Fig. 3. Characteristics of L-cells stably transfected with pcDNA3.1-CAR^GSIV, CAR, or –eGFP. (A) Elevation of reporter gene expression in CAR and CAR^GSIV stable cell lines in comparison to GFP 2 days after infection with an adenovirus containing the ß-galactosidase gene (*P<0.001). (B) Growth comparison between these cell lines by protein concentration (*P<0.001). (C) Relative increase in cell count at day 5 versus day 3 (*P<0.00001). CAR significantly reduced cell growth in comparison to CAR^GSIV and eGFP stable cells.
