Docetaxel, and PTC-209 were purchased from selleckchem (Houston, TX USA). The ChIP-grade anti-BMI1 antibody was obtained from Millipore (Bedford, MA, USA). We used following antibodies: anti-BCL2, anti-BMI1, anti-mitochondrial protein, anti-PCNA, anti-Cyclin D1 (Cell Signaling, Danvers, MA), anti-P16, anti-c-MYC (Abcam, Cambridge, MA) and anti-VEGF (SantCruz, CA). We used following plasmids pTK-TCF-Luc (Upstate Laboratories, Lake Placid, NY); pGL3-MMP2, pGL3-VEGF, pGL3-MYC (Addgene, Cambridge, MA) and pGL3-BMI1 (gifted by Goberdhan Dimri, George Washington University, Washington DC).
Transfections, luciferase reporter activity, Immunostaining, Immunoblot analysis, 3[H]-thymidine incorporation, cell growth, migration and invasion assays were performed as described previously (13 (link), 14 , 16 (link)).
