Identification of Jelly Belly gene may lead to new drugs to combat heart disease, cancer and neurological disorders
Researchers at Oregon Health & Science University (OHSU) have identified a secreted signaling protein that regulates smooth muscle development in fruit flies. In the absence of a protein called "Jelly Belly (Jeb)," primitive smooth muscle cells fail to migrate or differentiate, according to study results published in the October 2 issue of Nature.
"Our research shows that Jelly Belly is required for the normal development of the smooth muscle that surrounds the gut in flies and we are investigating it in the arteries of mammals. It is also related to the development of heart muscle," said Joseph B. Weiss M.D., Ph.D., principal investigator and assistant professor (molecular medicine and cardiology), and Heart Research Center scientist in the OHSU School of Medicine.
Smooth muscles are involved in involuntary but essential functions, such as digestion and control of blood flow. Unlocking the genetic mechanisms controlling their embryonic development may allow scientists to understand better what triggers their abnormal growth. Human disorders that are linked to abnormal smooth muscle growth or function include high blood pressure, arteriosclerosis and congenital heart defects.

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
