Additionally, we performed immunofluorescence staining for CDH17 in the subcutaneous tumors of mice bearing ASPC1 cells (a human pancreatic cancer cell line), and the results showed substantial CDH17 protein expression around the tumor cells (Fig. 1L and M) We also analyzed the expression level of CDH17 between normal tissues (N) and tumor samples (T) across multiple GI cancer types by GEPIA2 website.35 This evidence concerns the gene CDH17 and familial pancreatic carcinoma.
