To investigate the molecular mechanism underlying HCMV pp71 induction of SCF expression in glioblastoma, we generated a pp71-expressing stable U87 glioma cell line (figure S3A) and interrogated changes in gene expression between pp71- expressing and control cells using Affymetrix arrays, followed by Ingenuity pathway analysis (IPA) (raw Affymetrix data is available at the following link http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?token=hxutbkksiwaschc&acc=GSE42618). Here, KITLG is linked to glioma.
