How does breast cancer start?

Most women in Australia who have breast cancer recover.  But many then relapse years later.

Marie-Liesse Asselin-Labat wants to know why.  If she can solve this mystery, her work will open up opportunities for new drugs and treatments. Her achievements to date suggest that she is well placed to succeed.

In 2006 she was part of the Walter and Eliza Hall Institute of Medical Research team that received global attention for its discovery of breast stem cells – a significant step in understanding how breast cancer starts. Marie-Liesse built on this finding with a series of papers exploring how these cells develop and are influenced by oestrogen and other steroids.

Marie-Liesse’s achievements have won her a $20,000 L’Oréal Australia For Women in Science Fellowship which she will use to develop her career as an independent researcher and to assist in the care of her two young boys.

Raised on the west coast of France, Marie-Liesse was always interested in biology. That interest took her to a pharmacy degree at the University of Nantes.  “I realised in the course of my degree how important medical research is in creating new drugs,” she says. So she turned to research and to a PhD in molecular and cellular biology at the University Paris XI. That brought her to Australia where she was entranced by the work of the Walter and Eliza Hall Institute on breast cancer.

She joined Jane Visvader and Geoff Lindeman’s team at the Institute in 2004 and contributed to the key discovery,  published in Nature in 2006 as Generation of a functional mammary gland from a single stem cell.

Breast stem cells are critical to normal breast development, but if the breast becomes cancerous they are also likely to be at heart of the problem. And that’s been the focus of Marie-Liesse’s work. In a series of high impact papers working with mice, she has  explored how these breast stem cells develop into the wide range of cells found in a normal breast and how some cells are more likely to become aggressive cancer cells.

In March this year she was lead author of a Nature paper revealing that oestrogen and other steroids can control the function of breast stem cells.

“It’s via an indirect mechanism important in understanding how stem cells proliferate, and it could lead to new treatments and new drugs,” she says.

March was a big month for her, as she also gave birth to her second child.

Many women recover from their original cancer but then, sometimes years later, the disease starts again, but more aggressively with the cancer cells rapidly spreading from the breast and throughout the body.

“I will use the L’Oréal Fellowship to find out why breast cancer often returns. I want to understand how the cells metastasise. How do they migrate from the breast?”

“The Fellowship is a great honour and will help me maintain my life-work balance with my two boys. It will help me employ a laboratory assistant to maintain the team’s productivity. The Fellowship will also assist with childcare, and support my participation in leadership training.”

“There are basic questions we still need to answer about breast cancer,” she says. “What is the cell of origin? What causes a cell to go wrong and turn to cancer?”

“I hope that within a decade my work will have changed the outcomes for breast cancer patients, and that it will help us to understand and improve the outcomes for other kinds of cancer.”
