Description

Lihuang Guo and co-authors found a kinase that helps breast cancer cells travel in clumps, in a 2025 study. Tumor cells shed into the blood spread cancer far better as clusters than alone, yet what glues them together was unclear. Mining gene data from single cells and clusters pointed to the kinase PAK2, already tied to advanced tumors. Clustered cells showed stronger cell-cell adhesion programs.

Lab and mouse work confirmed the lead: PAK2 tags the adhesion protein E-cadherin with a phosphate, tightening the bonds between cells. Blocking the kinase family with a drug in mice tested the treatment angle. The chain names both a driver of spread and a possible point of attack.
