Preclinical study reveals that EMC2 inhibits ferroptosis via TFRC degradation in nasopharyngeal carcinoma, highlighting a potential therapeutic target.

Key Points

To investigate the expression and clinical significance of EMC2 in nasopharyngeal carcinoma and identify the molecular mechanism by which it regulates ferroptosis.
Analyzed dysregulated proteins in nasopharyngeal carcinoma (NPC) tissues using quantitative proteomics and evaluated EMC2 expression and patient survival using tissue microarrays.
Assessed the effects of EMC2 knockdown and overexpression on cell viability, migration, invasion, cisplatin sensitivity, and xenograft tumor growth in nude mice.
Identified downstream regulatory targets of EMC2 using quantitative proteomics, protease inhibition assays, and ubiquitin detection.
EMC2 was significantly upregulated in NPC tissues and strongly correlated with aggressive tumor progression and poor patient survival.
EMC2 knockdown promoted ferroptosis, suppressed xenograft tumor growth, inhibited cancer cell invasion and migration, and sensitized NPC cells to cisplatin, while EMC2 overexpression had opposing effects.
EMC2 interacted directly with transferrin receptor (TFRC) to drive its ubiquitin-proteasomal degradation, thereby controlling ferroptosis sensitivity.
