Reader Comments:
总体撰文较好,建议如下:
1、全文仅适用基于TCGA数据库的测序数据进行分析,缺乏使用其他数据集对基因的预后和免疫浸润情况进行验证;
2、蛋白互作分析中使用String数据库,然而String得到蛋白互作结果并非基于TCGA的测序表达谱,应将String得到互作蛋白和TCGA数据(或其他数据集)中共表达相关性强的基因结合分析;
3、小问题:既然谈到了突变分析,为何不分析PDE2A突变亚型的预后差异和临床相关性?图3中仅仅探讨了PDE2A表达与肿瘤stage分期的关系,为何不补充与肿瘤TNM、age、MSI的相关性?图6对TIMER的结果表述不清晰且没有意义(“与免疫细胞呈正相关或负相关”,代表什么,说明什么?)
深入阐明上述问题,文章内涵将提升
