How to get basal-like breast cancer data?

Question

[BioMed]

Dear all,

I wonder is there any specific database for basal-like breast cancer (gene expression, RNAseq,... in vivo and in vitro)?

In addition, I want to ask is there any difference between between "basal-like breast cancer" and "basal-like triple negative breast cancer"? As far as I know, not all cases of basal-like breast cancers are triple negative breast cancers and vice versa. However, if a specific tumor is basal like triple negative, it should belong to basal-like breast cancer group in general. Is it correct?

Thank you in advance for your help.
