and AstraZeneca Plc. progression were also examined following small interfering RNA-mediated SMYD2 silencing or treatment with a selective SMYD2 inhibitor. SMYD2 was significantly upregulated in clinical OCCC specimens, compared with normal ovarian tissue. In addition, SMYD2 knockdown decreased cell viability as decided via a Cell Counting Kit-8 assay. Moreover, the proportion of cells in the sub-G1 phase increased following SMYD2 knockdown, suggesting increased apoptosis. Treatment with the SMYD2 inhibitor LLY-507 suppressed OCCC cell viability. These results suggested that SMYD2 could FRP promote OCCC viability, and that SMYD2 inhibition induced apoptosis in these cells. Thus, SMYD2 inhibitors may represent a encouraging molecular targeted approach for OCCC treatment. validation is required to ascertain whether SMYD2 might serve as a potential therapeutic target in OCCC. Moreover, the mechanism of action underlying the effect of SMYD2 on cell proliferation and apoptosis, including the potential role of p53 methylation, has not been addressed. Lastly, endometriosis is reportedly Androsterone a precursor of OCCC (34), and therefore analysis of SMYD2 expression in OCCC should be compared with normal ovarian tissues as well as with tissues of endometriosis in the future. Nevertheless, the present findings suggest that SMYD2 increases the proliferation of OCCC cells em in vitro /em , suggesting a potential therapeutic avenue for SMYD2 inhibition in the treatment of OCCC.
