ALKBH5 in Cancer-Associated Fibroblasts Governs an Epitranscriptomic Axis That Drives Pancreatic Cancer Metastasis.

ALKBH5 in cancer-associated fibroblasts promotes pancreatic cancer metastasis through an epitranscriptomic signaling axis.

• Why it matters: Understanding how CAFs influence PDAC progression is crucial, as they are key determinants of tumor behavior and metastasis, yet their regulatory mechanisms remain incompletely known.
• What they did: The study used models of PDAC to show that ALKBH5 regulates m6A remodeling in CAFs, enhancing tumor cell migration, invasion, and epithelial-mesenchymal transition via an HSF1-LIF signaling pathway.
• The result: Elevated ALKBH5⁺HSF1⁺ CAFs predict poor prognosis and are enriched in metastatic PDAC, revealing stromal m6A regulation as a potential target for therapy.
