Tissue transglutaminase (TG2) is involved in Ca(2+)-dependent aggregation and polymerization of proteins. We previously reported that TG2 mRNA is up-regulated in epithelial ovarian cancer (EOC) cells compared with normal ovarian epithelium. Here, we show overexpression of the TG2 protein in ovarian cancer cells and tumors and its secretion in ascites fluid(More)
Tissue transglutaminase (TG2), an enzyme that catalyzes Ca(2+)-dependent aggregation and polymerization of proteins, is overexpressed in ovarian cancer cells and tumors. We previously reported that TG2 facilitates tumor dissemination using an i.p. xenograft model. Here we show that TG2 modulates epithelial-to-mesenchymal transition (EMT), contributing to(More)
PURPOSE To investigate histamine-induced changes in the phosphorylation of myosin light chain (MLC) and its influence on the barrier integrity of corneal endothelial cells through altered contractility of the actin cytoskeleton. METHODS Experiments were performed in cultured bovine corneal endothelial cells (BCECs). Phosphorylation of MLC, which increases(More)
PURPOSE Phosphorylation of myosin light chain (MLC) is essential for the contractility of the actin cytoskeleton, which regulates barrier integrity, adhesion, and migration. This study was conducted to investigate the effect of benzalkonium chloride (BAK), a preservative in topical ophthalmic formulations, on MLC phosphorylation in primary cultures of(More)
A functionalized nanohydrogel siRNA delivery system and a mouse model of serous ovarian cancer were used to test predictions from previous cell line studies that knockdown of EGFR (epidermal growth factor receptor) may be of clinical significance in the treatment of epithelial tumors especially with respect to the enhancement of platinum based therapies.(More)
We described a novel handheld device (termed FMTPen) for three-dimensional (3D) fluorescence molecular tomography (FMT). The FMTpen is characterized by its bendable structure and miniaturized size (10 mm in diameter) that can be potentially used as an intraoperative tool for the detection of tumor margins and for image-guided surgery. Several phantom(More)
The contribution of lipid metabolic pathways to malignancy is poorly understood. Expression of the fatty acyl-CoA synthe-tase ACSVL3 was found to be markedly elevated in clinical malignant glioma specimens but nearly undetectable in normal glia. ACSVL3 levels correlated with the malignant behavior of human glioma cell lines and glioma cells propagated as(More)
