Abstract
DNAzymes exhibit tremendous application potentials in the field of biosensing and gene regulation due to its unique catalytic function. However, spatiotemporally controlled regulation of DNAzyme activity remains a daunting challenge, which may cause nonspecific signal leakage or gene silencing of the catalytic systems. Here, we report a photochemical approach via modular weaving active DNAzyme into the skeleton of tetrahedral DNA nanocages (TDN) for light-triggered on-demand liberation of DNAzyme and thus conditional control of gene regulation activity. We demonstrate that the direct encoding of DNAzyme in TDN could improve the biostability of DNAzyme and ensure the delivery efficiency, comparing with the conventional surface anchoring strategy. Furthermore, the molecular weaving of the DNA nanostructures allows remote control of DNAzyme-mediated gene regulation with high spatiotemporal precision of light. In addition, we demonstrate that the approach is applicable for controlled regulation of the gene editing functions of other functional nucleic acids.

Abstract
Despite the enormous potential of DNAzyme for gene therapy, its efficacy is hampered by the limited endosomal escape capability. Here, we develop a near-infrared (NIR) light-controlled DNAzyme delivery platform to achieve enhanced gene-silencing efficacy. The nanoplatform is composed of therapeutic DNAzyme, photosensitizers (PSs) and upconversion nanoparticles (UCNPs) that can convert NIR light to visible light. The system allows NIR light-activatable generation of cytotoxic reactive oxygen species due to the energy transfer from the UCNPs to PSs, which boosts the endosomal escape of DNAzyme for an improved gene-silencing efficacy. We demonstrate that the nanocomposites represent a promising platform to integrate DNAzyme-based gene therapy with NIR light-triggered photodynamic therapy for combinational tumor treatment. This work highlights a robust approach to combat the current limitations of DNAzyme delivery systems.

Abstract
Tracking spatial and temporal dynamics of bioactive molecules such as enzymes responding to therapeutic treatment is highly important for understanding of the related functions. However, in situ molecular imaging at subcellular level during photodynamic therapy (PDT) has been hampered by the limitations of existing methods. Herein, we present a multifunctional nanoplatform (termed as UR-HAPT) that is able to simultaneously monitor subcellular dynamics of human apurinic/apyrimidinic endonuclease 1 (APE1) during the near-infrared (NIR) light-mediated PDT. UR-HAPT was constructed by the combination of an upconversion nanoparticle-based PDT design and a mitochondria-targeting strategy with an APE1-responsive DNA reporter. Benefiting from the gain-of-function approach, activatable mitochondrial accumulation of APE1 in response to the oxidative stress was observed during the NIR light-triggered, mitochondria-targeted PDT process. We envision that this nanoplatform can be applicable to screen and evaluate potential enzyme inhibitors to improve the PDT efficacy.
