Figure 4. Inhibition of lumen formation of MCF7/CEACAM1-4S cells by RNAi to calpain-9.

Figure 4

A: MCF7 cells transfected with wild type CEACAM1-4S treated with RNAi control oligo in Matrigel for 6d and examined by phase contrast microscopy (50x). After examination of 200 acini, lumen formation was 67% compared to 81% for lipofectamine treated controls or 93% for untreated controls (Table 2). B: Same as above treated with RNAi oligo 1 for CAPN9 (30% lumen formation, Table 2).
