Gene expression profiles for these samples were investigated using Affymetrix arrays. Experiment Overall Design: MDA-MB-231 human breast cancer cells were stably transfected with human sFRP1 encoding vector or empty vector as control. After the selection with antibiotics, three clones of MDA-MB-231/sFRP1 and three clones of MDA-MB-231/control were selected. These six clones were cultured individually in DMEM 10% FCS with 1mg/ml G-418. When cells reached 70-80% confluence, RNA was isolated from the cells. In parallel, the three clones of MDA-MB-231/sFRP1 and the three clones of MDA-MB-231/control were pooled respecbiostudies-othertranscription profiling by arrayEurocanPlatformOakeley EdwardfalseTranscription profiling of human MDA-MB-231 breast cancer cells in vitro and in vivo as xenografts to assess the effect of ectopic expression of sFRP1RNA was isolated from ectopically sFRP1-expressing MDA-MB-231 cells and control MDA-MB-231 cells and as well from tumor lysates arising from these cells as nude mouse xenograft.
