Breast cancer is the most common malignant tumor in women worldwide. Breast tumors mostly exhibit aberrant gene expression and DNA hypermethylation patterns that predispose the disease. Understanding the genetic and epigenetic factors that contribute to breast cancer development is important to identify novel diagnostic and prognostic markers. SCARA5: Scavenger receptor class A, member 5; is a member of the scavenger receptor family located on chromosome 8p21 which is a frequently deleted region in human cancers...

Paracetamol overdosing may cause liver injury including fulminant liver failure due to generation of the toxic metabolites, N-acetyl-p-benzoquinone imine (NAPQI) and p-benzoquinone (p-BQ). Herein, the chelating agent, N,N'-Bis(2-mercaptoethyl)isophthalamide (NBMI), was examined for its potential ability to entrap NAPQI and p-BQ and to prevent paracetamol-induced liver injury. Both NBMI and the conventional paracetamol antidote N-Acetyl cysteine (NAC) were investigated with regard to their abilities to scavenge the NAPQI and p-BQ in a Transient Receptor Potential Ankyrin 1 (TRPA1)-dependent screening assay...

Because macrophages are involved in the pathology of many diseases, targeting delivery of therapeutic molecules to macrophages is important issue. Polyrotaxanes (PRXs) composed of multiple cyclodextrins threaded with a linear polymer were utilized as a therapeutic agent for metabolic disease and for regulating cellular metabolism. For targeting delivery of PRXs to macrophages, carboxyethyl ether group-modified PRXs (CEE-PRXs) are designed for promoting interaction to macrophage scavenger receptor class A (SR-A)...

Class B scavenger receptors, scavenger receptor B1 (SR-B1) and cluster of differentiation 36 (CD36), are broadly expressed cell-surface proteins and are believed to serve as multifaceted players in lipid and lipoprotein metabolism in mammals. Because of its ability to recognise distinct odour-active volatile compounds and its presence in murine olfactory epithelium, CD36 has recently emerged as a participant in the detection of odorants within the nasal cavity. However, there have been no attempts to assess whether SR-B1 has such a role...

Macrophages are essential for innate immunity and inflammatory responses and differentiate into various functional phenotypes. Tribbles homolog 1 ( Trib1 ), a member of the mammalian Tribbles homolog pseudokinase family, has been implicated in regulation of cell differentiation, proliferation and metabolism, but its role in macrophage biology has not been fully elucidated. Here, we investigated the consequences of Trib1 deficiency on macrophage functions and M1/M2 polarization. Bone marrow-derived macrophages (BMDMs) from Trib1 -deficient ( Trib1 -/- ) mice exhibited elevated phagocytic capacity, correlating with up-regulation of several scavenger receptors...

Vaspin (visceral adipose tissue-derived serine protease inhibitor) was recently identified as a novel adipocytokine with insulin-sensitizing effects. Serum vaspin levels are reported either increased or decreased in patients with coronary artery disease. Our translational research was performed to evaluate the expression of vaspin in human coronary atherosclerotic lesions, and its effects on atherogenic responses in human macrophages and human aortic smooth muscle cells (HASMC), as well as aortic atherosclerotic lesion development in spontaneously hyperlipidemic Apoe −/− mice, an animal model of atherosclerosis...

Craniofacial muscle pain, such as spontaneous pain and bite-evoked pain, are major symptoms in patients with temporomandibular disorders and infection. However, the underlying mechanisms of muscle pain, especially mechanisms of highly prevalent spontaneous pain, are poorly understood. Recently, we reported that transient receptor potential vanilloid 1 (TRPV1) contributes to spontaneous pain but only marginally contributes to bite-evoked pain during masseter inflammation. Here, we investigated the role of transient receptor potential ankyrin 1 (TRPA1) in spontaneous and bite-evoked pain during masseter inflammation, and dissected the relative contributions of TRPA1 and TRPV1...

US28 is a broad-spectrum constitutively active G protein-coupled receptor encoded by the human cytomegalovirus (HCMV). It binds and scavenges multiple CC-chemokines as well as CX3 CL1 (fractalkine) by constitutive receptor endocytosis to escape immune surveillance. We herein report the design and characterization of a novel library of US28-acting commercially available ligands based on the molecular descriptors of two previously reported US28-acting structures. Among these, we identify compounds capable of selectively recognizing CCL2-and CCL4-, but not CX3 CL1-induced receptor conformations...

CD36 scavenger receptor is expressed in a subpopulation of olfactory sensory neurons (OSNs). These neurons express canonical olfactory signaling machinery; however, not all odorant receptors (ORs) are coexpressed with CD36. In situ hybridization (ISH) enables the detection of nucleic acids in tissues, cells, or isolated chromosomes. The development of nonradioactive and stable labeling probes almost 30 years ago, allowed to routinely perform this technique employing different labeling strategies in one experiment...

The transformation of macrophages into lipid loaded foam cells is a critical and early event in the pathogenesis of atherosclerosis. Several recent reports highlighted that induction of TLR4 signaling promotes macrophage foam cell formation; however, the underlying molecular mechanisms have not been clearly elucidated. Here, we found that the TLR4 mediated inflammatory signaling communicated with mTORC2-Akt-mTORC1 metabolic cascade in macrophage and thereby promoting lipid uptake and foam cell formation. Mechanistically, LPS treatment markedly upregulates TLR4 mediated inflammatory pathway which by activating mTORC2 induces Akt phosphorylation at serine 473 and that aggravate mTORC1 dependent scavenger receptors expression and consequent lipid accumulation in THP-1 macrophages...

Uncovering the biological role of nuclear receptor peroxisome proliferator-activated receptors (PPARs) has greatly advanced our knowledge of the transcriptional control of glucose and energy metabolism. As such, pharmacological activation of PPARγ has emerged as an efficient approach for treating metabolic disorders with the current use of thiazolidinediones to improve insulin resistance in diabetic patients. The recent identification of growth hormone releasing peptides (GHRP) as potent inducers of PPARγ through activation of the scavenger receptor CD36 has defined a novel alternative to regulate essential aspects of lipid and energy metabolism...

Galectin-3-binding protein (Gal-3BP) is a ubiquitous and multifunctional secreted glycoprotein originally identified and mainly studied in the context of neoplastic transformation and cancer progression. However, Gal-3BP expression is induced in viral infection and by a multitude of molecules that either mimic or are characteristic for an ongoing inflammation and microbial infection, such as IFN-α, IFN-β, IFN-γ, TNF-α, poly(I:C), dsRNA, and dsDNA. Furthermore, Gal-3BP belongs to the scavenger receptor cysteine-rich (SRCR) domain-containing protein family, by virtue of its N-terminal SRCR domain...

BACKGROUND: Scavenger receptor class B type I (SR-BI) plays a key role in high density lipoproteins (HDL) metabolism. SR-BI deficiency in mice results in enhanced susceptibility to atherosclerosis with abnormal large, cholesterol enriched, and functional impaired HDL. This study was to characterize the protein markers of dysfunctional HDL in SR-BI deficient (SR-BI-/- ) mice and to test if the defective of HDL might be affected by probucol treatment. METHODS: Shotgun proteomics and 2-D gel electrophoresis were performed to examine the profile of HDL protein and distribution of HDL particles isolated from SR-BI-/- mice...

Glial immune activity is a key feature of Alzheimer's disease (AD). Given that the blood factors heme and hemoglobin (Hb) are both elevated in AD tissues and have immunomodulatory roles, here we sought to interrogate their roles in modulating amyloid β (Aβ)-mediated inflammatory activation of astrocytes. We discovered that heme and Hb suppress immune activity of primary mouse astrocytes by reducing expression of several proinflammatory cytokines (e.g. RANTES) and the scavenger receptor CD36, and reducing internalization of Aβ1-42 by astrocytes...

Many scientific findings have been reported on the beneficial function of reactive oxygen species (ROS) in various cellular processes, showing that they are not just toxic byproducts. The double-edged role of ROS shows the importance of the regulation of ROS level. We report a gene, rrsRLK (required for ROS-scavenging receptor-like kinase), that encodes a cytoplasmic RLK belonging to the non-RD kinase family. The gene was identified by screening rice RLK mutant lines infected with Xanthomonas oryzae pv. oryzae ( Xoo ), an agent of bacterial leaf blight of rice...
