Drugs may block metastasis-driving protein
Researchers have discovered a new, key component in the spread of lung cancer in the protein Jagged2 — which silences protective microRNA (miR-200) — as well as a likely way to block it with drugs now in clinical trial.
“We think metastasis is initiated by the tumor microenvironment,” says Jonathan Kurie, M.D., professor in MD Anderson’s Department of Thoracic/Head and Neck Medical Oncology and senior author on the paper.
“Cells metastasize in response to external cues, one of which is Jagged2,” says Yanan Yang, Ph.D., Kurie’s postdoctoral fellow and the study’s first author.
