In isotypecontrol antibody treated mice NAF COX-2KD grew poorly in only two of six injections.In contrast, six of six NAF COX-2KD tumors grew in CD8+ depleted mice,similar to NAF nt control cells (Figure 6B), and were markedlylarger at necroscopy (four weeks after tumor injection; Figure 6C). The gene discussed is CD8A; the disease is neoplasm.
