Super suppressor: Boosting a gene that stifles tumor growth

Most of the time, cancer cells do a combination of two things: they overexpress genes that drive tumor growth and they lose normal genes that typically suppress tumors. No two tumors are exactly alike, but some combination of these two effects is usually what results in cancer. Now, for the first time, researchers have shown that it’s possible to treat cancer by delivering a gene that naturally suppresses tumors.

Researchers from Boston Children’s Hospital, Brigham and Women’s Hospital and Memorial Sloan Kettering Cancer Center combined their cancer biology and nanomaterials expertise and developed a therapeutic capable of delivering a tumor suppressor gene known as PTEN, the loss of which can allow tumors to grow unchecked.

In several preclinical models, their PTENboosting therapeutic was able to inhibit tumor growth. Their findings were published yesterday in Nature Biomedical Engineering.

My work, my life, my innovations: Bruce Zetter, PhD

Though Bruce Zetter, PhD, Charles Nowiszewski Professor of Cancer Biology in Boston Children’s Hospital’s Department of Surgery, has had a lifelong passion for science, he once toyed with an alternate career—as an actor. But he stuck with his love for science and pursued a career in academic medicine. Countless patients, students, business partners and mentees have benefitted from that decision.

Read on to sort through a few artifacts from Zetter’s work and life, and if you want to hear more from him, make plans to attend Boston Children’s Global Pediatric Innovation Summit + Awards 2015,  Nov. 9 + 10, where Zetter will be the emcee for the third year.
