Based on the above and on the remarkable properties of the 2′-O,4′-C-methylene bridged LNA monomers it was decided to synthesise oligonucleotides comprising one or more 2′-O,4′-C-methylene-β-D-xylofuranosyl nucleotide monomer(s) as the first stereoisomer of LNA modified oligonucleotides. Modelling clearly indicated the xylo-LNA monomers to be locked in an N-type furanose conformation. Whereas the parent 2′-deoxy-β-D-xylofuranosyl nucleosides were shown to adopt mainly an N-type furanose conformation, the furanose ring of the 2′-deoxy-β-D-xylofuranosyl monomers present in xylo-DNA were shown by conformational analysis and computer modelling to prefer an S-type conformation thereby minimising steric repulsion between the nucleobase and the 3′-O-phopshate group (Seela, F.; Wömer, Rosemeyer, H. Helv. Chem. Acta 1994, 77, 883). As no report on the hybridisation properties and binding mode of xylo-configurated oligonucleotides in an RNA context was believed to exist, it was the aim to synthesise 2′-O,4′-C-methylene-β-D-xylofuranosyl nucleotide monomer and to study the thermal stability of oligonucleotides comprising this monomer. The results showed that fully modified or almost fully modified Xylo-LNA is useful for high-affinity targeting of complementary nucleic acids. When taking into consideration the inverted stereochemistry at C-3′ this is a surprising fact. It is likely that Xylo-LNA monomers, in a sequence context of Xylo-DNA monomers, should have an affinity-increasing effect.

Method for characterizing, classifying and differentiating tissues and cell types, for predicting the behavior of tissues and groups of cells, and for identifying genes with changed expression. The method involves obtaining genomic DNA from a tissue sample, the genomic DNA subsequently being subjected to shearing, cleaved by means of a restriction endonuclease or not treated by either one of these methods. The base cytosine, but not 5-methylcytosine, from the thus-obtained genomic DNA is then converted into uracil by treatment with a bisulfite solution. Fractions of the thus-treated genomic DNA are then amplified using either very short or degenerated oligonucleotides or oligonuclcotides which are complementary to adaptor oligonucleotides that have been ligated to the ends of the cleaved DNA. The quantity of the remaining cytosines on the guanine-rich DNA strand and / or the quantity of guanines on the cytosine-rich DNA strand from the amplified fractions are then detected by hybridization or polymerase reaction, which quantities are such that the data generated thereby and automatically applied to a processing algorithm allow the drawing of conclusions concerning the phenotype of the sample material.
