Gallbladder carcinoma (GBC) is the most prevalent cancer of the bile tract, with unexpected GBC accounting for almost half of all GBC cases in some tertiary medical centers. Although the involvement of microcystin-leucine-arginine (MC-LR) in the development of intrahepatic cholangiocarcinoma has been established, there is a paucity of data regarding its association with GBC. The present study aims to investigate whether MC-LR level in the gallbladder of patients is associated with GBC development and, if so, to characterize the underlying mechanism in GBC cells. Our clinical data revealed that MC-LR level was significantly increased in GBC patients compared to patients with gallbladder stones only (P = 0.009). Moreover, our findings demonstrated that MC-LR could promote the proliferation and metastasis of human GBC cell lines. Furthermore, ELAC2 was identified as a critical mRNA involved in GBC progression through RNA sequencing. Collectively, our study suggests that MC-LR might be involved in the development of GBC by modulating the expression of ELAC2. • Higher content level of MC-LR increased the incidence of gallbladder carcinoma. • MC-LR induce the proliferation and metastasis of gallbladder carcinoma cells. • ELAC2 was involved in the tumor progression induced by MC-LR.
