Randomized trial investigates miRNA-32's effect on non-small cell lung cancer cell activity, suggesting its role as a biomarker.

This research examines how miRNA-32 influences cell growth and movement in non-small cell lung cancer by targeting MEF2D.
Quantitative real-time PCR assessed miRNA-32 levels in NSCLC tissues and cell lines.
Western blotting was used to analyze protein levels of MEF2D, E-cadherin, N-cadherin, and CyclinD1.
Cell proliferation and migration were evaluated with Cell Counting Kit-8 and Transwell assays, and a dual-luciferase reporter assay verified miRNA-32's regulation of MEF2D.
miRNA-32 was significantly downregulated in lung cancer tissues and cell lines, while MEF2D was upregulated.
High miRNA-32 expression correlated with poor clinical outcomes in NSCLC.
Overexpression of miRNA-32 inhibited lung cancer cell proliferation and migration, with MEF2D overexpression reversing these effects.
