Abstract
Purpose: Studies have determined that UNBS5162, recognized as a new naphthalimide, holds inhibitory effects in prostate and breast tumors; however, its functional implication on gastric carcinoma is currently undetermined. Based on this, this study designed to assess the functional role of it on human gastric carcinoma and underlying mechanism of action.
Methods: Cell counting kit-8 (CCK-8) assay, transwell assay, and flow cytometry were used to assess capabilities of SGC-7901 cell proliferation, invasion/migration, and apoptosis, respectively. Moreover, western blot was performed to determine the relative expression of protein related to autophagy and protein kinase B (AKT)/extracellular regulated protein kinases (ERK) signaling pathway.
Results: We found SGC-7901 cells proliferation, invasion, and migration were significantly inhibited after treatment of UNBS5162. Moreover, the expression levels of anti-apoptotic protein Bcl-2 decreased while the expression of pro-apoptotic protein active caspase 3 and Bax increased concurrently after UNBS5162 stimulation. Further, upregulated LC3 II/I and Beclin-1 and downregulated P62 were induced by UNBS5162 addition. Mechanically, the ratios of phosphorylated-(p-)AKT/AKT, p-mammalian target of rapamycin (mTOR)/mTOR, and p-ERK/ERK were hampered by UNBS5162 application.
Conclusion: UNBS5162 could restrain gastric carcinoma cell proliferation, invasion, and migration, which maybe induced by enhancement of apoptosis, autophagy manipulated through AKT/ERK signaling pathway.
