Increased Survival In Metastatic Colorectal Cancer

Increased Survival In Metastatic Colorectal Cancer
A phase III trial of 1,298 colorectal cancer patients has observed that a combination of the drugs cetuximab (Erbitux) and irinotecan showed a significant improvement in progression-free survival over just irinotecan alone, as per an international team of researchers. The Erbitux Plus Irinotecan in Colorectal Cancer (EPIC) study looked at survival in metastatic colorectal cancer patients who had already shown resistance to conventional........Go to the Colon-cancer-blog (Added on 4/17/2007 5:07:18 AM)

Gene Crucial For Nerve Cell Insulation

Gene Crucial For Nerve Cell Insulation
Scientists funded by the National Institutes of Health have discovered how a defect in a single master gene disrupts the process by which several genes interact to create myelin, a fatty coating that covers nerve cells and increases the speed and reliability of their electrical signals. The discovery has implications for understanding disorders of myelin production. These disorders can affect the peripheral nervous systemthe nerves outside........Go to the Neurology news blog (Added on 4/17/2007 5:05:08 AM)

A Pancreas Cancer Risk Model

A Pancreas Cancer Risk Model
People with a family history of pancreatic cancer now have a way to accurately predict their chance of carrying a gene for hereditary pancreatic cancer and their lifetime risk of developing the disease. Developed by Johns Hopkins Kimmel Cancer Center researchers, the novel computer software tool is designed to help genetic counselors and physicians decide who would most benefit from early screening.

Genetics, society and race

Genetics, society and race
Minority individuals are much more likely to develop and die from cancer than the general U.S. population. Prior research points to lack of health insurance, poverty, language and cultural barriers, and inadequate access to early detection services and good medical care as causes. Research reported today at the 2007 Annual Meeting of the American Association for Cancer Research (AACR) suggests that genetics, in addition to socioeconomic status,........Go to the Society medical news blog (Added on 4/15/2007 9:05:34 PM)

Liver regeneration may be simpler
The way the liver renews itself may be simpler than what researchers had been assuming. A new study, appearing in the April 13 issue of The Journal of Biological Chemistry, provides new information on the inner workings of cells from regenerating livers that could significantly affect the way physicians make livers regrow in patients with liver diseases such as cirrhosis, hepatitis, or cancer.

Protein Required For Two Neighboring Cells To Fuse

Protein Required For Two Neighboring Cells To Fuse
Working with fruit flies, researchers at Johns Hopkins have discovered a protein mandatory for two neighboring cells to fuse and become one "super cell." Most cells enjoy their singular existence, but the strength and flexibility of muscles relies on hundreds or even thousands of super cells that make large-scale motion smooth and coordinated, such as flexion of a bicep.

Key Player In Embryonic Muscle Development

Key Player In Embryonic Muscle Development
Muscle fibers are large cells that contain a number of nuclei. They begin, like all animal cells, as naive embryonic cells. These cells differentiate, producing intermediate cells called myoblasts that are now destined to become muscle. New myoblasts then seek out other myoblasts, and when they find each other, they stick together like best friends. In the final stage of muscle fiber development, the cell membranes of attached myoblasts open up........Go to the Research news blog (Added on 4/11/2007 10:27:41 PM)
