Abstract

Human ovarian cancer stem cells (OCSCs) are one of the main factors affecting ovarian cancer cell metastasis, recurrence, prognosis and tolerance to chemotherapy drugs. However, the mechanisms of OCSC proliferation and invasion are not clear. Recent studies suggest that anisomycin can inhibit the proliferative and invasive ability of various tumor cells by increasing the production of the toxic amyloid β (Aβ1-42) peptides from the amyloid precursor protein (APP). We explored whether anisomycin could also suppress human OCSC proliferation and invasion. The CD44+/CD117+ OCSCs were enriched from human clinical ovarian tumor tissues. OCSCs treated with anisomycin showed reduced proliferation compared to controls. Moreover, anisomycin significantly suppressed the invasive capacity of OCSCs in vitro, as indicated by cell migration assays. The mRNA expression levels of long non-coding RNA (lncRNA) β-site APP cleaving enzyme 1 antisense strand (BACE1-AS) were significantly increased in anisomycin-treated OCSCs compared to controls. In addition, mRNA and protein levels of BACE1 and Aβ1-42 were increased in anisomycin-treated OCSCs compared to controls. We confirmed that anisomycin suppressed the growth of xenograft tumors formed by OCSC...Continue Reading
