Dr. Eric Olson, chairman of molecular biology at UT Southwestern Medical Center at Dallas, has found a major mechanism to explain normal and abnormal smooth muscle growth, a finding that could help in developing therapeutics for disorders like hypertension and asthma.
Researchers at UT Southwestern Medical Center at Dallas have discovered a major mechanism to explain normal and abnormal smooth muscle growth, a finding that could help in the development of novel therapeutics for disorders like hypertension and asthma.
Their work appears in today’s issue of Nature.
Smooth muscle cells are essential for the formation and function of the cardiovascular system, as well as many internal organs such as the stomach, intestine, bladder and uterus. Abnormalities in their growth can cause a wide range of human disorders, including atherosclerosis, hypertension, asthma and leiomyosarcoma (a fatal smooth-muscle cancer). The molecular mechanisms that control smooth muscle cell growth and differentiation, however, have been poorly understood.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
