When ZFP36L2 is lost, metastatic CRC cells shift away from the ISC-dedifferentiation program toward non-canonical fates, with markers such as CK5 and CHGB rising and LGR5 declining in patient metastases and organoid models.

A key stress-responsive mediator, ZFP36L2 links AP-1 driven injury programs to intestinal cell dedifferentiation back to LGR5+ intestinal stem cells, a process vital for regeneration and for canonical metastasis in colorectal cancer.

Overall, ZFP36L2 coordinates stress-induced dedifferentiation into an ISC state, promoting epithelial regeneration and enabling cancer stem cell–like transitions during metastasis; its absence biases cells toward non-canonical, potentially more invasive differentiation paths.

The study highlights the complex role of cancer cell-state transitions in metastasis and suggests that disrupting these transitions may have unexpected biological consequences compared with prior expectations.

Loss of ZFP36L2 impairs metastatic seeding but drives tumors to adopt alternative, more plastic differentiation programs linked to poorer clinical outcomes.

ZFP36L2 acts by coordinating degradation of stress-related mRNAs, connecting stress responses, RNA biology, and cellular plasticity to cancer progression.
