Benzodiazepines (BZDs), which bind with high affinity to gamma-aminobutyric acid type A receptors (GABAA-Rs) and potentiate the effects of GABA, are widely prescribed for anxiety, insomnia, epileptic discharge, and as anticonvulsants. The long-term use of BZDs is limited due to adverse effects such as tolerance, dependence, withdrawal effects, and impairments in cognition and learning. Addition...

BACKGROUND & AIMS Lipocalin 2 (Lcn2) is a multifunctional innate immune protein whose expression closely correlates with extent of intestinal inflammation. However, whether Lcn2 plays a role in the pathogenesis of gut inflammation is unknown. Herein, we investigated the extent to which Lcn2 regulates inflammation and gut bacterial dysbiosis in mouse models of IBD. METHODS Lcn2 expression was ...

Cervical carcinoma is the third-most common cause of cancer-related deaths in women worldwide. However, the molecular mechanisms underlying the metastasis of cervical cancer are still unclear. Oligonucleotide microarrays coupled with bioinformatics analysis show that cytoskeletal remodeling and epithelial-to- mesenchymal transition (EMT) are significant pathways in clinical specimens of cervica...

Various states of inflammation, including sepsis, are associated with hypoferremia, which limits iron availability to pathogens and reduces iron-mediated oxidative stress. Lipocalin 2 (Lcn2; siderocalin, 24p3) plays a central role in iron transport. Accordingly, Lcn2-deficient (Lcn2KO) mice exhibit elevated intracellular labile iron. In this study, we report that LPS induced systemic Lcn2 by 15...

Immune fibroblastic cell (IFC) subpopulations of dermal fibroblasts differentiate into adipocytes and provide skin immune defense in response to infection. To better understand the role these fibroblast subsets, we have undertaken a systematic analysis models inflammation. First, communication from mesenchymal, epithelial, bone-marrow derived cells was investigated using unbiased machine learni...

OBJECTIVE Adipose tissue inflammation and perturbation of adipokine secretion may contribute to the pathogenesis of cardiovascular diseases (CVD). Lipocalin-2 (LCN2), mainly released from adipocytes, has been shown to be positively associated with CVD in cross-sectional studies. We aimed to evaluate the association of LCN2 with CVD involving a population-based cohort recruited from the Shanghai...

Background: Performing sports activities along with nutritional interventions is recommended as an effective way to reduce inflammatory cytokines and improve insulin resistance in obese people. This study aimed evaluate the effect of aerobic exercise Ginkgo biloba herbal supplementation on lipocalin 2 (Lcn2) levels men. Materials Methods: For this purpose, 40 men Kashan were selected accessible...

Lipocalin-2 (LCN2), an iron-related protein well described to participate in the innate immune response, has been shown to modulate spine morphology and to regulate neuronal excitability. In accordance, LCN2-null mice are reported to have stress-induced anxiety. Here we show that, under standard housing conditions, LCN2-null mice display anxious and depressive-like behaviors, as well as cogniti...

Numerous bacteria cope with the scarcity of iron in their microenvironment by synthesizing small iron-scavenging molecules known as siderophores. Mammals have evolved countermeasures to block siderophore-mediated iron acquisition as part of their innate immune response. Secreted lipocalin 2 (Lcn2) sequesters the Escherichia coli siderophore enterobactin (Ent), preventing E. coli from acquiring ...

HER2-positive breast cancer initially responds to trastuzumab treatment, but over time, resistance develops and rapid cancer progression occurs, for which various explanations have been proposed. Here we tested the hypothesis that induction of the unfolded protein response (UPR) could override HER2 inhibition by trastuzumab, leading to the re-activation of growth signaling and the activation of...
