ZBTB7A and glioblastoma: We examined the tumorigenicity of U87 cells, a cell line with relatively high expression of ZBTB7A, after transfection with ZBTB7A shRNA or control shRNA lentiviral plasmid (Supplementary Fig. 1a; Control shRNA and shZBTB7A#1–6) to determine the probable role of ZBTB7A in GBM development.
