Therefore, we seek to examine P4HA2 expression and effect in HNSCC, along with the underlying mechanisms. This study utilized integrated bioinformatics analyses to evaluate the P4HA2 expression pattern, prognostic implication, and probable function in HNSCC. The study conducted various in vitro experiments, including colony formation, CCK-8, flow cytometry, wound healing, and transwell assays, on the human HNSCC cell line CAL-27 to examine the involvement of P4HA2 in HNSCC progression. Moreover, western blotting was used to investigate epithelial-mesenchymal transition (EMT) markers and PI3K/AKT pathway markers to elucidate the underlying mechanisms. P4HA2 expression was significantly enhanced in HNSCC, and its overexpression was correlated to tumor aggressiveness and a poor prognosis in patients. Based on in vitro experiments, the overexpressed P4HA2 enhanced cell proliferation, migration, invasion, as well as EMT while reducing apoptosis, whereas P4HA2 silencing exhibited the reverse effect. P4HA2 overexpression enhanced PI3K/ AKT phosphorylation in HNSCC cells. Moreover, LY294002 was observed to counteract the effects of upregulated P4HA2 on proliferation, migration, invasion, and EMT in HNSCC. Collectively, we indicated that P4HA2 promoted HNSCC progression and EMT via PI3K/AKT signaling pathway.  \nKeywords P4HA2 · Head and neck squamous cell carcinoma · EMT · PI3K/AKT pathway · Prognostic marker  \nYan-Ling Wu and Wan Liu have contributed equally to this work.  \n* Jing Jin [jinjing@cicams.ac.cn](jinjing@cicams.ac.cn)  \n[Yan-Ling Wu](Yan-Ling Wu)  \n[wuyl_1202@163.com](wuyl_1202@163.com)  \nWan Liu  \n[tyr1573@163.com](tyr1573@163.com)  \nTingting Zhao  \n[zttdistinctive06@163.com](zttdistinctive06@163.com)  \n1 Department of Radiation Oncology, National Cancer Center/National Clinical Research Center for Cancer/ Cancer Hospital and Shenzhen Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Shenzhen 518116, Guangdong, China  \n2 Department of Head and Neck Surgery, National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital & Shenzhen Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Shenzhen 518116, Guangdong, China  \nIntroduction  \nHead and neck cancers, which encompass various cancers such as nasopharyngeal cancer, oral cancer, laryngeal cancer, and hypopharyngeal cancer, can manifest with diverse primary sites and pathological subtypes. Squamous cell carcinoma is the most common type of head and neck cancer, accounting for over 90% of cases [1] . Head and necksquamous cell carcinoma (HNSCC) is considered a widely occurring malignancy on a global scale, with an excess of 800,000 incidences and over 350,000 mortalities annually [2] . HNSCC threats, to a great extent, not only human health but also their quality of life due to its elevated rates of primary-site recurrence and metastasis, as well as latestage diagnosis and poor prognosis [3] . Although surgical technology has improved dramatically, the use of radiation and chemotherapy has demonstrated enhanced management of local HNSCC control; these treatment options can lead to cosmetic deformity and functional impairment of vital functions [4] . The low overall 5-year survival rate that is shown in HNSCC patients can be attributed to the increased  \ntreatment failure and recurrence rates, besides the nodal metastasis.
