A protein that has been known until recently as part of a complex communications network within the cell also plays a direct role in regulating sugar metabolism, according to a new study published on-line in the journal Science Signaling (February 18, 2014). Cell growth and metabolism are tightly controlled processes in our cells. When these functions are disturbed, diseases such as cancer and diabetes occur. Mohamed Soliman, a PhD candidate at the Lunenfeld Tanenbaum Research Institute at...

Scientists at Tulane University School of Medicine, led by Dr. James Antoon and Dr. Barbara Beckman, have characterized two drugs targeting sphingosine kinase (SK), an enzyme involved in cancer growth and metastasis. New treatments specifically attacking cancer cells, but not normal ones, are critical in the fight against cancer. The results, which appear in the July 2012 issue of Experimental Biology and Medicine, demonstrate the role of SK in drug resistance and therapeutic potential of SK...

Inflammation and cell stress play important roles in the death of insulin-secreting cells and are major factors in diabetes. Cell stress also plays a role in Wolfram syndrome, a rare, genetic disorder that afflicts children with many symptoms, including juvenile-onset diabetes. Now a molecule has been identified that's key to the cell stress-modulated inflammation that causes insulin cells to die, report scientists at Washington University School of Medicine in St. Louis, the University of...

Research identifies novel metabolic signaling pathway in worms that coordinates the aging response to nutrient availability There is no longer any doubt that dietary restriction (DR) extends lifespan. Many studies have shown that limiting nutrient intake extends lifespan in yeast, worms, flies and as well as postponing age-related diseases in mice. However, scientists are still puzzling over the exact mechanism of DR, convinced its secrets are the key to new therapies for diseases such as...
