Methods: Using public databases, the study assessed PHF5A expression and associations with prognosis, TMB, MSI, functional status, and tumor immunity, then validated findings in hepatocellular carcinoma with bioinformatics, qRT-PCR, and IHC. Results: PHF5A differed between tumor and normal tissues and correlated with prognosis, immune infiltration, checkpoint-related dysfunction, and pathway activity; HCC validation supported links to immune evasion, angiogenesis, and differential therapy response.

PHD-finger domain protein 5 A (PHF5A) has been reported to participate in various cancers; however, there has been no pan-cancer analysis of PHF5A. This study aims to present a novel prognostic biomarker and therapeutic target for cancer treatment.  \nMethods This study explored PHF5A expression and its impact on prognosis, tumor mutation burden (TMB), microsatellite instability (MSI), functional status and tumor immunity across cancers using various public databases, and validated PHF5A expression and its correlation with survival, immune evasion, angiogenesis, and treatment response in hepatocellular carcinoma (HCC) using bioinformatics tools, qRT-PCR and immunohistochemistry (IHC) .  \nResults PHF5A was differentially expressed between tumor and corresponding normal tissues and was correlated with prognosis in diverse cancers. Its expression was also associated with TMB, MSI, functional status, tumor microenvironment, immune infiltration, immune checkpoint genes and tumor immune dysfunction and exclusion (TIDE) score in diverse malignancies. In HCC, PHF5A was confirmed to be upregulated by qRT-PCR and IHC, and elevated PHF5A expression may promote immune evasion and angiogenesis in HCC. Additionally, multiple canonical pathways were revealed to be involved in the biological activity of PHF5A in HCC. Moreover, immunotherapy and transcatheter arterial chemoembolization (TACE) worked better in the low PHF5A expression group, while sorafenib, chemotherapy and AKT inhibitor were more effective in the high expression group.  \nConclusions This study provides a comprehensive understanding of the biological function of PHF5A in the carcinogenesis and progression of various cancers. PHF5A could serve as a tumor biomarker related to prognosis across cancers, especially HCC, and shed new light on the development of novel therapeutic targets.  \nKeywords Angiogenesis, Hepatocellular carcinoma, Pan-cancer, Prognosis, Treatment response, Tumor immunity  \n†Qianqian Cheng and Wenbin Ji contributed equally to this study and should be considered as co-first authors.  \n*Correspondence: Yan Yang [qiannianhupo@163.com](qiannianhupo@163.com)  \nFull list of author information is available at the end of the article  \n© The Author(s) 2024.
