    摘要: Disclosed are RNA polymerases consisting of a wild type RNA polymerase provided that at least one of amino acids in the wild type RNA polymerase has been modified to enhance its ability for incorporating 3′-deoxyribonucleotides and derivatives thereof in comparison with the corresponding wild type RNA polymerases. Specifically, disclosed are, for example, the RNA polymerases wherein at least one amino acid present in a nucleotide binding sites of the wild type RNA polymerases such as phenylalanine has been replaced with tyrosine. The RNA polymerases of the present invention are a RNA polymerase which exhibits little or no bias for incorporation between ribonucleotides and 3′-deoxyribonucleotide as well as among ribonucleotides having different base groups and among deoxyribonucleotides having. different base groups.

    摘要: Metastatic cancer cells originating from gastric cancer are detected by a method comprising the step of collecting a biological sample from a subject, the step of detecting the presence of at least either aldehyde dehydrogenase or dopa decarboxylase in the biological sample of the subject, and the step of determining that the possibility of containing metastatic cancer cells originating from the gastric cancer in the sample is high when at least either aldehyde dehydrogenase or dopa decarboxylase is present. By the use of these as markers for metastatic cancer cells originating from gastric cancer, the presence or absence of peritoneal metastasis in a gastric cancer patient can be detected rapidly and reliably, and data important for deciding whether intraperitoneal cancer chemotherapy should be applied is provided.

    摘要: The present invention provides methods for the sequencing of all RNA species within an RNA sample, such as the RNA content obtained from a cell, a tissue, a living organism, or from an artificial source. RNA molecules within the samples are labeled in a RNA-specific manner prior to immobilization on a solid support. One label is used to mark the location of the RNA molecule on the solid support, whereas the second label is used to mark selectively the S′ end of full-length mRNA molecules. RNA molecules are sequenced while being bound to the solid support in one or more sequencing reactions, and sequences of individual RNA molecules can be forwarded to computational analysis for assembling sequence information from individual sequencing reads obtained from the same location on the solid support. Not only unsupervised expression profiling on a genome-wide scale, but also the direct analysis of RNA-RNA interactions become possible as revealed by the analysis of the sequencing information obtained along with genomic information.
