SOX4-ZIP14-zinc metabolism mediates oncogenesis and suppresses T cell immunity in nasopharyngeal carcinoma.

ABSTRACT: Subtle variations of micronutrients in the tumor microenvironment often coincide with tumor progression and immune disorders. Nevertheless, the underlying mechanisms of how micronutrients, such as metal ions, influence tumor-intrinsic properties and tumor-immune crosstalk remain inadequately characterized. Here, our integrative analysis of multi-center single-cell, spatial transcriptome sequencing, and bulk RNA sequencing (RNA-seq) cohorts reveals that nasopharyngeal carcinoma (NPC)-specific SRY-box transcription factor 4 (SOX4) governs microenvironmental and cellular zinc metabolism through its downstream target, SLC39A14 (ZIP14), a membrane zinc uptake transporter. Mechanistically, NPC cells enhance zinc uptake and activate Wnt/β-catenin signaling to initiate tumor growth, creating a zin
