Abstract: OBJECTIVE: Breast cancer (BC) has a poor prognosis due to metastasis and recurrence. LINC01158 is aberrantly expressed in breast cancer. Therefore, we investigated the regulatory mechanism and prognostic value of LINC01158 in BC. METHODS: 121 patients with BC were enrolled. LINC01158 and miR-711 levels were analyzed by RT-qPCR. Independent predictors of poor BC prognosis were analyzed by multifactorial Cox regression. Kaplan-Meier curves were used to analyze the 5-year survival rate of BC patients. DLR assay verified the relationship between LINC01158 and miR-711 target binding. CCK-8 was used to detect the proliferative capacity of cells. Transwell was used to analyze cell migration and invasion ability. RESULTS: In BC tissues and cell lines, LINC01158 expression was reduced and miR-711 levels were elevated. Low expression of LINC01158 resulted in a shortened overall survival of BC patients. LINC01158 binds to the miR-711 target and negatively correlates with the level of miR-711. Overexpression of LINC01158 decreased miR-711 levels and reduced BC cell proliferation, migration and invasion. In addition, Cox regression results showed that LINC01158 was an independent prognostic factor for BC. CONCLUSION: LINC01158 may be a prognostic marker for BC. Increasing the expression level of LINC01158 could reduce the expression of miR-711, which could inhibit cell proliferation, migration and invasive behaviors, and has the potential to delay the progression of BC.
