We developed a biodegradable, oncosensitive, megamer-based delivery system for miRNA therapy. The miRNA nanotherapeutics, activatable by stepwise stimulation of acidity and reduction mimicking tumor microenvironment, efficiently improve liver-specific miR-122 expression, increasing the possibility of translational application of miR-122 therapy against liver cancer.
