| Mechanism Description | We detected significant downregulation of miR-200 family members, including miR-200b, -200a and -429 in CDDP-resistant cells. The simultaneous reduction of these miRNAs is thought to be associated with increased DNA methylation of their upstream CpG islands. | |||

| Mechanism Description | Inhibiting EMT by overexpressing miR-200 did not impact lung metastasis development. However, EMT cells significantly contribute to recurrent lung metastasis formation after chemotherapy. These cells survived cyclophosphamide treatment due to reduced proliferation, apoptotic tolerance, and elevated expression of chemoresistance-related genes. Overexpression of miR-200 abrogated this resistance. | |||

| Mechanism Description | In the validation set, miR-200a (area under the curve = 0.881, sensitivity = 94.1%, specificity = 76.7%) and miR-210 (area under the curve = 0.851, sensitivity = 88.2%, specificity = 72.1%) showed high diagnostic accuracy for distinguishing sensitive group from resistant group. Furthermore, the plasma level of miR-200a was significantly associated with the stage in surgery (P = .035), and the high level of miR-210 expression was associated with internal organ metastasis (liver, lung, and brain; P = .024). Conclusions: Plasma miR-200a and miR-210 could be effective biomarkers for the prediction of chemotherapy resistance in metastatic breast cancer patients. | |||

| Mechanism Description | Furthermore, we show that microRNA-451 regulates the expression of multidrug resistance 1 gene. More importantly, transfection of the MCF-7/DOX-resistant cells with microRNA-451 resulted in the increased sensitivity of cells to DOX, indicating that correction of altered expression of miRNA may have significant implications for therapeutic strategies aiming to overcome cancer cell resistance. | |||

| Mechanism Description | The Mig6-mediated reduction of EGFR occurs concomitantly with a TGFbeta-induced EMT-associated kinase switch of tumor cells to an AkT-activated state, thereby leading to an EGFR-independent phenotype that is refractory to EGFR TkI. the ratio of the expression levels of Mig6 and miR200c is highly correlated with EMT and resistance to erlotinib. Moreover, analyses of primary tumor xenografts of patient-derived lung and pancreatic cancers carrying wild type EGFR showed that the tumor Mig6(mRNA)/miR200 ratio is inversely correlated with response to erlotinib in vivo. | |||
