Abstract
Plasmids are ubiquitous in biology, where they are used to study gene-function relationships and intricate molecular networks, and hold potential as therapeutic devices. Developing methods to control their function will advance their application in research and may also expedite their translation to clinical settings. Light is an attractive stimulus to conditionally regulate plasmid expression as it is non-invasive, and its properties such as wavelength, intensity, and duration can be adjusted to minimise cellular toxicity and increase penetration. Herein, we have developed a method to site-specifically introduce photocages into plasmids, by resynthesising one strand in a manner similar to Kunkel mutagenesis. Unlike alternative approaches to chemically modify plasmids, this method is sequence-independent at the site of modification and uses commercially available phosphoramidites. To generate our light-activated (LA) plasmids, photocleavable biotinylated nucleobases were introduced at specific sites across the T7 and CMV promoters on plasmids and bound to streptavidin to sterically block access. These LA-plasmids were then successfully used to control expression in both cell-free systems (T7 promoter) and mammalian cells (CMV promoter). These light-activated plasmids might be used to remotely control cellular activity and reduce off-target toxicity for future medical use. Our simple approach to plasmid modification might also be used to introduce novel chemical moieties for advanced function.

Abstract
Despite significant progress in DNA self-assembly for interfacing with biology, spatiotemporally controlled regulation of biological process via in situ dynamic DNA assembly remains an outstanding challenge. Here, we report an optically triggered DNA assembly and disassembly strategy that enables on-demand activation and termination of the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) signaling pathway. In the design, an activatable DNA hairpin is engineered with a photocleavable group at defined site to modulate its self-assembly activity. Light activation induces the configurational switching and consequent self-assembly of the DNA hairpins to form long linear double-stranded structures, allowing to stimulate cGAS protein to synthesize 2',3'-cyclic-GMP-AMP (cGAMP) for STING stimulation. Furthermore, by endowing the pre-assembled DNA scaffold with a built-in photolysis feature, we demonstrate that the cGAS-STING stimulation can be efficiently terminated through remote photo-triggering, providing for the first time a route to control the temporal "dose" on-demand for such a stimulation. We envision that this regulation strategy will benefit and inspire both fundamental research and therapeutic applications regarding the cGAS-STING pathway.

Abstract
Integrating light-sensitive molecules within nanoparticle (NP) assemblies is an attractive approach to fabricate new photoresponsive nanomaterials. Here, we describe the concept of photocleavable anionic glue (PAG): small trianions capable of mediating interactions between (and inducing the aggregation of) cationic NPs by means of electrostatic interactions. Exposure to light converts PAGs into dianionic products incapable of maintaining the NPs in an assembled state, resulting in light-triggered disassembly of NP aggregates. To demonstrate the proof-of-concept, we work with an organic PAG incorporating the UV-cleavable o-nitrobenzyl moiety and an inorganic PAG, the photosensitive trioxalatocobaltate(III) complex, which absorbs light across the entire visible spectrum. Both PAGs were used to prepare either amorphous NP assemblies or regular superlattices with a long-range NP order. These NP aggregates disassembled rapidly upon light exposure for a specific time, which could be tuned by the incident light wavelength or the amount of PAG used. Selective excitation of the inorganic PAG in a system combining the two PAGs results in a photodecomposition product that deactivates the organic PAG, enabling nontrivial disassembly profiles under a single type of external stimulus.

Abstract
Methyltransferases (MTases) play an important role in the functioning of living systems, catalyzing the methylation reactions of DNA, RNA, proteins, and small molecules, including endogenous compounds and drugs. Many human diseases are associated with disturbances in the functioning of these enzymes; therefore, the study of MTases is an urgent and important task. Most MTases use the cofactor S‑adenosyl‑L‑methionine (SAM) as a methyl group donor. SAM analogs are widely applicable in the study of MTases: they are used in studies of the catalytic activity of these enzymes, in identification of substrates of new MTases, and for modification of the substrates or substrate linking to MTases. In this review, new synthetic analogs of SAM and the problems that can be solved with their usage are discussed.

Abstract
Light-triggered chemical reactions can provide excellent tools to investigate the fundamental mechanisms important in biology. Light is easily applicable and orthogonal to most cellular events, and its dose and locality can be controlled in tissues and cells. Light-induced conversion of photochemical groups installed on small molecules, proteins, and oligonucleotides can alter their functional states and thus the ensuing biological events. Recently, photochemical control of DNA/RNA structure and function has garnered attention thanks to the rapidly expanding photochemistry used in diverse biological applications. Photoconvertible groups can be incorporated in the backbone, ribose, and nucleobase of an oligonucleotide to undergo various irreversible and reversible light-induced reactions such as cleavage, crosslinking, isomerization, and intramolecular cyclization reactions. In this review, we gather a list of photoconvertible groups used in oligonucleotides and summarize their reaction characteristics, impacts on DNA/RNA thermal stability and structure, as well as their biological applications.

Abstract
In this work, a DNA three-way junction (TWJ) with multiple recognition regions was intelligently engineered, which could be applied as an unconfined DNA walker with a rapid walking speed and high sensitivity for electrochemical detection of microRNA (miRNA-182-5p). Once the target miRNA was presented, the hairpins on TWJ could be successively opened to form an annular DNA walker, which could walk on the entire scope of the electrode surface without the confine for the length of DNA walker legs compared with the traditional DNA walker, greatly improving the walking efficiency. In addition, this DNA walker with multirecognition segments could obviously increase the local concentration of recognition sites, which significantly enhanced the detection speed and sensitivity. As a result, this proposed biosensor with annular DNA as a walker could dexterously achieve the ultrasensitive and fast detection of miRNA-182-5p from 0.1 fM to 1 nM with a detection limit of 31.13 aM. Meaningfully, this strategy explored an innovative path in the design of a new DNA walker nanostructure for accomplishing speedy and sensitive detection of biomarkers.

Abstract
Genome editing technology commenced in 1996 with the discovery of the first zinc-finger nuclease. Application of Clustered Regularly Interspaced Short Palindromic Repeat (CRISPR) associated protein 9 (Cas9) technology to genome editing of mammalian cells allowed researchers to use genome editing more easily and cost-effectively. However, one of the technological problems that remains to be solved is "off-target effects", which are unexpected mutations in nontarget DNA. One significant improvement in genome editing technology has been achieved with molecular/protein engineering. The key to this engineering is a "switch" to control function. In this review, we discuss recent efforts to design novel "switching" systems for precise editing using genome editing tools.

Abstract
Echinoderms are important experimental models for analyzing embryonic development, but a lack of spatial and temporal control over gene perturbations has hindered developmental studies using these animals. Morpholino antisense oligonucleotides (MOs) have been used successfully by the echinoderm research community for almost two decades, and MOs remain the most widely used tool for acute gene knockdowns in these organisms. Echinoderm embryos develop externally and are optically transparent, making them ideally-suited to many light-based approaches for analyzing and manipulating development. Studies using zebrafish embryos have demonstrated the effectiveness of photoactivatable (caged) MOs for conditional gene knockdowns. Here we show that caged MOs, synthesized using nucleobase-caged monomers, provide light-regulated control over gene expression in sea urchin embryos. Our work provides the first robust approach for conditional gene silencing in this prominent model system.

We present the synthesis of 2-nitrobenzyl photocaged 5-hydroxymethyl-2'-deoxycytidine and uridine 3'-O-phosphoramidites and their use in automated solid-phase synthesis of oligonucleotides (ONs) modified at specific positions. The ONs were used as primers for PCR to construct DNA templates modified in the promoter region that allowed switching of transcription through photochemical uncaging.

Abstract
The expression of a gene to a protein is one of the most vital biological processes. The use of light to control biology offers unparalleled spatiotemporal resolution from an external, orthogonal signal. A variety of methods have been developed that use light to control the steps of transcription and translation of specific genes into proteins, for cell-free to in vivo biotechnology applications. These methods employ techniques ranging from the modification of small molecules, nucleic acids and proteins with photocages, to the engineering of proteins involved in gene expression using naturally light-sensitive proteins. Although the majority of currently available technologies employ ultraviolet light, there has been a recent increase in the use of functionalities that work at longer wavelengths of light, to minimise cellular damage and increase tissue penetration. Here, we discuss the different chemical and biological methods employed to control gene expression, while also highlighting the central themes and the most exciting applications within this diverse field.

Abstract
We developed a new method for the conditional regulation of CRISPR/Cas9 activity in mammalian cells and zebrafish embryos using photochemically activated, caged guide RNAs (gRNAs). Caged gRNAs are generated by substituting four nucleobases evenly distributed throughout the 5'-protospacer region with caged nucleobases during synthesis. Caging confers complete suppression of gRNA:dsDNA-target hybridization and rapid restoration of CRISPR/Cas9 function upon optical activation. This tool offers simplicity and complete programmability in design, high spatiotemporal specificity in cells and zebrafish embryos, excellent off-to-on switching, and stability by preserving the ability to form Cas9:gRNA ribonucleoprotein complexes. Caged gRNAs are novel tools for the conditional control of gene editing, thereby enabling the investigation of spatiotemporally complex physiological events by obtaining a better understanding of dynamic gene regulation.

We developed new DNA triplexes that contain four base triads T-A·T, A-ψ·CBr, G-PIC·YO, and C-G·Py+, where CBr, YO, Py, ψ, and PIC are 5-bromocytosine, 5-methyl-4-pyrimidone, 2-aminopyridine, the aglycons of deoxypseudouridine, and deoxypseudoisocytidine, respectively. DNA duplex incorporating T-A, A-ψ, G-PIC, and C-G, and triplex forming oligonucleotide incorporating T, CBr, YO, and Py formed the triplex as evaluated by Tm measurements. The triplex formation was successfully applied to the inhibition of transcription of the DNA duplex incorporating T7-promoter sequence modified by the above modified bases.

Abstract
Selective modification of nucleobases with photolabile caging groups enables the study and control of processes and interactions of nucleic acids. Numerous positions on nucleobases have been targeted, but all involve formal substitution of a hydrogen atom with a photocaging group. Nature, however, also uses ring-nitrogen methylation, such as m7 G and m1 A, to change the electronic structure and properties of RNA and control biomolecular interactions essential for translation and turnover. We report that aryl ketones such as benzophenone and α-hydroxyalkyl ketone are photolabile caging groups if installed at the N7 position of guanosine or the N1 position of adenosine. Common photocaging groups derived from the ortho-nitrobenzyl moiety were not suitable. Both chemical and enzymatic methods for site-specific modification of N7G in nucleosides, dinucleotides, and RNA were developed, thereby opening the door to studying the molecular interactions of m7 G and m1 A with spatiotemporal control.

Abstract
Immunomodulatory therapies are becoming a paradigm-shifting treatment modality for cancer. Despite promising clinical results, cancer immunotherapy is accompanied with off-tumor toxicity and autoimmune adverse effects. Thus, the development of smarter systems to regulate immune responses with superior spatiotemporal precision and enhanced safety is urgently needed. Here we report an activatable engineered immunodevice that enables remote control over the antitumor immunity in vitro and in vivo with near-infrared (NIR) light. The immunodevice is composed of a rationally designed UV light-activatable immunostimulatory agent and upconversion nanoparticle, which acts as a transducer to shift the light sensitivity of the device to the NIR window. The controlled immune regulation allows the generation of effective immune response within tumor without disturbing immunity elsewhere in the body, thereby maintaining the antitumor efficacy while mitigating systemic toxicity. The present work illustrates the potential of the remote-controlled immunodevice for triggering of immunoactivity at the right time and site.

Abstract
We report proof of principle biomimetic switching of transcription in vitro through non-natural chemical reactions in the major groove of DNA templates. Photocaged DNA templates containing nitrobenzyl-protected 5-hydroxymethyluracil or - cytosine permitted no transcription with E. coli RNA polymerase (OFF state). Their irradiation with 400 nm light resulted in DNA templates containing hydroxymethylpyrimidines, which switched transcription ON with a higher yield (250-350%) compared to non-modified DNA. Phosphorylation of templates containing 5-hydroxymethyluracil (but not 5-hydroxymethylcytosine) then turned transcription OFF again. It is the first step towards artificial bioorthogonal chemical epigenetics.

Abstract
Nucleosides, nucleotides and 2'-deoxyribonucleoside triphosphates (dNTPs) containing 5-(hydroxymethyl)uracil protected with photocleavable groups (2-nitrobenzyl-, 6-nitropiperonyl or 9-anthrylmethyl) were prepared and tested as building blocks for the polymerase synthesis of photocaged oligonucleotides and DNA. Photodeprotection (photorelease) reactions were studied in detail on model nucleoside monophosphates and their photoreaction quantum yields were determined. Photocaged dNTPs were then tested and used as substrates for DNA polymerases in primer extension or PCR. DNA probes containing photocaged or free 5-hydroxymethylU in the recognition sequence of restriction endonucleases were prepared and used for the study of photorelease of caged DNA by UV or visible light at different wavelengths. The nitropiperonyl-protected nucleotide was found to be a superior building block because the corresponding dNTP is a good substrate for DNA polymerases, and the protecting group is efficiently cleavable by irradiation by UV or visible light (up to 425 nm).

Abstract
On-cue regulation of gene transcription is an invaluable tool for the study of biological processes and the development and integration of next-generation therapeutics. Ideal reagents for the precise regulation of gene transcription should be nontoxic to the host system, highly tunable, and provide a high level of spatial and temporal control. Light, when coupled with protein or small molecule-linked photoresponsive elements, presents an attractive means of meeting the demands of an ideal system for regulating gene transcription. In this review, we cover recent developments in the burgeoning field of light-regulated gene transcription, covering both genetically encoded and small-molecule based strategies for optical regulation of transcription during the period 2012 till present.

Abstract
Methyltransferases are powerful tools for site-specific transfer of non-natural functional groups from synthetic analogs of their cosubstrate S-adenosyl-l-methionine (AdoMet). We present a new class of AdoMet analogs containing photo-caging (PC) groups in their side chain, enzymatic transfer of PC groups by a promiscuous DNA MTase as well as light-triggered removal from the target DNA. This strategy provides a new avenue to reversibly modulate the functionality of DNA at MTase target sites.

Abstract
Biological processes are naturally regulated with high spatial and temporal control, as is perhaps most evident in metazoan embryogenesis. Chemical tools have been extensively utilized in cell and developmental biology to investigate cellular processes, and conditional control methods have expanded applications of these technologies toward resolving complex biological questions. Light represents an excellent external trigger since it can be controlled with very high spatial and temporal precision. To this end, several optically regulated tools have been developed and applied to living systems. In this review we discuss recent developments of optochemical tools, including small molecules, peptides, proteins, and nucleic acids that can be irreversibly or reversibly controlled through light irradiation, with a focus on applications in cells and animals.

Abstract
We describe a series of easily accessible, visible-light-sensitive (λ > 500 nm) BODIPY (boron-dipyrromethene)-based photoprotecting groups (PPGs) for primary and secondary amines, based on a carbamate linker. The caged compounds are stable under aqueous conditions for 24 h and can be efficiently uncaged in vitro with visible light (λ = 530 nm). These properties allow efficient photodeprotection of amines, rendering these novel PPGs potentially suitable for various applications, including the delivery of caged drugs and their remote activation.

Abstract
The photocontrol of protein expression enables the spatiotemporal induction of biological events in living cells or organisms. However, commonly used method such as photocontrollable transcription factor or caged nucleic acids is unsuitable for precise control of the duration of protein expression. Here, I report a photocontrollable cap (PC-cap) that can control the translation of mRNA in a reversible manner via its cis-trans photoisomerization through illumination with 370 and 430 nm light. 2-meta-Methyl-phenylazo cap (mMe-2PA-cap) in the trans form silences translation in zebrafish embryo, whereas treatment with the cis form provided a 7.1 times larger amount of translated protein compared to the trans form. Moreover, translation activated by illumination of the embryo with 370 nm light was rapidly inactivated again by subsequent illumination with 430 nm light. An application of this approach was demonstrated by photoinducing the development of double-headed zebrafish by controlling the expression period of squint protein.

Abstract
Bacterial and viral CpG oligonculeotides are unmethylated cytosine-phosphate-guanosine dinucleotide sequences and trigger an innate immune response through activation of the toll-like receptor 9 (TLR9). We have developed synthetic photocaged CpGs via site-specific incorporation of nitropiperonyloxymethyl (NPOM)-caged thymidine residues. These oligonucleotides enable the optical control of TLR9 function and thereby provide light-activation of an immune response. We provide a proof-of-concept model by applying a reporter assay in live cells and by quantification of endogenous production of interleukin 6.

Abstract
Introduction of 4,4'-bis(hydroxymethyl)-azobenzene (azo) to dumbbell hairpin oligonucleotides at the loop position was able to reversibly control the stability of the whole hairpin structure via UV or visible light irradiation. Here, we designed and synthesized a series of azobenzene linked dumbbell antisense oligodeoxynucleotides (asODNs) containing two terminal hairpins that are composed of an asODN and a short inhibitory sense strand. Thermal melting studies of these azobenzene linked dumbbell asODNs indicated that efficient trans to cis photoisomerization of azobenzene moieties induced large difference in thermal stability (ΔTm = 12.1-21.3 °C). In addition, photomodulation of their RNA binding abilities and RNA digestion by RNase H was investigated. The trans-azobenzene linked asODNs with the optimized base pairs between asODN strands and inhibitory sense strands could only bind few percentage of the target RNA, while it was able to recover their binding to the target RNA and degrade it by RNase H after light irradiation. Upon optimization, it is promising to use these azobenzene linked asODNs for reversible spatial and temporal regulation of antisense activities based on both steric binding and RNA digestion by RNase H.

Abstract
Light-activated ("caged") compounds have been widely employed for studying biological processes with high spatial and temporal control. In the past decade, several new approaches for caging the structure and function of DNA and RNA oligonucleotides have been developed. This review focuses on caged oligonucleotides that incorporate site-specifically one or two photocleavable linkers, whose photolysis yields oligonucleotides with dramatic structural and functional changes. This technique has been employed by our laboratory and others to photoregulate gene expression in cells and living organisms, typically using near UV-activated organic chromophores. To improve capabilities for in vivo studies, we harnessed the rich inorganic photochemistry of ruthenium bipyridyl complexes to synthesize Ru-caged morpholino antisense oligonucleotides that remain inactive in zebrafish embryos until uncaged with visible light. Expanding into new caged oligonucleotide applications, our lab has developed Transcriptome In Vivo Analysis (TIVA) technology, which provides the first noninvasive, unbiased method for isolating mRNA from single neurons in brain tissues. TIVA-isolated mRNA can be amplified and then analyzed using next-generation sequencing (RNA-seq).
