Abstract
Exploring the role of novel cancer gene BZW1 in lung adenocarcinoma (LUAD) and unveiling associated signalling pathways. Firstly, we conducted a pan-cancer analysis of BZW1 using multiple databases. Subsequently, leveraging single-cell data from LUAD, we successfully uncovered potential oncological processes associated with BZW1 and further validated them through experimentation. Simultaneously, we continued to investigate the potential molecular mechanisms underlying the oncological processes mediated by BZW1. Additionally, we employed various machine learning algorithms to construct prognostic models concerning BZW1 and the epithelial-mesenchymal transition (EMT) process. Our research firstly demonstrated the elevated expression of BZW1 in various cancer cells. Leveraging single-cell data from LUAD, we identified that BZW1 regulates the occurrence of EMT in LUAD, a phenomenon validated across multiple LUAD cell lines. Moreover, we further discovered that BZW1 regulates LUAD's EMT process through the Wnt/β-catenin signalling pathway. Lastly, we successfully constructed prognostic models using BZW1-related genes and EMT genes.
