Abstract
Chemical modification of messenger RNA (mRNA) has paved the way for advancing mRNA-based therapeutics. The intricate process of mRNA translation in eukaryotes is orchestrated by numerous proteins involved in complex interaction networks. Many of them bind specifically to a unique structure at the mRNA 5'-end, called 5'-cap. Depending on the 5'-terminal sequence and its methylation pattern, different proteins may be involved in the translation initiation and regulation, but a deeper understanding of these mechanisms requires specialized molecular tools to identify natural binders of mRNA 5'-end variants. Here, a series of 8 new synthetic 5'-cap analogs that allow the preparation of RNA molecules with photoreactive tags using a standard in vitro transcription reaction are reported. Two photoreactive tags and four different modification sites are selected to minimize potential interference with cap-protein contacts and to provide complementary properties regarding crosslinking chemistry and molecular interactions. The tailored modification strategy allows for the generation of specific crosslinks with model cap-binding proteins, such as eIF4E and Dcp2. The usefulness of the photoreactive cap analogs is also demonstrated for identifying the cap-binding subunit in a multi-protein complex, which makes them perfect candidates for further development of photoaffinity labeling probes to study more complex mRNA-related processes.

Abstract
Photochromism is a reversible phenomenon wherein a material undergoes a change in color upon exposure to light. In organic photochromes, this effect often results from light-induced isomerization reactions, leading to alterations in either the spatial orientation or electronic properties of the photochrome. The incorporation of photochromic moieties into biomolecules, such as proteins or nucleic acids, has become a prevalent approach to render these biomolecules responsive to light stimuli. Utilizing light as a trigger for the manipulation of biomolecular structure and function offers numerous advantages compared to other stimuli, such as chemical or electrical treatments, due to its non-invasive nature. Consequently, light proves particularly advantageous in cellular and tissue applications. In this review, we emphasize recent advancements in the field of photochromic nucleosides and oligonucleotides. We provide an overview of the design principles of different classes of photochromes, synthetic strategies, critical analytical challenges, as well as structure-property relationships. The applications of photochromic nucleic acid derivatives encompass diverse domains, ranging from the precise photoregulation of gene expression to the controlled modulation of the three-dimensional structures of oligonucleotides and the development of DNA-based fluorescence modulators. Moreover, we present a future perspective on potential modifications and applications.

Abstract
Starting with the clinical application of two vaccines in 2020, mRNA therapeutics are currently being investigated for a variety of applications. Removing immunogenic uncapped mRNA from transcribed mRNA is critical in mRNA research and clinical applications. Commonly used capping methods provide maximum capping efficiency of around 80-90% for widely used Cap-0- and Cap-1-type mRNAs. However, uncapped and capped mRNA possesses almost identical physicochemical properties, posing challenges to their physical separation. In this work, we develop hydrophobic photocaged tag-modified cap analogs, which separate capped mRNA from uncapped mRNA by reversed-phase high-performance liquid chromatography. Subsequent photo-irradiation recovers footprint-free native capped mRNA. This approach provides 100% capping efficiency even in Cap-2-type mRNA with versatility applicable to 650 nt and 4,247 nt mRNA. We find that the Cap-2-type mRNA shows up to 3- to 4-fold higher translation activity in cultured cells and animals than the Cap-1-type mRNA prepared by the standard capping method.

Abstract
The 5' cap is a hallmark of eukaryotic mRNA involved in the initiation of translation. Its modification with a single photo-cleavable group can bring translation of mRNA under the control of light. However, UV irradiation causes cell stress and downregulation of translation. Furthermore, complex processes often involve timed expression of more than one gene. The approach would thus greatly benefit from the ability to photo-cleave by blue light and to control more than one mRNA at a time. We report the synthesis of a 5' cap modified with a 7-(diethylamino)coumarin (CouCap) and adapted conditions for in vitro transcription. Translation of the resulting CouCap-mRNA is muted in vitro and in mammalian cells, and can be initiated by irradiation with 450 nm. The native cap is restored and no non-natural residues nor sequence alterations remain in the mRNA. Multiplexing for two different mRNAs was achieved by combining cap analogs with coumarin- and ortho-nitrobenzyl-based photo-cleavable groups.

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
Photoswitchable oligonucleotides can determine specific biological outcomes by light-induced conformational changes. In particular, artificial probes activated by visible-light irradiation are highly desired in biological applications. Here, we report two novel types of visible-light photoswitchable peptide nucleic acids (PNAs) based on the molecular transducers: hemithioindigo and tetra-ortho-fluoroazobenzene. Our study reveals that the tetra-ortho-fluoroazobenzene-PNA conjugates have promising properties (fast reversible isomerization, exceptional thermal stability, high isomer conversions and sensitivity to visible-light irradiation) as reversible modulators to control oligonucleotide hybridization in biological contexts. Furthermore, we verified that this switchable modification delivers a slightly different hybridization behavior in the PNA. Thus, both melting experiments and strand-displacement assays showed that in all the cases the trans-isomer is the one with superior binding affinities. Alternative versions, inspired by our first compounds here reported, may find applications in different fields such as chemical biology, nanotechnology and materials science.

Abstract
Protein synthesis is critical to cell survival and translation regulation is essential to post-transcriptional gene expression regulation. Disorders of this process, particularly through RNA-binding proteins, is associated with the development and progression of a number of diseases, including cancers. However, the molecular mechanisms underlying the initiation of protein synthesis are intricate, making it difficult to find a drug that interferes with this process. Chemical probes are useful in elucidating the structures of RNA-protein complex and molecular mechanism of biological events. Moreover, some of these chemical probes show certain therapeutic benefits and can be further developed as leading compounds. Here, we will briefly review the general process and mechanism of protein synthesis, and emphasis on chemical probes in examples of probing the RNA structural changes and RNA-protein interactions. Moreover, the therapeutic potential of these probes is also discussed to give a comprehensive understanding.

Abstract
In contrast to small molecules, DNA and RNA macromolecules can be accurately formulated with base "elements" abbreviated as A, T, U, C, and G. However, the development of functionally artificial bases can result in the generation of new biomaterials with unique properties and applications. Therefore, we herein report the design and synthesis of a photoresponsive base as a new functional or molecular "element" for constructing DNA nanomolecules. The new base is made by fusion of an azobenzene with a natural T base (zT). zT, a new molecular element, is not only the most size-expanded T analogue but also a photoresponsive base capable of specific self-assembly through hydrogen bonding. Our results showed that stable and selective self-assembly of double-stranded DNAs occurred through zT-A base pairing, but it could still be efficiently dissociated by light irradiation. The photoresponsive DNA bases will provide the versatility required for constructing desired DNA nanomolecules and nanodevices.

mRNA is a template for protein biosynthesis, and consequently mRNA transport, translation, and turnover are key elements in the overall regulation of gene expression. Along with growing interest in the mechanisms regulating mRNA decay and localization, there is an increasing need for tools enabling convenient fluorescent labeling or affinity tagging of mRNA. We report new mRNA 5' cap analog-based tools that enable site-specific labeling of RNA within the cap using N-hydroxysuccinimide (NHS) chemistry. We explored two complementary methods: a co-transcriptional labeling method, in which the label is first attached to a cap analog and then incorporated into RNA by in vitro transcription, and a post-transcriptional labeling method, in which an amino-functionalized cap analog is incorporated into RNA followed by chemical labeling of the resulting transcript. After testing the biochemical properties of RNAs carrying the novel modified cap structures, we demonstrated the utility of fluorescently labeled RNAs in decapping assays, RNA decay assays, and RNA visualization in cells. Finally, we also demonstrated that mRNAs labeled by the reported method are translationally active. We envisage that the novel analogs will provide an alternative to radiolabeling of mRNA caps for in vitro studies and open possibilities for new applications related to the study of mRNA fates in vivo.

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
The cap is a natural modification present at the 5' ends of eukaryotic messenger RNA (mRNA), which because of its unique structural features, mediates essential biological functions during the process of gene expression. The core structural feature of the mRNA cap is an N7-methylguanosine moiety linked by a 5'-5' triphosphate chain to the first transcribed nucleotide. Interestingly, other RNA 5' end modifications structurally and functionally resembling the m7G cap have been discovered in different RNA types and in different organisms. All these structures contain the 'inverted' 5'-5' oligophosphate bridge, which is necessary for interaction with specific proteins and also serves as a cleavage site for phosphohydrolases regulating RNA turnover. Therefore, cap analogs containing oligophosphate chain modifications or carrying spectroscopic labels attached to phosphate moieties serve as attractive molecular tools for studies on RNA metabolism and modification of natural RNA properties. Here, we review chemical, enzymatic, and chemoenzymatic approaches that enable preparation of modified cap structures and RNAs carrying such structures, with emphasis on phosphate-modified mRNA cap analogs and their potential applications.

Abstract
The possibility of spatiotemporally photocontrolling translation holds considerable promise for studies on the biological roles of local translation in cells and tissues. Here we report caged aminoacyl-tRNAs (aa-tRNAs) synthesized using a (7-diethylaminocoumarin-4-yl)methoxycarbonyl (DEACM)-cage compound. DEACM-caged aa-tRNA does not spontaneously deacylate for at least 4 h in neutral aqueous solution, and does not bind to the elongation factor Tu. On irradiation at ∼405 nm at 125 mW cm−2, DEACM-aa-tRNA is converted into active aa-tRNA with a half-life of 19 s. Notably, this rapid uncaging induced by visible light does not impair the translation system. Translation is photoinduced when DEACM-aa-tRNA carrying a CCCG or a CUA anticodon is uncaged in the presence of mRNAs harbouring a CGGG four-base codon or a UAG amber codon, respectively. Protein synthesis is phototriggered in several model systems, including an in vitro translation system, an agarose gel, in liposomes and in mammalian cells. Spatiotemporal regulation of protein synthesis would advance studies into the consequences of localised protein translation in cells and tissues. Here, Ohtsuki et al. improve on an earlier caged-tRNA design to provide caged aminoacyl-tRNAs that are rapidly uncaged by visible light.

Abstract
In the present study, we demonstrate photoregulation of gene expression in a cell-free translation system from a T7 promoter containing two azobenzene derivatives at specific positions. As photoswitches, we prepared azobenzene-4'-carboxlyic acid (Azo) and 2,6-dimethylazobenzene-4'-carboxylic acid (DM-Azo), which were isomerized from trans to cis upon irradiation with UV light (λ < 370 nm), and 4-methylthioazobenzene-4'-carboxylic acid (S-Azo) and 2,6-dimethyl-4-(methylthio)azobenzene-4'-carobxylic acid (S-DM-Azo), which were cis-isomerized by irradiation with 400 nm visible light. Expression of green fluorescent protein from a promoter modified with S-Azo or S-DM-Azo could be induced by harmless visible light whereas that from a promoter modified with Azo or DM-Azo was induced only by UV light (340-360 nm). Thus, efficient photoregulation of green fluorescent protein production was achieved in a cell-free translation system with visible light without photodamage.

Abstract
Spatial and temporal control over chemical and biological processes plays a key role in life, where the whole is often much more than the sum of its parts. Quite trivially, the molecules of a cell do not form a living system if they are only arranged in a random fashion. If we want to understand these relationships and especially the problems arising from malfunction, tools are necessary that allow us to design sophisticated experiments that address these questions. Highly valuable in this respect are external triggers that enable us to precisely determine where, when, and to what extent a process is started or stopped. Light is an ideal external trigger: It is highly selective and if applied correctly also harmless. It can be generated and manipulated with well-established techniques, and many ways exist to apply light to living systems--from cells to higher organisms. This Review will focus on developments over the last six years and includes discussions on the underlying technologies as well as their applications.
