I'm having a hard time retrieving the most expressed genes in a cell line. One of the databases I've found has values for a lot of genes in 60 different cell lines and it seems the data is obtained using GC-RMA. The data is available here in the file NCI60_U133A_20070815.raw.csv.
My problem is what does the values actually represent? Would it be correct to assume the genes with high values are the ones most expressed in the corresponding cell line?
I've found a short explanation on why there is no unit definition on the page here.
Here is a snapshot of the file:
