Fig. 1From: Efficacy of a novel double-controlled oncolytic adenovirus driven by the Ki67 core promoter and armed with IL-15 against glioblastoma cellsExpression of IL-15 in GBM cells treated with Ad5-Ki67/IL-15. a–d ELISA was used to measure IL-15 levels in conditioned media that different glioma cells were treated with Ad5-Ki67/IL-15 (MOI = 40) for 24, 48, 72, and 96 h. Untreated conditioned medium was used as a control. e–h IL-15 gene expression in GL261, U251, U87 and primary cells BT-01 treated with Ad5-Ki67/IL-15 for 72 h by qPCR.
