Copine3, a known calcium-dependent membrane binding protein, contains two tandem C2 domains and an A domain. This protein has been shown to interact with receptor tyrosine kinase 2 (ErbB2), but little is known concerning the physiological function of Copine3. To better understand its cellular function, we carried out a yeast twohybrid screen to find Copine3 binding partners. Among the identifie...

Circulating tumor cells (CTCs) have been shown in many studies as a possible biomarker for metastasis and may be instrumental for the spread of the disease. Despite advances in CTC capturing technologies, the low frequency of CTCs in cancer patients and the heterogeneity of the CTCs have limited the wide application of the technology in clinic. In this study, we investigated a novel microfluidi...

Even in the presence of oxygen most cancer cells convert glucose to lactate via pyruvate instead of performing oxidative phosphorylation (aerobic glycolysis-Warburg effect). Thus, it has been considered to shift pyruvate - the metabolite of aerobic glycolysis - to acetylCoA by activation of pyruvate dehydrogenase (PDH). AcetylCoA will then be metabolized by oxidative phosphorylation. Therefore,...

Trastuzumab has been widely used for the treatment of human epidermal growth factor receptor 2 (HER2)-overexpressing breast cancer, however, it cannot easily cross the blood-brain barrier (BBB) and is known to increase the incidence of brain metastases. In contrast, lapatinib has a low molecular weight and can cross the BBB and it could be useful to treat brain metastases in patients with HER2-...

Radiotherapy resistance remains a major obstacle for patients with breast cancer. miRNAs are important regulators in many biological processes including proliferation, apoptosis, invasion and metastasis and response to treatment in different types of tumors. Here, we describe the role of miRNA-144 in the regulation of radiotherapy sensitivity, migration and invasion of breast cancer cells. The ...

Recently, our research into hepatocellular carcinoma (HCC) has shown that the transcription factors Myeloid Zinc Finger-1 (MZF-1) and Ets-like-protein 1 are related to protein kinase C alpha (PKCα) expression. The purpose of this study was to determine the correlation of the expression of PKCαwith the expressions of Elk-1 and MZF-1 in various differentiated breast cancer cell lines: MDA- MB-231...
