DNA/RNA Delivery Core

在国家发改委的第一个周期中，DNA/RNA传递核心被参与的国家发改委调查人员广泛使用 在皮肤生物学研究中。这个核心已经为研究人员提供了Lenti/逆转录病毒的表达载体 在皮肤细胞中过度表达或沉默基因以及表达记者。核心还执行了单元 为研究人员提供关于病毒感染的培训和咨询，并提供关于病毒DNA/RNA传递的培训和咨询。新一代 表达shRNA和MLRs的慢病毒一直是国家发改委要求最多的服务 成员和试点项目和可行性项目。在过去的几年里，核心戏剧性地扩大了 向量库。Core现在提供了广泛的载体用于表达：(I)带有单个或 双启动子、多顺反子设计、C/N末端蛋白标签和荧光融合蛋白；(Ii)茎环 ShRNA/MIR前体或功能活跃的成熟RNAi寡核苷酸沉默基因/蛋白质表达；(Iii) 用于细胞跟踪(使用荧光或发光标记)、转录因子研究(荧光素酶)的记者 记者)和高通量(HTP)筛选。我们预计将进一步扩大和多样化 以及向用户提供未来五年最强大的技术 在快速发展的病毒传递领域的方法。与发改委和国家臭氧机构的其他核心合作， 我们开发了用于特殊应用的病毒和方案，例如感染体内的原代角质形成细胞 RAFT培养；体外和体内细胞追踪；化学文库的筛选；以及细胞因子和 具有生物活性的调节剂。国家发改委经常要求核心小组进行个别磋商 成员在他们的研究项目的技术方面提供帮助。董事和核心的专业知识 专家将继续帮助研究人员评估他们感兴趣的基因/蛋白质在其中发挥的作用 皮肤。我们将继续确保核心提供的服务、培训和故障排除技能 以及病媒和病毒库，提高了国家发改委的能力和成本效益 研究人员，从而加强现有的合作企业，并吸引新的研究人员到 皮肤生物学领域。

In the first cycle of this SDRC, the DNA/RNA Delivery Core was widely used by SDRC investigators involved in cutaneous biology studies. This Core has provided researchers with expression vectors, lenti/ retroviruses to overexpress or silence genes and to express reporters in skin cells. The Core also performed cell infections for researchers and provided training and consultations on viral DNA/RNA Delivery. Generation of lentiviruses expressing shRNA and MlRs have been the most highly sought services requested by SDRC members and Pilot and Feasibility projects. During past few years, the Core dramatically expanded the vector repository. The Core now offers a broad panel of vectors for expression of: (i) cDNA with single or dual promoters, polycistronic design, C/N terminal protein tags and fluorescent fusion proteins; (ii) stem-loop precursors of shRNA/MiR or functionally active mature RNAi oligos to silence gene/protein expression; (iii) reporters for cell tracking (with fluorescent or luminescent markers), studies of transcription factor (Luciferase reporters), and high throughput (HTP) screening. We anticipate further extension and diversification of the vector repository in the next five years, as well as provision to users of the most powerful technical approaches in the quickly progressing field of viral delivery. In collaboration with other SDRC and NU Cores, we developed viruses and protocols for special applications, such as infection of primary keratinocytes within raft cultures; in vitro and in vivo cell tracking; screening of chemical libraries; and production of cytokines and biologically active regulators. Individual consultations by the Core have been frequently requested by SDRC members to aid in technical aspects of their research projects. The expertise of the Directors and the Core specialist will continue to help investigators in evaluating the roles that their genes/proteins of interest play in skin. We will continue to ensure that services, training and troubleshooting skills provided by the Core, as well as vector and viral stocks libraries, lead to increased capabilities and cost-effectiveness for SDRC investigators, thus strengthening the existing collaborative ventures and attracting new researchers to the field of cutaneous biology.
