Anisomycin affects the expression of PDGFRs and Notch pathway components in ovarian cancer stem cells. (A) mRNA expression levels of key factors of the Notch pathway, PDGFRA and PDGFRB in ovarian cancer tissues with more and less CD44+/CD133+ HuOCSCs. **P<0.01. (B) mRNA expression levels of key factors of the Notch pathway, PDGFRA and PDGFRB in CD44+/CD133+ HuOCSCs following anisomycin treatment. **P<0.01 vs. non-treated (n=4). (C) Western blotting results from the experimental groups of panel A. (D) Western blotting results from the experimental groups of panel B. PDGFR, platelet-derived growth factor receptor; HuOCSCs, human ovarian cancer stem cells; DLL1, δ-like canonical Notch ligand 1; HES1, hes family bHLH transcription factor 1; RBPJ, recombination signal binding protein for immunoglobulin κ J region.
