In that study, PyMT and Neu murine tumour cells derived from breast adenocarcinoma cells and transduced with Adenovirus-type 5 vectors produced 788 and 1204 ng 106 cells−1 24 h−1, respectively, of IL-12, and 32 and 51 ng 106 cells−1 24 h−1 of IL-2 (Emtage et al, 1999). The gene discussed is IL2; the disease is neoplasm.
