulate most of the physiological processes that take place in the body.

Mutations in Ggamma13 gene may contribute to certain forms of smell disorders in humans

Researchers at the Monell Center and collaborators have identified a protein that is critical to the ability of mammals to smell. Mice engineered to be lacking the Ggamma13 protein in their olfactory receptors were functionally anosmic - unable to smell.

Scientists create animal models by altering specific genes associated with a given disease

Whitehead Institute Founding Member Rudolf Jaenisch, who helped transform the study of genetics by creating the first transgenic mouse in 1974, is again revolutionizing how genetically altered animal models are created and perhaps even redefining what species may serve as models.

Scientists spell out pivotal role of Peli1 in mouse model of multiple sclerosis

Scientists have identified an influential link in a chain of events that leads to autoimmune inflammation of the central nervous system in a mouse model of multiple sclerosis.

EPAC2 and diabetes: an interview with Dr. Hussain, Johns Hopkins University

EPAC stands for exchange protein activated by cyclic AMP (cAMP). cAMP is an (among many) intracellular messenger molecule. cAMP is generated when certain hormones stimulate a cell by binding to their receptor, which is at the outside surface of the cell.

Researchers decode toggle switch that can stimulate fat burning

For a long time, scientists have dreamt of converting undesirable white fat cells into brown fat cells and thus simply have excess pounds melt away. Researchers at the University of Bonn have now gotten a step closer to this goal: They decoded a "toggle switch" in mice which can significantly stimulate fat burning.

UTMB researchers identify protein that can interfere with the brain's response to leptin

Ever since the appetite-regulation hormone called leptin was discovered in 1994, scientists have sought to understand the mechanisms that control its action. It was known that leptin was made by fat cells, reduced appetite and interacted with insulin , but the precise molecular details of its function -details that might enable the creation of a new treatment for obesity - remained elusive.

Investigators report that cell-permeable NLS peptide shows promise in controlling atherosclerotic disease

Atherosclerosis - sometimes called "hardening of the arteries" - is a leading cause of death and morbidity in Western countries. A cell-permeable peptide containing the NF-ĸB nuclear localization sequence (NLS) shows promise as a potential agent in controlling the development of atherosclerotic disease.

New combination therapy could help restore vision

Researchers have discovered that using two kinds of therapy in tandem may be a knockout combo against inherited disorders that cause blindness. While their study focused on man's best friend, the treatment could help restore vision in people, too.

MD Anderson scientists demonstrate new way to restore tumor suppression

Tumor suppression, the family business of the sibling genes p53, p63 and p73, is undermined from within by the split personalities of p63 and p73, which each produce protein forms that not only block the work of the other two genes but also shut down its own cancer-stifling fraternal twin.

Studies, search for genetic risk factors needed to predict individual's risk for traumatic brain injury

One of the most controversial topics in neurology today is the prevalence of serious permanent brain damage after traumatic brain injury. Long-term studies and a search for genetic risk factors are required in order to predict an individual's risk for serious permanent brain damage, according to a review article published by Sam Gandy, MD, PhD, from the Icahn School of Medicine at Mount Sinai in a special issue of Nature Reviews Neurology dedicated to TBI.

Sanford-Burnham scientists identify how enzyme PKCzeta suppresses prostate tumor formation

Scientists at Sanford-Burnham Medical Research Institute have identified how an enzyme called PKCζ suppresses prostate tumor formation. The finding, which also describes a molecular chain of events that controls cell growth and metastasis, could lead to novel ways to control disease progression.

Exosomes can transfer membrane proteins, study reveals

Important new research from UMass Medical School demonstrates how exosomes shuttle proteins from neurons to muscle cells where they take part in critical signaling mechanisms, an exciting discovery that means these tiny vehicles could one day be loaded with therapeutic agents, such as RNA interference, and directly target disease-carrying cells.

Research findings could lead to development of new drugs for gout treatment

Findings from a Loyola University Chicago Stritch School of Medicine study could lead to the development of new drugs to treat gout.

Brown fat cells protective against obesity and diabetes

Brown fat is a hot topic, pardon the pun. Brown fats cells, as opposed to white fat cells, make heat for the body, and are thought to have evolved to help mammals cope with the cold. But, their role in generating warmth might also be applied to coping with obesity and diabetes.

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.
