For my computational cancer model using RNA-Seq data, I am going to use TCGA as a discovery cohort. Since ICGC or GDC have great overlap with TCGA data, I want to find independent databases as validation cohort. I can find several RNA-Seq data on cancer cell lines, such as CTRP, TARGET, CCLE, but can't find cancer patient data. If you have an idea about where go to for this, can you please let me know?
Thank you guys for your time and effort!
