Cell Glue Gives Insights Into Cancer

University of Queensland researchers have discovered an important step in how proteins glue cells together to form healthy tissues, a process that is often disturbed in diseases such as cancer and inflammation.

Professor Alpha Yap, and from UQ’s (IMB) led a team that discovered the signals that prompt proteins to build the “glue” that binds cells into tissues.

“Cells are the basic building blocks of our body,” said.

“Healthy tissues require their component cells to recognise and adhere to one another.

“This adhesion is achieved through specialised bundles of proteins whose formation is promoted by a signalling protein called Rho.

“You can think of this signal like the conductor of an orchestra, making sure that all the players work together.”

Professor Yap and his team studied Rho and discovered a network of proteins that ensure Rho is activated at the correct time.

“Many of the proteins in this network have been implicated in cancer, meaning this discovery will provide valuable insights into how healthy tissues are disturbed in disease,” Professor Yap said.

It follows the Yap laboratory’s 2010 and 2011 discoveries of how come unstuck inappropriately.

This work was financially supported by the Human Frontiers Science Program, the National Health and Medical Research Council of Australia, the Australian Research Council, and the Oncology Children’s Foundation.

Confocal microscopy was performed at the IMB’s , established with the generous support of the Australian Cancer Research Foundation.
