Cancer Research

A team led by biochemists at the University of California, San Diego has found what could be a long-elusive mechanism through which inflammation can promote cancer. The findings may provide a new approach for developing cancer therapies.

The study, published in the January 26 issue of the journal Cell, shows that what scientists thought were two distinct processes in cells—the cells’ normal development and the cells’ response to dangers such as invading organisms—are actually linked.

A provocative new model proposed by molecular biologist John Tower of the University of Southern California may help answer an enduring scientific question: Why do women tend to live longer than men?

That tendency holds true in humans and many other mammals as well as in the much-studied fruit fly Drosophila melanogaster.

In genetic studies of Drosophila, Tower and his team have shown that genes known to increase longevity always affect male and female flies differently.

"For a long time, we only did experiments in one sex or the other, depending on what was convenient," said Tower, an associate professor of biological sciences in the USC College of Letters, Arts & Sciences who has studied the genetics of aging in Drosophila for the last two decades.
