Long non-coding RNAs (lncRNAs) highly upregulated in liver cancer (HULC) has been identified as an oncogene involved in many human cancers. Herein, we aimed to further explore the role and molecular mechanism of HULC in gastric cancer (GC) progression. The levels of HULC, miR-9-5p and myosin heavy chain 9 (MYH9) mRNA were detected by qRT-PCR. The targeted interaction between HULC and miR-9-5p was verified by dual-luciferase reporter and RNA pull-down assays. Cell proliferation assay, cell colony formation, flow cytometry and transwell assay were used to determine cell proliferation, colony formation, apoptosis and migration and invasion, respectively. Xenograft assay was used to observe the effect of HULC on GC growth in vivo. Our results revealed that HULC was upregulated and miR-9-5p was downregulated in GC, and both were associated with clinicopathologic features of GC patients. A positive correlation was found between HULC expression and epithelial-to-mesenchymal transition (EMT) of GC tissues. Moreover, HULC repressed miR-9-5p expression by binding to miR-9-5p. The regulatory effects of HULC knockdown on GC cell proliferation, migration, invasion, EMT and apoptosis were reversed by introduction of anti-miR-9-5p. HULC regulated MYH9 expression by acting as a molecular sponge of miR-9-5p in GC cells. HULC knockdown inhibited tumor growth in vivo. In conclusion, our data demonstrated that HULC knockdown repressed GC progression at least partly by regulating miR-9-5p/MYH9 axis. Copyright © 2019 The Authors. Published by Elsevier Masson SAS..
