Objective: To analyze the effects of Grifola frondose polysaccharide (GFP) on proliferation, migration and invasion of gallbladder carcinoma cells and its mechanism. Methods: Logarithmic phase GBC-SD cells randomized: Control group, GFP group (0.5, 1,2 µg/mL GFP), shNC group, shHULC group, miR-NC group, miR-186-5p mimics group, GFP+pcDNA group, GFP+pcDNA-HULC group. Cell inhibition rate was detected by CCK-8 method. The migration and invasion of GBC-SD cells were detected by Transwell cell assay. The protein levels of Cyclin D1, P21, MMP-2 and MM-9 were detected by Western Blot. LncRNA HULC and miR-186-5p levels were detected by qRT-PCR. Starbase online software predicted the binding sites of HULC and miR-186-5p, dual luciferase reporting assay was used to detect the targeting relationship between LncRNA HULC and miR-186-5p. The effect of GFP on the endogenetic growth of GBC-SD cells was detected by tumor transplantation in nude mice. Results: 0.25~8 µg/mL GFP had definite inhibitory effect on GBC-SD cells of gallbladder carcinoma. Compared with the control group, 0.5, 1 and 2 µg/mL of GFP (extremely) significant (P0.05). Compared with shNC group, the relative expression level of HULC in shHULC group was extremely significant (P
