Pre-computed Pearson correlation coefficients by disease?

I am looking to extract the Pearson correlation coefficient for gene expression vs. RNAi sensitivity for all genes (GeneA Gene Effect vs GeneA Expression, GeneA Gene Effect vs. Gene B Expression, GeneA Gene Effect vs. Gene C Expression, and so on…) using cell lines from a given disease (only glioblastoma, for example). Are the P coefficients computed on the fly (depending on filtering) or do these lie in a data file somewhere that can be downloaded? An ideal output would be a matrix of gene ID with Expression as columns and Gene Effect as rows. I’m using PRMT5/MTAP in glioblastoma in the below screen capture as an example of what I am trying to extract for all combinations of genes. Thanks!
