Fig. 1: Anticancer drug-mediated assembly of siRNA-carrying DNA nanostructures for synergistically combating lung cancer.

A Schematic illustration of the metformin-induced, magnesium-free self-assembly of tile-based and DNA origami nanostructures. B Metformin (MF), an anticancer drug, embedded together with KRASG12C siRNA in DNA nanostructures, exhibited a synergistic anticancer effect both in vitro and in a xenograft mouse model of KRASG12C-mutated NSCLC. NTMFK refers to KRASG12C siRNA-loaded DNA nanotubes (tile-based) assembled with metformin.
