Cell pathway identified which plays critical role in colon cancer

For the one in 18 men and women who will be diagnosed with cancer of the colon and rectum during their lifetime and over 150,000 people diagnosed on a yearly basis, today's genetic research news offers some optimism.

Researchers create roadmap to integrin activation

Calling it an important technical advance in the study of the complex receptors and pathways of the body's cellular system, researchers at the University of California, San Diego (UCSD) School of Medicine have reconstructed the signaling pathways that impact activation of a receptor that is critical to the control of bleeding and to the thrombosis that occurs in heart attacks and strokes.

New findings support Rapamycin's role as cancer treatment

Scientists have long known that the blood vessels of tumors differ markedly from normal blood vessels.

Genetics is a very strong component of obesity

Nearly 6 percent of morbidly obese children and adults have a genetic defect that keeps them feeling like their stomach is running on empty, no matter how much they have eaten.

Protein CD86 raises antibody output

Cancer immunologists here have discovered how a protein on the surface of antibody-making immune cells boosts the amount of antibody the cells make.

Genetics researchers identify second gene that gives rise to Alagille syndrome

In a finding that may have broader implications for understanding kidney disorders, genetics researchers at The Children's Hospital of Philadelphia have identified a second gene that gives rise to Alagille syndrome.

Gene mutation potentially involved in breast cancer initiation

Researchers have found evidence suggesting that a mutation in a gene that normally helps block the formation of breast tumors could play a role in the initiation of a major form of breast cancer.

Experimental treatment increases response rates in advanced lung cancer

An early phase study pairing an experimental targeted therapy with a common anti-inflammatory produced promising results in patients with advanced lung cancer, researchers at UCLA's Jonsson Cancer Center reported.

Signaling pathway mTOR plays a role in the brain's ability to sense how much energy the body has available

A cell-signaling pathway in the brain that is linked to the development of cancer and diabetes is also a key part of networks that regulate food intake, say University of Cincinnati (UC) researchers.

c-myc gene found to play role in immune system

c-myc, a gene commonly involved in cancer onset, has been found to have a role in the immune system's normal function according to a study published in Blood.

Penn researchers discover gene that creates "second skeleton" bone disorder

Researchers at the University of Pennsylvania School of Medicine have located the "skeleton key," a gene that, when damaged, causes the body's skeletal muscles and soft connective tissue to undergo a metamorphosis into bone, progressively locking joints in place and rendering movement impossible.

St. Jude develop strategy to speed future development of more effective and less toxic treatments for medulloblastoma

Investigators at St. Jude Children’s Research Hospital have developed a strategy to speed future development of more effective and less toxic treatments for medulloblastoma, a type of brain cancer. Medulloblastomas arise in the back of the brain and account for about 20 percent of childhood brain tumors.

Starvation activates MAP Kinase through the muscarinic acetylcholine pathway in Caenorhabditis elegans pharynx

New evidence in Cell Metabolism reveals a molecular mechanism that may play a general role in animals' ability to respond appropriately when starved.

Regular use of COX-2 inhibitors may reduce the risk of breast cancer

Results from a new, five-year study show that regular use of popular prescription pain relievers may reduce the risk of breast cancer by up to 71 percent and may offer similar benefit in the prevention of prostate, colon and lung cancers.

Dysregulation of the Hedgehog pathway in human hepatocarcinogenesis

The unchecked activity of a cell signaling pathway crucial in embryonic development and the liver's response to injury leads to liver cancer, researchers from Duke University Medical Center and John Hopkins University School of Medicine have found.

Divergent behavioral roles of angiotensin receptor intracellular signaling cascades

Researchers at the University at Buffalo and the University of Pennsylvania were the first to demonstrate that two intracellular events, both stimulated by the same cell receptor, can provoke different behaviors in mammals.

Scientists exploit novel route to reverse enlarged hearts in obese mice

Working on genetically engineered obese mice with seriously thickened hearts, a condition call cardiac hypertrophy, scientists at Johns Hopkins have used a nerve protection and growth factor on the heart to mimic the activity of the brain hormone leptin, dramatically reducing the size of the heart muscle.

Smk-1 is the first known gene that regulates longevity without disrupting life-sustaining function

Within a hormone-triggered cascade of molecular signals that plays a crucial for a wide range of physiological functions, researchers for the very first time have identified a protein that functions specifically to extend lifespan and youthfulness - without disrupting fertility
