Molecular switch that activates cell growth signaling may offer more precise route for anticancer therapy

Cells carry their own growth switches.

When enough nutrients—amino acids in particular—are available, cells flip this switch on and begin to grow.

Researchers at KAIST and Yonsei University have uncovered the molecular mechanism by which amino acid signals activate this cellular growth switch.

The findings are expected to open a new avenue for anticancer therapies that target abnormal growth signaling in tumor cells. ...
