Matrix metalloproteinase 11 (MMP11) has been linked to tumor progression and immune microenvironment modulation. This study explored MMP11's role in regulating the PD-L1/c-Myc pathway in ESCA.<h4>Methods</h4>MMP11 expression was analyzed in ESCA tissues and cell lines using real-time PCR and western blot. Kaplan-Meier survival curves assessed the relationship between MMP11 expression and patient survival. Functional assays, including wound healing and flow cytometry, were conducted to examine ESCA cell migration and apoptosis.<h4>Results</h4>MMP11 silencing reduced PD-L1 expression and inhibited cell migration, while promoting apoptosis.
