Unresolved DNA bridges in Caenorhabditis elegans lem-3/ANKLE1 mutants promote stable intercellular bridges that form binucleate syncytia between touch receptor neurons and sister cells.
- Why it matters: Failed cytokinesis can leave postmitotic cells with altered fate, but how unresolved chromatin bridges affect neuronal differentiation is unclear.
- What they did: The study used genetic analysis, fluorescence microscopy, and RNA visualization in Caenorhabditis elegans mutants lacking the midbody-tethered endonuclease LEM-3/ANKLE1 that resolves chromatin bridges.
- The result: The resulting cytoplasmic mixing occurs despite independent nuclear transcription, and in some cases it suppresses neuronal fates and prevents apoptotic fates, implying LEM-3 safeguards differentiation by blocking syncytium formation.
