However, the transcriptional regulators controlling this process in hepatocellular carcinoma (HCC) remain incompletely understood.  \nMethods A genome-wide CRISPR/Cas9 knockout screen identified ZNF217 as a key regulator of lipid metabolism in HCC. The regulatory effects of ZNF217 were analyzed using RNA sequencing, RT-qPCR, western blotting, and dual luciferase reporter assay. Intracellular lipid content was assessed using flow cytometry, oil red O staining, and triglyceride/cholesterol detection kits. Cell proliferation, migration, and invasion were assessed in vitro. In vivo tumor growth and metastasis were evaluated using nude mouse models. Clinical relevance was analyzed using immunohistochemical (IHC) staining, Kaplan– Meier survival analysis.  \nResults We identify the transcription factor ZNF217 as a key activator of de novo lipogenesis in HCC. ZNF217 binds to and transactivates the promoters of critical lipogenic enzymes, including fatty acid synthase (FASN) and acetyl-CoA carboxylase 1 (ACC1) . ZNF217-driven lipid synthesis, cell proliferation, migration, and invasion were dependent on FASN expression, as demonstrated by pharmacological inhibition and genetic knockdown. ZNF217 overexpression promoted HCC tumor growth and lung metastasis in a FASN-dependent manner in vivo. Clinically, ZNF217 was significantly upregulated in HCC tissues, positively correlated with FASN expression, and associated with poor patient survival.  \nConclusions Our findings establish ZNF217 as a novel transcriptional regulator of lipid metabolism in HCC, linking its oncogenic function to the activation ofthe lipogenic pathway, and propose the ZNF217-FASN axis as a candidate therapeutic target for HCC treatment.  \nKeywords De novo lipogenesis · Transcription factor · FASN · ZNF217 · Tumor growth · Tumor metastasis  \nYihui Fang, Ting Zhang and Tianxing Ye have contributed equally to this work and considered as co-first authors.  \n􀀍 Qinong Ye[yeqn88@163.com](yeqn88@163.com)  \n1 National Key Laboratory of Advanced Biotechnology, Academy of Military Medical Sciences, Beijing, China  \n2 Department of Gastroenterology, General Hospital of Northern Theater Command, Shenyang, China  \n3 Key Laboratory of Carcinogenesis and Translational Research (Ministry of Education/Beijing), Gastrointestinal Cancer Center, Peking University Cancer Hospital and Institute, Beijing, China  \n4 First Clinical College, Liaoning University of Traditional Chinese Medicine, Shenyang, China  \nIntroduction  \nMetabolic reprogramming is a defining hallmark of cancer, enabling malignant cells to sustain proliferation and survival in nutrient-fluctuating and often scarce microenvironments (Jiang et al. 2023; Lin et al. 2024a, 2024b; Perez et al. 2024) . Lipid metabolism, particularly the enhancement of lipid synthesis, plays a critical role in this process (Röhrig and Schulze 2016; Cheng et al. 2018; Li et al. 2021, 2024) . It provides not only essential membrane components and energy sources for tumor cells but also serves as signaling molecules that drive tumor progression.  \nTo meet heightened metabolic demands, cancer cells acquire lipids primarily through two pathways: de novo  \nsynthesis, involving the endogenous generation of fatty acids from acetyl-CoA, and exogenous uptake, where extracellular lipids are internalized via specific transportersand receptors (Butler et al. 2020) .
