    ABSTRACT: Over the past few years, molecular oncology research has revealed that abnormalities in both protein coding genes (PCGs) and noncoding RNAs (ncRNAs) can be identified in tumors and that the interplay between PCGs and ncRNAs is causally involved in the initiation, progression and metastases of human cancers. MicroRNAs (miRNAs), which are among the most studied ncRNAs, are small 19- to 25-nucleotide genes involved in the regulation of PCGs and other ncRNAs. With the recent findings of miRNAs' involvement in cancer, miRNAs are strongly associated with the pathogenesis in human cancers. In this review, we focus on the possible mechanisms of miRNAs in cancer pathogenesis.

    ABSTRACT: The novel multi-arm DNA structures were designed using 2D-DNA Origami method, and these structures were folded into 3D hollow prism structures by introduction of connection strands into the arms. The opening of the prism structures were examined by a high-speed AFM, which showed the dissociation events of the connecting arms in the 3D-structures.

    ABSTRACT: DNA damage was monitored by fluorescent microscopy observations of DNA fluorescent images after hydrodynamic stretching on a microscope glass. DNA double-strand breaks lead to a decrease of the average length of observed fluorescent DNA molecules. Compared to conventional methods such as electrophoresis, the proposed method allows for the analysis of the DNA damage at very low DNA breaking frequency. In particular, this method was used to study DNA damage by weak UV irradiation in solutions of quantum dots.

    ABSTRACT: We report herein the synthesis and structural aspects of 4′selenouridine (11) and 4′selenocytidine (13), novel nucleoside derivatives. 4′Selenouridine (11) was synthesized via the stereoselective selenoPummerer reaction between an appropriately protected selenoxide 9 and a persilylated uracil. 4′Selenocytidine (13) was prepared from 4′selenouridine derivative 10. To the best of our knowledge, this is the first example concerning introduction of a heterocycle into the α- position of a seleno atom.

    ABSTRACT: We present a combined experimental and theoretical approach, whereby a comparison of calculated and experimental 15N NMR chemical shifts allows the elucidation of hydrogen-bond structure in a ligand-nucleobase complex inside duplex DNA. In this work, we focus on the highly selective interaction of 2-amino-7-methyl-1,8-naphthyridine (AMND) to cytosine (C) base opposite the abasic site in DNA duplexes, despite the hydrogen-bond array of neutral AMND being fully complementary to guanine (G). Examination of the salt dependence of the binding constants reveals that the effective number of charges on the ligand is +1.0, indicating protonated AMND does bind to C. This is clearly supported by 15N NMR measurements, where the drastic changes in chemical shift are observed for the aromatic nitrogens on the ligand when binding to C. Furthermore, from the complexation-induced changes in chemical shift at 15N1 (83.1 ppm upfield), 15N8 (14.1 ppm upfield), and 15NH2 (18.3 ppm downfield) on AMND, the ligand is found to bind to C via three point hydrogen-bonds. The chemical shifts of the AMND-C complex, calculated by gauge-independent atomic orbital-DFT method, are in fair agreement with the experimental values. These results clearly explain the selective binding of AMND to C over G in abasic site-containing duplex DNA.

    ABSTRACT: A novel bridged nucleic acid, 3'-amino-2'-deoxy-3',4'-BNA, having an N3'-->P5' phosphoramidate linkage and an S-type conformation, was successfully synthesized. It showed selective hybridization ability toward ssDNA complements, and high enzymatic stability against snake venom phosphodiesterase.

    ABSTRACT: Experimental strategies involving in vitro selection, designed to test the validity of the "RNA World Hypothesis", have demonstrated a significantly broader catalytic range for RNA (and, nucleic acids in general) than found in naturally occurring ribozymes. We wished to explore whether photochemical reactions could be catalyzed by nucleic acid enzymes. In vitro selection experiments were carried out to obtain "photolyase" deoxyribozymes, capable of photoreversing thymine cyclobutane dimers in the presence of a cofactor, serotonin. During in vitro selection from a thymine-dimer containing random DNA library, irradiated with light >300 nm, two pools of catalytic nucleic molecules emerged--one that required serotonin for activity, and another pool that, surprisingly, did not. Characterization of the serotonin-independent clones indicated the optimal wavelength for its repair activity (approximately 1,400-fold) to be approximately 300 nm, notably red-shifted from the absorption maximum of the DNA itself. The folded enzyme may contain a G-quadruplex (whose spectra have red-shifted tails relative to duplex absorbance), and our hypothesis has the folded enzyme as an antenna for the efficient channelling of light or electrons to the thymine dimer, much in the manner of protein photolyases.

    ABSTRACT: An effective and simple technology is required to identify genes that function in a particular phenotype of interest. A system for identification of genes with libraries of randomized ribozymes has a great potential to investigate gene functions and cellular pathways. This system has been used to identify genes that are relevant to several phenotypes. In vivo application of the library of ribozymes in mice model was also performed to identify genes involved in metastasis. Libraries of ribozymes might be used in vitro and in vivo to study various aspects of basic cell biology and disease processes including metastasis.

    ABSTRACT: We determined solution structure of d(GGAGGTTTTGGAGG) (D14) in the presence of Na+ ions by NMR. Two molecules of D14 form a quadruplex strucure with parallel and antiparallel strand alignments. The quadruplex is formed by four helical GGAGG segments and two diagonal TTTT loops at the top and bottom of the helix. This quadruplex structure is entirely different from that of r(GGAGGUUUUGGAGG) (R14), which has been previously determined by NMR. In the case of RNA, R14 forms an intra-strand parallel quadruplex with a UUUU loop a t lateral position ofthe helix and two such molecules form a dimer by stacking. The factors determining the type of RNA and DNA quadruplexes are discussed.

    ABSTRACT: New fluorescent nucleosides, methoxybenzodeazaadenine ((MD)A) and methoxybenzodeazainosine ((MD)I) which can sharply distinguish between C and T bases, respectably. The hybridization of an ODN probe containing (MD)A and (MD)I with a target DNA facilitates the judgment with the fluorescence spectra of the type of pyrimidine bases located at a specific site on the target DNA. The (MD)A- and (MD)I containing ODN are very effective probes for pyrimidine SNP typing.

    ABSTRACT: The reaction mechanism of C-6 lithiation of uridine mediated by lithium hexamethyldisilazide (LiHMDS) has been investigated. LiHMDS alone dose not lithiate at C-6 of uridine. However, in the presence of an appropriate silylating agent, e.g. trimethylsilyl chloride, the reaction of 1 with LiHMDS allowed to lithiate at C-6 and gave the corresponding C-6 silylated product 2. The experimental results shown below revealed that O-4 (N-3) of uracil moiety may be temporarily masked by silylation, which triggers the C-6 lithiation by lowering the pKa of H-6. The reaction could efficiently be applied to the synthesis of 6,5'-C-cyclouridine, a nucleoside analogue fixed in a specific glycosyl torsion angle by a carbon-carbon bridge.
