Identification of transcription factor - gene regulation information

Question

[Vasu]

I have seen many databases like TRANSFAC, HTRIdb, TRRUST etc..from where I can download information about TF-gene regulation in different cancer datasets.

But I'm interested in finding TF-gene regulation information specific to the samples I'm working with. I have ER+ samples of TCGA Breast cancer dataset. I would like to identify TF-gene regulation of only these samples. How to do that?

Any approaches or ideas for this? Any help is appreciated. thanq
