Abstract: The present invention provides novel compositions, kits and methods employing RNA 5? polyphosphatases, RNA 5? monophosphatases, capping enzymes, decapping enzymes, nucleic acid pyrophosphatases and RNA ligases, as well as other enzymes, for selective 5? ligation tagging of desired classes of RNA molecules that differ with respect to particular chemical moieties on their 5? ends. The 5? tagged RNA molecules can be used for synthesis of tagged first-stand cDNA, double-stranded cDNA, and sense or antisense RNA for a variety of uses.

Abstract: The present invention provides a method for identification of differentially methylated genomic CpG dinucleotide sequences within genomic target sequences that are associated with cancer in an individual by obtaining a biological sample comprising genomic DNA from the individual measuring the level or pattern of methylated genomic CpG dinucleotide sequences for two or more of the genomic targets in the sample, and comparing the level of methylated genomic CpG dinucleotide sequences in the sample to a reference level of methylated genomic CpG dinucleotide sequences, wherein a difference in the level or pattern of methylation of the genomic CpG dinucleotide sequences in the sample compared to the reference level identifies differentially methylated genomic CpG dinucleotide sequences associated with cancer. As disclosed herein, the methods of the invention have numerous diagnostic and prognostic applications.
