Study the pathological features of diseases using induced pluripotent stem cells derived form patient39;s somatic cells
The limited experimental access to disease-affected human tissues has severely impeded the elucidating of molecular mechanisms underlying disease development. Generation of induced pluripotent stem cells (iPSCs) by over-expression of defined transcription factors in somatic cells, in particular in those from patient somatic cells, presents an attractive and promising approach to model the early stages of diseases in vitro and to screen novel biomarkers as well as therapeutic medicines. Recently, many research groups have independently reported that patient-specific iPSC-derived cells recapitulated multiple features of pathological events of a particular disease, offering experimental evidence of utilizing patient-specific iPSCs to model diseases and reevaluate the current therapies. We have derived iPSC lines using somatic cells of patients suffering from Klinefelter's Syndrome (KS) and Alzheimer's Disease (AD) and explored the possibility to use these iPSC lines to recapitulate the pathological features of the diseases. Our results show that patient's specific iPSC lines provide good opportunity to study the development and treatment of diseases.
晶芯® 人类长链非编码RNA芯片V3.0的设计及在疾病研究中的应用
长链非编码RNA (lncRNA)以RNA的形式在多种层面上,通过影响染色质状态,RNA转录和翻译层面调控基因的表达。近年研究者非常关注lncRNA在各种生物学过程和疾病过程中所起到的作用,形成了新的研究热点。 博奥生物与中科院生物物理所陈润生院士研究组,基于已经公布的大量lncRNA数据库及实验室发现的800多条中等长度的非编码RNA,推出了自主设计的lncRNA芯片。继成功推出lncRNA V1.0 和 V2.0 芯片基础上,鉴于当前lncRNA 研究的快速进展,收集和更新lncRNA 序列信息,经过严格的序列筛选和整合,推出了新一代的晶芯lncRNA V3.0 芯片服务。最新的V3.0芯片包括约3.8万条lncRNA和约3.4万条mRNA探针,可以同时针对lncRNA和mRNA进行检测。在充分保证探针容量和重复数量(lncRNA和mRNA检测探针均重复2次以上)的前提下,降低了芯片成本和实验费用。在检测成本和检测准确性之间达到较好的平衡点。 通过lncRNA芯片检测,研究人员能够迅速获得与特定生物学过程或者疾病相关的lncRNA的表达变化,从而发现与特定生物学过程相关的lncRNA,寻找与疾病相关的lncRNA。
