Determination of Methylation Site of DNA-Methyltransferase NlaX by a Hybrid Method
Using a new method based on a combination of bisulfite reaction, the repair enzyme uracil-DNA glycosylase, and synthetic oligodeoxyribonucleotides, the methylation site of DNA-methyltransferase NlaX (M·NlaX) from Neisseria lactamica was established to be

Synthesis and anti-HIV activity of thiocholesteryl-coupled phosphodiester antisense oligonucleotides incorporated into immunoliposomes [PDF]
Encapsulation of oligonucleotides in antibody-targeted liposomes (immunoliposomes) which bind to target cells permits intracellular delivery of the oligonucleotides.

Microwave-assisted rapid deprotection of oligodeoxyribonucleotides [PDF]
A novel method for the deprotection of oligodeoxyribonucleotides under microwave irradiation has been developed. The oligodeoxynucleotides having base labile, phenoxyacetyl (pac), protection for exocyclic amino functions were fully deprotected in 0. 2 M sodium hydroxide (methanol:water : : 1:1, v/v) = A and 1 M sodium hydroxide (methanol:water : : 1:1,

The preparation of a disulfide-tethered precipitative soluble support and its use for solution-phase synthesis of trimeric oligodeoxyribonucleotide 3´-(2-chlorophenylphosphate) building blocks is described. To obtain the building blocks, N-acyl protected

The rationale for the synthesis of cationic modified nucleosides is higher expected nuclease resistance and potentially better cellular uptake due to an overall reduced negative charge based on internal charge compensation.

Transport Oligonucleotides—A Novel System for Intracellular Delivery of Antisense Therapeutics
Biological activity of antisense oligonucleotides (asON), especially those with a neutral backbone, is often attenuated by poor cellular accumulation. In the present proof-of-concept study, we propose a novel delivery system for asONs which implies the ...

Imidazopurinones are markers of physiological genomic damage linked to DNA instability and glyoxalase 1-associated tumour multidrug resistance [PDF]
Glyoxal and methylglyoxal are reactive dicarbonyl metabolites formed and metabolized in physiological systems. Increased exposure to these dicarbonyls is linked to mutagenesis and cytotoxicity and enhanced dicarbonyl metabolism by overexpression of ...

A novel approach to the synthesis of oligodeoxyribonucleotide boranophosphates [PDF]
Deoxyribonucleoside 3'-boranophosphate derivatives including adenine, cytosine, guanine, and thymine bases were synthesized in good yields by the use of a new boranophosphorylation reaction. The reaction was found to be effective for the formation of internucleotidic boranophosphate linkages.

Through transfection of short single-stranded oligodeoxyribonucleotides (ssODNs) small genomic alterations can be introduced into mammalian cells with high precision. ssODNs integrate into the genome during DNA replication, but the resulting heteroduplex

Biophysical and biological properties of quadruplex oligodeoxyribonucleotides [PDF]
Single-stranded guanosine-rich oligodeoxyribonucleotides (GROs) have a propensity to form quadruplex structures that are stabilized by G-quartets. In addition to intense speculation about the role of G-quartet formation in vivo, there is considerable interest in the therapeutic potential of quadruplex oligonucleotides as aptamers or non-antisense ...
