Background: Vitiligo is an acquired skin disorder that selectively destroys melanocytes in epidermis with an unknown etiology.   Objective: To investigate the exon 1 A49G polymorphism of cytotoxic T lymphocyte antigen-4 (ctla-4) gene in vitiligo patients.   Methods: The A49G polymorphism was detected by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) method in 101...

Background: The incidence of malignant melanoma continues to rise worldwide. While ultraviolet (UV) radiation is a risk factor for melanoma, recent reports have shown link between alcohol consumption and incidence. Alcohol metabolized highly carcinogenic acetaldehyde (AcAH) detoxified by aldehyde dehydrogenase 2 (ALDH2). Therefore, AcAH accumulates when individuals with low ALDH2 activity take ...

PURPOSE Vogt-Koyanagi-Harada (VKH) syndrome is an autoimmune disease. The monocyte chemoattractant protein-1 (MCP-1) gene has been implicated in the pathogenesis of certain autoimmune diseases. The aim of this study was to examine whether a MCP-1 polymorphism was associated with VKH syndrome. METHODS A case-control analysis was performed using genomic DNA samples from 307 VKH patients and 319...

The diacylglycerol acyltransferase 1 gene (DGAT1) was identified as a strong candidate gene affecting mutton quality traits in sheep. Single nucleotide polymorphism creates a single base mutation (C to T) in AGCT site of endonuclease AluI. DGAT1 is one of the candidate genes to improve carcass characteristics in feedlot animals. In order to study area T487C in exon 17 of the DGAT1 polymorphism,...

The authors aimed to determine whether 2 functional polymorphisms in the heme oxygenase-1 (HO-1) gene promoter are associated with type 2 diabetes mellitus (T2DM). A Chinese case-control study involving 1,103 newly diagnosed T2DM patients, 371 patients with impaired glucose regulation (IGR), and 1,615 controls was performed (December 2004-December 2007). A (GT)(n) microsatellite polymorphism an...

As ecologically and economically, marine gastropod mollusca are highly significant in the benthic ecosystems. Among gastropods, Umbonium vestiarium (Linnaeus, 1758) is a key stone species Adult from coastal areas Bangladesh including Cox’s Bazar, Sonadia St. Martin’s Islands typically range 1-2 cm, exhibit extensive colour polymorphism.

Background and Objective: Studies suggests that matrix metalloproteinase (MMP)-2-1306 C/T and MMP-1-1607 1G/2G polymorphisms affect the risk of prostate cancer. However, the conclusions remain controversial and no pooled evidence of this topic has been published. Therefore, we aimed to perform a meta-analysis to shed some light on the controversial conclusion pertaining to the associations of M...

Matrix metalloproteinases (MMPs) facilitate cellular invasion by degrading the extracellular matrix, and their regulation is partially dependent on transcription. Binding sites for members of the Ets family of transcription factors are present within MMP promoters and are potent positive regulators. We report a single nucleotide polymorphism at -1607 bp in the MMP-1 promoter, where an additiona...
