在这项研究中,我们对十项可公开可用的基准测试进行了全面的荟萃分析,该测试评估了使用RNA-SEQ数据评估基因融合检测工具的性能。我们的分析集中在关键性能指标上,包括灵敏度,精度和F1分数。我们评估了工具在不同数据集中的性能。我们检查了数据集特征的影响,例如样本类型(真实或模拟)和读取长度,以及结果对结果的其他样本和测序参数。除了评估绩效外,我们还分析了基准测试的组织和设计,突出了诸如数据集的清晰描述,详细的仪器参数和透明方法。但是,我们还确定了常见的陷阱,包括不足的可重复性信息,数据集的多样性和缺乏广泛接受的黄金标准数据集。这些限制使得很难始终如一地评估工具并跨基准进行比较。通过综合这些发现,我们为未来的基准项目提出了建议,强调了标准化的需求,提高透明度和健壮真理集的发展。本研究旨在帮助社区创建更可靠和可重复的基准测试,最终加速了用于临床和研究应用的基因融合检测工具的开发和评估。

As the 26 first approach to develop a septin filament targeting agent, we optimized the structure of 27 Forchlorfenuron (FCF), a known plant cytokinin to generate UR214-9, which contrary to FCF, 28 causes septin-2/9 filamental structural catastrophe in cancer cells without altering cellular septin 29 protein levels. In-silico docking using septin-2/septin-2 dimer complex showed that UR214-9 30 displaced the guanine carbonyl oxygen from the GDP binding domain and showed increased 31 binding energy than FCF(-8.59vs-7.21). UR214-9 reduced cancer cell growth, downregulated 32 HER2/STAT-3 axis and controlled growth of HER2+ pancreatic, breast and ovarian cancer 33 xenografts in NSG mice and enhanced response of Herceptin against HER2+breast cancer 34 xenograft. Transcriptome analysis of UR214-9 exposed cells demonstrated significant 35 perturbation of <20 genes compared to afatinib which impacted >1200 genes in JIMT-1 breast 36 cancer cells indicating target specificity and non-transcriptional functions of UR214-9. In summary, 37 disrupting septins via UR214-9 is a new approach to control the growth of HER2+ malignancies. 38 39 Introduction 40 41 Septins are a family of GTP-binding cytoskeletal proteins that participate in cytokinesis, 42 cell migration, chromosomal dynamics and protein secretion. Septins hetero-oligomerize to 43 generate scaffolding filaments, bundles, and rings within cells 1-11 . Additionally, septins are a 44 critical cytoskeletal component that regulate the function of tubulin and actin. Altered septin 45
