Retinal blood vessel-origin yes-associated protein (YAP) governs astrocytic maturation via leukaemia inhibitory factor (LIF).

Objectives: To testify that endothelial cells (ECs) induce astrocyte maturation by leukaemia inhibitory factor (LIF) secretion.

Materials And Methods: In vivo experiments, mice bearing floxed alleles of YAP were crossed with mice expressing a Cre recombinase driven by the endothelial Tek promoter (Tek-Cre) to finally obtain the following three genotypes: YAP , Tek-Cre; YAP , Tek-Cre; and YAP . Retinal vascularization and astrocyte network were evaluated by whole-mount fluorescence and Western blotting.

MicroRNA-30b regulates the polarity of retinal ganglion cells by inhibiting semaphorin-3A.

Purpose: Retinal ganglion cell (RGC) polarity plays an important role in optic nerve regeneration. This study was designed to investigate whether semaphorin-3A (Sema3A) is involved in the regulation of RGC polarity and Sema3A protein expression.

Methods: Cultured primary RGCs were treated with Fc-Sema3A or Sema3A siRNA or transfected with purified miR-30b recombinant adenoassociated virus (rAAV).

The link between apolipoprotein E, presenilin 1, and kinesin light chain 1 gene polymorphisms and age-related cortical cataracts in the Chinese population.

Purpose: To study whether presenilin 1 (PSEN1), apolipoprotein E (APOE), and kinesin light chain 1 (KLC1) genotypes are associated with the risk of developing age-related cortical cataracts in the Han Chinese population.

Methods: We collected and analyzed the blood samples of 227 cortical cataract patients and 263 controls. Genotyping was performed by direct sequencing after PCR amplification, and allele frequencies were tested for the Hardy-Weinberg equilibrium.

Amino-Nogo inhibits optic nerve regeneration and functional recovery via the integrin αv signaling pathway in rats.

Background: Nogo-A, a major myelin-associated inhibitor, can inhibit injured optic nerve regeneration. However, whether Amino-Nogo is the most important functional domain of Nogo-A remains unknown. This study aimed to identify the role of Amino-Nogo following optic nerve injury, and the mechanism of the Amino-Nogo-integrin αv signaling pathway in vivo.

Inhibition of retinal ganglion cell axonal outgrowth through the Amino-Nogo-A signaling pathway.

Nogo-A is a myelin-derived inhibitor playing a pivotal role in the prevention of axonal regeneration. A functional domain of Nogo-A, Amino-Nogo, exerts an inhibitory effect on axonal regeneration, although the mechanism is unclear. The present study investigated the role of the Amino-Nogo-integrin signaling pathway in primary retinal ganglion cells (RGCs) with respect to axonal outgrowth, which is required for axonal regeneration.

Association between MTHFR C677T polymorphism and primary open-angle glaucoma: a meta-analysis.

Epidemiological studies have evaluated the association between methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism and primary open-angle glaucoma (POAG) risk. However, the results remain conflicting. The aim of this study was to investigate the association between MTHFRC677T polymorphism and POAG risk.

Clinical features of ankylosing spondylitis associated with acute anterior uveitis in Chinese patients.

Aim: To characterize the clinical features, diagnosis, treatment and prognosis of uveitis associated with ankylosing spondylitis (AS) in Chinese patients.

Methods: Two hundred and three patients with uveitis associated with AS followed-up in the Third Military Medical University Daping Hospital between 2005 and 2010 were retrospectively evaluated in this study. Complete ophthalmological examinations were evaluated at baseline and during the follow-up period.

[Expression of Nogo-A and Nogo receptor in neonatal rats visual system during development].

Objective: To study the expression of Nogo-A and Nogo receptor (NgR) in the development of neonatal rats retinal and visual cortex and their effects on the development of central nervous system (CNS).

Methods: Immunohistochemical staining method was used to detect the expression of Nogo-A and NgR in neonatal rats retinal and visual cortex at 1, 3, 7, 14, 28, 56 days after birth. One-way Anova was used to analyze the results of Western blot analysis of Nogo-A and NgR in neonatal rats visual cortex.

A case of circumscribed choroidal hemangioma in Sturge-Weber syndrome in China.

We present a case of circumscribed choroidal hemangioma (CCH) in Sturge-Weber syndrome in a 30-year-old woman with congenital port-wine stains on the left side of face involving the upper eyelid, cheek and the nose, and she had undergone facial hemangioma surgery 3 years ago suggestive of Sturge-Weber syndrome. She presented with a 1-month history of rapidly decreased visual acuity (VA) to counting fingers in the left eye which had no prior history of visual problem. And there was no evidence of glaucoma.

Bietti crystalline dystrophy with bilateral macular holes.

Objective: Bietti crystalline dystrophy is a rare form of tapetoretinal degeneration associated with retinal crystalline deposits. However, Bietti crystalline dystrophy is extremely unusually associated with macular hole formation. A 32-year-old man with Bietti crystalline dystrophy and bilateral macular holes is described.
