ALKBH5 in Cancer-Associated Fibroblasts Governs an Epitranscriptomic Axis That Drives Pancreatic Cancer Metastasis.
- Open access
ALKBH5-driven epitranscriptomic changes in cancer-associated fibroblasts promote pancreatic cancer metastasis independently of primary tumor growth.
- Why it matters: Understanding how CAFs influence tumor progression is crucial for developing targeted therapies, especially since their regulatory mechanisms are not fully elucidated and metastasis remains a major challenge.
- What they did: The study analyzed m6A modifications in CAFs, identifying ALKBH5 as a key regulator that enhances tumor cell migration and invasion through an m6A-dependent pathway involving HSF1 and LIF signaling, using genetic and co-implantation models.
- The result: Elevated ALKBH5-HSF1-LIF CAFs correlated with poor prognosis and metastasis in PDAC, revealing a stromal epitranscriptomic program that could serve as a therapeutic target to inhibit pancreatic cancer spread.
