Bioinformatics analyses combine multiple public resources, assessing differential expression, survival associations, immune correlations, and protein interaction networks. Results show TGFB1 overexpression in several tumors, links with advanced stage and worse outcomes in specific cancers, and low mutation frequency among surveyed cases.

Differential expression, survival, immune correlation, and protein interaction network analyses were performed.  \nResults: TGFB1 was overexpressed in several tumor types compared with that in normal tissues. High TGFB1 expression was associated with an advanced stage and poorer prognosis in certain cancers. TGFB1 mutations occurred in 1.3% of 10,967 cases surveyed. TGFB1 expression correlated with tumor-infiltrating immune cells and immunotherapy-related genes. Conclusions: This comprehensive multi-omics analysis revealed the complex expression and prognostic landscape of TGFB1 across cancers. TGFB1 is emerging as a potential immunotherapeutic target in certain contexts. Further research should elucidate its multifaceted tumorpromoting and tumor-suppressive mechanisms. Our pan-cancer analysis provides new insights into TGFB1 as a prognostic biomarker and immunotherapeutic target in human cancers, and our findings may guide future preclinical and clinical investigations of TGFB1-directed therapies.  \n1 Department of Hepatobiliary Surgery, Shulan (Hangzhou) Hospital Affiliated to Zhejiang Shuren University Shulan International Medical College, Hangzhou, China 2School of Medicine, Zhejiang Chinese Medical University, Hangzhou, China  \n3School of Medicine, Zhejiang Shuren University, Hangzhou, China  \nCorresponding author:  \nQiyong Li, \\#848 Dongxin Road, Hangzhou City, Zhejiang Province 310000, China.  \nEmail: [liqiyong@zju.edu.cn](liqiyong@zju.edu.cn)  \nCreative Commons Non Commercial CC BY-NC: This article is distributed under the terms of the Creative  \nCommons Attribution-NonCommercial 4.0 License ([https://creativecommons.org/licenses/by-nc/4.0/](https://creativecommons.org/licenses/by-nc/4.0/)) which permits non-commercial use, reproduction and distribution of the work without further permission provided the original work is attributed as specified on the SAGE and Open Access pages ([https://us.sagepub.com/en-us/nam/open-access-at-sage](https://us.sagepub.com/en-us/nam/open-access-at-sage)).  \nKeywords  \nTransforming growth factor beta 1, pan-cancer, gene mutation, prognosis, immunotherapeutic target, multi-omic analysis  \nDate received: 17 August 2023; accepted: 16 November 2023  \nIntroduction  \nBoth the incidence of cancer and cancer mortality are growing rapidly worldwide, and cancer is a leading cause of death in the 21st century and a major obstacle in improving life expectancy worldwide.1–3 In 2018, there were 18.1 million new cases and 9.6 million cancer deaths worldwide.
