Cancer, maths and evolution

Shifting the cancer battleground

 A new French-Australian joint cancer laboratory is forging a new way to study cancer by joining experts from different fields including mathematics, cell biology, evolutionary biology, and behavioural ecology.

Cancer is not only a major cause of human death worldwide, but also a disease that affects all multicellular organisms. Despite this, oncology and other biological sciences such as ecology and evolution have developed in relative isolation, according to Dr Beata Ujvari from the Roles of Cancer in Ecology and Evolution International Associated Laboratory at Deakin University. 

“We know that there is a clear reciprocal interaction between malignant cells and their hosts, with malignant cells evolving in response to the organism’s defence mechanisms,” Beata says.

“Cancer also directly and indirectly impacts the physiology, immunology and behaviour of organisms. But very little is actually known of the evolutionary impact of these complex relationships. We are changing that with this type of research, which has rarely been explored before,” Beata says.

The goal is to transform the understanding of cancer, its origin, how to halt its progression, and to prevent therapeutic failures. At the same time, the role of cancer in ecosystem functioning is something that ecologists need to consider.

Researchers say that cancer’s impact on ecosystems could be significant. It can influence an individual’s competitive and dispersal abilities, susceptibility to pathogens and vulnerability to predation. In some cases, such as the facial tumour disease that afflicts Tasmanian devils, it can heavily impact a species.

The joint laboratory is a collaboration between: Dr Frederic Thomas of the Centre for Ecological and Evolutionary Cancer Research at the National Scientific Research Centre (CNRS) in France; Deakin University; and the University of Tasmania, Australia. In Australia, the team has partnered with the Tasmanian Government’s Save the Tasmanian Devil Program and Zoos Victoria.

Exploring the mystery of the oceans

Australia and Japan are both island nations with vast maritime reserves and responsibilities. Together we’re developing the science needed to understand, use, enjoy and protect our unique marine ecosystems. And we’re collaborating to solve some of the mysteries of the ocean systems that drive the world’s climate.

Attack of the giant starfish

The waters off Japan’s tropical Okinawa Islands are home to hundreds of species of coral. The reefs attract a rich diversity of life: fish, turtles, whale sharks, and… the crown-of-thorns starfish.

Five thousand kilometres to the south is the Great Barrier Reef—the world’s largest reef system and one of the richest and most diverse natural ecosystems on Earth. The Australian Government is committed to protecting the Reef and has developed a plan to 2050 to ensure the sustainability of the Reef. But the Reef has lost half its coral cover in the past 30 years and periodic plagues of crown-of-thorns are responsible for more than forty per cent of the coral loss.

Finding new drugs for malaria

New drugs may be on the way for malaria, a disease that helps push millions of people into extreme poverty, thanks to an Australian team working with a remarkable new Japanese organisation.
