The vascular endothelial growth factor (VEGF) is a major mediator of angiogenesis involving tumor growth and metastasis. Polymorphisms in the VEGF gene may regulate VEGF production. In this case–control study, we investigated whether functional polymorphisms (+405 C > G and +936 C > T) in the VEGF gene are associated with the risk of lung cancer. Genomic(More)

The CYP1A1 category of enzymes plays a central role in the metabolic activation of major tobacco carcinogens. Several polymorphisms within the CYP1A1 locus have been identified and have been shown to be associated with lung cancer risk, particularly in Asian populations. Here we focused on the influence of three polymorphisms on lung cancer in ethnic(More)
BACKGROUND The gene for the vascular endothelial growth factor (VEGF), which promotes angiogenesis and permeability, is polymorphic. The aim of the present study was to evaluate the relationship between +936C>T and +404C>G polymorphism of VEGF with risk of esophageal cancer in the Kashmiri population in India. MATERIALS AND METHODS 150 esophageal cancer(More)
INTRODUCTION Interleukin 1 beta (IL- 1β), a key proinflammatory cytokine encoded by the interleukin 1 beta gene, has been associated with chronic inflammation and plays an important role in lung inflammatory diseases including lung cancer. Elevated levels of Interleukin 1proteins, in particular interleukin 1 beta greatly enhance the intensity of the(More)
BACKGROUND The DNA repair gene XRCC1 Arg399Gln gene polymorphism has been found to be implicated in the development of various cancers, including colorectal cancer (CRC), in different populations. We aimed to determine any association of this polymorphism with the risk of CRC in Kashmir. MATERIALS AND METHODS A total of 120 confirmed cases of CRC and 146(More)
To study the possible role of proinflammatory interleukin 6 -174 G>C (rs 1800795) and -634 C>G (rs 1800796) polymorphism in the pathogenesis of non-small cell lung cancer (NSCLC). A total of 190 NSCLC patients and 200 healthy controls were evaluated for polymorphic analysis of -174 G/C and -634 C/G by PCR-RFLP followed by DNA sequencing. A significant(More)
BACKGROUND Even after adequate immunosuppression therapy, acute rejection continues to be the single most important cause of graft dysfunction after renal transplantation. Renal allograft biopsy continues to be the reference standard, though certain clinical and biochemical parameters are helpful in assessment of these patients. Renal allograft rejection is(More)
BACKGROUND Chronic obstructive pulmonary disease (COPD) is characterized by an interaction of various environmental influences especially cigarette smoking and genetic determinants. The prevalence of this disease is ever increasing and characterization of the genetic determinants of the disease has been undertaken globally. The 'A disintegrin and(More)
VEGF contains several polymorphic sites known to influence its expression. We examined the possible association between+405(-634)C>G,+936C>T,-2578C>A and lung cancer in 199 Kashmiri patients and 401 healthy controls. VEGF+405CG,+936CT+TT and-2578CA genotypes were significantly associated with lung cancer risk compared to VEGF+405CC,+936CC and-2578AA+CC(More)
