Abstract
Background: Gastric cancer (GC) seriously affects the life and health of patients, and the role of Elp3 in GC is still unclear; therefore, the aim of this study was to investigate the role and mechanism of Elp3 overexpression in GC.
Methods: Elp3-overexpressing HGC27 cells were constructed with an overexpression plasmid, and Elp3-overexpressing GC nude mice were prepared, which were intervened by histone acetylation inhibitor (SAHA) or JNK pathway inhibitor (SP600125). The protein interactions between Elp3 and JNK1 were verified by Co-immunoprecipitation (Co-IP) assay. Cell proliferation, migration, invasion, JNK/MAPK pathway, and histopathological changes were evaluated with CCK-8, clone formation assay, scratch assay, Transwell, qRT-PCR, western blot, and HE staining.
Results: Elp3 interacted with JNK1 protein, and Elp3 overexpression promoted GC proliferation, invasion, migration, elevated HAT activity, and activation of the JNK/MAPK pathway. A histone acetylation inhibitor attenuated the promotional effect of Elp3 overexpression on GC and activation of the JNK/MAPK pathway. Further, inhibition of the JNK/MAPK pathway also suppressed the promotion of GC by Elp3 overexpression.
Conclusion: Elp3 may be involved in GC progression by activating the JNK/MAPK pathway through histone acetylation.
期刊介绍:
HISTOLOGY AND HISTOPATHOLOGY is a peer-reviewed international journal, the purpose of which is to publish original and review articles in all fields of the microscopical morphology, cell biology and tissue engineering; high quality is the overall consideration. Its format is the standard international size of 21 x 27.7 cm. One volume is published every year (more than 1,300 pages, approximately 90 original works and 40 reviews). Each volume consists of 12 numbers published monthly online. The printed version of the journal includes 4 books every year; each of them compiles 3 numbers previously published online.
