The GRID signature from Decipher array data assesses AR activity in prostate tumors and models whether a tumor is basal or luminal.

“but in addition to doing that which is looking at about 20 or 22 kind of genes that are associated with aggressiveness in prostate cancer we also kept all the data from the other 40 or so 40,000 different spots on the on the apy array and then that's how we built this ar ar signature so you can actually get access to through your physician what we call the grid signature and within the grid you can actually look at the AR activity of your individual tumor you can kind of model whether or not the tumor is a more basilik a more luminal like tumor”
