Depression Boosts Heart Disease Risk by Affecting Stress-Induced Blood Flow
In studies of identical and fraternal twins, scientists found that differences in genetic makeup may make some people with depression more vulnerable to heart disease. Depression affects coronary flow reserve, a measure of heart function, but genetic susceptibility influences which individuals with depression will be at greater risk for heart disease.

Tumors work to attract new blood vessels.
Potential Drug Kills Cancer Cells by Preventing Response to Low Oxygen

A quickly growing tumor eventually outgrows its blood supply and encounters a lack of oxygen. But low oxygen drives cancer cells to send out signals that attract new blood vessels. A chemical that stops cells from responding to low oxygen could suffocate tumors. Read more. . .

Powerful Genomics Database Creates New Clinical and Research Tool for Autism
Using federal stimulus funds from the NIH, scientists will create an international, on-line genomics database from patients with autism and other developmental disorders. Data from 50,000 to 100,000 patients a year will focus on copy number variations -- inherited or acquired differences in a person's two chromosomes due to gene deletions or duplications.
