Herein, a novel dual-microRNA (dual-miRNA)-mediated 1:N-amplified DDS is fabricated.

KDM2A plays a dual role in regulating the expression of malignancy-related genes in esophageal squamous cell carcinoma.

We report that KDM2A performs an oncogenic function in esophageal squamous cell carcinoma (ESCC) and is robustly expressed in ESCC cells.
