Stem cell microenvironment reverses malignant melanoma

Northwestern University researchers have demonstrated how the microenvironments of two human embryonic stem cell (hESC) lines (federally approved) induced metastatic melanoma cells to revert to a normal, skin cell-like type with the ability to form colonies similar to hESCs.

New genes that regulate longevity

In an effort to understand the molecular mechanisms that control aging, Howard Hughes Medical Institute researchers and their colleagues have now uncovered 10 new genes that regulate longevity in yeast. The studies also suggest a new model for how aging is slowed when caloric intake is restricted.

Plant extract forskolin may lead to leukemia treatment

Scientists here have identified a new pathway in the progression of chronic myelogenous leukemia (CML). They also discovered that an extract from the root of a common ornamental plant can suppress the process.

Six gene variants predict heart muscle damage after cardiac surgery

Duke University Medical Center researchers have found that patients with six specific variants of genes involved in the body's immune response are significantly more likely to suffer damage of heart tissue after cardiac surgery.

Carvedilol may improve heart failure and help prevent sudden death

Research shows that Carvedilol, a cardiovascular drug, could be useful in reducing cardiac death in high risk patients with prior myocardial infarction and/or heart failure and also in reducing the incidence and/or preventing the occurrence of atrial fibrillation in a number of clinical situations.

Link between eating and pain relief - brain stem blocks pain to protect key behaviors

Certain behaviors, such as eating, drinking and urinating, are so crucial to survival that the brains of all vertebrates contain clusters of nerve cells that can suppress pain long enough to allow the animal to eat, drink - or pee - in peace.
