DESCRIPTION (provided by applicant): Completion of the human genome and the advent of expression profiling have permitted comprehensive characterization of the transcriptional signatures of different disease states. Quantitative fluorescent real-time polymerase chain reaction-based methods have emerged as a powerful tool in molecular diagnostics as they combine extraordinary dynamic range of quantification and superior specificity. Despite the remarkable advances in real-time fluorescence quantification techniques, this technique has yet to gain widespread application in the analysis of gene expression fixed paraffin-embedded tissues, which is the most common way in which biopsy material is archived. In the R41 phase of this fast-track application, we will establish the utility of a simple approach to the performance of quantitative RT-PCR on RNA derived from formalin-fixed paraffinembedded tissue. The technique is advantageous in that it is simple and compatible with the design of PCR for short amplicons, without compromising target specificity. By the end of the R41 phase of this project, we would have established the feasibility, reproducibility and robustness of our quantitative real-time RT-PCR approach on RNA derived from formalin-fixed paraffin embedded tissue material. These studies will serve as the foundation for the gene expression profiling studies evaluating the predictive power of a previously identified set of ~30 genes to predict the transformation of follicular lymphoma to an aggressive large B-cell lymphoma in phase II.

描述（由申请人提供）：人类基因组的完成和表达谱的出现已经允许对不同疾病状态的转录特征进行全面表征。基于定量荧光实时聚合酶链反应的方法已经成为分子诊断中的有力工具，因为它们联合收割机了非凡的定量动态范围和上级的特异性。尽管在实时荧光定量技术的显着进步，这种技术还没有获得广泛的应用，在基因表达固定石蜡包埋组织的分析，这是最常见的方式，活检材料存档。在R41阶段的快速通道的应用，我们将建立一个简单的方法来执行定量RT-PCR的RNA来自福尔马林固定石蜡包埋组织的效用。该技术的优点在于它简单并且与短扩增子的PCR设计相容，而不损害靶特异性。到本项目的R41阶段结束时，我们将建立我们的定量实时RT-PCR方法对来自福尔马林固定石蜡包埋组织材料的RNA的可行性、再现性和稳健性。这些研究将作为基因表达谱研究的基础，评估先前确定的一组约30个基因的预测能力，以预测滤泡性淋巴瘤向II期侵袭性大B细胞淋巴瘤的转化。
