Fine mapping and sequence analysis reveal a promising candidate gene encoding a novel NB-ARC domain derived from wild rice () that confers bacterial blight resistance.

Bacterial blight disease of rice caused by pv. () is one of the most serious constraints in rice production. The most sustainable strategy to combat the disease is the deployment of host plant resistance.

Expression profiling of luminal B breast tumor in Indian women.

Purpose: In this study, we aimed at profiling of luminal B breast cancer specific gene expression pattern in Indian women using mRNA-seq and validation based on TCGA expression data.

Methods: RNA isolated from luminal B tumor and adjacent normal tissues was used for library construction and sequencing. Reference-based assemblies of these reads were used for differential gene expression analysis using DeSeq2.

Genotypic and haplotype analysis of Interleukin-6 and -18 gene polymorphisms in association with clinicopathological factors in breast cancer.

Cytokines are multifunctional glycoproteins that play a vital role in the tumor microenvironment and progression of breast cancer. Genetic polymorphisms may influence the immune responses restrained by pro- and anti-inflammatory cytokine expression in tumors. Hence, the present study evaluated the contribution of Interleukin (IL) 6 (rs1800797, rs1800796, and rs1800795) and IL18 (rs1946518, rs187238, and rs549908) genotypes and their haplotypes to the risk, progression of breast cancer in South Indian population.

PCSK9 genetic (rs11591147) and epigenetic (DNA methylation) modifications associated with PCSK9 expression and serum proteins in CAD patients.

Introduction: Proprotein convertase subtilisin/kexin type 9 (PCSK9) genetic polymorphisms play a significant role in cholesterol homeostasis. Therefore, we aimed to investigate the association of PCSK9 genetic variations NM_174936.3:c.

Collagenase-1 (-1607 1G/2G), Gelatinase-A (-1306 C/T), Stromelysin-1 (-1171 5A/6A) functional promoter polymorphisms in risk prediction of type 2 diabetic nephropathy.

Type 2 Diabetic Nephropathy (DN) is a common multifactorial disorder. Degradation of glomerular basement membrane (GBM) by matrix metalloproteases (MMPs) is a key event in the progression of renal disease. A functional polymorphism at position -1607 1G/2G, -1306 C/T and -1171 5A/6A has been shown to alter the transcriptional activity of MMP-1, MMP-2, and MMP-3 respectively, and also associated with several diseases contributing to inter-individual differences in susceptibility to type 2 DN.

MMP 1 circulating levels and promoter polymorphism in risk prediction of coronary artery disease in asymptomatic first degree relatives.

Coronary artery disease (CAD) remains to be the prominent health problem in India, and its incidence is growing in developing countries as well. Matrix metalloproteinase 1 (MMP 1) is highly expressed in disruption-prone shoulder regions of the fibrous plaques. The present study aims to investigate association of MMP 1 gene polymorphisms (-1607 1G/2G) and serum circulating levels with CAD.

Influence of gelatinase B polymorphic variants and its serum levels in atherosclerosis.

Aim: Atherosclerosis, the underlying pathology of cardiovascular disease, is a common, multifactorial disorder with both genetic and environmental components as risk factors. Gelatinase B, also known as MMP-9, is one of the matrix metalloproteinases that is highly expressed in the disruption-prone regions of atherosclerotic plaques. It has been hypothesized that a genetic variation affecting the expression or activity of MMP-9 influences the susceptibility and progression of atherosclerosis.

IL-10 high producing genotype predisposes HIV infected individuals to TB infection.

Interleukin (IL-10), an anti-inflammatory cytokine, is known to have dual effect on the host immune system. One of these roles is that it provides an effective autoregulatory mechanism which protects the host from excessive inflammation and tissue damage which is in part initiated by the Th1 driven pro-inflammatory immune responses during infections (such as TB, HIV and malaria). However, though beneficial, this autoregulatory mechanism is at times exploited by pathogens which evade elimination by Th1 driven immune response leading to chronic infections.

Association of TAP 1 and 2 gene polymorphisms with human immunodeficiency virus-tuberculosis co-infection.

Major histocompatibility complex (MHC) class I binding peptides are carried from cytosol to the lumen of the endoplasmic reticulum (ER) by transporter associated with antigen processing (TAP), an integral ER membrane protein composed of two subunits, TAP1 and TAP2. Polymorphism in TAP genes may influence these proteins further affecting the antigen peptide presentation, indirectly resulting in the viral escape mechanism from cell-mediated immunity in human immunodeficiency virus (HIV). Our aim was to study the influence of these polymorphism in study groups with HIV-tuberculosis (TB) (n = 110), TB (n = 105), and HIV (n = 130) compared with healthy controls (n = 183), using the tetraprimer amplification refractory mutation system (ARMS)-polymerase chain reaction method.
