Methods: Immunohistochemistry quantified SORT1 in tumor versus adjacent tissues. NSCLC cell lines were treated with miR-146a mimics or SORT1 siRNA, then assessed for viability, migration, invasion, and apoptosis; bioinformatics predicted miR-146a targets, verified by dual-luciferase assays. Results: SORT1 was elevated in NSCLC; its downregulation suppressed proliferation, migration, invasion, and promoted apoptosis.

sortilin-1  \nABSTRACT  \nBackground: Sortilin-1 (SORT1) has been implicated in the pathogenesis of various malignancies, but its role in non-small cell lung cancer (NSCLC) remains to be elucidated.  \nMethods: Immunohistochemistry was employed to assess the expression of SORT1 in cancerous tissues compared to adjacent non-cancerous tissues. NSCLC cell lines, including A549, H1299, and PC-9, underwent treatment with miR-146a mimics or SORT1 small interfering RNA (siRNA), followed by evaluations of cell viability, migration, invasion, and apoptosis using cell counting kit-8, transwell assays, and scratch wound assays. Additionally, bioinformatic methods were employed to predict miR- 146a target genes, which were subsequently validated through dual-luciferase reporter assays.  \nResults: SORT1 was significantly elevated in NSCLC tissues compared to adjacent non-cancerous counterparts. Downregulation of SORT1 inhibited proliferation, invasion, migration of tumor cell lines and promoted apoptosis. Moreover, SORT1 was a direct target of miR-146a. MiR-146a modulated tumor cell proliferation, migration, invasion, and apoptosis by suppressing SORT1 expression.  \nConclusion: These results suggest that miR-146a plays a critical role in the pathogenesis of NSCLC by targeting SORT1, highlighting its potential as a therapeutic target for NSCLC.  \n\n| Xi Lin and Zhi Yan contributed equally to this work. |\n| --- |\n| This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.\u003Cbr>© 2025 The Author(s) .
