Exploring the underlying molecular mechanisms of HCC, such as those involving small ubiquitin-related modifier (SUMO) and its targets, is worthwhile. A total of 12 HCC tissue samples were collected for immunohistochemistry. The interaction between SUMO1 and OSR1 was confirmed by co-IP and immunofluorescence (IF). The expression (qPCR and western blot), cytological function (CCK-8, clone formation and transwell assays) of OSR1 was further investigated in HepG2 cells. The anti-tumor function of OSR1 was also verified in the nude mouse xenograft model. Western blot analysis revealed the underlying downstream signaling pathway of SUMO1-modified OSR1 in HCC. Up-regulated co-expression of SUMO1-OSR1 was observed in the HepG2 cells. Through the cytological experiments and a nude mouse xenograft model, we found that OSR1 is a tumor suppressor gene that inhibits the proliferation and invasion of the HepG2 cells in vitro. Intriguingly, SUMO1-OE antagonized OSR1-mediated β-catenin regulation: in nuclei, SUMO1-OE enhanced β-catenin expression, counteracting OSR1-OE-induced suppression, whereas in the cytoplasm, SUMO1-OE inhibited β-catenin accumulation and attenuated OSR1-OE-driven promotion. Hypoxia reversed these effects, suggesting an oxygen-sensitive interplay between SUMO1 and OSR1. In conclusion, OSR1 is a tumor suppressor in HCC via attenuation of the Wnt/β-catenin pathway.

Human NK cells are the primary innate immune cells that combat malignancies and exhibit significant diversity within the TME of gastrointestinal (GI) cancers. There is currently a growing interest in the advancement of chimeric antigen receptor (CAR)-engineered NK cells for GI cancer immunotherapy.
