5-lipoxygenase, a New Therapeutic and Diagnostic Target for Heart Disease Management
|
|
|
Heart disease remains by far the major cause of morbidity and mortality in the US and other Western countries. Effective treatments for coronary artery disease (CAD) include statins and blood pressure medications. However, therapies involving different treatment strategies are needed to enhance clinical outcomes for heart disease patients. Researchers at UCLA have identified a 5-Lipoxygenase (5L...

Professor Tobias Meyer, Joshua Jones, and Angie Hahn at Stanford have developed the first live cell biosensor-based fluorescent imaging strategy to quantitatively analyze the timing of the cell cycle phases, M, G1, S, and G2. The cell cycle is a tightly regulated cellular process and failure at critical checkpoints within often results in genetic instability and eventually, cancer. In high content...

Endocytosis is an essential process in living cells that ensures proper regulation of the surface expression of membrane receptors and enzymes. This process is generally regulated by specific sequence motif in the cytoplasmic tail of internalizing proteins. The two major internalization motifs reported are tyrosine-based and di-leucine-based signals.Prostate specific membrane antigen (PSMA), a p...

A Novel Treatment for Bone Cells that Results in Increased Bone Formation

Osteoporotic bone loss is a major cause of morbidity and mortality in the aging population. This is a result of increased bone resorption by osteoclastic cells and decreased bone formation by osteoblastic cells with age and after menopause in women. Accumulating evidence suggests that the number and activity of osteoblastic cells decrease with age, however the reason for this change is not clear...

Most other contemplated therapeutic approaches act after the virus has integrated into the host cell's DNA and may be less effective once infection is established. A therapeutic strategy would en...

Renal cell carcinoma (RCC) is a form of kidney cancer that involves malignant transformation of cells of the renal tube. It is the most common type of kidney cancer in adults. In the United States more than 32,000 new cases of RCC are diagnosed every year, and approximately 12,000 people die from the disease annually. RCC metastasizes easily, often spreading to the lungs and other organs. In case...

The cellular destruction that accompanies myocardial ischemia, infarction and reperfusion is thought to be related in large part to intracellular overload of calcium. Uncontrolled Ca++ influx, which is thought to occur through "calcium leak channels," leads to progressive metabolic and functional failure of cells, and eventually to cell death. Investigators at UCLA have uncovered a class of comp...
