Natural substance in red wine binds with the KSRP regulator protein and provides for its activation
A natural substance present in red wine, resveratrol, inhibits the formation of inflammatory factors that trigger cardiovascular diseases.
This has been established by a research team at the Department of Pharmacology of the University Medical Center of Johannes Gutenberg University of Mainz (JGU) working in collaboration with researchers of the Friedrich Schiller University in Jena and the University of Vienna. Their results have recently been published in the scientific journal Nucleic Acids Research.
Despite the fact that they eat more fatty foods, the French tend to less frequently develop cardiac diseases than Germans. This so-called French Paradox is attributed to the higher consumption of red wine in France and it has already been the subject of various studies in the past. A number of research projects have actually demonstrated that the natural product resveratrol, present in red wine, has a protective effect against cardiovascular diseases. But what exactly is the reason for this?
It seems that at least part of the protective effect can be explained by the fact that resveratrol inhibits the formation of inflammatory factors, a conclusion reached by the research team of Junior Professor Andrea Pautz and Professor Hartmut Kleinert of the Mainz University Medical Center following collaboration in a joint project with Professor Oliver Werz of the Friedrich Schiller University in Jena and Professor Verena Dirsch of the University of Vienna.
In fact, the researchers discovered that the natural substance binds to the regulator protein KSRP and activates it. KSRP reduces the stability of messenger RNA (mRNA) in connection with a number of inflammatory mediators and thus inhibits their synthesis.
"We now know more precisely how resveratrol inhibits the formation of the inflammatory factors that trigger cardiovascular diseases. This is an important finding in view of the fact that more recent research has shown that cardiovascular diseases are significantly promoted by inflammatory processes in the body," said Pautz.
Cardiovascular disorders, such as myocardial infarction and strokes, frequently occur in association with chronic inflammatory diseases, such as arthritis. The natural substance resveratrol thus has major therapeutic potential, particularly when it comes to the treatment of inflammatory diseases that can cause serious damage to the cardiovascular system.

Researchers see great therapeutic potential in the natural substance resveratrol, particularly in connection with prevention of the synthesis of inflammatory factors in cardiovascular diseases.

Researchers uncover protein-based “cancer signature”

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
