Discovery of new angiogenesis protein - possible cancer drug target

To grow and spread, tumors need new blood vessels, a process called angiogenesis. One growth factor that causes angiogenesis has been identified - vascular endothelial growth factor or VEGF - and drugs to inhibit VEGF are already in use. But not all tumors respond to the therapy initially or over the long term. Thus new growth factors need to be identified to aid in developing the next generation of angiogenesis inhibitors.

Stopping type 1 diabetes damage with vitamin C

Researchers at the Harold Hamm Oklahoma Diabetes Center have found a way to stop the damage caused by Type 1 diabetes with the combination of insulin and a common vitamin found in most medicine cabinets.

Discovery of novel mechanism controlling tumor growth in the brain

As survival rates among some patients with cancer continue to rise, so does the spread of these cancers to the brain - as much as 40 percent of all diagnosed brain cancers are considered metastatic, having spread from a primary cancer elsewhere in the body.

Gene activity reveals dynamic stroma microenvironment in prostate cancer

As stroma - the supportive framework of the prostate gland - react to prostate cancer, changes in the expression of genes occur that induce the formation of new structures such as blood vessels, nerves and parts of nerves, said researchers at Baylor College of Medicine in a report that appears in the current issue of the journal Clinical Cancer Research.

New imaging technique: toward spinal cord regeneration?

The axon is a part of the neuron through which nerve impulses are transmitted, and at the end of which is located the synapse, which connects it to another neuron. In the event of a lesion, the axon is the component which must be regenerated in order to restore the connections between the different neurons and re-form the nerve.

Eyes provide clues to a common cause of stroke

In a groundbreaking study researchers have concluded that evidence of the cause of "lacunar stroke" can be found by looking at the back of a patient's eyes.

Stopping fatty change in heart cells

Heart failure is one of the world's most frequent causes of death - caused by conditions such as diabetes and obesity. With people who are overweight, the heart has to do more work in order to pump the blood through the circulatory system and this causes an increase in blood pressure.

Model for new generation of blood vessels challenged

In-growth and new generation of blood vessels, which must take place if a wound is to heal or a tumor is to grow, have been thought to occur through a branching and further growth of a vessel against a chemical gradient of growth factors. Now a research team at Uppsala University and its University Hospital has shown that mechanical forces are considerably more important than was previously thought.

Carbon monoxide reverses gastroparesis in mice

Mayo Clinic researchers have shown that very low doses of inhaled carbon monoxide in diabetic mice reverses the condition known as gastroparesis or delayed stomach emptying, a common and painful complication for many diabetic patients. The findings will be presented on June 1 at Digestive Disease Week in Chicago.

Vandetanib shows clinical benefit when combined with docetaxel for lung cancer

When combined with standard chemotherapy, an international Phase III trial has shown that the oral targeted therapy vandetanib improves progression-free survival for patients with advanced non-small cell lung cancer, according to research from The University of Texas M. D. Anderson Cancer Center.

Lower levels of PHD2 protein influence tumor growth in mice

Tumors need a healthy supply of blood to grow and spread. Researchers at the Stanford University School of Medicine have identified a molecule that regulates blood vessel growth that is often found at less-than-normal levels in human tumors. Blocking the expression of the molecule, called PHD2, allows human cancer cells to grow more quickly when implanted into mice and increases the number of blood vessels feeding the tumor.

New credit card-sized device detects heart disease using less than one drop of blood

Testing people for heart disease might be just a finger prick away thanks to a new credit card-sized device created by a team of researchers from Harvard and Northeastern universities in Boston.

Obesity and diabetes each double the risk of heart failure - patients with both conditions ‘very difficult’ to treat

The twin epidemics of obesity and type 2 diabetes will continue to fuel an explosion in heart failure, already the world's most prevalent chronic cardiovascular disease, according to John McMurray, professor of cardiology at the Western Infirmary, Glasgow, and President of the Heart Failure Association. He reported that around one-third of patients with heart failure have evidence of diabetes, and for them the outlook is very serious. For doctors, he added, effective treatment is "very difficult".

Research offers insight into why some prostate cancer returns

The majority of men who receive one of the standard treatments for localized prostate cancer - surgery or radiation therapy - have an excellent outcome.

New microscopic device reveals cause of blood clots

Australian researchers have discovered a new way that blood clots can form which might explain why current anti-clotting drugs are sometimes ineffective.

Scientists shed new light on why pancreatic cancer drugs can fail

Cancer Research UK scientists led an international team of investigators who have discovered a new mechanism that may explain why pancreatic cancer patients are often resistant to a common chemotherapy treatment called gemcitabine, according to a study published in Science.

Control of blood sugars long-term reduces risk of heart disease in diabetics

People with diabetes who maintain intensive, low blood sugar levels are significantly less likely to suffer heart attacks and coronary heart disease, new research published today in The Lancet has shown.

Aspirin and an anti-clotting drug ‘combo’ reduces risk of dialysis access failure

For the first time, a combination of aspirin and the anti-platelet drug dipyridamole has been shown to significantly reduce blockages and extend the useful life of new artery-vein access grafts used for hemodialysis, according to a study by the Dialysis Access Consortium (DAC).

Trial tests potential new angina treatment

As part of a multi-center clinical trial, UC San Diego Medical Center is evaluating the safety and effectiveness of a potential new way to treat angina - by injecting a protein that stimulates the growth of new oxygen-rich blood vessels directly into the heart. Angina is a debilitating form of chest pain caused by coronary artery disease that affects more than nine million Americans.
