MAGP1 maintains tumorigenicity and angiogenesis of laryngeal cancer by activating Wnt/β-catenin/MMP7 pathway

Microfibril-associated glycoprotein-1 (MAGP1), a crucial extracellular matrix protein, contributes to the initiation and progression of different cancers. However, MAGP1's role in laryngeal Cancer is not clear. The purpose of this study was to investigate the clinical significance and biological function of MAGP1 in laryngeal Cancer. MAGP1 was upregulated in public databases and laryngeal Cancer tissues, and high MAGP1 expression led to a poor prognosis and was identified as an independent prognostic marker. Knocking-down MAGP1 inhibited laryngeal Cancer cells growth and metastasis. According to GSEA, high MAGP1 expression revealed enrichment in Wnt/β-catenin signaling and knocking-down MAGP1 in laryngeal Cancer cells also caused degradation, de-activation, re-location, and loss of stability of β-catenin. Additionally, we observed MAGP1 in laryngeal Cancer cells inhibits angiogenesis in an MMP7-dependent way. In conclusion, our study suggests a clinical role of MAGP1 in laryngeal Cancer, signifying its potential as a therapeutic target in the future.
