Construction of MV-E:A viruses and evaluation of their cytopathic activity. (A) Human/mouse E:A or enhanced GFP were cloned into the mluI/AatII restriction site of MV-NIS to create the MV-hE:A, MV-mE:A and MV-GFP viruses. The human IL-2 signaling peptide (hIL-2) appended to the E:A proteins results in their secretion from the infected cells. The oncolytic activity of these new viruses was compared by infecting (B) D283med and (C) D425med cells at an MOI of 0.1 and measuring their viability over the next three days by MTT assay. Viral production assays were similarly conducted by infecting (D) D283med and (E) D425med at MOI 0.1 and analyzing cell lysates collected at the listed timepoints. Viral titers were determined by the TCID50 method.
