I am looking for co expression pattern of few selected genes in specific cancer vs normal patients samples. It can be either RNA seq or micro array. I found number of databases which claim that they can give co-expression of gene- next bio, geneinvestigator, oncomine and list goes on however most of them either give z score or co-expression p value in one particular data set. Further none of them provide normalized values across different data sets, which may allow me to take that matrix and analyze outside. Even NCBI GEO will allow me to analyze a particular one set at a time. Before I start scanning each data set (which is a lot of work) I was wondering if there is any expression database which can out put normalized expression values across different platforms for normal vs cancer samples.
