A research team at CiQUS (University of Santiago de Compostela, Spain) has unveiled an innovative molecular approach that enables anticancer drugs to reach the nucleus of tumor cells, where they can exert their therapeutic effect. The study focused on doxorubicin, a widely used chemotherapy agent. Prolonged exposure to this drug often leads to the emergence of resistant cells, a major clinical challenge that this strategy successfully overcomes while preserving the drug's antitumor activity.
