LMP2A inhibits the expression of KLF5 through the mTORC1 pathway in EBV-associated gastric carcinoma
CONCLUSION: LMP2A downregulated KLF5 expression by inhibiting the mTORC1 pathway in EBV positive GC cells. KLF5 might play an oncogene-like role by promoting the migration of GC cells and inducing autophagy.PMID:35500764 | DOI:10.1016/j.virusres.2022.198792

Rapamycin enhances lytic replication of Epstein-Barr virus in gastric carcinoma cells by increasing the transcriptional activities of immediate-early lytic promoters.
In this study, we assessed the effects of rapamycin on EBV reactivation in gastric carcinoma cells. We found that rapamycin upregulated expression of EBV lytic proteins and increased the viral proliferation triggered by the EBV lytic inducer sodium butyrate. Reverse transcription-qPCR, luciferase activity assays, chromatin immunoprecipitation and western blotting were employed to explore the mechanism by which rapamycin promotes EBV reactivation. Our results showed that rapamycin treatment resulted in increased mRNA levels of EBV immediate-early genes. Rapamycin also enhanced the transcriptional activities of the EBV immed...

EBNA1 Binding and epigenetic regulation of gastrokine tumor suppressor genes in gastric carcinoma cells
Conclusions: These findings demonstrate that EBNA1 binds to the divergent promoter of the GKN1 and GKN2 genes in GC cells, and suggest that EBNA1 contributes to the complex transcriptional and epigenetic deregulation of the GKN1 and GKN2 tumor suppressor genes in EBV positive GC.
