    摘要: Massively parallel sequencing of cell-free, maternal plasma DNA was recently demonstrated to be a safe and effective screening method for fetal chromosomal aneuploidies. Here, we report an improved sequencing method achieving significantly increased throughput and decreased cost by replacing laborious sequencing library preparation steps with PCR employing a single primer pair. Using this approach, samples containing as little as 4% trisomy 21 DNA could be readily distinguished from euploid samples.

    摘要: The identification of mutations that are present in a small fraction of DNA templates is essential for progress in several areas of biomedical research. Though massively parallel sequencing instruments are in principle well-suited to this task, the error rates in such instruments are generally too high to allow confident identification of rare variants. We here describe an approach that can substantially increase the sensitivity of massively parallel sequencing instruments for this purpose. One example of this approach, called "Safe-SeqS" for (Safe-Sequencing System) includes (i) assignment of a unique identifier (UID) to each template molecule; (ii) amplification of each uniquely tagged template molecule to create UID-families; and (iii) redundant sequencing of the amplification products. PCR fragments with the same UID are truly mutant ("super-mutants") if =95% of them contain the identical mutation. We illustrate the utility of this approach for determining the fidelity of a polymerase, the accuracy of oligonucleotides synthesized in vitro, and the prevalence of mutations in the nuclear and mitochondrial genomes of normal cells.

    摘要: The present invention provides, inter alia, methods for treating or ameliorating an effect of a solid tumor present in a human. These methods include administering intratumorally to the human a unit dose of C. novyi, preferably C. novyi NT, colony forming units (CFUs), which contains about 1 x 10 3 -1 x 10 7 CFUs suspended in a pharmaceutically acceptable carrier or solution. Methods for debulking a solid tumor present in a human, methods for ablating a solid tumor present in a human, a method for microscopically precise excision of tumor cells in a human, methods for treating or ameliorating an effect of a solid tumor that has metastasized to one or more sites in a human, unit doses of C. novyi, preferably C. novyi NT, CFUs, and kits for treating or ameliorating an effect of a solid tumor present in a human are also provided.

    摘要翻译: 存在于一小部分DNA模板中的突变的鉴定对于生物医学研究的若干领域的进展是必不可少的。 尽管大规模并行测序仪器原则上非常适合于此任务,但这些仪器的错误率通常太高,以至于无法确定罕见变体。 我们在这里描述了一种可以大幅度提高大规模并行测序仪器的灵敏度的方法。 这种方法的一个例子叫做安全测序系统(Safe-Sequencing System)的“Safe-SeqS”,包括(i)为每个模板分子分配一个唯一标识符(UID) (ii)扩增每个独特标记的模板分子以产生UID家族; 和(iii)扩增产物的冗余测序。 具有相同UID的PCR片段确实是突变体(“超级突变体”),如果其中95%含有相同的突变。 我们说明了这种方法用于确定聚合酶保真度的效用,体外合成的寡核苷酸的准确性以及正常细胞核和线粒体基因组突变的发生率。
