Australia - Scientists Find New Ways To Detect Cell Receptor Cross-Talk


Innovative new technology has been used to identify and profile a novel combination of proteins that may improve treatment for prostate disorders.

Innovative new technology has been used to identify and profile a novel combination of proteins that may improve treatment for prostate disorders.

Researchers from the Western Australian Institute for Medical Research (WAIMR) and The University of Western Australia (UWA), in collaboration with the Monash Institute of Pharmaceutical Sciences in Melbourne, have found novel ways to identify G protein-coupled receptor (GPCR) heteromers on the surface of cells.

The study, published in the Journal of Biological Chemistry, is based on the work by senior author Associate Professor Kevin Pfleger and colleagues.

Pfleger co-invented the technology to identify and study GPCRs, a family of receptors present on the outside of all cell membranes that enable cells to respond to hormones and neurotransmitters.

This GPCR family of receptors are extremely important in treating disease and are the target of up to 50 percent of all therapeutic drugs.

“Scientists now realize that these receptors do not work in isolation, but in particular combinations, which they call ‘heteromers’,” said Pfleger.

“It is suggested that a number of side effects from drugs may result from not fully understanding which combinations form and what happens when they do.”

Pfleger, who won the 2011 Australian Museum 3M Eureka Prize for Emerging Leader in Science, said prostate disorders such as benign prostatic hyperplasia affected nearly every man at some point in his life.

Better drugs with fewer side effects were needed to reduce or eliminate the need for surgical intervention in more serious cases, he said.

“We hope that the identification of this novel combination of receptors, and the novel functioning that results from their interaction, will provide opportunities to develop better treatments for debilitating prostate disorders that affect so many aging men,” Pfleger said.

The technology described here has been assigned to the UWA spin-out company Dimerix Bioscience for commercial development.
