UC researchers study processes that cause breast cancer recurrence, spread

“The focus of this grant is understanding why some breast cancers come back after initial treatment and metastasize and others don’t,” says Waltz, the principal investigator on the study. “We identified two genes (RON and DEK) which are both found in human breast cancers. When both of these genes combined are seen in breast cancers, they are highly predictive of the cancers recurring and spreading.”

She says the teams are trying to uncover reasons these genes make breast cancer so aggressive and discover whether or not this knowledge can be used to predict which tumors are more likely to come back.

“We hope this will help us identify new vulnerabilities in these cancers — an Achilles’ heel, if you will — that can be used for the treatment of these aggressive cancers,” she says. “Our new data suggest that these genes rewire breast cancer cells to support unique energy needs of the cells by increasing cholesterol and glucose use required for tumors to grow and spread. 

“In this study, we hope to map, at high resolution at the atomic level, the unique energy network driven by these two genes, with the goal of using this information to identify key nutrients that might both predict and be used to block breast cancers from coming back or metastasizing,” Waltz added.

“This could provide new ways to identify and treat potentially aggressive breast cancers at early stages, increasing survival and improving lives.”
