Copper content increased in pancreatic cancer tissues. A, the copper content was determined by ICP‐MS assay in pancreatic cancer (P1‐P10 and six mixed samples) and adjacent non‐cancer (AC) tissue specimens. Data shown are mean ± SD, n = 6, **P < 0.01 (Student's t test). B, the correlation between copper content and the survival time was analyzed in eight patients. C, GEO data analysis of Slc31a1 expression in pancreatic cancer and normal tissues. D, The SLC31A1 protein expression was examined by immunohistochemical staining. E, the correlation of Slc31a1 mRNA levels and the survival time was analyzed in 87 patients using data from the OncoLnc database
