To investigate the influence of CHEK1 gene expression on the prognosis of pancreatic cancer patients, we conducted an analysis of Kaplan-Meier survival curves for overall survival (OS) using the TISIDB (http://cis.hku.hk/TISIDB/index.php) and UALCAN (https://ualcan.path.uab.edu/) online platforms. Here, CHEK1 is linked to familial pancreatic carcinoma.
