Vascular endothelial growth factor (-460 C/T, +405 G/C, and +936 C/T) polymorphisms and endometriosis risk in Tunisian population.

The vascular endothelial growth factor (VEGF), a major angiogenic factor, is known to play an important role in the development of endometriosis. The aim of this study was to investigate the association of three VEGF (-460 C/T, +405 G/C, and +936 C/T) polymorphisms with the risk of endometriosis in the Tunisian population. This study includes 105 women with endometriosis and 150 women with no laparoscopic evidence of disease.

CCR2-64I polymorphism is associated with Non-Small Cell Lung Cancer in Tunisian patients.

Single nucleotide polymorphism (SNPs) in genes coding for chemokines may be associated with some cancer. The purpose of this study was to investigate the impact of CCR2-64I and CXCL12-3'A SNPs on the susceptibility and the clinicopathological characteristics of NSCLC (Non-Small Cell Lung Cancer) in the Tunisian population. 170 NSCLC patients and 225 healthy controls screened by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis were enrolled.

Glutathione S-transferase M1 and T1 gene polymorphisms and risk of endometriosis in Tunisian population.

Objective: An association between endometriosis and the glutathione S-transferase M1 (GSTM1)- and GSTT1-related genes has been proposed on account of the detoxification properties of the GST enzymes. The aim of the present study was to investigate whether the polymorphisms and null mutations are associated with the susceptibility to endometriosis.

Methods: The study included 105 women with endometriosis and 150 healthy women with no laparoscopic evidence of disease.

Association of vitamin D receptor FokI and ApaI polymorphisms with lung cancer risk in Tunisian population.

Many studies reported that Vitamin D Receptor (VDR) gene polymorphisms might influence the cancer risk due to their antiproliferative, antiangiogenic, and apoptotic effects. The aim of this study was to explore the genetic association of VDR polymorphisms with lung cancer risk in Tunisian population. The genotype and haplotype frequencies of four VDR polymorphisms, FokI (rs2228570), BsmI (rs1544410), ApaI (rs7975232) and TaqI (rs731236) were studied using polymerase chain reaction and restriction fragment length polymorphism analysis in 240 patients with lung cancer and 280 healthy controls.

Interleukin-17A and -17F genes polymorphisms in lung cancer.

Interleukin-17 (IL-17) is a proinflammatory cytokines produced by T helper 17 (Th17) cells, which plays an important role in both innate and adaptive immune systems. Genetic variants in the IL-17 genes may influence the immunopathogenesis of many cancers. In our study, we investigated the association of three single-nucleotide polymorphisms (SNPs: -152 G/A, 7488 A/G and 7383 A/G) in the IL-17A and IL-17F genes with lung cancer risk, in the Tunisian population.

Tumor necrosis factor gene polymorphisms in Tunisian patients with non-small cell lung cancer.

Background: Lung cancer (LC) is one of the most lethal malignant disorders; it is generally divided into two groups: small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC). In our present study we have been interested to NSCLC. Several approaches were adopted to study the etiology or pathophysiology of this disease.

Association of IL-8 gene polymorphisms with non small cell lung cancer in Tunisia: A case control study.

Interleukin 8 (IL-8), is a proinflammatory chemokine, has been reported to have angiogenic activity and to be responsible for tumor-associated angiogenesis in several cancers. In this study, we aimed to study the (IL-8) gene polymorphism in relation with risk development of non small cell lung cancer in Tunisian patient. Two single nucleotide polymorphisms (-251T/A [rs4073], +781C/T [rs2227306]) of the IL-8 gene were screened in 170 patients with NSCLC and 225 healthy controls by PCR-RFLP.
