WNT7A, a member of the Wnt family, remains poorly understood in terms of its role and the underlying molecular mechanisms it entails in head and necksquamous cell carcinoma (HNSCC) . According to the Cancer Genome Atlas (TCGA), transcriptome sequencing data of HNSCC, the expression level of WNT7A in tumors was found to be higher than in adjacent normal tissues, which was validated using Real-time RT-PCR and immunohistochemistry. Unexpectedly, overexpression of WNT7A did not activate the canonical Wnt-β-catenin pathway in HNSCC. Instead, our findings suggested that WNT7A potentially activated the FZD7/JAK1/STAT3 signaling pathway, leading to enhanced cell proliferation, self-renewal, and resistance to apoptosis. Furthermore, in a patient-derived xenograft (PDX) tumor model, high expression of WNT7A and phosphorylated STAT3 was observed, which positively correlated with tumor progression.

It is estimated that as many as 380 000 new cases of HNSCC worldwide in 2020, with a trend towards earlier age of onset, particularly in high-incidence areas such as Asia and Africa.1 HNSCC usually exhibits an invasive growth pattern, frequently leading to regional lymph node or hematogenous metastases. Despite recent advances in treatment technologies, the unclear etiology and pathogenesis of HNSCC often result in limited therapeutic options and suboptimal outcomes, particularly in cases with local or distant metastases.2  \nThe Wnt signaling pathway is a conserved signal transduction pathway in multicellular eukaryotes that exerts a wide range of biological effects. It plays a crucial role in various biological processes, such as cell growth, differentiation, proliferation, polarization, embryonic development, and stem cell self-renewal, and is involved in regulating most biological phenomena of life.3,4 Current research has established the crucial involvement of the Wnt signaling pathway in the onset and progression of numerous cancers.5,6 Aberrant activation of the Wnt signaling pathway affects the progress of several types of cells, enabling tumor cells to sustain and promote their stem cell phenotype, proliferation, and invasiveness. Among the identified cancers, over ten highincidence malignancies result from abnormal activation of the Wnt signaling pathway, including colorectal cancer,7 lung cancer,8 breast cancer,9 and childhood acute lymphoblastic leukemia.10 Several studies have confirmed that Wnt signaling pathway  \nimbalance can facilitate oral cancer development,11 and its abnormal activation can directly influence the prognosis of patients with oral cancer.2  \nThe Wnt signaling pathway is a complex network involving 19 WNT ligand proteins, 10 receptor proteins, and multiple common or accessory proteins. The activation of this pathway, whether through canonical or non-canonical signaling, is always initiated by WNT ligand proteins.
