Verification of knockdown of SPARC expression by lentivirus-mediated RNA interference. (A) GFP expression images showed shRNA delivery efficiency. (Magnification × 200). (B) SPARC protein expressions of SPARC shRNA infected cells, control shRNA infected cells and non-infected cells as measured by Western blot. (C) SPARC mRNA expressions of SPARC shRNA infected cells, control shRNA infected cells and non-infected cells as measured by q-RT-PCR. (D) SPARC protein expressions of SPARC shRNA infected cells, control shRNA infected cells and non-infected cells as measured by ICC staining (Magnification ×200). *P<0.05 versus control.
