Abstract:
OBJECTIVE:Spinal cord injury (SCI) is a neurological disease with high incidence and disability. In this paper, we made a foundational study in long non-coding RNA paternally expressed gene 10 (lncRNA PEG10) at PC-12 cells. METHODS:We used CCK8, flow cytometry, migration and invasion assay to detect changes at the cellular level. PEG10, microRNA-34a-5p (miR-34a-5p) and TLX transfected by transfection assay and amplified by real-time quantitative PCR (qRT-PCR). TLX expression and proteins about apoptosis and pathways were investigated by Western blot. Additionally, the relationship between PEG10 and miR-34a-5p, miR-34a-5p and TLX were examined through luciferase assay. RESULTS:H2O2-injury model was established. Knockdown PEG10 deteriorated H2O2-injury. miR-34a-5p was confirmed as a target of PEG10 and miR-34a-5p inhibitor remitted PEG10-induced H2O2-injury. Moreover, TLX was confirmed as a target miR-34a-5p and TLX remitted H2O2-injury. At last, TLX worked in H2O2-injury via Smad and Wnt/β-catenin pathways. CONCLUSION:Knockdown PEG10 remitted H2O2-injury of PC-12 cells by targeting miR-34a-5p/TLX, and the behavior may be involved in Smad and Wnt/β-catenin pathways.
