<p>A. Anchorage-independent growth in soft agar of BAR-T p53 RNAi cells expressing H-Ras^G12V. No colonies are observed for the vector-containing control cells, whereas a number of colonies are observed (circled) for the BAR-T p53 RNAi cells expressing H-Ras^G12V (clones R1 and R2). Selected colonies for clones R1 and R2 are shown at higher magnification (4X). B. Quantification of colonies for the vector-containing control cells and for the BAR-T p53 RNAi cells expressing H-Ras^G12V (clones R1 and R2). The SEG1 cancer cells formed 325.3±14.4 SEM colonies and served as a positive control.
