BACKGROUND Cancer stem cells (CSCs) are believed to be 'seed cell' in cancer recurrence and metastasis. MicroRNAs (miRNAs) can play an important role in the progression of primary tumor towards metastasis by regulating the epithelial-mesenchymal transition (EMT). The goal of this study was to investigate the effect of miRNA-200c overexpression on the EMT,(More)
It has been well documented that both endogenous inflammatory mediator advanced glycation end products (AGEs) and exogenous inflammatory inducer lipopolysaccharide play key roles in the initiation and development of inflammatory diseases. However, the combined inflammation-stimulatory effect of AGEs and lipopolysaccharide on endothelial cells, and,(More)
BACKGROUND The human umbilical cord mesenchymal stem cells (hUCMSCs) have the ability to migrate into tumors and therefore have been considered as an alternative source of mesenchymal progenitors for the therapy of malignant diseases. The present study was aimed to investigate effect of hUCMSCs as vehicles for a constant source of transgenic interleukin-21(More)
Cancer stem cells (CSCs) are thought to be capable of surviving conventional chemotherapeutic treatments because the cells have more resistant to anticancer drugs than common cancer cells. Most in vitro studies in experimental cancer cells have been done in a two-dimensional (2D) monocultures, while accumulating evidence suggests that cancer cells behave(More)
AIM To investigate the effects of anti-ABCG2 monoclonal antibodies (mAbs) in combination with paclitaxel iron oxide nanoparticles (PTX-NPs) on CD138(-)CD34(-) multiple myeloma (MM) cancer stem cells (CSCs) in JJN3 cells. MATERIALS & METHODS PTX-NPs were prepared using the hydrophobic interaction of the polyoxypropylene chain and oleic acid on the surface(More)
In this study, the effect of drying temperature, from 50 °C to 90 °C, on the drying characteristics of powdered peanut shell was investigated, and an isothermal procedure was used to determine the moisture diffusivity and the activation energy. All the experiments were performed using a thermogravimetric analyzer (TGA) for rapidly achieving the isothermal(More)
OBJECTIVE Vascular calcification is an active deposition process of calcium phosphate which resembles bone formation and is highly regulated by osteoblast-like cells. Existing studies demonstrate that advanced glycation end-products (AGEs) may play a pathogenic role in the vascular calcification process. However, their mechanism remains poorly understood.(More)
BACKGROUND To explore the effects of downregulated multidrug-resistance P-glycoprotein (MDR1/ABCB1) and reversed multidrug-resistance in human A2780 ovarian cancer cells. MATERIALS AND METHODS Three shRNAs targeting the MDR1 gene were synthesized, and cloned into plasmid pSUPER-enhanced green fluorescent protein 1 (EGFP1). The formed(More)
Cancer cells behave differently in a three-dimensional (3D) cell culture compared with in the conventional two-dimensional (2D) one. Accumulated evidences indicate that the characteristics of cancer stem cells (CSCs) are different from common cancer cells due to their ability to produce tumors and resist chemoradiation. The objective of this work was to(More)
BACKGROUND Progress has been made against early events of malignant transformation and drug resistance associated with epithelial ovarian cancer; uncontrolled metastases, however, still accounts for most patient deaths. The molecular mechanism that regulates the process of epithelial ovarian cancer metastases is not yet clearly understood. The purpose of(More)
