ABSTRACT
BACKGROUND:
Long non-coding RNA (lncRNA) has gradually received widespread attention due to its role in regulating tumor progression. However, in renal cell cancer (RCC), the exact function of lncRNA LINC00671 remains uncertain.METHODS:
Quantitative real-time polymerase chain reaction (qRT-PCR) was utilized for detecting LINC00671 and miR-221-5p expressions in RCC tissues and cell lines. Western blotting technique was utilized for detecting the expressions of epithelial-mesenchymal transition (EMT)-associated proteins (E-cadherin and N-cadherin) and suppressor of cytokine signaling 1 (SOCS1). The correlation between clinicopathological features and LINC00671 expression was also evaluated. RCC cell multiplication, migration and invasion were measured by CCK-8, EdU and Transwell assays, respectively. The targeted relationships between LINC00671 as well as the SOCS1 3'UTR and miR-221-5p were verified by RNA immunoprecipitation (RIP) and luciferase reporter gene assay.RESULTS:
LINC00671 expression in RCC tissues and cells was significantly reduced. Patients with low LINC00671 expression had relatively shorter disease-free survival and overall survival. Moreover, LINC00671 expression was linked to lymph node metastasis, tumor stage, and tumor size. In Caki-1 and 769-P cell lines, LINC00671 overexpression restrained the multiplication, migration, invasion, as well as the EMT process of RCC cells in vitro. In terms of mechanism, miR-221-5p was identified as a target of LINC00671, and LINC00671 could up-regulate SOCS1 by repressing miR-221-5p.CONCLUSION:
LINC00671 regulates the miR-221-5p/SOCS1 axis as a tumor suppressor in RCC.
