چکیده
INTRODUCTION Polymorphic variants of MCP-1 and RANTES genes and their protein serum levels have been implicated in the increased risk and severity of several malignancies. However, the subject has not been explored in basal cell carcinoma (BCC) patients so far. AIM To investigate the association between monocyte chemoattractant protein 1 (MCP-1) (-2518 A/G) and RANTES (-403 G/A) polymorphism and risk and clinical course of BCC. MATERIAL AND METHODS The study group consisted of 150 unrelated patients with BCC and 140 healthy, unrelated, age- and sex-matched volunteers. The polymorphisms were analysed using the amplification refractory mutation system polymerase chain reaction method (ARMS-PCR) and single specific primer-polymerase chain reaction (SSP-PCR). Serum cytokine levels were measured with ELISA. RESULTS The presence of the MCP-1 -2518 GG genotype was statistically more frequent in BCC patients and it increased the risk of BCC (OR = 2.63, p = 0.003). Genotype -330 GG was statistically more common in patients with less advanced tumours (OR = 2.8, p = 0.017). Monocyte chemoattractant protein 1 serum level was statistically higher with GG genotype. In the BCC group MCP-1 serum levels were decreased. Neither polymorphic variants of RANTES nor the chemokine serum concentration differed significantly between the study groups. CONCLUSIONS These findings suggest that -2518 A/G MCP-1 polymorphism may be involved in BCC pathogenesis.

Recovery from hepatitis B virus (HBV) infection depends on the cellular immune responses. Chemokines and their receptors play significant roles in immune defense. This study was undertaken to investigate the association between HBV infection and single nucleotide polymorphisms (SNPs) of genes for the chemokines and their receptors. Between March 2002 and February 2004, a total of 957 single eth...

Systemic lupus erythematosus (SLE) is a systemic, autoimmune disorder. Monocyte chemoattractant protein 1 (MCP-1), a chemokine involved in the recruitment and migration of monocytes/macrophages, has been shown to be increased in the plasma of SLE patients. The aim of our study was to evaluate the possible association of the polymorphism -2518 of the MCP-1 gene with the risk of developing SLE, m...

Background & Aims: Behcet’s disease (BD) is an inflammatory vasculitis of unclear etiology. MCP-1 gene is a member of the C-C chemokines family that is a chemotactic factor for monocytes. The results obtained have shown that the -2518A/G polymorphism of MCP-1 gene is associated with BD. The aim of this study was to evaluate the possible involvement of this polymorphism and Behcet&rsq...

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...

Recent study in a group of German patients with SSc has implicated the SNP in the MCP-1 gene (-2518 A to G) as a factor of susceptibility to SSc. Reflecting the need for replication of genetic association studies, we investigated if this SNP is associated with SSc in another Caucasian population. MCP-1 -2518 A/G genotypes were determined using PCR-SSP in 46 SSc patients and in 449 healthy subje...
