Agnel Sfeir, PhD (Damon Runyon-Rachleff Innovator ‘13-‘15) and colleagues at New York University School of Medicine, New York, reported that inhibiting the action of a particular enzyme called polymerase theta, or PolQ, dramatically slows the growth of tumor cells containing BRCA1 and BRCA2 genetic mutations. This could have an impact on breast and ovarian cancers. The findings were published in the journal Nature.
