OBJECTIVE: To reveal the role of LINC00958 in the progression of endometrial cancer (EC) and the underlying molecular mechanism.

PATIENTS AND METHODS: Quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) was conducted to detect relative level of LINC00958 in EC specimens and cell lines. Its prognostic potential in EC was analyzed by Kaplan-Meier method. After in vitro knockdown of LINC00958, cell proliferative, migratory and invasive abilities in KLE and Ishikawa cells were evaluated by Cell Counting Kit-8 (CCK-8), 5-Ethynyl-2’-deoxyuridine (EdU) and transwell assay. Dual-Luciferase reporter assay was carried out to identify the LINC00958/miR-3174/PHF6 axis, and their expression interaction was determined by Pearson correlation test. The role of miR-3174 in influencing LINC00958-induced phenotype changes of EC cells was determined through rescue experiments.

RESULTS: LINC00958 was abnormally upregulated in EC specimens and cell lines, which was unfavorable to the prognosis of EC. Knockdown of LINC00958 reduced proliferative, migratory and invasive rates in KLE and Ishikawa cells. MiR-3174 shared a binding site in the 3’-untranslated region (3’-UTR) to that of LINC00958, which was lowly expressed in EC specimens and negatively linked to LINC00958 level. Overexpression of miR-3174 partially abolished the role of LINC00958 in accelerating the malignant phenotypes of EC cells. PHF6 was the downstream target of miR-3174 and it was upregulated in EC specimens.

CONCLUSIONS: LINC00958 is upregulated in EC specimens, which is a prognostic factor of EC. It stimulates EC to proliferate, migrate and invade through the miR-3174/PHF6 axis.
