BACKGROUND Systemic sclerosis (SSc) is characterized by excessive fibrosis and obliterative vascular lesions. Abnormal TGFbeta activation is implicated in the pathogenesis of SSc. Aberrant TGFbeta/Smad signaling can be controlled by stabilization of microtubules with paclitaxel. METHODS AND FINDINGS SSc and healthy human skin biopsies were incubated in(More)
PURPOSE To determine whether the overexpression of the proteasome catalytic beta5 subunit (PSMB5) can induce the expression of the catalytic subunits beta1 and beta2, enhance proteasome activity, and exert a cytoprotective effect in lens epithelial cells. METHODS Cells from the human lens epithelial cell line SRA01/04 (LECs) were stably transfected either(More)
PURPOSE. To evaluate the role of nerve growth factor (NGF) in retinal neovascularization in an oxygen-induced retinopathy (OIR) model. METHODS. The OIR model was established in C57BL/6J mice. NGF mRNA expression in retina was measured by quantitative real-time PCR. NGF expression in protein levels was evaluated by ELISA and immunostaining with NGF antibody.(More)
The proliferation and epithelial-mesenchymal transition (EMT) of retinal pigment epithelium (RPE) cells are the major pathological changes in development of proliferative vitreoretinopathy (PVR), which leads to severe visual impairment. Histone deacetylases (HDACs)-mediated epigenetic mechanisms play important roles in controlling various physiological and(More)
PURPOSE To compare the gene expression profile of trabecular meshwork (TM) and Schlemm's canal (SC) primary cultures and to identify promoters for targeting gene expression to specific cells in the outflow pathway. METHODS The differential gene expression profile of four human TM and three SC primary cultures was analyzed by gene microarrays (Affymetrix,(More)

OBJECTIVE Activation of the immune system via toll-like receptors (TLRs) is implicated in atherosclerosis, microvascular complications, and angiogenesis. However, the involvement of TLRs in inflammation-associated angiogenesis in ischemic neural tissue has not been investigated. The goal of this study is to determine the role of TLR4 signaling in(More)
PURPOSE Allergic conjunctivitis (AC) has been reported to induce the instability of the tear film. The tear protein and the lipid layer play important roles in maintaining the tear film. The aim of this study was to quantify the alteration of the major tear protein components and a lipid related protein secretory type IIa phospholipase A2 (sPLA2-IIa) in(More)
The repair and regeneration of tissues using endogenous stem cells represents an ultimate goal in regenerative medicine. To our knowledge, human lens regeneration has not yet been demonstrated. Currently, the only treatment for cataracts, the leading cause of blindness worldwide, is to extract the cataractous lens and implant an artificial intraocular lens.(More)
PURPOSE The purposed of this study was to investigate the fibroblast growth factor receptor 2 (FGFR2) gene in one Chinese family with Crouzon syndrome and to characterize the related clinical features. METHODS One family underwent complete ophthalmic examinations, and two patients were diagnosed with Crouzon syndrome. Genomic DNA was extracted from(More)
PURPOSE Angiogenesis accompanies several retinal pathologies that impair the inner blood-retinal barrier. Claudins are key structural and functional proteins of the barrier. This study compared the expression of claudins during the normal angiogenesis of development with that of oxygen-induced retinopathy. METHODS Real-time PCR was used to monitor mRNA(More)
