Abstract
The cationic dendrimer PAMAM was modified by chondroitin sulfate (CS) through Michael addition to construct a tumor-targeted carrier CS-PAMAM for miR-34a delivery. The introduction of CS could achieve an efficient cellular uptake and intracellular transfection of miR-34a in a CD44-dependent endocytosis manner. The miR-34a delivery could execute the anti-proliferation activity by simultaneously inducing cell apoptosis and cell cycle arrest, and also the anti-migration activity. The CS-PAMAM-mediated systemic delivery of miR-34a showed significant inhibition of tumor growth and induction of tumor apoptosis using a mice model of subcutaneously implanted tumors.
