TARGETING TRASTUZUMAB-RESISTANT HER2+ BREAST CANCER WITH A HER3-TARGETTING NANOPARTICLE

摘要

Disclosed herein are methods of treating cancer in a patient, the method comprising identifying a patient who is resistant to treatment with an anti-HER2 therapy; and administering to the patient a drug delivery molecule, comprising a polypeptide molecule adapted to target and/or penetrate a type of cell; a nucleic acid molecule bound to the polypeptide sequence via electrostatic interactions; and a chemical agent non- covalently linked to the nucleic acid sequence. Also disclosed are methods of inducing apoptosis in an anti-HER2 therapy resistant HER2+ breast cancer cell, the method comprising contacting the anti-HER2 therapy resistant HER2+ breast cancer cell with the drug delivery molecule. Further disclosed herein are methods of treating cancer in a patient, the method comprising identifying a patient who is resistant to anti-HER2 therapy; and administering to the patient a therapeutically effective amount of a drug delivery molecule, comprising a polypeptide molecule adapted to target and/or penetrate a type of cell; and a sulfonated corrole molecule bound to the polypeptide sequence. Finally disclosed herein are methods of inducing apoptosis in an anti-HER2 therapy resistant HER2+ breast cancer cell, the method comprising contacting the anti-HER2 therapy resistant HER2+ breast cancer cell with a drug delivery molecule, comprising a polypeptide molecule adapted to target and/or penetrate a type of cell; and a sulfonated corrole molecule bound to the polypeptide sequence
