From Lab to Life: Kitty, Kitty, Cancer Cure?

Could our kittycats hold the key to curing cancer?

Science Daily reports:  “Scientists say house cats could help unlock better cancer treatments for humans. A massive genetic study of cat tumors reveals striking similarities to human cancer and could open new paths to treatment for both species.”

It is sad that all too often, our beloved house pets, cats and dogs, develop inoperable cancer tumors, and have to be put to sleep.

It now turns out that because cat tumors closely resemble human cancer, they may become a window on  new research directions for cures.   University of Guelph (Ontario, Canada)  scientists have now published a major study in Science:

“Dr. Geoffrey Wood, a University of Guelph pathobiology professor and co-senior author of the study, said that ” …despite domestic cats being common pets, there was very little known about the genetics of cancer in these animals,” Wood says, “until now.”

Researchers examined tumor samples from almost 500 domestic cats in five countries, searching for mutations and other genetic changes that help cancers form and grow.   Many cancers are driven by changes in certain genes that normally help control how cells grow, divide, repair damage, or die. When these genes are altered, cells can begin multiplying uncontrollably. Scientists often refer to genes that contribute directly to tumor growth as cancer driver genes.

“The most common driver gene found in cat mammary tumors was FBXW7. More than 50 percent of the tumors examined carried a mutation in this gene.   FBXW7 normally helps regulate proteins involved in cell growth and division. When the gene is damaged, some of those growth promoting proteins can accumulate, potentially helping cancer cells survive and spread.  In humans, mutations in the FBXW7 gene in breast cancer are associated with worse prognosis – paralleling the change seen in cats.”

A new approach known as The One Medicine approach emphasizes “that human and veterinary medicine can inform one another. Cancer treatments developed for humans could potentially be evaluated in cats with naturally occurring tumors, while discoveries made during feline cancer studies and clinical trials could provide clues that help shape future human research.”

That little purring kitten asleep on a pillow on your sofa? It may hold the key to saving millions of people from the scourge of cancer.
