You might think building muscle is a good thing, but that's often not so in the case of blood vessels in adults. In fact, excess smooth muscle is a root problem in many vascular diseases, as it causes arteries to constrict and blood pressure to rise. Now, an in-depth analysis of arterioles in mice with pulmonary hypertension explains how those misplaced smooth muscle cells develop.

Inhibiting the formation of new blood vessels is a common strategy for treating a range of conditions such as cancer, inflammatory diseases, and age-related macular degeneration. Unfortunately, drug inefficiency, resistance, and relapse have limited the success of this approach. Now new research publishing online December 12 in the Cell Press journal Cell Metabolism reveals that targeting the metabolism of blood vessels may be a way around these shortcomings.

One way to defeat an opponent is to cut off its supply lines. Tumors are no different. The supply lines for tumors are the blood vessels that ferry oxygen and nutrients to the cells. Restricting the blood vessels that feed tumor cells can shrink the tumor. A cross-institutional international team of scientists recently discovered a new, important step of the process that grows new blood vessels, a discovery that could lead to a new way to combat cancer.

A new mechanism that regulates the way blood vessels grow and connect to each other has been discovered by an international team of researchers at Karolinska Institutet, and Heinrich Heine University Düsseldorf, Germany. The knowledge might open up new opportunities for future cancer therapy. The study is published in the scientific journal PNAS.

Researchers at Karolinska Institutet have discovered a reason why people with disorders of the thyroid gland may be more sensitive to environmental temperature. According to the study, published in the Proceedings of the National Academy of Sciences (PNAS), a previously unknown link has been found between the effects of thyroid hormone on blood vessels, and how this in turn affects body temperature.

The incidence of ischemic stroke -- the most common type of stroke caused by a clot in the blood vessels of the brain -- has declined over the past decade among non-Hispanic Whites and Mexican Americans over age 60.
