A hijacking of healthy cellular circuits

When they are, however, they can illuminate novel therapeutic strategies. Mischel and Bensinger's team found, for example, that both glioblastoma cell cultures derived from patients and tumors transplanted into mice were potently suppressed when both receptors were blocked at once. "This suggests that if you target both receptors," says Mischel, "you might be able to prevent drug resistance."

Though the study led by Mischel and Bensinger focuses on glioblastoma, its findings are relevant to many other cancersand not just because aberrant EGFR signaling drives the growth of many types of tumors.

The next step, Mischel says, is to test in clinical trials how targeting both receptors affects the treatment of glioblastoma. He and his colleagues also hope to work with other Ludwig researchers to explore small molecule inhibitors of PDGFRβ and to examine whether similar drug resistance mechanisms are found in other cancers as well.
