Baseline expression of interferon-stimulated genes (ISGs) and interferon β in human fibroblasts and sarcomas. mRNA was harvested from uninfected cultures of human fibroblasts (hFibro), VSV-resistant synovial sarcoma SW982, and three VSV-susceptible sarcomas (ESFT A673, Osteosarcoma SJSA1, and MPNS tumor S562-TY). mRNA concentrations for two ISGs, MxA (A) and ISG-15 (B), and for IFN-β (C) were measured from triplicate samples by quantitative RT-PCR and normalized to β-actin. Error bars, SEM.
