Background
Head and neck squamous cell carcinoma (HNSCC) remains a lethal malignancy with its pathogenic mechanisms incompletely unraveled. This study interrogates the role of the HDAC2-GPD1 axis in driving HNSCC progression.
Methods
HDAC2 and GPD1 expression was analyzed in HNSCC tissues (IHC) and cell lines (RT-qPCR). TCGA-HNSCC dataset (520 tumors, 44 normal controls) was used for bioinformatics analysis of gene expression, correlation, and prognostic value. Stable HNSCC cell lines with HDAC2/GPD1 overexpression or knockout were established via lentiviral infection. CCK-8, Transwell, wound healing, and flow cytometry were performed to assess cell proliferation, invasion, migration and apoptosis in vitro. ChIP assays were conducted to verify the binding of HDAC2 to the GPD1 promoter and the H3K9ac modification of GPD1. Nude mice were implanted with modified FaDu cells to assess tumor growth via tumor measurements and HE analyses.
