DDX21 and colorectal carcinoma: Similarly, in vitro rescue experiments revealed that DDX21 overexpression reversed the facilitated effect on CRC molecular characteristics including cell proliferation ability, cell colony formation capacity, cell migration ability, and apoptotic rates in both SW620 and SW480 cells assayed by cell number monitoring (Figure 3E), CFA assay (Figure 3F), flow cytometry analysis (Figure 3G) and Trans-well (Figure 3H and Supplementary Figure 3B), respectively.
