Abstract
AbstractUncontrolled growth, distant metastasis and chemoresistance are critical characteristics of pancreatic ductal adenocarcinoma (PDAC), and they result in high mortality; however, the mechanisms triggering these effects have not been fully investigated. In this study, we analysed a dataset in the Cancer Genome Atlas (TCGA) and identified PCDH1, a rarely studied transmembrane protein, as a novel prognostic marker in PDAC patients. We demonstrated that PCDH1 expression was upregulated in PDAC tissues, and its expression levels were associated with the depth of tumour invasion and lymph node metastasis. Patients with high PCDH1 levels showed poor overall survival (OS). We also investigated the biological significance of PCDH1 in PDAC cell growth, metastasis, and side population (SP) phenotype acquisition and explored the internal molecular mechanisms of PCDH1 action. Our results demonstrated that PCDH1 enhanced p65 nuclear localization by interacting with KPNB1, a well-characterized nuclear transporter, thereby activating the NF-κB signalling pathway and increasing its functional effects during PDAC progression. Hence, our results indicate that PCDH1 can be used as a negative prognostic marker and may be a potential therapeutic target for PDAC patients.
