BACKGROUND/AIM: Gallbladder cancer (GBC) is a refractory cancer with poor prognosis. Recently, therapy targeting the tumor microenvironment (TME) has gained attention. Cancer hypoxia is a significant factor in the tumor microenvironment (TME). Our research has shown that hypoxia activates several molecules and signaling pathways that contribute to the development of various types of cancer. Our analysis indicated that C4orf47 expression was up-regulated in a hypoxic environment and had a role in the dormancy of pancreatic cancer. There are no other reports on the biological significance of C4orf47 in cancer and its mechanism is still unknown. This study analyzed how C4orf47 affects refractory GBC to develop a new effective therapy for GBC. MATERIALS AND METHODS: Two human gallbladder carcinomas were used to examine how C4orf47 affects proliferation, migration, and invasion. C4orf47 was silenced using C4orf47 siRNA. RESULTS: C4orf47 was over-expressed in gallbladder carcinomas under hypoxic conditions. C4orf47 inhibition increased the anchor-dependent proliferation and decreased the anchor-independent colony formation of GBC cells. C4orf47 inhibition reduced epithelial-mesenchymal transition and suppressed migration and invasiveness of GBC cells. C4orf47 inhibition decreased CD44, Fbxw-7, and p27 expression and increased C-myc expression. CONCLUSION: C4orf47 enhanced invasiveness and CD44 expression, and reduced anchor-independent colony formation, suggesting that C4orf47 is involved in plasticity and the acquisition of the stem-like phenotype of GBC. This information is useful for the development of new therapeutic strategies for GBC.
