Lipocalins are a group of proteins that have been characterized in bacteria, invertebrate, and vertebrate animals. However, very little is known about plant lipocalins. We have previously reported the cloning of the first true plant lipocalins. Here we report the identification and characterization of plant lipocalins and lipocalin-like proteins using an integrated approach of data mining, expr...

PURPOSE The purpose of this article was to identify by mass spectrometry phosphocholine lipids in stimulated human tears and determine the molecules bound to tear lipocalin or other proteins. METHODS Tear proteins were separated isocratically from pooled stimulated human tears by gel filtration fast performance liquid chromatography. Separation of tear lipocalin was confirmed by SDS tricine g...

Our goal is to decipher which DNA sequences are required for tissue-specific expression of epididymal genes. At least 6 epididymis-specific lipocalin genes are known. These are differently regulated and regionalized in the epididymis. Lipocalin 5 (Lcn5 or mE-RABP) and Lipocalin 8 (Lcn8 or mEP17) are homologous genes belonging to the epididymis-specific lipocalin gene cluster. Both the 5 kb prom...

BACKGROUND Peroxisome proliferator-activated receptor-γ (PPAR-γ) agonist has a wide-ranging influence on multiple components of metabolic syndrome. The Otsuka Long-Evans Tokushima Fatty (OLETF) rat is a useful animal model of metabolic syndrome. To determine genes related to metabolic syndrome, we examined overlapping genes that are simultaneously decreased by PPAR-γ agonists and increased in O...

Genetic instability is strongly involved in cancer development and progression, and elucidating the mechanism could lead to novel therapeutics for preventing carcinogenesis. Philadelphia-negative myeloproliferative neoplasms (MPNs) are clonal myeloid disorders with a high prevalence of JAK2V617F mutation, and transformation to acute myeloid leukemia through accumulation of additional mutations ...

Why and when the immune system skews to Th2 mediated allergic immune responses is still poorly characterized. With two homologous lipocalins, the major respiratory dog allergen Can f 1 and the human endogenous, non-allergenic Lipocalin-1, we investigated their impact on human monocyte-derived dendritic cells (DC). The two lipocalins had differential effects on DC according to their allergenic p...

Neutrophil gelatinase associated lipocalin (NGAL), a constituent of neutrophil granules, is a member of the lipocalin family of binding proteins. NGAL can also be highly induced in epithelial cells in both inflammatory and neoplastic colorectal disease. NGAL is proposed to mediate inflammatory responses by sequestering neutrophil chemoattractants, particularly N-formylated tripeptides and possi...

In this study we characterized the human T cell-reactive sites of the major cow dander allergen, Bos d 2, a member of the lipocalin protein family. We showed that Bos d 2 contains only a limited number of epitopes. This is in contrast to many other allergens, which usually contain multiple T cell epitopes throughout the molecule. The epitopes of Bos d 2 were primarily concentrated in the conser...

background: serum levels of lipocalin 2 (lcn 2) and retinol-binding protein-4 (rbp 4), increase in type 2 diabetes mellitus (t2dm). we sought to determine whether serum lcn 2 and rbp 4 change after an intervention with omega-3 fatty acids supplementation in diabetic patients. methods: forty-five type 2 diabetic patients from iranian diabetic association in tehran, iran in 2013 were randomly rec...
