Аннотация
BACKGROUND: Gallbladder carcinoma (GBC) is a common malignant tumor of the biliary system, but the current treatment of GBC is unsatisfactory. Therefore, new treatment targets and strategies are urgently needed.
METHODS: The expression of HASPIN in GBC was detected by immunohistochemical staining. HASPIN knockdown cell model was constructed by lentivirus infection, and the infection efficiency of lentivirus and knockdown efficiency of shHASPIN were verified by fluorescence immunoassay, qRT-PCR and Western blot. The effects of HASPIN knockdown on cell proliferation, clone-formation ability and apoptosis were determined by MTT, clone formation assay, flow cytometry and Human Apoptosis Antibody Array in vitro. Besides, the effect of HASPIN knockdown on the growth of GBC solid tumors was demonstrated in vivo.
RESULTS: The expression of HASPIN in GBC was up-regulated and positively correlated with the pathological grade of GBC. ShHASPIN significantly down-regulated the mRNA and protein levels of HASPIN, suggesting that HASPIN knockdown cell model was successfully constructed in vitro. After HASPIN knockdown, the proliferation and clone-formation ability of GBC cells were observably inhibited, the apoptotic levels were markedly increased, and the expression of Caspase 3, IGFBP-5, p21 and sTNF-R1 related to apoptotic pathway was up-regulated. Furthermore, HASPIN knockdown inhibited the growth of GBC in vivo.
CONCLUSION: HASPIN was up-regulated in GBC and played an important role in promoting the progress of GBC.
