Fig. 2From: IGFBP5 increases cell invasion and inhibits cell proliferation by EMT and Akt signaling pathway in Glioblastoma multiforme cellsIGFBP5 expression levels in different cell lines and IGFBP5 were depleted by siRNA. a Western blot analysis demonstrated that U251 and G1 cell lines express high levels of IGFBP5 protein. b qPCR showed that siRNA of IGFBP5 downregulated the IGFBP5 expression in study group. c Western blot confirmed that IGFBP5 expression had been downregulated using siBP5-b and siBP5-c. **P < 0.01, ***P < 0.001 and ****P < 0.0001Back to article page
