Fig. 1. POTEE is upregulated and predicts poor clinical outcome in CRC patients.

a The relative mRNA levels of POTEE in 20 paired CRC and adjacent normal tissues. Results are shown as mean ± SD. *P < .05, **P < .01, ***P < .001, based on Paired t-test. b Western blots of POTEE protein in 20 pairs of CRC tissues, GAPDH was loaded as a control. Relative protein expression were measured by Image J and shown as mean ± SD. *P < .05, **P < .01, ***P < .001, based on Paired t-test. c Representative staining of POTEE with immunohistochemistry (IHC) analysis. d Overall survival rates of the CRC patients (n = 81) grouped by POTEE protein expression levels. e Overall survival of patients with CRC stratified by POTEE mRNA expression from GSE87211 dataset
