I am using the TCGA portal to get mRNA expression data for various cancer studies (e.g. lung, liver, thyroid etc). We have been on a lookout for control/normal samples for the cancer studies on TCGA. On the website we could find case/tumor samples but couldn't find any control samples.
Does anyone know or have used control/normal samples from TCGA and can point me to it? Or do you know of a good resource (preferably using RNASeq V2 RSEM normalized expression values or z-scores) for control/normal samples in tissues like Lung, Liver, Thyroid etc. (basically all the fore-gut tissues)?
