Molecular level insights into connection between cancer and diabetes

Developing type 2 diabetes is a lengthy process. An early sign that it has begun is high levels of insulin in the blood. As long as the insulin-producing beta cells are able to compensate for the increased demand, for example when the individual is overweight, the blood sugar levels remain normal. It is not until the capacity for insulin secretion falls below the level needed that type 2 diabetes becomes a fact. The latter stage generally goes quickly, as the stressed beta cells work themselves to death.

Researchers examine how brain recognizes color

How the brain perceives color is one of its more impressive tricks. It is able to keep a stable perception of an object's color as lighting conditions change.

Alcohol can readily decrease function of women's serotonin system

After only four years of problem drinking, a significant decrease in the function of the serotonin system in women's brains can be seen. This is the system that regulates such functions as impulse control and mood. It takes 12 years before a corresponding decrease is seen in men.

Researchers discover human genes that might contribute to ALS

Amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, is a universally fatal neurodegenerative disease. Mutations in two related proteins, TDP-43 and FUS, cause some forms of ALS. Specifically, these two proteins are RNA-binding proteins that connect to RNA to regulate the translation of proteins and other cellular functions such as RNA splicing and editing. In a new study, researchers at the Perelman School of Medicine at the University of Pennsylvania discovered additional human genes with properties similar to TDP-43 and FUS that might also contribute to ALS.

Scarring prevents precipitous decline in heart function after cardiac injury

After a heart attack, the portions of the heart damaged by a lack of oxygen become scar tissue. Researchers have long sought ways to avoid this scarring, which can harden the walls of the heart, lessen its ability to pump blood throughout the body and eventually lead to heart failure. But new research from the University of North Carolina at Chapel Hill School of Medicine shows that interrupting this process can weaken heart function even further.

Blood-based gene expression test more effective in ruling out obstructive CAD

A blood-based gene expression test was found to be more effective for ruling out obstructive coronary artery disease in stable symptomatic patients than myocardial perfusion imaging (MPI), a common test that uses a radioactive agent to evaluate the blood flow and function of the heart.

New paper shows how platelets help promote cancer metastasis

About 90 percent of cancer deaths are caused by secondary tumors, known as metastases, which spread from the original tumor site. To become mobile and break free from the original tumor, cancer cells need help from other cells in their environment. Many cells have been implicated in this process, including immune system cells and cells that form connective tissue. Another collaborator in metastasis is platelets, the blood cells whose normal function is to promote blood clotting.

International consortium develops first-in-class adiponectin receptor agonist

A compound that mimics the effects of adiponectin, a beneficial protein that is produced by fat tissue in healthy weight individuals and may exhibit protective effects against cancer, cardiovascular disease, inflammatory conditions and insulin resistance has been developed by an international consortium lead by Dr. Eva Surmacz, Associate Professor in Biology (Adjunct) and director of the Obesity and Cancer Program at the Sbarro Institute for Cancer Research and Molecular Medicine at Temple University's College of Science and Technology.

Study confirms link between CMV and mucoepidermoid carcinoma

An important new study from the Laboratory for Developmental Genetics at USC has confirmed cytomegalovirus (CMV) as a cause of the most common salivary gland cancers. CMV joins a group of fewer than 10 identified oncoviruses - cancer-causing viruses - including HPV.
