PDCD4 is downregulated in CRC clinical tissues. (A) Compared with in adjacent normal tissues, PDCD4 mRNA expression was significantly decreased in CRC tissues. (B) Compared with in adjacent normal tissues, PDCD4 protein expression was significantly decreased in CRC tissues. Data were normalized to the GAPDH control. Results are expressed relative to the normal control levels that were assigned a value of 1. Data are presented as means ± SD. **P<0.01. PDCS4, programmed cell death factor 4; CRC, colorectal cancer.
