Summary

Story summary

Researchers mapped mutations in the CTNNB1 gene, which encodes ?-catenin, to study cancer.
Researchers used a CRISPR-based approach to introduce 342 missense mutations in mouse stem cells and assess growth.
Mutations at the same position variably altered ?-catenin activity and tumor behavior.
Up to 30% of liver cancer patients harbor hotspot mutations, and mutation strength may affect immune responses and therapy outcomes, though validation across cell types is needed.
