The image demonstrates that a spiral polypeptide developed by the Cheng research group, a synthetic protein, efficiently delivers DNA segments into cancer cells. This new material can potentially be used in clinical gene therapy to improve the efficiency of gene delivery, as well as to lower toxicity in healthy tissues. These are important prerequisites for the polypeptide’s future use in cancer treatment.
