Fig. 1: DPP3 was upregulated in CRC and knockdown of DPP3 cells models was constructed.

A, B The expression level of DPP3 was detected by IHC analysis in normal tissues and CRC tissues with different T stage. C Kaplan–Meier survival analysis was performed to establish the relationship between DPP3 expression and prognosis of CRC patients. The representative images were selected from at least three independent experiments. Data were shown as mean ± SD. *P < 0.05, **P < 0.01, ***P < 0.001.
