Abstract
Multidrug resistance (MDR) is a major obstacle limiting the effectiveness of chemotherapy against cancer. The combination strategy of chemotherapeutic agents and siRNA targeting drug efflux has emerged as an effective cancer treatment to overcome MDR. Herein, stimuli-responsive programmable tetrahedral DNA-RNA nanocages (TDRN) have been rationally designed and developed for dynamic co-delivery of the chemotherapeutic drug doxorubicin and P-glycoprotein (P-gp) siRNA. Specifically, the sense and antisense strand sequences of the P-gp siRNA, which are programmable bricks with terminal disulfide bond conjugation, are precisely embedded in one edge of the DNA tetrahedron. TDRN provides a stimuli-responsive release element for dynamic control of functional cargo P-gp siRNA that is significantly more stable than the "tail-like" TDN nanostructures. The stable and highly rigid 3D nanostructure of the siRNA-organized TDRN nanocages demonstrated a notable improvement in the stability of RNase A and mouse serum, as well as long-term storage stability for up to 4 weeks, as evidenced by this study. These biocompatible and multifunctional TDRN nanocarriers with gold nanocluster-assisted delivery (TDRN@Dox@AuNCp) are successfully used to achieve synergistic RNAi/Chemo-therapy in vitro and in vivo. This programmable TDRN drug delivery system, which integrates RNAi therapy and chemotherapy, offers a promising approach for treating multidrug-resistant tumors.

Abstract
Aptamers are chemical antibodies possessing the capability of overcoming the limitations posed by conventional antibodies, particularly for diagnostic, therapeutic, and theranostic applications in cancer. The ease of chemical modifications or functionalization, including conjugations with nucleic acids, drug molecules, and nanoparticles, has made these aptamers to gain priorities in research. In this Mini-review, various reports on therapeutics with aptamer-functionalized nanomaterials for controlled or multistep drug release, targeted delivery, stimuli-responsive drug release, etc. are discussed. In the case of nucleic-acid-conjugated aptamers, DNA nanotrains and DNA beacons are discussed in terms of the possibility of multidrug loading for chemotherapy and gene therapy. Developments with electrochemical aptasensors and signal-enhanced immune aptasensors are also discussed. Further, the future scope of aptamer technology in cancer theranostics and the prevailing limitations are discussed.

Abstract
There is a high demand to develop chemical tools to control the property and function of RNA. Current methods mainly rely on ultraviolet light-based caging strategies, which may cause phototoxicity in live cell-based experiments. We herein report an endogenous stimulus-responsive RNA acylation approach by introducing boronate ester (BE) groups to 2'-hydroxyls through postsynthetic modification. Treatment with hydrogen peroxide (H2O2) yields a phenol derivative which undergoes a 1,6-eliminaton for the traceless release of 2'-hydroxyl. We demonstrated that the acylation of crRNA enabled conditional regulation of CRISPR/Cas13a activity for activatable detection of target RNA. We also showed that the highly specific acylation of the single RNA in 8-17 DNAzyme allowed reversible control of the catalytic activity of DNAzyme, which was further applied to the cell-selective imaging of metal ions in cancer cells. Thus, our strategy provides a simple, general, and cell-selective method to control RNA activity, affording great potential in the construction of activatable RNA sensors and pre-RNA medicines.

Abstract
Translation of mRNA into protein is one of the most fundamental processes within biological systems. Gene expression is tightly regulated both in space and time, often involving complex signaling or gene regulatory networks, as most prominently observed in embryo development. Thus, studies of gene function require tools with a matching level of external control. Light is an excellent conditional trigger as it is minimally invasive, can be easily tuned in wavelength and amplitude, and can be applied with excellent spatial and temporal resolution. To this end, modification of established oligonucleotide-based technologies with optical control elements, in the form of photocaging groups and photoswitches, has rendered these tools capable of navigating the dynamic regulatory pathways of mRNA translation in cellular and in vivo models. In this review, we discuss the different optochemical approaches used to generate photoresponsive nucleic acids that activate and deactivate gene expression and function at the translational level.

Abstract
Small interfering RNA (siRNA) can effectively silence target genes through Argonate 2 (Ago2)-induced RNA interference (RNAi). It is very important to control siRNA activity in both spatial and temporal modes. Among different masking strategies, photocaging can be used to regulate gene expression through light irradiation with spatiotemporal and dose-dependent resolution. Many different caging strategies and caging groups have been reported for light-activated siRNA gene silencing. Herein, we describe a novel caging strategy that increases the blocking effect of RISC complex formation/process through host/guest (including ligand/receptor) interactions, thereby enhancing the inhibition of caged siRNA activity until light activation. This strategy can be used as a general approach to design caged siRNAs for the photomodulation of gene silencing of exogenous and endogenous genes.
