ABSTRACT = {Ovarian cancer (OC) is a major cause of cancer-related deaths among gynaecological malignancies. Emerging studies
suggest that the long non-coding RNA (lncRNA) may be the potential biomarker for the diagnosis and prognosis of the cancer.
The current study was carried out to investigate the role of lncRNA CCHE1 silencing in OC cell invasion and migration.
Expression of lncRNA CCHE1 in normal ovarian cell Hose and OC cell lines HO 8910, A2780 and SKOV3 was detected.
LncRNA were transfected with siRNA, and then the proliferation of cells was detected by using MTT assay. Cell invasion
and migration was measured by using Transwell assay and scratch test, respectively. The protein levels of E-cadherin,
N-cadherin, ERK, p38-MAPK and the phosphorylation of ERK and p38-MAPK in cells after siRNA transfection were
detected by using Western blot analysis. Consequently, lncRNA CCHE1 expression was highly expressed in OC cell lines,
especially in SKOV3 cells. siRNA1, siRNA2 and siRNA3 all decreased. lncRNA CCHE1 expression in SKOV3 cells and
siRNA2 showed the best silencing efficacy. Silencing of lncRNA CCHE1 decreased proliferation, invasion and migration,
and reduced the protein levels of N-cadherin, ERK, p38-MAPK and the phosphorylation of ERK and p38-MAPK, while
reducing the protein level of E-cadherin in SKOV3 cells. Collectively, our study proved that the silencing of lncRNA
CCHE1 could inhibit SKOV3 cell invasion and migration via inactivating the p38-MAPK signaling pathway.},
