microRNA‐1321 and microRNA‐7515 contribute to the progression of non‐small cell lung cancer by targeting CDC20
Abstract Cell division cycle 20 (CDC20) and microRNAs (miRNAs) are differentially expressed in non‐small cell lung cancer (NSCLC). The current study aimed to investigate the role of miR‐1321 and miR‐7515 regulation in CDC20 during NSCLC development. CDC20 expression in paracancerous and tumor tissue...

| description | Abstract Cell division cycle 20 (CDC20) and microRNAs (miRNAs) are differentially expressed in non‐small cell lung cancer (NSCLC). The current study aimed to investigate the role of miR‐1321 and miR‐7515 regulation in CDC20 during NSCLC development. CDC20 expression in paracancerous and tumor tissues was assessed using quantitative reverse transcription‐polymerase chain reaction (qRT‐PCR). The relationship between CDC20 expression and prognosis of patients was analyzed using the TCGA database. The expression profile of CDC20 in healthy lung cells and NSCLC cells was detected using qRT‐PCR and western blotting. After the knockdown of CDC20 in NSCLC cells, the cell proliferation, apoptosis, migration, invasion, and cell cycle changes were investigated by CCK8, EdU, flow cytometry, wound healing, and Transwell assays. The miRNAs targeting CDC20 were predicted using two bioinformatics websites and validated using dual‐luciferase assays. CDC20 was enhanced in NSCLC tissues and cells, thus predicting the poor prognosis in NSCLC patients. After CDC20 inhibition, the malignant phenotype of NSCLC cells was reverted. miR‐1321 and miR‐7515 targeted CDC20 and exhibited the same anti‐tumor effects as CDC20 silencing. Functional rescue experiments showed that CDC20 overexpression averted the anti‐tumor effects of miR‐1321 and miR‐7515 on NSCLC cells. miR‐1321 and miR‐7515 inhibited NSCLC development by targeting CDC20. Thus, the current study has implications in NSCLC treatment and provides novel insights into NSCLC management. |
