BSG and astrocytoma (excluding glioblastoma): We established two stable knockdowns of CD147, with a CD147-specific short hairpin RNAs (siCD147) targeting the 3′ UTR of cellular CD147 mRNA, and two corresponding non-specific RNAi stable cells as controls (siControl) via lentiviral-based transduction of Human astrocytoma U251 cells (U251 cells) and Human foreskin fibroblasts cells (HFF cells).
