PURPOSE To investigate vascular endothelial growth factor (VEGF) gene polymorphisms in unrelated Taiwan Chinese patients with late age-related macular degeneration (AMD) and controls. DESIGN Retrospective case-control study. METHODS We enrolled 190 late AMD patients and 180 age-matched and gender-matched controls. Late AMD was classified as either dry(More)
PURPOSE Diabetic retinopathy (DR) is a microvascular complication of diabetes with a complex multifactorial pathogenesis. The aim of this study was to identify the susceptibility genes that increase the risk of DR in type 2 diabetes (T2D) and to further elucidate the underlying mechanism of DR pathogenesis. DESIGN A case-control study. PARTICIPANTS We(More)
BACKGROUND The effects of baicalein on SCC-4 human tongue cancer cells were examined to better understand its effect on apoptosis and associated possible signal pathways in vitro. MATERIALS AND METHODS Apoptosis induction, reactive oxygen species (ROS), cytoplasmic Ca2+, mitochondrial membrane potential (MMP) and caspase-3 activity were analyzed using the(More)
PURPOSE Transforming growth factor-beta (TGFbeta), a multifunctional growth factor that plays a key role in the remodeling of scleral tissue, may be involved in the predisposition and pathophysiology of high myopia. Our aim was to examine the association between myopia and the polymorphisms within codon 10 of the TGFbeta1 gene. METHODS This was a case(More)
The enzymatically active region of amylopullulanase from Thermoanaerobacterium saccharolyticum NTOU1 (TsaNTOU1Apu) was identified by truncation mutagenesis. Two truncated TsaNTOU1Apu enzymes, TsaNTOU1ApuM957 and TsaNTOU1ApuK885, were selected and characterized. Both TsaNTOU1ApuM957 and TsaNTOU1ApuK885 showed similar specific activities toward various(More)
Cancer metastasis involves multiple processes which may complicate clinical management and even lead to death. Matrix metalloproteinases (MMPs) play an important role in cancer cell invasion, metastasis and angiogenesis, depending on whether agents can inhibit MMPs which could lead to inhibition of the migration and invasion of cancer cells. Curcumin, the(More)
Genetic factors and the influence of superoxide are known to play roles in the etiology of glaucoma. We evaluated the association between primary open angle glaucoma (POAG) and two polymorphisms in the epithelial nitric oxide synthase (eNOS) gene, and one polymorphism in the myeloperoxidase (MPO) gene. We enrolled 66 patients with POAG and 100 healthy(More)
BACKGROUND Hypoxia and nitric oxide (NO) play important roles in the onset and progression of glaucoma. Vascular endothelial growth factor (VEGF) is one of the main factors responsive to hypoxia and NO. In this study, we investigated the association between the BstUI C/T VEGF gene polymorphism and primary open angle glaucoma (POAG). METHODS 60 POAG(More)
Type I interferons (IFNs) are potent inducers of antiviral and antiproliferative activities in vertebrates. IFNs cause activation of genes encoding antiviral proteins, such as p56 from the IFN-stimulated gene family. There are six tetratricopeptide repeat (TPR) motifs located at the N-terminal sequence of p56. Since TPR motifs are known to participate in(More)
The cytotoxicity of berberine on C6 rat glioma cells indicated that berberine induced morphological changes and caused cell death through G2/M arrest and apoptosis. While undergoing apoptosis, there was a remarkable accumulation of G2/M cells with the upregulatoin of Wee1 but it also inhibited cyclin B, CDK1 and Cdc25c that led to G2/M arrest. Along with(More)
