MRPS7 and nasopharyngeal carcinoma: Mechanistically, integrated single-cell RNA-seq (scRNA-seq) analysis, mass spectrometry, and functional studies revealed that MRPS7 and MRPS23 stabilized β-catenin by inhibiting its ubiquitination, thereby promoting β-catenin-mediated cancer stemness and epithelial-mesenchymal transition (EMT) to establish cisplatin resistance in NPC.
