B7-H3 promotes chemoresistance of CRC cells via STAT3/CDC25A. (A) The CRC cell proliferation rates upon silencing STAT3/CDC25A in control or B7-H3-overexpressing CRC cells were determined using the CCK8 assay and are presented as the mean ± SD of three independent experiments. (B) The effect of silencing STAT3/CDC25A on the colony formation assay in control or B7-H3-overexpressing CRC cells treated with 5 μM L-OHP for 2 h. (C) The LDH level upon silencing STAT3/CDC25A in control and B7-H3-overexpressing CRC cells were determined with the LDH assay and are presented as the mean ± SD of three independent experiments. **P<0.01, *P<0.05.
