Biologists unravel drug-resistance mechanism in tumor cells date: october 22, 2015 source: massachusetts institute of technology summary: cancer biologists have discovered that targeting the rna-binding protein that promotes drug-resistance could lead to better cancer therapies.
The resistance of cancer cells to various therapeutic agents such efforts rely on understanding the molecular and cellular mechanisms that lead to drug resistance. Most drugs used to treat lung, breast and pancreatic cancers also promote drug-resistance and ultimately spur tumor growth researchers at the university of california, san diego school of medicine have discovered a biomarker called cd61 on the surface of drug-resistant tumors that appears responsible for inducing tumor metastasis by.
This paper outlines the current knowledge of mechanisms that promote or enable drug development of cancer progenitor cells or enable drug resistance. Mechanisms underlying acquired resistance to pathway-targeted drugs are being pursued largely through two basic strategies preclinically, cancer cell line models are being used to recapitulate the clinical experience, providing 'paired' samples of pretreatment drug-sensitive cells and post-treatment cells that manage to escape the consequences.
