MiR-618 suppresses the proliferation, invasion, and migration of non-small lung cancer via the JAK2/STAT3 axis

J Cardiothorac Surg. 2024 Dec 23;19(1):679. doi: 10.1186/s13019-024-03160-5.

Abstract

Objective: The regulatory role of the miR-618/JAK2/STAT3 axis in non-small cell lung cancer cells (NSCLC) was investigated with the objective of identifying a target for the precise treatment of patients with NSCLC.

Methods: Initially, differential gene expression was identified in the GEO database, followed by a comprehensive bioinformatics analysis. The tissue and cell levels of miR-618 were assessed using qRT-PCR, while the protein levels of JAK2 and STAT3 were determined through western blotting analysis. The association between miR-618 and JAK2 was scrutinized through bioinformatics analysis and dual-luciferase experiments. To evaluate cell proliferation, migration, and invasion, MTT, wound-healing, and Transwell assays were employed.

Results: The expression of miR-618 is decreased in NSCLC, and it targets the JAK2/STAT3 pathway to inhibit the proliferation, invasion, and migration of NSCLC.

Conclusion: Our study demonstrates that a novel miR-618/JAK2/STAT3 signaling axis is involved in suppressing malignancy in NSCLC and provides a promising target for NSCLC therapy.

Keywords: JAK2; Non-small cell lung cancer; STAT3; miR-618; miRNA.
