來自于文章:Multi-omics profiling reveals distinct microenvironment characterization and suggests immune escape mechanisms of triple-negative breast cancer 里面提到了數(shù)據(jù):
The sequencing data is also available in GSE118527 (OncoScan), GSE76250 (HTA 2.0) and SRP157974 (WES and RNAseq)
然后同樣的作者2016年在plos one 發(fā)文重新修訂了 之前的分類,變成4類:(TNBCtype-4) tumor-specific subtypes (BL1, BL2, M and LAR)
發(fā)表在Clin Cancer Res 2015 ,貝勒醫(yī)學院研究小組的 Burstein 等人對自己的數(shù)據(jù),198個TNBC病人芯片表達矩陣,使用80個核心基因進行分組,得到4個TNBC的亞型。
發(fā)表在 Breast Cancer Research (2015) :Gene-expression molecular subtyping of triple-negative breast cancer tumours: importance of immune response,數(shù)據(jù)在 GSE58812, 法國研究團隊的等人使用 適應性的Fuzzy-clustering 把107個TNBC 患者分成3類。
3個是 for MDSC,angiogenesis, and antigen presentation machinery
使用GSVA包的ssGSEA算法,對z-score后的RNA-seq表達矩陣進行分析。有趣的是作者提供了RPKM矩陣哦,The RNA-seq FPKM data have been deposited at figshare (https:///10.6084/m9.figshare.7306364.v1). 所以理論上可以重現(xiàn)作者的分析。
可以把病人分成3組不同的免疫狀態(tài),主要是看 IFNG, PD-L1, PD-1, and CD8 基因的表達
繼續(xù)看這里作者使用NBclust分類,可以把病人隊列劃分為3個類群。
分型具有生存效果
RNA-seq和HTA2.0芯片的表達數(shù)據(jù)的比較
這里使用ComBat算法抹去兩個平臺的差異
在TNBC隊列驗證
同樣也是分成3類:
在METABRIC隊列驗證
也可以區(qū)分成為3類,圖片在文章里面的附件!
