Cancer cells in hypoxia usually make adaptive changes in cellular metabolism, such as altered autophagy. This might be a cause of enhanced radioresistance in some types of cancer. In this study, we investigated hypoxia-responsive miRNAs in two prostate cancer cell lines (DU145 and PC3). This study firstly reported that hypoxia induces further downregulation(More)
The aim of the current study was to investigate the role of polymorphisms in DNA repair pathways on the clinical outcome of gastric cancer patients treated with platinum-based chemotherapy. A total of 380 gastric cancer patients treated with platinum-based chemotherapy were included in the present study. * 502T>G), and XRCC3 rs861539 (Thr241Met) were(More)
The tumor-suppressive let-7 family of microRNAs (miRNAs) has been previously identified to induce cell apoptosis, proliferation‑inhibition and suppression of the self‑renewal capacities of cancer stem cells (CSCs). However, let‑7‑mediated sensitization of tumors to radiation treatment remains to be investigated fully in triple negative breast cancer (TNBC),(More)
To evaluate the diagnosis significance of single high-frequency ultrasonography and mammography and combination therapy of both on breast cancer. 352 cases of female breast cancer patients were selected from The First Affiliated Hospital of Zhengzhou University from January 2012 to December 2014. Among the 352 patients, 124 patients had only performed(More)
