Results show HNRNPC preserves TFAP2A mRNA stability, activates the TFAP2A/CTNNB1 axis, promotes EMT, and enhances malignant growth and distant metastasis.

This study aimed to discuss molecular mechanism of HNRNPC in NSCLC.  \nMethods HNRNPC expression and clinically relevant data in pan-cancer and LUAD were extracted through these websites, including UALCAN, TIMER2 and GEPIA. The target gene of HNRNPC were identified through RIP-seq, meRIPqPCR and mRNA stability test. The differential expression of target gene in NSCLC was explored by immunohistochemistry. Lentivirus was selected to knock down HNRNPC and plasmid was selected to overexpress downstream target genes. The transfection efficiency was verified by RT-qPCR and Western Blot. In vitro colony formation assay, CCK-8, wound healing, transwell assays were performed to determine the biological functions of HNRNPC and target gene in lung adenocarcinoma cells.  \nResults HNRNPC can promotes the expression ofTFAP2A by recognizing the m6A modification ofTFAP2A mRNA and maintaining its stability, activates the TFAP2A/CTNNB1 axis, enhances EMT, and ultimately promotes the malignant process of NSCLC and promote distant metastasis of NSCLC.  \nConclusions These results supported that HNRNPC regulate TFAP2A to promote the malignant progression and EMT of NSCLC. These findings connect m6A modification with EMT, providing a new perspective on the regulation of m6A modification in tumors.  \nKeywords NSCLC, HNRNPC, TFAP2A, N6-methylation, Epithelial to mesenchymal transition  \n†Minghua Liao and Chunyu Li equally contributed to the manuscript.  \n*Correspondence: Xianming Zhang  \n[zxm13078524367@163.com](zxm13078524367@163.com); [zhangxianming@gmc.edu.cn](zhangxianming@gmc.edu.cn)  \n1 Department of Respiratory and Critical Medicine, The Affiliated Hospital of Guizhou Medical University, 28 Guiyi Street, Guiyang, Guizhou 550004, China  \n2 School of Clinical Medicine, Guizhou Medical University, Guiyang, Guizhou 550004, China  \n3 Department of Internal Medicine, Guiyang First People’s Hospital, Guiyang, Guizhou 550004, China  \nIntroduction  \nLung cancer is the leading cause of cancer-related death in the world [1]. The main pathological classifications are small cell lung cancer and non-small cell lung cancer (NSCLC), with NSCLC accounting for about 80–85% of cases [2]. NSCLC consists mainly of adenocarcinoma and squamous cell carcinoma, which account for more than 70% of the total risk of NSCLC [3]. And for patients with NSCLC with metastasis, treatment outcomes and prognosis remain poor [4]. Hence, further elucidation of NSCLC metastasis mechanisms and identification of  \n© The Author(s) 2025.
