BACKGROUND The purpose of this study was to investigate the association between ARMS2/HTRA1, CFH, and C3 gene polymorphisms and retinal angiomatous proliferation (RAP), an infrequent and severe form of exudative age-related macular degeneration, which is characterized by intraretinal neovascularization. METHODS Diagnosis of RAP was based on fundus photographs, images of fluorescein and indocy...
AIM To show the mutation in HTRA1 gene in a patient suffering from CARASIL syndrome with degenerated spine as a component of the disease. MATERIAL AND METHODS We identified a family that one of the members had CARASIL syndrome in eastern Turkey and collected venous blood from available persons. The HTRA1 gene sequenced in all family members. RESULTS C to T transition at position 1108 (c.110...
Single nucleotide polymorphism (SNP), rs11200638, in the promoter of HTRA1 has recently been shown to increase the risk for AMD. In order to investigate the association of this HTRA1 polymorphism and the bilaterality of AMD, we genotyped rs11200638 in control, unilateral, and bilateral advanced AMD patients. The A allele for SNP rs11200638 in HTRA1, was significantly more prevalent in bilateral...
INTRODUCTION Pre-eclampsia (PE) is the most serious syndrome of human pregnancy and it is potentially life-threatening for both mother and fetus. The aim of the study was to identify the role of high temperature requirement A1 (HtrA1) in pre-eclampsia. MATERIAL AND METHODS One hundred consecutive pregnancies complicated by PE and 100 normal controls were included in our study. The changes in ...
High temperature requirement A1 (HtrA1) is a secreted protease involved in placental development. Fibronectin (FN) is involved in important process such as wound healing, cell adhesion and spreading, growth, migration, and differentiation. The purpose of this study was to analyse the expression patterns of HtrA1 in relationship to FN and to the key growth zones of placenta such as mesenchymal v...
PURPOSE Multiple studies demonstrate a strong association between three variants at chromosome 10q26 - rs10490924, del443ins54, and rs11200638 - near the age-related maculopathy susceptibility 2 (ARMS2) and high-temperature requirement factor A1 (HTRA1) genes with susceptibility to age-related macular degeneration (AMD). In different reports, the del443ins54 and rs11200638 variants are suggeste...
BACKGROUND Degrading enzymes play an important role in the process of disc degeneration. The objective of this study was to investigate the correlation between the expression of high temperature requirement serine protease A1 (HtrA1) in the nucleus pulposus and the T2 value of the nucleus pulposus region in magnetic resonance imaging (MRI). MATERIAL AND METHODS Thirty-six patients who had under...
Purpose: To examine the common single-nucleotide polymorphisms in complement factor H (CFH), LOC387715, and HTRA1 genes as potential risk factors for exudative age-related macular degeneration (AMD) in the mainland Chinese. Methods: A cohort of 121 unrelated patients with exudative AMD and 132 ageand sexmatched control subjects, all unrelated ethnic Chinese from Northern China, enrolled in this...
High-temperature requirement A1 (HTRA1) is a secreted serine protease reported to play a role in the development of several cancers and neurodegenerative diseases. Still, the mechanism underlying the disease processes largely remains undetermined. In age-related macular degeneration (AMD), a common cause of vision impairment and blindness in industrialized societies, two synonymous polymorphism...
PURPOSE Identification of genetic factors for age-related macular degeneration (AMD) is of crucial importance in this common cause of blindness. Exudative AMD is rapidly progressive and usually associated with severe prognosis. Our purpose was to investigate this association on locus 10q26 in a case-control study including French patients specifically affected with exudative AMD. METHODS Poly...
