摘要:
A process is disclosed for generating at least one partially double-stranded target nucleic acid, which contains at least one single-stranded region at a terminal end. The process comprises the steps of (a) providing at least one primer, P1, containing at least one labile nucleotide; (b) combining at least one target nucleic acid sequence with P1 to generate a double-stranded polynucleotide containing at least one labile nucleotide; (c) exposing the double-stranded polynucleotide to conditions that promote single-strand cleavage of the polynucleotide at the site of the at least one labile nucleotide of primer P1; and (d) exposing the cleaved polynucleotide to conditions that promote the dissociation of the cleaved portions of primer P1 from a terminal end. The labile nucleotide may be dUTP, wherein the single-stranded cleavage of the polynucleotide at the site of the labile nucleotide occurs by treatment with uracil N-glycosylase.
摘要:
This application concerns improved methods of analyzing gene expression data where mRNA transcripts or representatives thereof that skew the gene expression profile of a cell or tissue sample are identified and removed from the population of mRNA transcripts prior to, during or subsequent to a reverse transcription reaction.
摘要:
Compositions and methods are provided for the treatment and diagnosis of diseases associated with the expression of one or more of the &bgr;I, &bgr;II, &ggr;, &dgr;, &egr;, &zgr; or &eegr; isoforms (isozymes) of protein kinase C (PKC). Oligonucleotides are provided which are targeted to nucleic acids encoding PKC-&bgr;I, PKC-&bgr;II, PKC-&ggr;, PKC-&dgr;, PKC-&egr;, PKC-&zgr; or PKC-&eegr;. Provided herein are oligonucleotides specifically hybridizable with a translation initiation site, 5′-untranslated region, 3′-untranslated region or other targeted region of a &bgr;I, &bgr;II, &ggr;, &dgr;, &egr;, &zgr; or &eegr; isoform of PKC, wherein at least about 75% of the nucleoside units of a given oligonucleotide are joined together by a stereospecific (i.e., Sp or Rp) phosphorothioate 3′ to 5′ linkages. In preferred embodiments, the oligonucleotides of the disclosure additionally contain one or more chemical modifications. Also disclosed are methods of using the oligonucleotides of the invention for modulating the expression of at least one of the &bgr;I, &bgr;II, &ggr;, &dgr;, &egr;, &zgr; or &eegr; isoforms of PKC and for treating animals suffering from disease amenable to therapeutic intervention by modulating the expression of one or more of the &bgr;I, &bgr;II, &ggr;, &dgr;, &egr;, &zgr; or &eegr; isoforms of PKC.
