Cancer Treatment Approach Targets Resistance, Gene Drive Style

Tumors and swarms of disease-carrying insects may not seem to have much in common, until you try to destroy them. Pesticide by pesticide, or chemotherapeutic by chemotherapeutic, the very thing you’re trying to destroy evolves resistance until you’ve exhausted every available option. This commonality would hardly be worth mentioning, except that an emerging means of disease vector control—gene drive—has inspired a new anticancer approach.

Re-engineering cancerous tumors to self-destruct and kill drug-resistant cells

A team led by Penn State researchers has created a modular genetic circuit that turns cancer cells into a “Trojan horse,” causing them to self-destruct and kill nearby drug-resistant cancer cells. Tested in human cell lines and in mice as proof of concept, the circuit outsmarted a wide range of resistance.

Researchers awarded $1.5M to create stem cell predictive model

Stem cells are the building blocks of the body, according to Penn State researchers. Though similar to one another at their origins, stem cells take on unique characteristics as they mature, becoming specialized cells throughout the body — such as bone, muscle, ligament, tissue or other organ cells.

Engineers model mutations causing drug resistance

Whether it is a drug-resistant strain of bacteria, or cancer cells that no longer react to the drugs intended to kill them, diverse mutations make cells resistant to chemicals, and "second generation" approaches are needed. Now, a team of Penn State engineers may have a way to predict which mutations will occur in people, creating an easier path to create effective pharmaceuticals.
