Abstract
OBJECTIVE Isatin has gained attention in recent years owing to its anticancer properties and is thought to offer medical benefits. Isatin is an endogenous oxidized indole with various behavioral and metabolic properties and is commonly found in mammalian tissues and fluids. It has several plausible applications in biomedical research and has also been investigated as a potential anticancer agent. However, its effects on neuroblastoma (NB) cells are unclear. Here, we evaluate the effects of isatin on neuroblastoma cell metastasis and invasion and reveal the underlying mechanism. METHODS NB cell viability was evaluated with the cell counting kit (CCK)-8 assay. NB cell invasion and migration abilities were tested with transwell and wound healing experiments. The relative mRNA expression of associated molecules was detected with real-time polymerase chain reaction (RT-PCR) and quantitative PCR. The expression level of related proteins was detected with western blotting. RESULTS Isatin inhibited the proliferation, invasion, and migration of neuroblastoma cells in a dose-dependent manner. Isatin increased the expression level of H3K4m1 and phosphatase and tensin homolog (PTEN) and decreased the phosphorylation level of PTEN downstream proteins phosphoinositide 3-kinase, protein kinase B, mammalian target of rapamycin, focal adhesion kinase, and SHC. Together, these results support the potential anti-metastatic effects of isatin on NB cells.
