New study may help develop targeted therapies for controlling tissue destruction

Stroke, heart attacks and numerous other common disorders result in a massive destruction of cells and tissues called necrosis. It's a violent event: As each cell dies, its membrane ruptures, releasing substances that trigger inflammation, which in turn can cause more cellular necrosis.

Researchers identifiy elusive anti-cancer property of vitamin E

Researchers have identified an elusive anti-cancer property of vitamin E that has long been presumed to exist, but difficult to find. Many animal studies have suggested that vitamin E could prevent cancer, but human clinical trials following up on those findings have not shown the same benefits.

Researchers develop single molecule test for detecting methylated DNA

Collaborators from Mayo-Illinois Alliance for Technology Based Healthcare have developed a new, single molecule test for detecting methylated DNA. Methylation -- the addition of a methyl group of molecules to a DNA strand -- is one of the ways gene expression is regulated.

Cardiohelp assists heart by pumping blood to oxygenator in seriously ill patients

A viral infection was causing life-threatening heart failure in Loyola University Medical Center patient Michelle Rivera.

Targeting Mer receptors sensitize AML and ALL to chemotherapies

Two University of Colorado Cancer Center studies show that the protein receptor Mer is overexpressed in many leukemias, and that inhibition of this Mer receptor results in the death of leukemia cells - without affecting surrounding, healthy cells.

ECMO and mechanical CPR use can lead to unexpected survival in severe heart attack patients

The use of extracorporeal membrane oxygenation (ECMO), accompanied by mechanical CPR, in patients with massive myocardial infarctions can lead to unexpected survival. These study findings are being presented March 9 at the American College of Cardiology Scientific Sessions.

Genetic mutation that alters PIEZO1 ion channel in RBCs contributes to familial xerocytosis

A genetic mutation that alters the kinetics of an ion channel in red blood cells has been identified as the cause behind a hereditary anemia, according to a paper published this month in the Proceedings of the National Academy of Sciences by University at Buffalo scientists and colleagues.

Cell fusion studies at Johns Hopkins could lead to improved treatments for muscular dystrophy

Researchers at Johns Hopkins have established a high-efficiency cell-cell fusion system, providing a new model to study how fusion works. The scientists showed that fusion between two cells is not equal and mutual as some assumed, but, rather, is initiated and driven by one of the fusion partners. The discovery, they say, could lead to improved treatments for muscular dystrophy, since muscle regeneration relies on cell fusion to make muscle fibers that contain hundreds or even thousands of nuclei.

Melittin-loaded nanoparticles can destroy human immunodeficiency virus

Nanoparticles carrying a toxin found in bee venom can destroy human immunodeficiency virus (HIV) while leaving surrounding cells unharmed, researchers at Washington University School of Medicine in St. Louis have shown.

Boosting hypocretin could elevate both mood and alertness in humans

What makes us happy? Family? Money? Love? How about a peptide? The neurochemical changes underlying human emotions and social behavior are largely unknown. Now though, for the first time in humans, scientists at UCLA have measured the release of a specific peptide, a neurotransmitter called hypocretin, that greatly increased when subjects were happy but decreased when they were sad.

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.

CALHM1 protein controls sense of taste, finds study

In collaboration with other research institutions, a Feinstein Institute for Medical Research investigator discovered a new protein that controls the sense of taste. The findings are published in the March issue of Nature.

Study shows how fish oils help lower blood pressure via vasodilation at ion channels

Omega-3 fatty acids found in oily fish may have diverse health-promoting effects, potentially protecting the immune, nervous, and cardiovascular systems.

Researchers discover how LRRK2 mutations in familial Parkinson's damage brain cells

Researchers at Columbia University Medical Center (CUMC), with collaborators at the Albert Einstein College of Medicine of Yeshiva University, have discovered how the most common genetic mutations in familial Parkinson's disease damage brain cells.

Scientists discover key biochemical step underlying heart failure

Some 5.8 million Americans suffer from heart failure, a currently incurable disease. But scientists at Temple University School of Medicine's (TUSM) Center for Translational Medicine have discovered a key biochemical step underlying the condition that could aid the development of new drugs to treat and possibly prevent it.

Two novel radiolabeled small molecules can help detect prostate cancer

Two novel radiolabeled small molecules targeting prostate-specific membrane antigen (PSMA) have excellent potential for further development as diagnostic and therapeutic radiopharmaceuticals, according to research published this month in The Journal of Nuclear Medicine.

tRNA synthetases play unexpected and critical role in cancer metastasis

Studied for decades for their essential role in making proteins within cells, several amino acids known as tRNA synthetases were recently found to have an unexpected - and critical - additional role in cancer metastasis in a study conducted collaboratively in the labs of Karen Lounsbury, Ph.D., University of Vermont professor of pharmacology, and Christopher Francklyn, Ph.D., UVM professor of biochemistry.

Macrophages allow entry of HIV in the urethra

Having suggested in 2011 that the urethra is a novel entry site for HIV, a team from the Institut Cochin, has now confirmed this hypothesis and identified the cells and mechanisms brought into play: the immune system cells macrophages, present in the epithelium of the urethra, allow the entry of HIV. This work, published online on the website of the journal Mucosal Immunology, could make it possible to test novel HIV/AIDS prevention strategies.
