1. Notomi R., Sasaki S. and Taniguchi Y.*,, Recognition of 5-Methyl-CG and CG Base Pairs in Duplex DNA with High Stability using Antiparallel-type Triplex-formingOligonucleotides with 2-Guanidinoethyl-2'-deoxy-nebularine, Nucleic Acids Res, 10.1093/nar/gkac1110, 50, 12071-12081 (2022), 2022.11, The formation of triplex DNA is a site-specific recognition method that directly targets duplex DNA. However, triplex DNA formation is generally formed for the GC and AT base pairs of duplex DNA, and there are no natural nucleotides that recognize the CG and TA base pairs, or even 5mCG base pair. Moreover, duplex DNA, including 5mCG base pairs, epigenetically regulates gene expression in vivo, and, thus, targeting strategies are of biological importance. Therefore, the development of triplex-forming oligonucleotides (TFOs) with artificial nucleosides that selectively recognize these base pairs with high affinity is needed. We recently reported that 2’-deoxy-2-aminonebularine derivatives exhibited the ability to recognize 5mCG and CG base pairs in triplex formation; however, this ability was dependent on sequences. Therefore, we designed and synthesized new nucleoside derivatives based on the 2’-deoxy-nebularine (dN) skeleton to shorten the linker length connecting to the hydrogen-bonding unit in the anti-parallel motif triplex formation. We successfully demonstrated that TFOs with 2-guanidinoethyl-2'-deoxynebularine (guanidino-dN) recognized 5mCG and CG base pairs with very high affinity in all four DNA sequences with different adjacent nucleobases of guanidino-dN as well as in the promoter sequences of human genes containing 5mCG base pairs with a high DNA methylation frequency..
2. Miyahara R. and Taniguchi Y.*, Selective Unnatural Base Pairing and Recognition of 2-Hydroxy-2'-deoxyadenosine in DNA by Pseudo-dC Derivatives, J. Am. Chem. Soc., DOI: https://doi.org/10.1021/jacs.2c07000, 144 (35) 16150-16156 (2022), 2022.08, The formation of unnatural base pairs within duplex DNA would facilitate DNA nanotechnology and biotechnology.
Iso-2′-deoxyguanosine (iso-dG) forms base pairs with iso-2′-deoxycytidine, and its use as an unnatural base pair was investigated.
Iso-dG is one of the tautomers of 2-hydroxy-2′-deoxyadenosine (2-OH-dA), known as an oxidatively damaged nucleobase, and its
selective recognition in DNA plays an important role in the diagnosis and pathogenesis of disease. Therefore, we focused on pseudodC
(ψdC) as a suitable molecule that recognizes 2-OH-dA in DNA. Since 2-OH-dA shows tautomeric structures in DNA, we
designed and used ψdC, which also has a tautomeric structure. We successfully synthesized a ψdC phosphoramidite compound for
the synthesis of oligonucleotides (ODNs) as well as its triphosphate derivative (ψdCTP). Tm measurements revealed that ODNs
including ψdC showed stable base pair formation with ODNs having 2-OH-dA. In contrast, low Tm values were observed for other
bases (dG, dA, dC, and T). The results obtained for the single-nucleotide primer extension reaction revealed that ψdCTP was
incorporated into the complementary position of 2-OH-dA in template DNA with high selectivity. In addition, the primer elongation
reaction was confirmed to proceed in the presence of dNTPs. The present study reports an artificial nucleic acid that selectively and
stably forms unnatural base pairs with 2-OH-dA in DNA..
3. Wu J., Zhang M., Song L., Tan Y.,Taniguchi Y., Hipolito C. J., Zhang Y. and Yin Y.*, Implications of N7-hydrogen and C8-keto on the base pairing, mutagenic potential and repair of 8-oxo-2'-deoxy-adenosine:Investigation by nucleotide analogues, Bioorg. Chem., DOI:https://doi.org/10.1016/j.bioorg.2022.106029, 127, 106029 (2022), 2022.06, Oxidative lesions, such as 8-oxo-dG and 8-oxo-dA, are continuously generated from exposure to reactive oxygen
species. While 8-oxo-dG has been extensively studied, 8-oxo-dA has not received as much attention until recently.
Herein, we report the synthesis of duplex DNAs incorporating dA, 8-oxo-dA, 7-deaza-dA, 8-Br-dA, and 8-Br-7-
deaza-dA, which have different substitutions at 7- and 8-position, for the investigation into the implications of
N7-hydrogen and C8-keto on the base pairing preference, mutagenic potential and repair of 8-oxo-dA. Base
pairing study suggested that the polar N7-hydrogen and C8-keto of 8-oxo-dA, rather than the syn-preference,
might be essential for 8-oxo-dA to form a stable base pair with dG. Insertion and extension studies using KF-exo􀀀
and human DNA polymerase β indicated that the efficient dGTP insertion opposite 8-oxo-dA and extension past
8-oxo-dA:dG are contingent upon not only the stable base pair with dG, but also the flexibility of the active site in
polymerase. The N7-hydrogen in 8-oxo-dA or C7-hydrogen in 7-deaza-dA and 8-Br-7-deaza-dA was suggested to
be important for the recognition by hOGG1, although the excision efficiencies of 7-deaza-dA and 8-Br-7-deaza-dA
were much lower than 8-oxo-dA. This study provides an insight into the structure-function relationship of 8-oxodA
by nucleotide analogues..
