Hebrew University research holds promise for development of new osteoporosis drug

05.10.2010
Researchers at the Hebrew University of Jerusalem have discovered a group of substances in the body that play a key role in controlling bone density, and on this basis they have begun development of a drug for prevention and treatment of osteoporosis and other bone disorders.

The findings of the Hebrew University researchers have just been published in the American journal PNAS (Proceedings of the National Academy of Sciences).

The research group working on the project is headed by Prof. Itai Bab of the Bone Laboratory and Prof. Raphael Mechoulam of the Institute of Drug Research at the Hebrew University, and includes post-doctoral fellow Reem Smoum and doctoral students Gary Millman, Orr Ofek, Alon Bajayo, Joseph Tam, Vardit Kram and associates from the United States.

Osteoporosis is the most widespread degenerative disease in the Western world and is expressed in the loss of bone mass and the weakening of bone structure, contributing to frequent bone fractures, disability and even death. The loss of bone mass in osteoporosis is caused by internal destruction of the bone tissue. With age, the quantity of bone tissue that is lost is greater than that which is created, which leads to the decrease in bone density.

In their current research, the researchers found that the bone cells produce a series of substances composed of fatty acids and amino acids called "acyl amides." They then analyzed their precise chemical composition, created synthetic versions of them, and examined their effect on bone cell cultures.

In experiments on mice, they discovered that one of the compounds in the group of synthetic materials, oleoyl serine, increased bone density in both healthy and osteoporotic mice. They also found that the osteoporotic mice were actually missing the oleoyl serine in their bones. These findings, say the researchers, can serve as the basis for new drugs that can both prevent bone loss and boost bone formation and in this way reverse loss of bone tissue in osteoporosis patients.

Development of such a drug has begun in the laboratories of Prof. Mechoulam and Prof. Bab. Yissum, the technology transfer company of the Hebrew University, has submitted a patent application based on their work and is seeking a commercial partner for further development.

Prof. Mechoulam expressed confidence that their work showing bone mass accumulation would lead soon to the development of an effective osteoporosis drug. Drugs in use until now have worked to prevent further bone loss or to encourage bone formation, but none of them are able to accomplish both functions together as this new formula can do, said Prof. Bab.

The researchers noted that research in this field until now has been based primarily on proteins and genetics. Now, the Hebrew University researchers say, they have opened a new approach, called "skeletal lipidomics" based on the examination of substances in the skeleton containing fatty acids and amino acids. This has great significance in understanding the regulation of metabolism in bone and in other body tissues, they say.

The research has been supported by the United States-Israel Binational Science Foundation and also by a grant from the US National Institutes of Health.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
