N Body weight of mice was examined on day 3, 6, 9, 12, 15, and 18, after OVCAR-8 cell injection. ** p < 0.01 versus Control, ## p < 0.01 versus GPR137; error bar, SD. O KI-67 staining and RAB8A staining for tumor tissues derived from OVCAR-8 cells stably expressing GPR137 or in combination with hnRPD shRNA (shhnRPD) on day 18 post inoculation. In Control group, tumor tissues were derived from OVCAR-8 cells infected with control lentiviruses in combination with lentiviruses carrying a scrambled shRNA sequence. Bar, 20 μm. P Statistical analysis of KI-67 index (%) from (F). ** p < 0.01 versus shRNA-Con+Control, ## p < 0.01 versus shRNA-Con+GPR137; error bar, SD. Q IHC score for RAB8A staining in (O). ** p < 0.01 versus shRNA-Con+Control, ## p < 0.01 versus shRNA-Con+GPR137. R The mRNA levels of RAB8A in formed tumor tissues derived from OVCAR-8 cells stably expressing GPR137 or in combination with hnRPD shRNA (shhnRPD). ** p < 0.01 versus shRNA-Con+Control, ## p < 0.01 versus shRNA-Con+GPR137; error bar, SD. S The protein levels of RAB8A in formed tumor tissues derived from OVCAR-8 cells stably expressing GPR137 or in combination with hnRPD shRNA (shhnRPD). In Control group, tumor tissues were derived from OVCAR-8 cells infected with control lentiviruses in combination with lentiviruses carrying a scrambled shRNA sequence (labeled as GPR137, -; shhnRPD, -). T qRT-PCR analysis of co-precipitated RAB8A mRNA by hnRPD antibody in the RIP assay in tumor tissues. IgG was used as a negative control. ** p < 0.01 versus IgG; error bar, SD. N = 3. U RNA pull-down assay in tumor tissues with RAB8A RNA or control RNA fragments. Protein abundance was normalized to a Tubulin
