Copper excess in diabetes hinders our ability to make healthy blood vessels
(Medical College of Georgia at Augusta University) Scientists have evidence that in diabetes, copper can pile up inside our cells, wreaking havoc on our ability to make new blood vessels, called angiogenesis. This impaired ability occurs even as the disease makes existing blood vessel walls less flexible, more leaky and more prone to accumulate plaque deposits and scars that impede good blood flow.

Study prompts new ideas on cancers' origins
(Washington University School of Medicine) Cancer therapies often target cells that grow and divide rapidly, such as stem cells, but in studying how stomach cancers occur, researchers at Washington University School of Medicine in St. Louis found that even when the stomach isn't able to make stem cells, other cells in the stomach can begin to divide and contribute to precancerous lesions.

What does hair loss have to teach us about cancer metastasis?
(Medical University of South Carolina) Researchers at the Medical University of South Carolina have identified a signaling pathway regulating cell migration and metastasis. Unexpected hair loss in a preclinical model helped them to identify the pathway. When cells within the skin that maintain hair follicles migrate too often, hair follicle maintenance is disrupted. Researchers speculated that this pathway might also play a role in cancer cell migration. Indeed, they showed that disrupting this pathway in preclinical models increased metastasis.

Nanodiscs catch misfolding proteins red-handed
(University of Michigan) When proteins misfold, accumulate and clump around insulin-producing cells in the pancreas, they kill cells. Now, researchers, including University of Michigan biophysicists, have obtained a structural snapshot of these proteins when they are most toxic, detailing them down to the atomic level.

Erectile dysfunction is red flag for silent early cardiovascular disease
(SAGE) Despite decades long prevention and treatment efforts, cardiovascular (CV) disease continues to be the leading cause of death worldwide. Early detection of CV disease can allow for interventions to prevent heart attack and stroke, including smoking cessation, medications such as a statins, blood pressure control, weight management, exercise, and improved diet. A new study published online first today in the journal Vascular Medicine, focuses on a novel risk factor for cardiovascular disease that rarely receives attention -- erectile dysfunction.
