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)
Bladder cancer is the second most common genitourinary tumor and constitutes a very heterogeneous disease. Molecular and pathologic studies suggest that low-grade noninvasive and high-grade invasive urothelial cell carcinoma (UCC) arise via distinct pathways. Low-grade noninvasive UCC represent the majority of tumors at presentation. A high proportion of(More)
BACKGROUND Chronic inflammation is considered as an important factor in the pathogenesis of lung cancer. The presence of inflammatory cells and higher levels of pro-inflammatory cytokines in the tumor microenvironment and their surrounding tissues is gaining much importance in research. MATERIALS AND METHODS One hundred ninety NSCLC cases and 200 age,(More)
Among various polymorphic variants of TP53 gene, codon 72 polymorphism (Arg72Pro) has been found to be associated with cancer susceptibility, but only few studies have investigated their effect on bladder cancer risk. A case-control study was conducted and we observed the genotype distribution of TP53 Arg72Pro SNP, to elucidate the possible role of this SNP(More)
BACKGROUND Vitamin D regulates many biological processes including bone metabolism, innate immune response, and cell proliferation and differentiation by binding to its receptor VDR. Vitamin D receptor (VDR) gene polymorphisms have been associated with many cancers like breast, colorectal, prostate, and skin. The main aim of this study was to determine(More)
Breast cancer shows geographical variation in its incidence, even within areas of ethnic homogeneity. Kashmir valley (India), over past few years, witnesses an increase in incidence and occurrence of familial, early onset, and male breast cancer in its unexplored ethnic population. Here, we make a preliminary attempt to estimate the nature and frequency of(More)
OBJECTIVE Specific acquired HRAS mutations have been found to predominate in bladder cancer, and HRAS T81C polymorphism has been determined to contribute the risk of various cancers, including bladder cancer. MATERIALS AND METHODS We screened the exon 1and 2 of HRAS and frequently detected polymorphism at nucleotide 81T to C (exon 1). A case-control study(More)
OBJECTIVE The aim of our study was to determine the genetic associations between polymorphisms of the IL1β gene (-511C/T and +3953C/T) and IL6 gene (-174G/C) with disease susceptibility and severity in patients with rheumatoid arthritis (RA) in ethnic Kashmiri population. METHODS Allele and genotype frequencies of IL1β -511 C/T, IL1β +3953 C/T and IL6(More)
Pleural effusion is one of the commonest presentations of tuberculosis, the clinical manifestations being typically abrupt resembling bacterial pneumonia. Since delayed hypersensitivity is the underlying immune response, bacterial load is very low. Owing to these facts, tuberculous pleurisy as an extra-pulmonary disease poses a diagnostic dilemma. The(More)
INTRODUCTION A strong association between chronic infection, inflammation, and cancer has been suggested. DISCUSSION Helicobacter pylori, a microaerophilic gram negative bacterium, infects about half the world's population. It has been defined as a definitive carcinogen in the pathogenesis of gastric cancer. H. pylori evades the host immune responses and(More)
