MiRNA-21 linked to tumor suppressor loss, herceptin resistance

Researchers found that MiRNA-21 interferes with trastuzumab (Herceptin) therapy by blocking the PTEN gene, leading to tumor suppressor loss and increased resistance to the drug. Overexpression of miRNA-21 was correlated with poor patient response to Herceptin and disease progression in HER2-positive breast cancer patients.
