PURPOSE: CD133/ prominin 1 is a cancer stem cell marker associated with cancer progression and patient outcome in a variety of solid tumours, but its role in invasive breast cancer (BC) remains obscure. The current study aims to assess the prognostic value of CD133 expression in early invasive BC. METHODS: CD133 mRNA was assessed in the METABRIC cohort and at the proteomic level using immunohistochemistry utilising a large well-characterised BC cohort. Association with clinicopathological characteristics, expression of other stem cell markers and patient outcome were evaluated...

The importance of the Type-1 helper immune response in the development of Vitiligo (Vit), and of chemokine receptor (CXCR)3 receptor and its chemokine monokine induced by interferon (IFN)-γ(MIG) has been shown by several studies. MIG/ interferon (IFN)-γ-inducible protein 10 (IP10) /CXCR3 axis mediated T-cell recruitment into the skin in Vit is an early event in the progression of the disease. MIG and IP10 circulating levels are increased in progressive Vit. It has been suggested that MIG and CXCR3 could be novel targets of future therapeutical approaches...

Monokine induced by interferon (IFN)-γ (MIG) / chemokine (C-X-C motif) ligand 9 (CXCL)9 is involved in the pathogenesis of psoriatic arthritis (PsA). It was demonstrated that both blood plasma-derived dendritic cells (pDCs) and pDCs isolated from rheumatoid arthritis (RA) and PsA synovial fluid (SF), expressed CXC receptor (R) 3 and CXCR4, and that the chemotaxis of blood-derived pDCs is stimulated by MIG, (IFN)-γ-inducible protein 10 (IP-10)/CXCL10, IFN-inducible T-cell α chemoattractant (I-TAC) )/CXCL11 and stromal cell-derived factor 1 (SDF-1)/ CXCL12, present in RA and PsA SF...

OBJECTIVE: Recent evidence suggesting an important role of gut-derived inflammation in brain disorders has opened up new directions to explore the possible role of the gut-brain axis in neurodegenerative diseases. Given the prominence of dysbiosis and colonic dysfunction in patients with Parkinson's disease (PD), we propose that toll-like receptor 4 (TLR4)-mediated intestinal dysfunction could contribute to intestinal and central inflammation in PD-related neurodegeneration. DESIGN: To test this hypothesis we performed studies in both human tissue and a murine model of PD...

INTRODUCTION: Skeletal muscle dysfunction is a clinically important complication of pulmonary arterial hypertension (PAH). Growth/differentiation factor 15 (GDF-15), a prognostic marker in PAH, has been associated with muscle loss in other conditions. We aimed to define the associations of GDF-15 and muscle wasting in PAH, to assess its utility as a biomarker of muscle loss and to investigate its downstream signalling pathway as a therapeutic target. METHODS: GDF-15 levels and measures of muscle size and strength were analysed in the monocrotaline (MCT) rat, Sugen/hypoxia mouse and in 30 patients with PAH...

Horse serum is commonly used as an additive to support the maintenance of hematopoietic progenitor cells in culture. However, the wide variability in the performance of different lots calls for parallel testing of multiple batches over extended periods of culture. Identification of the serum components that determine hematopoietic support would therefore save considerable time and effort and would help to standardize culture procedures. We report here that the ability of horse serum to support the self-renewal of multipotent murine hematopoietic progenitor FDCP-Mix cells is correlated to the concentration of specific fatty acid products of phospholipase A2 and more closely to the spectrum of eicosanoids generated by their further processing through cyclooxygenase and lipoxygenase pathways...

Protein kinase RNA-like Endoplasmic Reticulum Kinase (PERK) is an endoplasmic reticulum stress sensor that possesses pro-survival capability and contributes to cell homeostasis and survival. Leucine-rich repeat-containing G-protein coupled receptor 5 (Lgr5) has been recognized as a stem cell marker in intestinal epithelial cells. To determine whether PERK modulates the proliferation of intestinal stem cells, we investigated the effects of PERK knock-down on intestinal Lgr5-positive stem cells in mice. Lgr5-EGFP knock-in mice were fed with lentivirus-PERK shRNA twice a day for three days...

BACKGROUND: /Aims. In cholangiocarcinoma, early metastatic spread via lymphatic vessels often precludes curative therapies. Cholangiocarcinoma invasiveness is fostered by an extensive stromal reaction, enriched in cancer-associated fibroblasts (CAF) and lymphatic endothelial cells (LEC). Cholangiocarcinoma cells recruit and activate CAF by secreting PDGF-D. Here we investigated the role of PDGF-D and liver myofibroblasts in promoting lymphangiogenesis in cholangiocarcinoma. METHODS: Human cholangiocarcinoma specimens were immunostained for podoplanin (LEC marker), α-SMA (CAF), VEGF-A, VEGF-C, and their cognate receptors (VEGFR2, VEGFR3)...

Alcoholic liver disease is associated with high morbidity and mortality, and treatment options are limited to date. Augmenter of liver regeneration (ALR) may protect against hepatic injury caused by chemical poisons, including ethanol. Autophagy appears to positively influence survival in cases of liver dysfunction, though the mechanisms are poorly understood. Here, we investigated the impact of ALR-induced autophagy in vitro and in vivo in an ethanol-induced model of acute liver injury. Decreased serum levels of alanine aminotransferase and aspartate aminotransferase and reduced histological lesions revealed that mice overexpressing ALR experienced less liver damage than wild-type mice...

Around 75% of neurons in laminae I-II of the mouse dorsal horn are excitatory interneurons, and these are required for normal pain perception. We have shown that four largely non-overlapping excitatory interneuron populations can be defined by expression of the neuropeptides neurotensin, neurokinin B (NKB), gastrin-releasing peptide (GRP) and substance P. In addition, we recently identified a population of excitatory interneurons in glabrous skin territory that express dynorphin. The calcium-binding protein calretinin is present in many excitatory neurons in this region, but we know little about its relation to these neuropeptide markers...

BACKGROUND: Laryngeal squamous cell carcinoma (LSCC) is strongly associated with tobacco use, but recent reports suggest an increasing incidence of LSCC in patients without traditional risk factors, suggesting an alternative etiology of tumorigenesis. The purpose of this study is to characterize this non-smoking population and to compare immunohistochemical markers in tumor specimens from non-smokers and smokers with LSCC. METHODS: A retrospective chart review of patients with LSCC at Johns Hopkins Hospital (JHH) was performed...

The human RAD9A protein is required for successful execution of the G2/M DNA damage checkpoint. Along with RAD1 and HUS1, RAD9A exists in a heterotrimeric ring-shaped complex which is necessary for activation of the CHK1 checkpoint kinase. RAD9A is also required for proper localization of both TopBP1 and the Claspin adaptor protein during the DNA damage response. We have shown large, RAD9A-dense nuclear foci containing several members of the homologous recombination pathway as well as BRCA1 and the DNA damage marker γH2AX...

We analyzed the clinicopathological, immunohistochemical and cytogenetic features of 106 extranodal (EN) diffuse large B-cell lymphomas (DLBCLs) from stomach (34 cases), intestine (10), cervico-cephalic region (11), central nervous system (13), testes (21), skin (8), and miscellaneous sites (9). Hans' algorithm and the immunohistochemical double expressor score (DES) for MYC and BCL2 were applied to all cases. A subset of fifty-eight cases were analyzed with fluorescent in situ hybridization (FISH) with specific break apart probes for BCL6, MYC, BCL2, CCND1, BCL10 and MALT1 genes...

Hepatosplenic T-cell lymphoma (HSTL) is a rare subtype of peripheral T-cell lymphoma predominantly seen in young males. This disease presents with isolated hepatosplenomegaly and thrombocytopenia with sinusoidal infiltration of liver and sinusal infiltration of spleen. Immunophenotype shows positivity for CD3, CD7, TCRγδ or TCRαβ, CD38 and double negative for CD4, CD8, TdT, CD5, and CD56. Isochromosome 7q with or without trisomy 8 is seen in HSTL. Recently, ring chromosome 7 has also been identified as a new abnormality...

Diabetic retinopathy (DR) is one of the most devastating complications of diabetes mellitus. When exposed to high glucose (HG), retinal epithelial cells undergo profound alterations both morphologically and functionally in a well-conserved process known as epithelial-to-mesenchymal transition (EMT). The mechanism governing HG-induced EMT in retinal epithelial cells is not completely understood. Here we report that treatment with 25 mM glucose led to EMT in retinal pigmented epithelial cells (RPE) characterized by a simultaneous down-regulation of E-Cadherin (encoded by CDH1) and up-regulation of alpha smooth muscle actin (encoded by ACTA2)...

Cartilage oligomeric matrix protein (COMP) is a large, multifunctional extracellular protein that, when mutated, is retained in the rough endoplasmic reticulum (ER). This retention elicits ER stress, inflammation, and oxidative stress, resulting in dysfunction and death of growth plate chondrocytes. While identifying the cellular pathologic mechanisms underlying the murine mutant (MT)-COMP model of pseudoachondroplasia, increased midline-1 (MID1) expression and mammalian target of rapamycin complex 1 (mTORC1) signaling was found...

Monocytes are important mediators of the innate immunity by recognizing and attacking especially bacterial pathogens but also play crucial roles in various inflammatory diseases, including vascular inflammation and atherosclerosis. Maturation, differentiation and function of monocytes have been intensively explored for a long time in innumerable experimental and clinical studies. Monocytes do not represent a uniform cell type but could be further subdivided into subpopulations with distinct features and functions...

The production of dopaminergic (DA) neurons from stem cells holds a great promise for future clinical treatment of neurodegenerative diseases, such as Parkinson's disease (PD). Olfactory ecto-mesenchymal stem cells (OE-MSCs) derived from the adult human olfactory mucosa can be easily isolated and expanded in culture while maintaining their immense plasticity. In addition to reduced ethical concerns, OE-MSCs could be transplanted across allogeneic barriers, making them desirable stem cells for clinical applications...
