However, its roles and underlying mechanisms in lung adenocarcinoma (LUAD), one of the most aggressive cancers, remain elusive.  \nMethods Our study utilized in vitro cell phenotype experiments to assess CCT6A’s impact on the proliferation and invasion capabilities of LUAD cell lines. To delve into CCT6A’s intrinsic mechanisms affecting glycolysis and proliferation in lung adenocarcinoma, we employed transcriptomic sequencing and liquid chromatography-mass spectrometry analysis. Co-immunoprecipitation (Co-IP) and chromatin immunoprecipitation (CHIP) assays were also conducted to substantiate the mechanism.  \nResults CCT6A was found to be significantly overexpressed in LUAD and associated with a poorer prognosis. The silencing of CCT6A inhibited the proliferation and migration of LUAD cells and elevated apoptosis rates. Mechanistically, CCT6A interacted with STAT1 protein, forming a complex that enhances the stability of STAT1 by protecting it from ubiquitin-mediated degradation. This, in turn, facilitated the transcription of hexokinase 2 (HK2), a critical enzyme in aerobic glycolysis, thereby stimulating LUAD’s aerobic glycolysis and progression.  \nConclusion Our findings reveal that the CCT6A/STAT1/HK2 axis orchestrated a reprogramming of glucose metabolism and thus promoted LUAD progression. These insights position CCT6A as a promising candidate for therapeutic intervention in LUAD treatment.  \nKeywords CCT6A, Lung adenocarcinoma, Aerobic glycolysis, HK2, STAT1  \n*Correspondence:  \nKai-Hua Lu  \n[lukaihua@njmu.edu.cn](lukaihua@njmu.edu.cn)  \n1Department of Oncology, The First Affiliated Hospital of Nanjing Medical University, Nanjing, China  \n2Department of Pathology, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China  \nIntroduction  \nLung cancer stands as the second most common cancer worldwide and the foremost cause of cancer mortality [1]. Approximately 85% of diagnosed lung cancers are non-small cell lung cancers, and lung adenocarcinoma (LUAD) is the most common subtype of them [2]. Due to its high malignancy and the limited effectiveness of chemotherapy, patients with LUAD faced grim survival outcomes. The advent of targeted therapies has markedly prolonged the survival of patients with mutations in key driver genes such as EGFR, ALK, MET, ROS1, RET, and HER2 [3]. Nevertheless, a significant fraction of LUAD patients do not possess these mutations, highlighting the  \n© The Author(s) 2024.
