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.  \nResults 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.  \nConclusion 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.  \nKeywords Non-small cell lung cancer, miRNA, JAK2, miR-618, STAT3  \nIntroduction  \nLung carcinoma is one of the leading causes of global cancer mortality.Based on the information from GLOBOCAN 2018 data, approximately 2.09 million new cases and 1.76 million deaths are reported each year [1].

The 2015 data published by the National Cancer Center reveal that the 5-year prevalence rate of lung cancer in China during the period of 2006 to 2011 stood at 130.2 cases per 100,000 individuals.Of these cases, the prevalence rate for men was 84.6 (1/100 000), ranking second for malignant tumors, while the rate for women was 45.6 (1/100 000), ranking fourth for malignant tumors [2]. From a histopathological perspective, the two primary categories of lung carcinoma comprise small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC), with NSCLC accounting for approximately 85% of all cases based on histological analysis [3]. While the treatment methods for lung cancer have become more diverse, the survival rate of lung cancer patients is still only about 15% with late-stage disease  \n© The Author(s) 2024.
