A reliable way to replicate α-synuclein aggregation on cell membranes in Parkinson's disease patients

The accumulation of α-synuclein, a small, negatively charged protein, in neural cells, is one of the hallmarks of Parkinson's disease. It has been suggested that oligomeric α-synuclein causes membranes to become permeable, or to form channels on the outer cell membrane.

Scientists identify pathway that activates hepsin on the surface of breast tumor cells

Scientists from the University of Helsinki and from UCSF have exposed a cell pathway that breast tumor cells use to destruct local tissue neighborhood. Cancer cells may use this pathway to free themselves from mammary epithelial tissue architecture, to spread to surrounding tissues. The cell pathway, the researchers found, is a biochemical chain of events leading to activation of a protein-cleaving enzyme on the surface of the tumor cells.

Scientists identify hepsin protein's role in breast cancer

Cancers rarely are deadly unless they evolve the ability to grow beyond the tissues in which they first arise. Normally, cells -- even early-stage tumor cells -- are tethered to scaffolding that helps to restrain any destructive tendencies. But scientists from the University of Helsinki, Finland, and from UCSF have identified a cleaver-wielding protein that frees some tumor cells, allowing them to further misbehave.

UI chemists debunk misconception about amphotericin

With one simple experiment, University of Illinois chemists have debunked a widely held misconception about an often-prescribed drug.

Infectious disease-fighting drugs could be designed to block pathogen's entry into cells

New research shows that infectious disease-fighting drugs could be designed to block a pathogen's entry into cells rather than to kill the bug itself.

Researchers crack structure and function of malarial protein

A biology lab at Washington University has just cracked the structure and function of a protein that plays a key role in the life of a parasite that killed 655,000 people in 2010.

Scientists identify molecular player critical to proper working of important health proteins

Half the drugs used today target a single class of proteins - and now scientists have identified an important molecular player critical to the proper workings of those proteins critical to our health.

Tyrosine kinases play greater role in mitochondria than previously recognized

Cancer cells tend to take up more glucose than healthy cells, and researchers are increasingly interested in exploiting this tendency with drugs that target cancer cells' altered metabolism.

Potential new strategy against bacteria with multi-drug resistant organisms

Vaccines with broader reach might be made by stimulating specialized immune cells to recognize foreign cell membrane proteins that are shared across bacterial species, say researchers from Children's Hospital of Pittsburgh of UPMC and the University of Pittsburgh School of Medicine in a report published online today in Immunity.

Scientists discover mechanism by which TNFα stimulates tumor formation

An inflammation-promoting protein triggers deactivation of a tumor-suppressor that usually blocks cancer formation via the NOTCH signaling pathway, a team of researchers led by scientists at The University of Texas MD Anderson Cancer Center reports today in Molecular Cell.

Short spiral-shaped proteins can efficiently deliver DNA segments to cells

Clinical gene therapy may be one step closer, thanks to a new twist on an old class of molecules. A group of University of Illinois researchers, led by professors Jianjun Cheng and Fei Wang, have demonstrated that short spiral-shaped proteins can efficiently deliver DNA segments to cells. The team published its work in the journal Angewandte Chemie.

Scientists identify how cells reduce tissue damage from inflammation in ALI model

Researchers at the University of Illinois at Chicago College of Medicine have found in an animal model of acute lung injury a molecular mechanism that allows cells of the immune system to reduce tissue damage from inflammation.

H2S plays critical role in signaling pathway linked to Alzheimer's and Parkinson's

Something rotten never smelled so sweet. This is what members of a team of scientists at Cold Spring Harbor Laboratory (CSHL) are telling one another as they discuss a new finding they did not expect to make. They have discovered that hydrogen sulfide (H2S) - the flammable, highly toxic gas that we usually associate with the smell of rotten eggs in landfills and sewers - plays an important role in the regulation of a signaling pathway implicated in biological malfunctions linked to Alzheimer's and Parkinson's diseases, among others.

New study: Insulin signaling is altered in human pancreas

Insulin signaling is altered in the pancreas, a new study shows for the first time in humans. The errant signals disrupt both the number and quality of beta cells - the cells that produce insulin.

Increased sensitivity to low frequency vibration found in people with inherited hearing loss

People with a certain form of inherited hearing loss have increased sensitivity to low frequency vibration, according to a study by Professor Thomas Jentsch of the Leibniz-Institut f-r Molekulare Pharmakologie (FMP)/Max Delbr-ck Center for Molecular Medicine (MDC) Berlin-Buch and Professor Gary Lewin (MDC), conducted in cooperation with clinicians from Madrid, Spain and Nijmegen, the Netherlands.

Diabetes increases risk of emergency caesarean birth in women with poorly contracting uterus

Researchers at the University of Liverpool have found that the strength of uterine contractions in diabetic pregnant women is significantly weaker than in non-diabetic women, increasing the risk of emergency caesarean birth.

Ferrer introduces citicoline oral solution medical food

Ferrer Therapeutics, the U.S. subsidiary of the international pharmaceutical group, Ferrer Grupo, is introducing CerAxon- Oral Solution to the U.S. market, the first and only oral solution medical food containing citicoline, a nutrient naturally produced by the body and found in the brain.

ABCC9 gene also influences duration of sleep in humans

A collaborative European study led by LMU researchers has shown that ABCC9, a known genetic factor in heart disease and diabetes, also influences the duration of sleep in humans.

Knocking out one copy of IGF1 receptor fails to increase life span of male mice

Scientists studying longevity thought it might be good to lack a copy of a gene, called IGF1 receptor, that is important in insulin signaling. Previous studies showed invertebrates that lacked the copy lived longer, even if their bodies were less responsive to insulin, the hormone that lowers blood sugar.

Cell-penetrating or antimicrobial peptides could treat atopic eczema

Scientists have found that a strain of yeast implicated in inflammatory skin conditions, including eczema, can be killed by certain peptides and could potentially provide a new treatment for these debilitating skin conditions.
