Table 2 Unique UPRs induced by CPA in GL261(B6) compared to LLC and B16F10 tumors. Shown are the 47 UPRs unique to CPA-treated GL261(B6) tumors identified in Additional file 4: Table S3G, classified into 4 categories based on their functions. Group 1 UPRs are expected to contribute to the anti-tumor response, group 2 UPRs counter the anti-tumor response, and the actions of group 3 UPRs depend on cell context. Only two of the UPRs are associated with the glioma-specific lineage of GL261 tumors (group 4)
