mSEL-1L is a highly conserved ER-resident type I protein, involved in the degradation of misfolded peptides through the ubiquitin-proteasome system (UPS), a pathway known to control the plasticity of the vascular smooth muscle cells (VSMC) phenotype and survival. In this article we demonstrate that mSEL-1L deficiency interferes with the murine embryonic vascular network, showing particular irregularities in the intracranic and intersomitic neurovascular units and in the cerebral capillary microcirculation. During murine embryogenesis, mSEL-1L is expressed in cerebral areas known to harbor progenitor neural cells, while in the adult brain the protein is specifically restricted to the stem cell niches, co-localizing with Sox2 and Nestin...

Chemokines play an important role in regulating the complex immune system at the maternal-fetal interface during pregnancy. Among various chemokines, C-C motif chemokine ligand 2 (CCL2) plays a role in the recruitment of immune regulatory cells to implantation sites within the endometrium. In cattle, CCL2 is abundantly expressed in the uterine endometrium. However, its intracellular signaling has not been identified. In this study, we examined the effects of CCL2 on bovine endometrial (BEND) cell proliferation...

Chrysin is mainly found in passion flowers, honey, and propolis acts as a potential therapeutic and preventive agent to inhibit proliferation and invasion of various human cancer cells. Although chrysin has anti-carcinogenic effects in several cancers, little is known about its functional roles in ovarian cancer which shows poor prognosis and chemoresistance to traditional therapeutic agents. In the present study, we investigated functional roles of chrysin in progression of ovarian cancer cells using ES2 and OV90 (clear cell and serous carcinoma, respectively) cell lines...

Endothelial progenitor cells (EPCs) are a sub-population of bone marrow-derived mononuclear cells that are released in circulation to restore damaged endothelium during its physiological turnover or rescue blood perfusion after an ischemic insult. Additionally, they may be mobilized from perivascular niches located within larger arteries' wall in response to hypoxic conditions. For this reason, EPCs have been regarded as an effective tool to promote revascularization and functional recovery of ischemic hearts, but clinical application failed to exploit the full potential of patients-derived cells...

The G2-M transition of the cell cycle requires the activation of members of the Cdc25 dual specificity phosphatase family. Using Xenopus oocyte maturation as a model system, we have previously shown that chelation of transition metals blocks meiosis progression by inhibiting Cdc25C activation. Here, using approaches that allow for the isolation of very pure and active recombinant Cdc25C, we show that Cdc25C does not bind zinc as previously reported. Additionally, we show that mutants in the disordered C-terminal end of Cdc25C are poor initiators of meiosis, likely due to their inability to localize to the proper sub-cellular location...

Celiac disease is a multifactorial autoimmune chronic inflammatory disorder affecting approximately one percent of the worldwide population. In such patients, ingestion of gluten proteins from cereals like wheat, barley and rye causes damage of the small intestine mucosa, with potentially severe consequences. Onset of the disease in predisposed individuals is believed to require a still not clearly identified external trigger, such as viral infections. A very recent study has begun to shed light on a possible mechanistic basis for this hypothesis, and surprisingly linked intestinal infections caused by common reoviruses to the onset of celiac disease...

We previously demonstrated that the nuclear form of Glutathione Peroxidase 4 (nGPx4) has a peculiar distribution in sperm head, being localized to nuclear matrix and acrosome and that sperm lacking nGPx4 are more prone to decondensation in vitro. In this study we have hypothesized that sperm retained acetylated histones and nGPx4 are implicated in paternal chromatin decondensation and male pronucleus formation at fertilization. Indeed, significant higher amounts of acetylated histone H4 and acetylated histone H3 were observed by both immunofluorescence and western blotting in nGPx4-KO sperm vs WT ones...

Osteoclasts are multinucleated cells formed by fusion of preosteoclasts (POCs) derived from cells of the monocyte/macrophage lineage. We have reported a culture system that supports the formation of POCs from stroma-depleted rat bone marrow cells. Global gene expression analysis of this culture system identified genes highly expressed in POCs. Here, we have analyzed the expression and function of one of these highly expressed genes, prostate transmembrane protein androgen induced 1 (Pmepa1), a target of TGF-β and binds Nedd4 ubiquitin ligase, which plays a role in intracellular trafficking...

Apelin is an endogenous ligand of seven-transmembrane G protein-coupled receptor APJ. Apelin and APJ are distributed in various tissues, including the heart, lung, kidney, and even in tumor tissues. Studies show that apelin mRNA is highly expressed in the inner stripe of kidney outer medulla, which plays an important role in process of water and sodium balance. Additionally, more studies also indicate that apelin/APJ system exerts a broad range of activities in kidney. Therefore, we review the role of apelin/APJ system in kidney diseases such as renal fibrosis, renal ischemia/reperfusion injury, diabetic nephropathy, polycystic kidney disease and hemodialysis...

Bone marrow stromal cells (BMSCs) are multipotent cells that can differentiate into adipocytes and osteoblasts. Inadequate BMSC differentiation is occasionally implicated in chronic bone metabolic disorders. However, specific signaling pathways directing BMSC differentiation have not been elucidated. Here, we explored the roles of spleen tyrosine kinase (Syk) in BMSC differentiation into adipocytes and osteoblasts. We found that Syk phosphorylation was increased in the early stage, whereas its protein expression was gradually decreased during the adipogenic and osteogenic differentiation of two mouse mesenchymal stromal cell lines, ST2 and 10T(1/2), and a human BMSC line, UE6E-7-16...

HSPA2, a poorly characterized member of the HSPA (HSP70) chaperone family, is a testis-enriched protein involved in male germ cell differentiation. Previously, we revealed that HSPA2 is present in human stratified epithelia, including epidermis, however the contribution of this protein to epithelial biology remained unknown. Here, we show for the first time that HSPA2 is expressed in basal epidermal keratinocytes, albeit not in keratinocytes exhibiting features attributed to primitive undifferentiated progenitors, and participates in the keratinocyte differentiation process...

Osteolysis is the main limiting cause for the survival of an orthopedic prosthesis and is accompanied by an enhancement in osteoclastogenesis and inflammation, due by wear debris formation. Unfortunately therapeutic treatments, besides revision surgery, are not available.The aim of the present study was to evaluate the effects of Pulsed ElectroMagnetic Fields (PEMFs) and platelet rich plasma (PRP), alone or in combination, in an in vitro model of osteolysis. Rats peripheral blood mononuclear cells were cultured on Ultra High Molecular Weight Polyethylene particles and divided into 4 groups of treatments: 1) PEMF stimulation (12 hours/day, 2...

Profound alterations in the lipid profile of raft and non-raft plasma membrane microdomains were found when RAW264.7 macrophages were supplemented with polyunsaturated fatty acids (PUFAs) in physiologically relevant concentrations. For the first time lipids in the detergent-free isolated membrane domains of phagocytic immune cells were characterized by mass spectrometry. The extent of remodeling of the membrane lipids differed with different n3 and n6 PUFA supplements. The mildest effects were detected for -linolenic acid (LNA) and linoleic acid (LA), the C18 precursors of the n3 and n6 families, respectively...

Endoplasmic reticulum (ER) stress, a common cellular stress response, is closely related to the activation of autophagy that is an important and evolutionarily conserved mechanism for maintaining cellular homeostasis. Autophagy induced by ER stress mainly includes the ER stress-mediated autophagy and ER-phagy. The ER stress-mediated autophagy is characterized by the generation of autophagosomes that include worn-out proteins, protein aggregates, and damaged organelles. While the autophagosomes of ER-phagy selectively include ER membranes, and the double membranes also derive, at least in part, from the ER...

The esophagus is a pivotal organ originating from anterior foregut that links the mouth and stomach. Moreover, its development involves precise regulation of multiple signal molecules and signal transduction pathways. After abnormal regulation of these molecules in the basal cells of the esophagus occurs, multiple diseases, including esophageal atresia with or without tracheoesophageal fistula, Barrett esophagus, gastroesophageal reflux, and eosinophilic esophagitis, will take place as a result. Furthermore, expression changes of signal molecules or signal pathways in basal cells and the microenvironment around basal cells both can initiate the switch of malignant transformation...

Despite remarkable progress in polychemotherapy protocols, pediatric B-cell acute lymphoblastic leukemia (B-ALL) remains fatal in around 20% of cases. Hence, novel targeted therapies are needed for patients with poor prognosis. Glucocorticoids (GCs) are drugs commonly administrated for B-ALL treatment. Activation of the phosphatidylinositol 3-kinase (PI3K)/Akt/mammalian target of rapamycin signaling pathway is frequently observed in B-ALL and contributes to GC-resistance. Here, we analyzed for the first time to our knowledge, the therapeutic potential of pan and isoform-selective PI3K p110 inhibitors, alone or combined with dexamethasone (DEX), in B-ALL leukemia cell lines and patient samples...

Alopecia areata (AA) is a common autoimmune disorder affecting millions of people worldwide, which manifests as a sudden, non-scarring hair loss. The expression of a pro-inflammatory cytokine, interferon-gamma (INF-γ), has been well established to be involved in the development of AA. As IFN-γ and other cytokines are also known to up-regulate programmed cell death ligand 1 and 2 (PD-L1 and PD-L2), which both negatively control immune responses, we asked whether or not a high number of infiltrated T cells, seen in AA lesions, can modulate the expression of PD-L1 and PD-L2 in skin cells...
