Protein appears to prevent tumor cells from spreading via blood vessels
Johns Hopkins researchers describe protein regulating key step in cancer metastasis
Researchers have identified a specialized protein that appears to help prevent tumor cells from entering the bloodstream and spreading to other parts of the body.
"We have discovered that this protein, TRPM7, senses the pressure of fluid flowing in the circulation and stops the cells from spreading through the vascular system," said Kaustav Bera, a Johns Hopkins University PhD candidate in chemical and biomolecular engineering and a lead author of the study, which was done with colleagues at the University of Alberta and Universitat Pompeu Fabra.
"We found that metastatic tumor cells have markedly reduced levels of this sensor protein, and that is why they efficiently enter into the circulation rather than turning away from fluid flow," said Bera.
The findings, published in END
