Delivery of Mir-196c-3p with NIR-II light-triggered gel attenuates cardiomyocyte ferroptosis in cardiac ischemia-reperfusion injury
Ferroptosis plays an important role in ischemia-reperfusion (I/R)-induced cardiac injury and there are many defects in current targeted delivery of miRNAs for the treatment of ferroptosis. We herein report a unique hydrogel (Gel) that can be triggered by a near-infrared-II (NIR-II) light with deep tissue penetration and biocompatible maximum permissible exposure (MPE) value for in situ treatment after I/R. The mir-196c-3p mimic (mimics) and photothermal nanoparticles (BTN) were co-encapsulated in an injectable Gel (mimics + Gel/BTN) with NIR-II light-triggered release. Using 1064 nm light irradiation, local microenvironment photothermal-triggered on-demand noninvasive controllable delivery of miRNA was achieved, aiming to inhibit I/R-induced ferroptosis. Consequently, declined ferroptosis in cardiomyocytes and improved cardiac function, survival rate in rats was achieved through the controlled release of Gel/BTN mimics in I/R model to simultaneously inhibit ferroptosis hub genes NOX4, P53, and LOX expression.
