Abstract
Here, we describe the design and synthesis of a new reduction-cleavable spacer (RCS) based on a nitrobenzene scaffold for constructing reduction-responsive oligonucleotides according to standard phosphoramidite chemistry. In addition, we demonstrate that the introduction of the RCS in the middle of an oligonucleotide (30 nt) enables the construction of a self-assembled microsphere capable of exhibiting a reduction-responsive disassembly.

Abstract
RNA is a central molecule in numerous cellular processes, including transcription, translation, and regulation of gene expression. To reveal the numerous facets of RNA function and metabolism in cells, labeling has become indispensable and enables the visualization, isolation, characterization, and even quantification of certain RNA species. In this review, we will cover chemoenzymatic approaches for covalent RNA labeling. These approaches rely on an enzymatic step to introduce an RNA modification before conjugation with a label for detection or isolation. We start with in vitro manipulation of RNA, sorted according to the enzymatic reaction exploited. Then, metabolic approaches for co- and post-transcriptional RNA labeling will be treated. We focus on recent advances in the field and highlight the most relevant applications for cellular imaging, RNA isolation and sequencing.

Abstract
AbstractHerein, we describe the construction of a reduction-responsive oligonucleotide by post-modification of an oligonucleotide with a diazo compound bearing a 4-nitrobenzyl group as a reduction-responsive cleavable moiety. High-performance liquid chromatography and mass spectrometry were used to reveal the introduction of a 4-nitrobenzyl group to the 5′-phosphate group of an oligonucleotide, and the subsequent reduction-triggered recovery of the original oligonucleotide. The protocol used for the preparation of this reduction-responsive oligonucleotide is simple and it will have various applications in the fields of chemical and synthetic biology.

Abstract
5-Hydroxymethylcytosine and uracil are epigenetic nucleobases, but their biological roles are still unclear. 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
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
Stimuli-controlled structural transitions of nucleic acids have received growing attentions owing to their potential applications in the fields of chemical and synthetic biology. Here, we describe the development of reduction-responsive deoxyribonucleic acid (DNA) duplexes, in which guanine rings bearing a reduction-responsive cleavable nitrobenzyl (NB) group at the O 6 position (GNB) are introduced at defined positions. We demonstrate that the artificial NB group can be removed in response to reduction stimulus without the dissociation of the intermolecular duplex structure, which comprises a G-quadruplex forming nucleic acid strand with one GNB and its complementary sequence with one mismatch pair. Meanwhile, another duplex that comprised a G-quadruplex forming nucleic acid strand with two GNB and its complementary sequence with three mismatch pairs exhibited reduction-responsive structural transitions from intermolecular duplex to intramolecular quadruplex. These findings might be useful for the development of DNA architectures endowed with reduction-responsive functions.

Abstract
Oligonucleotides (ONs) have been envisaged for therapeutic applications for more than thirty years. However, their broad use requires overcoming several hurdles such as instability in biological fluids, low cell penetration, limited tissue distribution, and off-target effects. With this aim, many chemical modifications have been introduced into ONs definitively as a means of modifying and better improving their properties as gene silencing agents and some of them have been successful. Moreover, in the search for an alternative way to make efficient ON-based drugs, the general concept of prodrugs was applied to the oligonucleotide field. A prodrug is defined as a compound that undergoes transformations in vivo to yield the parent active drug under different stimuli. The interest in stimuli-responsive ONs for gene silencing functions has been notable in recent years. The ON prodrug strategies usually help to overcome limitations of natural ONs due to their low metabolic stability and poor delivery. Nevertheless, compared to permanent ON modifications, transient modifications in prodrugs offer the opportunity to regulate ON activity as a function of stimuli acting as switches. Generally, the ON prodrug is not active until it is triggered to release an unmodified ON. However, as it will be described in some examples, the opposite effect can be sought. This review examines ON modifications in response to various stimuli. These stimuli may be internal or external to the cell, chemical (glutathione), biochemical (enzymes), or physical (heat, light). For each stimulus, the discussion has been separated into sections corresponding to the site of the modification in the nucleotide: the internucleosidic phosphate, the nucleobase, the sugar or the extremities of ONs. Moreover, the review provides a current and detailed account of stimuli-responsive ONs with the main goal of gene silencing. However, for some stimuli-responsive ONs reported in this review, no application for controlling gene expression has been shown, but a certain potential in this field could be demonstrated. Additionally, other applications in different domains have been mentioned to extend the interest in such molecules.

Abstract
Hydrogen peroxide (H2O2) is a reactive oxygen species (ROS) involved in various diseases, including neurodegeneration, diabetes, and cancer. Here, we introduce a new approach to use H2O2 to modulate specific gene expression in mammalian cells. H2O2-responsive nucleoside analogues, in which the Watson-Crick faces of the nucleobases are caged by arylboronate moieties, were synthesized. One of these analogues, boronated thymidine (dTB ), was incorporated into oligodeoxynucleotides (ODNs) using an automated DNA synthesizer. The hybridization ability of this boronated ODN to complementary RNA was clearly switched in the off-to-on direction upon H2O2 addition. Furthermore, we demonstrated H2O2-triggered gene silencing in mammalian cells using antisense oligonucleotides (ASOs) modified with dTB . Our approach can be used for the regulation of any gene of interest by the sequence design of boronated ASOs and will contribute to the development of targeted disease therapeutics.
