eIF4G2-Dependent Translation Restrains Pancreatic Cancer Progression.

Loss of eIF4G2 accelerates pancreatic cancer progression, metastasis, and basal-like tumor features, highlighting its role as a critical translational checkpoint.

• Why it matters: Understanding how translational control influences PDAC cell states is essential for developing strategies to limit malignant plasticity and improve patient outcomes, as current knowledge focuses mainly on transcriptional programs.
• What they did: A genome-wide CRISPR/Cas9 screen identified eIF4G2 as a key factor; its loss was studied through ribosome profiling, human PDAC cell experiments, and analysis of patient datasets, involving multiple functional assays.
• The result: Reduced eIF4G2 activity promotes tumor growth, metastasis, and basal-like features, while its expression suppresses clonogenicity, suggesting that targeting translational regulation could hinder PDAC progression.
