In addition, 15481974 miR-27a plays an important role in mediating drug resistance by targeting multiple drug-resistance related genes. MiR-27a modulated MDR1/P-glycoprotein expression in human ovarian cancer cells by targeting HIPK2 [15] and could reverse the multidrug resistance of esophageal squamous cell carcinoma through regulation of MDR1 and apoptosis [14]. This study focused on the potential relationship between the expression level of miR-27a and various clinicopathological Tunicamycin characteristics of breast cancer patients, as well as disease-free survival and overall survival. It is worth noting that high levels of miR-27a appear to be significantly correlated with tumor size, lymph node metastases, distant metastasis and poor prognosis in patients with breast cancer. MiR-27a was up-regulated in patients presenting with metastases, suggesting that its up-regulation was acquired in the Nafarelin site course of tumor progression and, in particular, during the acquisition of metastatic potential. Our results showed that miR-27a and ZBTB10 expression were not correlated with receptor status. On the contrary, it was reported that miR-27a indirectly regulates estrogen receptora expression and hormone responsiveness in MCF-7 breast cancer cells through the suppression of ZBTB10 [30]. To understand these conflicting results, the difference between clinical observation and in vitro experiments should be considered. After dividing the patients by the cut-off method, a multivariate Cox proportional hazard regression analysis revealed that miR-27a overexpression had a significantly worse prognostic impact (P = 0.003) on the overall survival of breast cancer patients independent of tumor size (P = 0.000). These results indicate that, as an independent risk factor, miR-27a could serve as a pr.It could promote the migration of pancreatic cancer cells by targetingTable 2.
