Competition for iron influences host-pathogen interactions. Pathogens secrete small iron-binding moieties, siderophores, to acquire host iron. In response, the host secretes siderophore-binding proteins, such as lipocalin 24p3, which limit siderophore-mediated iron import into bacteria. Mammals produce 2,5-dihydroxy benzoic acid, a compound that resembles a bacterial siderophore. Our data sugge...
To gain insight into the in vivo role of estrogen, we isolated estrogen receptor-positive cells from normal human breast tissue using a recombinant adenovirus that expresses green fluorescence protein in response to estrogen. We compared the global gene expression profile of these estrogen receptor-positive cells with that of various normal and cancerous mammary epithelial cells and identified ...
Background and Aims: This study aimed to investigate the amount of Neutrophil gelatinase-associated lipocalin (NGAL) in patients' urine with Gram-positive cocci infections Materials and Methods: The microbial culture was prepared from 100 urine samples and the results were recorded. The genus and bacterial were species identified and an antibiogram test was conducted to investigate their resis...
Background & objectives: Lipocalin family proteins, have been identified as adipokines associated with obesity, type 2 diabetes (T2D) and the metabolic syndrome. Exercise training and active compounds of plants have potency as antidiabetic that can be used for treating T2D. We have evaluated the effect of exercise training and Momordica chianti L. on Retinol binding protein-4(RBP4), Fatty aci...
Intracellular iron regulates gene expression by inhibiting the interaction of iron regulatory proteins (IRPs) with RNA motifs called iron-responsive elements (IREs). To assay this interaction in living cells we have developed two fluorescent IRE-based reporters that rapidly, reversibly, and specifically respond to changes in cellular iron status as well as signaling that modifies IRP activity. ...
Neutrophil gelatinase-associated lipocalin (NGAL) is a 25 kD lipocalin that is covalently bound to matrix metalloproteinase (MMP)-9 produced by neutrophils [1]. NGAL in blood or bronchoalveolar lavage fluid (BALF) may reflect neutrophilic inflammation in the lungs [2, 3], and it is highly induced in injured epithelial cells, including those in the lung [4]. Possible roles for neutrophilic infla...
The lipocalins are secreted proteins that bind small organic molecules. Scn-Ngal (also known as neutrophil gelatinase associated lipocalin, siderocalin, lipocalin 2) sequesters bacterial iron chelators, called siderophores, and consequently blocks bacterial growth. However, Scn-Ngal is also prominently expressed in aseptic diseases, implying that it binds additional ligands and serves additiona...
Lipocalin-2 (LCN2), a secreted glycoprotein belonging to the lipocalin superfamily was reported to participate in various biological processes including cell migration, cell survival, inflammatory responses, and insulin sensitivity. LCN2 is expressed in the multiple tissues such as kidney, liver, uterus, and bone marrow. The receptors for LCN2 were additionally found in microglia, astrocytes, e...
A gel-based proteomics approach was used to screen for proteins of differential abundance between the saliva of smokers and those who had never smoked. Subjecting precipitated proteins from whole human saliva of healthy non-smokers to two-dimensional electrophoresis (2-DE) generated typical profiles comprising more than 50 proteins. While 35 of the proteins were previously established by other ...
The data herein is related to the research article entitled "Microbiota-inducible innate immune siderophore binding protein Lipocalin 2 is critical for intestinal homeostasis" (Singh et al., 2016) [1]. In the present article, we monitored dextran sodium sulfate (DSS)-induced colitis development upon Lipocalin 2 (Lcn2) neutralization, and examined the survival of Lcn2 deficient (Lcn2KO) mice and...
