Expression level between tumor and normal tissues of hub genes in GEPIA. (A) Expression levels of ALB in pancreatic cancer. (B) Expression levels of APOL1 in pancreatic cancer. (C) Expression levels of COL6A3 in pancreatic cancer. (D) Expression levels of COL8A1 in pancreatic cancer. (E) Expression levels of COL11A1 in pancreatic cancer. (F) Expression levels of COL12A1 in pancreatic cancer. (G) Expression levels of FN1 in pancreatic cancer. (H) Expression levels of MMP14 in pancreatic cancer. (I) Expression levels of POSTN in pancreatic cancer. (J) Expression levels of THBS2 in pancreatic cancer. (K) Expression levels of VCAN in pancreatic cancer. “*”represents “P-value < 0.05”. P<0.05 was considered statistically significant. Y axis indicates relative expression value, log2(TPM+1). TPM=Transcript per million.
