Development of a cancer cells self‑activating and miR‑125a‑5p expressing poly‑pharmacological nanodrug for cancer treatment.

ABSTRACT: Cancer cells can acquire resistance to targeted therapeutic agents when the designated targets or their downstream signaling molecules develop protein conformational or activity changes. There is an increasing interest in developing poly‑pharmacologic anticancer agents to target multiple oncoproteins or signaling pathways in cancer cells. The microRNA 125a‑5p (miR‑125a‑5p) is a tumor suppressor, and its expression has frequently been downregulated in tumors. By contrast, the anti‑apoptotic molecule BIRC5/SURVIVIN is highly expressed in tumors but not in the differentiated normal tissues. In the present study, the development of a BIRC5 gene promoter‑driven, miR‑125a‑5p expressing, poly‑L‑lysine‑conjugated magnetite iron poly‑pharmacologic nanodrug (pL‑MNP‑pSur‑125a) was reported. Th
