  Toward Efficient Analysis of Mutations in Single Cells from Ethanol-Fixed, Paraffin-Embedded, and Immunohistochemically Stained Tissues

  摘要：

  only a few studies have demonstrated successful molecular analysis after whole genome amplification using single cells dissected from paraffin-embedded tissues. The results in these studies were limited by low-amplification efficiency and high rates of allele dropout. In the present study, the amplification rate using a thoroughly modified primer extension and preamplification-PCR protocol was improved significantly for single cells microdissected from paraffin-embedded and immunohistochemically stained tissues. Tissue fixation with ethanol (85%) and the addition of 0.2 mmol/L EDTA helped to achieve an amplification rate between 67% (segments 200 to 400 bp) and 72% (segments <200 bp). Normal tissue sections were immunohistochemically double stained for overabundance of p53 protein and proliferating cell nuclear antigen. Microdissection of single cells was performed with a manual micromanipulator equipped with a Tungsten needle. Sequence analysis of the TP53 gene was performed after improved primer extension preamplification-PCR and multiplex PCR from single microdissected cells. The rate of allele dropout was at least 68%. These technical advances facilitate routine mutation analysis using a single cell or a few cells microdissected from routinely processed paraffin-embedded normal and tumor tissues. Allele dropout still represents a serious problem in single-cell mutation analysis, especially in samples with limited template DNA and prone to DNA damage.

  N-（苄氧羰基）甘氨酸酯和酰胺作为新型抗惊厥药。

  摘要：

  甘氨酸是一种小的中性氨基酸，在体内表现出弱的抗惊厥活性。最近，研究表明，在最大电击（MES）测试（一种甘氨酸失活的惊厥模型）中，N-（苄氧羰基）甘氨酸（1）对抗癫痫发作的作用优于甘氨酸。在本研究中，已经制备了一系列的1的酯和酰胺衍生物以及N-（3-苯基丙酰基）甘氨酸的酯（5）。在MES测试以及几种化学诱导的癫痫发作模型中对化合物进行了评估。在所研究的衍生物中，N-（苄氧基羰基）甘氨酸苄酰胺（16）是最有效的化合物，在MES试验中表现出与药物苯妥英相当的抗惊厥活性。腹腔注射后30分钟和3小时测定的中位有效剂量（ED50）为4.8和11.6 mg / kg 行政管理。化合物16还可以在不同的化学诱导模型（例如士的宁，3-巯基丙酸和戊四唑测试）中有效抑制强直性癫痫发作。此外，在150 mg / kg的剂量下，在转子试验中，此处研究的化合物未显示急性神经毒性。结论是，N-（苄氧基羰基）甘氨酸酰胺，特别是16种，是有效的抗惊厥药。
