Methods: Four breast cancer cell lines, triple-negative (MDA-MB-231 and Hs578T), ER+/PR+/HER2− (MCF-7), and ER+/PR+/HER2+ (BT-474), were exposed to CHCP for 5 min at 25 V (~1675 V/cm PTEF) or 30 V (~2010 V/cm), either directly or with Plasma Activated Media (PAM). Here, ERBB2 is linked to breast carcinoma.
