Coming soon: Cell therapies for diabetes, cancer? (3/24/2008)

Therapies using stem cell transplants are advancing promising treatments for such conditions as Alzheimer's Disease, neurological diseases and spinal cord injury, and heart disease. Now, scientists think that stem cell transplants may ultimately benefit those who suffer from diabetes or cancer. However, important questions need answers: Given the shortage of human pancreatic islet tissue, can stem cells be used to provide insulin cells that can be stored and secreted from a bioartifical pancreas? Can islet cells be frozen for long periods of time, retain their integrity and be transplanted? If tumors contain cancer stem cells, how can the stem cells be targeted and destroyed to provide improved therapies? ...> Full Article

Researchers unmask proteins in telomerase, a substance that enables cancer (3/22/2008)

One of the more intriguing workhorses of the cell, a protein conglomerate called telomerase, has in its short history been implicated in some critical areas of medicine including cancer, aging and keeping stem cells healthy. With such a resume, telomerase has been the subject of avid interest by basic scientists and pharmaceutical companies alike, so you'd think at the very least people would know what it is. ...> Full Article

Blood disorder protects against severe malarial anaemia (3/21/2008)

Researchers have moved a step closer to understanding why alpha-thalassaemia, an inherited blood disorder, appears to offer protection against severe malarial anaemia. The key appears to be in the abnormally large number of small red blood cells which characterises thalassaemia. ...> Full Article

New Method Selects Eggs With Best Chance Of Leading To Successful Pregnancy (3/19/2008)

A research team supervised by Université Laval scientist Marc-André Sirard has identified genetic markers that allow the selection of eggs with the best chance of leading to successful pregnancy after in vitro fertilization (IVF). This finding could both increase the success rate of single embryo transfer and diminish the risk of multiple pregnancies. The details of the method developed by the researchers, for which an international patent application has been filed ...> Full Article

New Longevity Genes Identified: Yeast, Worms And People May Age By Similar Mechanisms (3/19/2008)

Scientists have identified 25 genes regulating lifespan in two organisms separated by about 1.5 billion years in evolutionary change. At least 15 of those genes have very similar versions in humans, suggesting that scientists may be able to target those genes to help slow down the aging process and treat age-related conditions. ...> Full Article

Modified Virus Vaccine Shows Breast Cancer Promise (3/18/2008)

Researchers have shown that vaccinating mice with a modified form of a virus containing proteins from breast cancer cells can kill large breast cancer tumors and tumors that have spread to the lungs. The rodent model of cancer used in this study closely resembles a type of breast cancer seen in humans called HER2-positive. Although other cancer vaccines have shown activity in the treatment of very small tumors, their ability to influence large, established tumors, such as many HER2-positive breast cancers, has proven difficult. The study, led by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health, appeared in the March 15, 2008, issue of Cancer Research. ...> Full Article
