More importantly, in the T24 and 5637 cells that were co‐transduced with Lv‐sh‐CERCAM and lv‐CERCAM, the tumor‐suppressive effects of CERCAM knockdown on cell viability, DNA synthesis, cell invasion, and related markers were partially impaired by CERCAM overexpression (Figure 2A,D). This evidence concerns the gene CERCAM and neoplasm.
