  • Title: miR-9-5p Promotes Lung Adenocarcinoma Cell Proliferation, Migration and Invasion by Targeting ID4.
    Author: Zhu K, Lin J, Chen S, Xu Q.
    Journal: Technol Cancer Res Treat; 2021; 20():15330338211048592. PubMed ID: 34723712.
    Abstract:
    Objectives Evidence reveals that microRNAs (miRNAs) are abnormally expressed in lung adenocarcinoma (LUAD) tissue and are crucial in LUAD occurrence. Therefore, this study aims to find the miRNA which could regulate LUAD and to further explore its regulatory mechanism, thus providing a potential molecular target for LUAD. Methods miR-9-5p and ID4 expression in LUAD cells were measured by real-time quantitative PCR and western blot. Cell functional assays were conducted to detect the biological functions of LUAD cells. A dual-luciferase reporter assay was utilized to validate the binding relationship between miR-9-5p and ID4. Results miR-9-5p was highly expressed whereas ID4 was lowly expressed in LUAD. miR-9-5p facilitated LUAD cell progression by targeting ID4. Conclusion miR-9-5p promotes LUAD cell progression by modulating ID4 and may become a potential target for LUAD.
