Abstract
The interstrand crosslinking and threaded structures of nucleic acids have high potential in oligonucleotide therapeutics, chemical biology, and nanotechnology. For example, properly designed crosslinking structures provide high activity and nuclease resistance for anti-miRNAs. The noncovalent labeling and modification by the threaded structures are useful as new chemical biology tools. Photoreversible crosslinking creates smart materials, such as reversible photoresponsive gels and DNA origami objects. This review introduces the creation of interstrand crosslinking and threaded structures, such as catenanes and rotaxanes, based on hybridization-specific chemical reactions and their functions and perspectives.

Abstract
In the process of cell development and differentiation, C-5-methylation of cytosine (5-methylcytosine: 5-mC) in genome DNA is an important transcriptional regulator that switches between differentiated and undifferentiated states. Further, abnormal DNA methylations are often present in tumor suppressor genes and are associated with many diseases. Therefore, 5-mC detection technology is an important tool in the most exciting fields of molecular biology and diagnosing diseases such as cancers. In this study, we found a novel photo-crosslinking property of psoralen-conjugated oligonucleotide (Ps-Oligo) to the double-stranded DNA (ds-DNA) containing 5-mC in the presence of a cationic comb-type copolymer, poly(allylamine)-graft-dextran (PAA-g-Dex). Photo-crosslinking efficiency of Ps-Oligo to 5-mC in ds-DNA was markedly enhanced in the presence of PAA-g-Dex, permitting 5-mC-targeted crosslinking. We believe that the combination of PAA-g-Dex and Ps-Oligo will be an effective tool for detecting 5-mC in genomic DNA.

Abstract
Crosslinking reactions to nucleic acids are an effective way to prepare stable complexes formed by covalent bonding. We demonstrated that fully 2'-O-methylated (2'-OMe) RNAs having a 2-amino-6-vinylpurine (AVP) exhibited an efficient crosslinking to uracil in the target RNA. Recently, we reported the preparation of crosslinked 2'-OMe RNA duplexes using AVP and the anti-miRNA oligonucleotides (AMOs) containing crosslinked duplexes at the terminal positions. These AMOs exhibited efficient microRNA (miRNA) inhibition at very low concentrations. In this article, we describe the chemical synthesis of 2'-OMe oligonucleotides containing AVP and preparation of the AMOs bearing crosslinked 2'-OMe RNA duplexes using AVP. In addition, we describe in detail the miRNA inhibition assay using these AMOs. © 2022 Wiley Periodicals LLC.

Abstract
Point mutations are well characterized activators of oncogenes but are often indistinguishable using common gene technologies. In general, the precise sites of point-mutated oncogenes are difficult to distinguish under physiological conditions primarily because single nucleotide mismatch do not affect the annealing temperatures of DNA probes sufficiently. To address this limitation, we developed photo-responsive oligodeoxyribonucleotides containing 2'-O-[N-(4,5',8-trimethylpsoralen-4'-ylmethylcarbamoyl)]adenosine (Ps-amd-Oligo), which can be used to selectively manipulate and identify genes with point mutations. Here we present time course analyses of the photo-cross-linking efficiency of Ps-amd-Oligo with DNA and RNA and show promising selectivity for the oncogene H-ras.

Abstract
This article describes procedures to synthesize 2'-OMe-RNA modified with cross-linkable 2-amino-7-deaza-7-propynyl-6-vinylpurine (ADpVP) and preparation of the RNA-crosslinking experiment in vitro. All synthesis steps yield the desired compound in moderate or high yield without expensive chemical reagents or specific devices. The crosslink-active form of modified RNA can also be purified by commonly used reversed-phase HPLC, can be stored at -80°C after lyophilization for a few days, and is ready to use for crosslinking experiments. This crosslink-active RNA can efficiently form covalent bonds with complementary RNA in a sequence-specific manner. © 2019 by John Wiley & Sons, Inc.
