Scientists discover how colon cancer cells change identity to spread

Researchers have pinpointed a molecular switch linked to colorectal cancer's ability to become lethal. When levels of the gene-regulating factor GATA6 drop, cancer cells lose their original identity and morph into flexible, fetal-like cells that can travel through the bloodstream and create new tumors in the liver. This transition seems to be more about changes in gene expression than new mutations, offering a new direction for understanding cancer progression and potential treatment strategies. This discovery could lead to better ways to predict and combat metastatic cancer.
