I did differentially expression (DE) analysis on TCGA datasets and identified several DE genes. During my paper review, one of reviewers insisted on the validation of DE genes by experiment.
To be honest, I do not have place, equipment and so on to do this validation. So I have a Plan-B which is validated at least some of DE genes which really exist in other datasets or databases.
How do you think of this idear?
Do you have some existed databases or tools to query or download the DE genes in other datasets especially for cancer types in TCGA?
Thanks in advance
