Leprosy is an infectious disease caused by the obligate intracellular pathogen Mycobacterium leprae and remains endemic in many parts of the world. Despite several major studies on susceptibility to leprosy, few genomic loci have been replicated independently. We have conducted an association analysis of more than 1,500 individuals from different(More)
During nuclear DNA replication, proofreading-deficient DNA poly-merase a (Pol a) initiates Okazaki fragment synthesis with lower fidelity than bulk replication by proofreading-proficient Pol d or Pol e. Here, we provide evidence that the exonuclease activity of mammalian flap endonuclease (FEN1) excises Pol a replication errors in a MutSa-dependent,(More)
The FUT2 gene encodes the enzyme alpha (1,2) fucosyltransferase, which determines expression of blood-group antigens on mucosal epithelial cell surfaces and in secretions. Homozygotes for a specific stop mutation in FUT2 (nonsecretors) cannot produce this enzyme and thus are unable to express blood group antigens. Nonsecretor status is associated with a(More)
A number of isolates of Vibrio cholerae were examined with respect to their (i) surface hydrophobicity as measured by hydrophobic interaction chromatography, (ii) capacity to agglutinate erythrocytes, and (iii) ability to bind to an ion-exchange matrix. V. cholerae isolates, cultured under a variety of growth conditions, were conspicuously hydrophobic. The(More)
Type 2 diabetes (T2D) is a syndrome of multiple metabolic disorders and is genetically heterogeneous. India comprises one of the largest global populations with highest number of reported type 2 diabetes cases. However, limited information about T2D associated loci is available for Indian populations. It is, therefore, pertinent to evaluate the previously(More)
BACKGROUND Mycobacterium leprae is the etiologic pathogen that causes leprosy. The outcome of disease is dependent on the host genetic background. METHODS We investigated the association of 51 single-nucelotide polymorphisms (SNPs) in anti-inflammatory cytokines (IL-10, TGFB1, IL-6, IL-4, and IL-13) and receptors (IL-10RA, IL-10RB, TGFBR1, TGFBR2, IL-6R,(More)
Leprosy is a chronic infectious disease caused by Mycobacterium Leprae, where the host genetic background plays an important role toward the disease pathogenesis. Various studies have identified a number of human genes in association with leprosy or its clinical forms. However, non-replication of results has hinted at the heterogeneity among associations(More)
Host immune response against Mycobacterium leprae plays an important role in providing resistance to infection and disease progression. Genome-wide linkage and association studies suggest the possibility of multiple risk loci within HLA (6p21.3) region. Any systematic study of relevance within the histocompatibility complex of importance in host immune(More)
BACKGROUND Genome-wide studies have identified both human leucocyte antigen (HLA) and non-HLA regions in association with leprosy. Involvement of novel functional loci within these regions has been proposed by us earlier. METHODS We investigated the role of 23 single nucleotide polymorphisms (SNPs) in IL12B and IL12RB2 in a total of 2345 individuals from(More)
Genuine racial differences in prostate cancer (PCa) biology have been considered among the potential reasons to explain PCa disparities. There is no animal model to represent all aspects of human PCa and, more specifically, to be used for PCa disparity research. The lack of a spontaneously transformed in vitro cell-based model system has been a significant(More)
