Using single-cell RNA sequencing from GEO, high-dimensional weighted gene co-expression network analysis identified gene modules linked to NSCLC clinical stages.

However, the intricacies of tumorigenesis and progression in this context remain incompletely understood.  \nMethods Utilizing single-cell RNA sequencing data retrieved from the GEO database, we performed highdimensional weighted gene co-expression network analysis to identify pivotal gene modules exhibiting the highest correlation with the clinical stages of NSCLC patients. Subsequently, we formulated a novel prognostic three-gene signature, subjecting it to thorough analysis using bulk RNA sequencing data obtained from theTCGA-LUAD dataset. Results A tumor-intrinsic prognostic signature, comprising SEC61G, NPTN, and ALDOA, emerged from our investigation. The risk score derived from this gene signature revealed significantly poorer overall survival among patients in the high-risk group. Patients in different risk groups exhibited distinct immune statuses, with those in the low-risk group likely to benefit more from immunotherapy. Furthermore, in vitro experiments demonstrated that SEC61G facilitates tumor proliferation and migration with the activation ofthe WNT/β-Catenin signaling pathway. Conclusion Our study unveiled a novel tumor-intrinsic gene signature, shedding light on improved prognostication for NSCLC and facilitating risk-stratified management.  \nKeywords HdWGCNA, Immune microenvironment, Immunotherapy, Non-small cell lung cancer, Prognostic signature  \n†Kunpeng Zhang, Wenqiang Xia andYi Li contributed equally to this work.  \n*Correspondence: Bowen Shi [bowen_shi@126.com](bowen_shi@126.com)[ ](bowen_shi@126.com)Weiwei Yang [CaylaYang@126.com](CaylaYang@126.com)  \n1Department of Thoracic Surgery, Shanghai Pulmonary Hospital, School of Medicine, Tongji University, Shanghai, China  \n2Shanghai Engineering Research Center of Lung Transplantation, Shanghai, China  \n3Department of Thoracic Surgery, Naval Medical Center, Shanghai, China 4Department of Orthopaedic, Tongji Hospital, School of Medicine, Tongji University, Shanghai, China  \nBackground  \nLung cancer is the second most prevalent malignancy globally, representing the primary cause of cancer-related mortality [1].
