MAD2L1 and neoplasm: In our study, we found that STEAP3-AS1 and MAD2L1 were up-regulated in GBC tumor tissues, while as hsa-miR-192-5p was down-regulated, suggesting lncRNA STEAP3-AS1, might as a sponge of exosome-derived hsa-miR-192-5p, modulates cell cycle progression via affecting MAD2L1 expression in GBC tumorigenesis.
