Individuals without ubiquitin ligase Nedd4L more likely to develop CF

Cystic fibrosis (CF), a chronic disease that clogs the lungs and leads to life-threatening lung infections, is caused by a genetic defect in a chloride channel called cystic fibrosis transmembrane conductase regulator.

WWP2 protein appears to play a key role in tumor survival

A protein known as WWP2 appears to play a key role in tumor survival, a research team headed by a scientist at The University of Texas MD Anderson Cancer Center reports in an advance online publication of Nature Cell Biology.

Researchers deploy new tool in study of tubulin tyrosine ligase in tumor growth

Many of the newest weapons in the war on cancer come in the form of personalized therapies that can target specific changes in an individual's tumor. By disrupting molecular processes in tumor cells, these drugs can keep the tumor from growing and spreading. At the forefront of this work are Binghamton University researchers, Susan Bane, and Susannah Gal, who are deploying a new tool in their study of an enzyme called tubulin tyrosine ligase, or TTL.

Key enzyme in non-small cell lung cancers could make standard chemotherapy more effective

Scientists at the Barbara Ann Karmanos Cancer Institute in Detroit today presented a study at the American Association for Cancer Research's 102nd Annual Meeting 2011 that identifies a key enzyme in non-small cell lung cancers that could potentially make standard chemotherapy more effective against this highly deadly disease.

New signaling pathway discovery sheds light on chronic dermatitis

A new signaling pathway, which is important for the regulation of the immune response and inflammation, was discovered by an international team of scientists led by prof Ivan Dikic from the Goethe University, Frankfurt, Germany.

NIH awards TriLink $100,000 Phase I SBIR Grant to develop Hot Start approach for Ligase Chain Reaction

TriLink BioTechnologies, Inc. was recently awarded a Phase I SBIR Grant of approximately $100,000 by the National Institutes of Health to develop a Hot Start approach for Ligase Chain Reaction (LCR). Hot Start LCR will employ chemically modified ligation components containing thermolabile protecting groups to eliminate common performance problems seen in LCR, such as false-positive signals and non-specificity.

Novel gene therapy can promote removal of amyloid plaques and prevent Alzheimer's disease

Gene therapy that boosts the ability of brain cells to gobble up toxic proteins prevents development of Alzheimer's disease in mice that are predestined to develop it, report researchers at Georgetown University Medical Center. They say the treatment - which is given just once - could potentially do the same in people at the beginning stages of the disease.

cFLIP protein makes breast cancer cells resistant to TRAIL-induced apoptosis

Researchers at the Andalusian Institute for Molecular Biology and Regenerative Medicine and the University of Granada found that cFLIP -an inhibitor of death ligand-induced apoptosis- is not only essential in breast tumor cells resistance to TRAIL treatments (a death ligand with a potent therapeutic potential against cancer), but this protein is also key to the survival of such cancer cells.

New findings provide insight into brain development

St. Jude Children's Research Hospital investigators have identified key components of a signaling pathway that controls the departure of neurons from the brain niche where they form and allows these cells to start migrating to their final destination. Defects in this system affect the architecture of the brain and are associated with epilepsy, mental retardation and perhaps malignant brain tumors.

Research on Rictor protein may provide new molecular target for cancer treatment

The discovery that a protein called Rictor plays a key role in destroying a close cousin of the AKT oncogene could provide scientists with a new molecular target for treating certain cancers, including breast cancer. Described in the September 2010 issue of the journal Molecular Cell, the study was led by scientists at Beth Israel Deaconess Medical Center (BIDMC).

Cell quality control mechanism research paves way for new understanding of neurodegenerative diseases

Scientists from The Scripps Research Institute have solved a long-standing mystery of how cells conduct "quality control" to eliminate the toxic effects of a certain kind of error in protein production. The findings may lead to a better understanding of a host of neurodegenerative diseases.

Researchers find role of Vpr protein in HIV infection

Dr. Éric A. Cohen, Director of the Human Retrovirology research unit at the Institut de recherches cliniques de Montréal (IRCM), and his team published yesterday, in the online open-access journal PLos Pathogens, the results of their most recent research on the role of the Vpr protein in HIV (human immunodeficiency virus) infection and AIDS (acquired autoimmune deficiency syndrome).

Elevation of Smurf1 may play a role in molecular basis of PAH: Study

Pulmonary arterial hypertension (PAH) is a progressive disease, marked by shortness of breath and fatigue which can be fatal if untreated. Increased pressure in the pulmonary artery and its branches is associated with dysfunctional growth control of endothelial and smooth muscle cells leading to excessive thickening of the blood vessel wall, obliteration of the lumen and right heart failure.

Four-protein complex provides new target for thwarting cancer migration, invasion

The molecular machinery that switches on a gene known to cause breast cancer to spread and invade other organs has been identified by an international team led by scientists at The University of Texas M. D. Anderson Cancer Center. The paper was published Sunday in Nature Cell Biology's advanced online publication.
