Opening the door to new drug treatments

02.11.2005


University of Leeds biologists have made an important breakthrough in developing the drugs of the future. Their work on targeting individual genes for more effective and cheaper drug testing opens the way to treatments for a huge range of diseases including diabetes and atherosclerosis, which leads to strokes and heart attacks.



Making new pharmacological ‘tools’ to explore individual genes is an enormous challenge, but vital for public health. “Testing specific genes gives us fundamental knowledge on how we could predict and prevent disease,” said Professor David Beech. “It also plays the crucial role of confirming valid gene ‘targets’ before the pharmaceuticals industry carries out complex and expensive research and development. The problem is that tools which hit just one gene-product - or protein - are extremely rare.”

The University’s £5m integrative membrane biology centre, which opened in October, has become a hub for research on ion channels – ‘doors’ controlling the movement of ions including sodium and calcium into the body’s cells. Abnormalities in these channels cause many diseases, so they are often the focus of drugs.


Professor Beech has developed a simple method for blocking the function of these channels by targeting the E3 region, important because it is accessible to antibodies introduced from outside the cells, making it an ideal drug target. “By blocking one particular channel in this region, we can see how calcium movement through this protein impacts on vascular disease,” said Professor Beech.

Professor Beech’s findings were published in a prestigious research article in Nature Biotechnology last month. The research was funded by the Wellcome Trust and the British Heart Foundation.

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

Im Focus: Water is not the same as water

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.

From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
