ISG15: A novel therapeutic target to slow breast cancer cell motility
Date:1/11/2012

sions in breast cancer cells. Targeted knockdown of both ISG15 and UbcH8 resulted in reconstitution of the cytoskeletal architecture. Dr. Desai said "Disruption of cellular architecture is a hallmark of cancer. The ISG15 pathway is also elevated in a variety of tumors. Our results therefore reveal that the ISG15 pathway which is aberrantly elevated in tumors could disrupt cell architecture and contribute to breast cancer cell motility". "Because the cellular architecture is conserved and the ISG15 pathway is constitutively activated in tumor cells of different lineages, our observations in breast cancer must hold true for many other tumors".

If ISG15 confers motility to tumor cells in vivo, as suggested in this manuscript, then Dr. Desai concludes that "strategies to decrease ISGylation could provide a therapeutic advantage for patients diagnosed with metastatic tumors overexpressing the ISG15 pathway".

Dr. Steven R. Goodman, Editor-in-Chief of Experimental Biology and Medicine said that "these intriguing studies by Desai and colleagues suggests that modulation of the ISG15 pathway may provide future therapeutic targets for breast cancer and other metastatic tumors".
