“Background Gastric cancer (GC) is the second leading cause of global cancer mortality, accounting for 700,000 deaths annually [1,2]. More than 70% of countries worldwide have learn more a mortality-to-incidence ratio greater than 0.8, suggesting that prevention of late presentation and modified Selinexor in vivo treatment strategies are required to improve clinical outcomes [3]. In particular, distant metastases including peritoneal dissemination have been recognized as important prognostic determinants for GC patients [4,5]. Identifying genes relevant to the malignant behavior of GC could aid clinicians in tailoring treatments by identifying high-risk patients and proposing novel molecular targets [6]. Recently, technological advances such as microarrays and next-generation sequencing have allowed for the exhaustive

genomic characterization of malignancies, enhancing our understanding of cancer initiation and progression [7-9]. With these techniques, numerous genetic and epigenetic alterations relevant to gastric carcinogenesis and GC progression have been reported [10].

However, understanding the clinical significance of individual genes remains insufficient, despite the accumulating array data. Dihydropyrimidinase-like 3 (DPYSL3) is a cell-adhesion molecule [11,12] and actively expressed in normal tissues of cardiac myocytes, brain, pineal body, retina and smooth muscle, and moderately expressed in Protein kinase N1 various tissues including gastric tissues [13]. DPYSL3 has been reported to be involved in the metastatic process of tumor cells [14,15]. Gao et al. conducted expression and functional analyses of DPYSL3 in prostate cancer and found that DPYSL3 is a metastasis suppressor that is inversely associated with the expression of vascular endothelial growth factor (VEGF) [14]. In contrast, Kawahara et al. reported that DPYSL3 facilitates pancreatic cancer cell metastasis via a strong interaction with other cell adhesion factors, including ezrin (EZR), focal adhesion kinase (FAK) and c-SRC [15]. Thus, DPYSL3 has attracted attention as a metastatic modulator; however, the role of DPYSL3 expression in GC initiation and progression has not been investigated. Here, we focused on DPYSL3 as a potential facilitator of malignant behavior in GC. The aim of this study was to evaluate the clinical significance of DPYSL3 expression in GC.
