    • The present invention provides nucleic acid molecules, DNA constructs, plasmids, and methods for post-transcriptional regulation of gene expression using RNA molecules to both repress and activate translation of an open reading frame. Repression of gene expression is achieved through the presence of a regulatory nucleic acid element (the cis-repressive RNA or crRNA) within the 5' untranslated region (5' UTR) of an mRNA molecule. The nucleic acid element forms a hairpin (stem/loop) structure through complementary base pairing. The hairpin blocks access to the mRNA transcript by the ribosome, thereby preventing translation. In particular, in embodiments of the invention designed to operate in prokaryotic cells, the stem of the hairpin secondary structure sequesters the ribosome binding site (RBS). In embodiments of the invention designed to operate in eukaryotic cells, the stem of the hairpin is positioned upstream of the start codon, anywhere within the 5' UTR of an mRNA. A small RNA (trans-activating RNA, or taRNA), expressed in trans, interacts with the crRNA and alters the hairpin structure. This alteration allows the ribosome to gain access to the region of the transcript upstream of the start codon, thereby activating transcription from its previously repressed state.
    • 本发明提供核酸分子,DNA构建体,质粒和用于转录后调节基因表达的方法,其使用RNA分子抑制和激活开放阅读框的翻译。 通过在mRNA分子的5'非翻译区(5'UTR)内存在调节性核酸元件(顺式抑制性RNA或crRNA)来实现基因表达的抑制。 核酸元件通过互补碱基配对形成发夹(茎/环)结构。 发夹阻止核糖体进入mRNA转录物,从而阻止翻译。 特别地,在设计用于在原核细胞中操作的本发明的实施方案中,发夹二级结构的茎螯合核糖体结合位点(RBS)。 在设计用于在真核细胞中操作的本发明的实施方案中,发夹的茎位于起始密码子的上游,位于mRNA的5'UTR内的任何位置。 以反式表达的小RNA(反式激活RNA或taRNA)与crRNA相互作用并改变发夹结构。 这种改变允许核糖体进入起始密码子上游的转录物区域,从而从其先前的抑制状态激活转录。

    • The invention provides a method for detecting and quantifying the amount of target molecules, such as nucleic acids or proteins in a sample. The target molecules are first recognized and bounded by target-specific probes, generally nucleic acids or proteins that bind specifically to the targets, each of which is labeled with a short single-stranded nucleic acid probe, either DNA or RNA, with distinct molecular weight. This label is called an oligonucleotide mass tag. One or several standard oligonucleotide sequences can be designed with similar sequence but distinct molecular weight to those oligonucleotide mass tags. Then the oligonucleotide mass tags associated with bounded probes and the standard sequences are co-amplified using a pair of common primers. The presence and/or amount of each oligonucleotide mass tag, which corresponds to the amount of corresponding target molecule, is determined by a primer extension reaction and quantification of the primer extension product.
    • 本发明提供了用于检测和定量样品中靶分子如核酸或蛋白质的量的方法。 目标分子首先被目标特异性探针识别并限制,通常是与靶标特异性结合的核酸或蛋白质,其中每个标记有短单链核酸探针,DNA或RNA,具有不同的分子量 。 该标签称为寡核苷酸质量标签。 可以设计一个或几个标准寡核苷酸序列,其具有与那些寡核苷酸质量标签相似的序列但分子量不同。 然后使用一对普通引物共同扩增与有界探针和标准序列相关的寡核苷酸质粒标签。 通过引物延伸反应和引物延伸产物的定量来确定对应于相应靶分子量的每个寡核苷酸质粒标签的存在和/或量。

    • The present invention provides an efficient way for high throughput haplotype analysis. Several polymorphic nucleic acid markers, such as SNPs, can be simultaneously and reliably determined through multiplex PCR of single nucleic acid molecules in several parallel single molecule dilutions and the consequent statistical analysis of the results from these parallel single molecule multiplex PCR reactions results in reliable determination of haplotypes present in the subject. The nucleic acid markers can be of any distance to each other on the chromosome. In addition, an approach wherein overlapping DNA markers are analyzed can be used to link smaller haplotypes into larger haplotypes. Consequently, the invention provides a powerful new tool for diagnostic haplotyping and identifying novel haplotypes.
