Cervical squamous cell carcinoma (CSCC) poses a significant health challenge, especially in developing countries. Identifying novel prognostic biomarkers and potential drug targets is crucial for improving CSCC management. We analyzed ADAMDEC1 expression patterns in CSCC using various bioinformatic datasets. Clinical samples from CSCC patients were evaluated for ADAMDEC1 and TYMP levels through Western blot and qRT-PCR. Multiple in vitro techniques, including flow cytometry, CCK-8, Transwell, Western blot, wound healing assays, and Co-IP, were employed to investigate the role and molecular pathways associated with ADAMDEC1. Our findings reveal that ADAMDEC1 is significantly overexpressed in CSCC tissues compared to adjacent healthy tissues. Functional assays demonstrated that ADAMDEC1 overexpression significantly enhances cell proliferation, migration, and invasion in vitro, while concurrently inhibiting apoptosis. Conversely, the knockdown of ADAMDEC1 reversed these effects, leading to reduced cell proliferation and increased apoptosis. Mechanistically, we identified a direct interaction between ADAMDEC1 and TYMP, which activates the JAK/STAT signaling pathway in CSCC cells. This activation was confirmed through Western blot analysis, indicating increased phosphorylation of JAK1 and STAT3 in response to ADAMDEC1 overexpression. ADAMDEC1 promotes CSCC progression by modulating the JAK/STAT pathway through regulation of TYMP. These findings suggest that ADAMDEC1 could serve as a molecular biomarker for early diagnosis and targeted therapy in CSCC.
