Western Blot: p53 Antibody (Pab DO-1) - BSA Free [NBP2-50538] - DCQ reduces HIF-1 alpha through different mechanisms in MCF-7 & MDA-MB-231. (A) MCF-7 cells were transfected with siRNA against p53 & ctrl siRNA (scrambled sequence) using lipofectamine 2000. After 24 hours, cells were treated with DCQ (5 μM) for 6 hours under hypoxia. Whole cell lysates were prepared, & blots were probed against indicated antibodies. (B) MCF-7 cells were transfected with siRNA against p53 & ctrl siRNA (scrambled sequence) using lipofectamine 2000. Transfected cells were treated with DCQ (5 μM) for 6 hours under hypoxia. The extent of DNA fragmentation was determined by TUNEL assay 24 hours later using flow cytometry. One-way ANOVA was used to compare DCQ-treated versus control & statistical significance of p < 0.05 is indicated by *. (C) Whole cell lysates were prepared after pretreating MCF-7 & MDA-MB-231 with the proteasome inhibitor MG132 (3 μM) then treated with DCQ, & blots were probed for HIF-1 alpha. Results are from three independent experiments. (D) Whole cell lysates of MCF-7 were prepared after 6 hours of exposure to DCQ (5 μM) under normoxia or hypoxia, & blots were probed for p-AKT, mTOR, p-mTOR & GAPDH.

Western Blot: p53 Antibody (Pab DO-1) - BSA Free [NBP2-50538] - DCQ induces DNA damage & apoptosis via reactive oxygen species. (A) Whole cell lysates of MCF-7 & MDA-MB-231 were prepared after 6 hours of exposure to DCQ (5 μM) under normoxia or hypoxia, & blots were probed for p-H2AX, p53, p-p53, p21, HIF-1 alpha & GAPDH. Results are representative of three independent experiments. (B) MDA-MB-231 & MCF-7 cells were pretreated with 1 mM Vitamin E or DTT for 2 hours followed by 25 min incubation with 10 μM CM-H2DCFDA dye. Cells were washed with PBS & treated with DCQ for 1 hour under normoxia or hypoxia, after which cells were harvested & the amount of DCF fluorescence was analyzed by flow cytometry. Each percentage is the average ± SE of three independent experiments. (C) MDA-MB-231 & MCF-7 cells were pretreated with 1 mM Vitamin E or DTT for 2 hours followed by 6 hours treatment with DCQ under normoxia or hypoxia. After 24 hours, the extent of DNA fragmentation was determined by TUNEL assay & measured by flow cytometry. One-way ANOVA was used to compare DCQ-treated versus control & statistical significance of p < 0.05 is indicated by *. (D) Whole cell lysates of MCF-7 & MDA-MB-231 were prepared after 6 hours of exposure to DCQ (5 μM) under normoxia or hypoxia, & blots were probed for HIF-1 alpha & GAPDH.
