Yeast provides genetic clues on drug response
These 50 major response types, known as gene signatures, are like fingerprints that identify all genes and their relevance to a specific drug treatment.
This relatively small number of gene signatures means that it might be possible to eventually use a person’s genome to predict their drug response. It could also make it easier to identify more effective therapies.
“This is a starting reference map for understanding variation in drug response,” says Guri Giaever, an associate professor in UBC’s Faculty of Pharmaceutical Sciences, and a senior author on the study, published today in Science. “It won’t be easy but our results suggest it is a solvable problem.”
Corey Nislow, also associate professor in the faculty and senior author, says this research will help us better understand how and why some drugs work and others don’t.
The findings may also be relevant to cancer treatment. Researchers identified all genes that are essential for growth when cells are chemically stressed. Because cancer is principally a cell that grows out of control, the research points to different strategies to develop new drugs that target these genes.
