(a-f) ORCTL3, ORCTL3ER, Luc, and Caspase 2 were transfected into the H-ras-, myc-, E6-, and P53-transformed CV-1 cells as well as into E1A- and empty vector-transfected CV-1 cells. Apoptosis was monitored after 24 hours. Data represent the means of independent experiments ± SD, (n=3). (g) ORCTL3 is more efficiently expressed in WT CV-1 compared to transformed CV-1 cells. WT and transformed CV-1 cells transfected with HA-tagged ORCTL3 were harvested 24 hours after transfection and stained with an Alexa-488 conjugated antibody against HA. Data represent the means of independent experiments ± SD, (n=3). (h) Cells transfected with a plasmid expressing GFP were harvested 24 hours after transfection and assayed by flow cytometry to quantify the GFP signals. Each bar represents the mean ± SD, (n=3).
