Then, CRC cells infected with control or LDB1 shRNA-derived lentivirus were cultured for 0, 1, 2, 3 or 4 days, and the CCK-8 assay showed that silence of LDB1 could markedly inhibit cell growth in both of HCT116 (Figure 3B) and DLD1 cells (Figure 3C). This evidence concerns the gene LDB1 and colorectal carcinoma.
