Protein Attributed to Membrane Repair Identified - Mechanism May Revolutionize Therapy in Human Disease

04.12.2008
Researchers at UMDNJ-Robert Wood Johnson Medical School have identified the protein MG53, as a key initiator of membrane repair in damaged tissue.

The study, released today in Nature Cell Biology, is the first to specifically pinpoint a protein responsible for promoting cell repair.

Led by Jianjie Ma, PhD, professor of physiology and biophysics, the discovery has the potential to be used as a therapeutic mechanism to repair tissue in humans, transforming treatment for patients who suffer from severe complications of disease and aging. This work was performed in collaboration with Professor Hiroshi Takeshima at Kyoto University, Japan.

“Membrane repair and remodeling is an essential process that maintains cell integrity and mediates efficient cellular function,” said Dr. Ma. “Our research shows that the protein MG53 initiates the repair mechanism in damaged tissue. Through further study, we hope to determine if MG53 can be used as a treatment in repairing human tissue that is damaged by common health conditions, including cardiovascular disease and aging.”

According to Dr. Ma, human cells are continuously injured and naturally repaired through the life span, such as micro tears caused as muscles contract within the body during normal everyday activities. However, diseases such as diabetes, cardiovascular disorders, muscular dystrophy, and even aging compromise the method in which the body repairs its own tissues, resulting in severe damage. The identification of MG53 provides hope that scientists can create therapies to treat or even prevent this damage. Through further research, Dr. Ma will study the potential for creating therapies for burn treatment, repairing sports injuries and peripheral wounds resulting from diabetes.

The research was supported by grants from the National Institutes of Health, the Ministry of Education, Science, Sports and Culture of Japan and the American Heart Association.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
