STAT3 mutations have been described in 30-40% of T-large granular lymphocyte (T-LGL) leukemia patients, leading to STAT3 pathway activation. Considering the heterogeneity of the disease and the several immunophenotypes that LGL clone may express, the aim of this work was to evaluate whether STAT3 mutations might be associated with a distinctive LGL immunophenotype and/or might be indicative for specific clinical features.Our series of cases included a pilot cohort of 101 T-LGL leukemia patients (68 CD8+/CD4- and 33 CD4+/CD8±) from Padua Hematology Unit (Italy) and a validation cohort of additional 20 patients from Rennes Hematology Unit (France)...

We investigated the role of the Fas/FasL signalling pathway and inhibin B expression in rats with an experimentally induced left-side varicocele. Forty-five Sprague Dawley (SD) male rats were randomly divided into three groups in average: control group, sham group and experimental group. The expression of inhibin B in the rat left testis was analysed at the mRNA and protein levels by reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting respectively. The expressions of Fas, FasL and caspase-3 in the left testis were measured by RT-PCR and immunofluorescence...

Food protein-induced enterocolitis syndrome (FPIES) is a potentially severe presentation of non-IgE-mediated gastrointestinal food allergy (non-IgE-GI-FA) with heterogeneous clinical manifestations. Acute FPIES is typically characterized by profuse vomiting and lethargy, occurring classically 1-4 hours after ingestion of the offending food. When continuously exposed to the incriminated food, a chronic form has been described with persistent vomiting, diarrhea, and/or failure to thrive. Although affecting mainly infants, FPIES has also been described in adults...

Pogostemonis Herba is a functional food approved in Asian countries. Its major constituent, patchouli alcohol (PA), possesses a gastroprotective effect and is reported to transform into β-patchoulene (β-PAE) under acidic conditions. To investigate whether β-PAE, the metabolite of PA, has a protective effect on the gastrointestinal tract, the formation of β-PAE by gastric juice and the anti-ulcerogenic potential of β-PAE against ethanol-induced gastric injury were evaluated. The Results indicated that PA was converted to β-PAE by rat gastric juice...

Necroptosis is a regulated form of cell death involved in several disease models including in particular liver diseases. Receptor-Interacting Protein Kinases, RIPK1 and RIPK3, are the main serine/threonine kinases driving this cell death pathway. We screened a non-commercial kinase-focused chemical library allowed us to identify Sibiriline as new inhibitor of necroptosis induced by TNF in Fas-Associated protein with Death Domain (FADD)-deficient Jurkat cells. Moreover, Sib inhibits necroptotic cell death induced by various death ligands in human or mouse cells while not protecting from caspase-dependent apoptosis...

Non-alcoholic fatty liver disease (NAFLD) presents with growing prevalence worldwide, though its pharmacological treatment remains to be established. This study aimed to evaluate the effects of a PPAR-alpha agonist on liver tissue structure, ultrastructure, and metabolism, focusing on gene and protein expression of de novo lipogenesis and gluconeogenesis pathways, in diet-induced obese mice. Male C57BL/6 mice (three months old) received a control diet (C, 10% of lipids, n = 10) or a high-fat diet (HFD, 50% of lipids, n = 10) for ten weeks...

Food allergies (FAs) are of increasing public health concern and are characterized by a large spectrum of diseases. Their diversity is well known for immunologic pathways (IgE, non-IgE mediated FAs), and natural history. Many other factors and patient characteristics are involved including type of food, exposure route, allergic comorbidities, gender, racial and ethnic backgrounds, co-factors and health conditions. Food allergen components and sensitization profiles are also involved in FA phenotypes. A new approach to chronic disorders based on the identification of phenotypes through extensive knowledge of all the complex components is also applicable to FAs and could lead towards integrative care management...

Heart failure (HF) is associated with metabolic perturbations, particularly of fatty acids (FA), which remain to be better understood in humans. This study aimed at testing the hypothesis that HF patients with reduced ejection fraction, display systemic perturbations in levels of energy-related metabolites, especially those reflecting dysregulation of FA metabolism, namely acylcarnitines (ACs). Circulating metabolites were assessed using mass spectrometry (MS)-based methods in two cohorts. The main cohort consisted of 72 controls and 68 HF patients, exhibiting depressed left ventricular ejection fraction (25...

We report the neuroprotective role of FAS apoptotic inhibitory molecule 2 (FAIM2), an inhibitor of the FAS signaling pathway, during stress-induced photoreceptor apoptosis. Retinal detachment resulted in increased FAIM2 levels in photoreceptors with higher amounts detected at the tips of outer segments. Activation of FAS death receptor via FAS-ligand led to JNK-mediated FAIM2 phosphorylation, decreased proteasome-mediated degradation and increased association with the FAS receptor. Photoreceptor apoptosis was accelerated in Faim2 knockout mice following experimental retinal detachment...

Tartary buckwheat (Fagopyrum tataricum) has been established globally as a nutritionally important food item, particularly owing to high levels of bioactive compounds such as rutin. This study investigated the effect of tartary buckwheat extracts (TBEs) on adipogenesis and inflammatory response in 3T3-L1 cells. TBEs inhibited lipid accumulation, triglyceride content, and glycerol-3-phosphate dehydrogenase (GPDH) activity during adipocyte differentiation of 3T3 L1 cells. The mRNA levels of genes involved in fatty acid synthesis, such as peroxisome proliferator-activated receptor-γ (PPAR-γ), CCAAT/enhancer binding protein-α (CEBP-α), adipocyte protein 2 (aP2), acetyl-CoA carboxylase (ACC), fatty acid synthase (FAS), and stearoylcoenzyme A desaturase-1 (SCD-1), were suppressed by TBEs...

During the last decades, the study of primary immunodeficiencies (PIDs) has contributed tremendously to unravel novel pathways involved in a variety of immune responses. Many of these PIDs have an autosomal recessive (AR) mode of inheritance. Thus, the investigation of the molecular basis of PIDs is particularly relevant in consanguineous populations from Middle East and North Africa (MENA). Although significant efforts have been made in recent years to develop genetic testing across the MENA region, few comprehensive studies reporting molecular basis of PIDs in these settings are available...

Adipogenesis involves a highly orchestrated series of complex events in which microRNAs (miRNAs) may play an essential role. In this study, we found that the miR-185 expression increased gradually during 3T3-L1 cells differentiation. To explore the role of miR-185 in adipogenesis, miRNA agomirs and antagomirs were used to perform miR-185 overexpression and knockdown, respectively. Overexpression of miR-185 dramatically reduced the mRNA expression of the adipogenic markers, PPARγ, FABP4, FAS, and LPL, and the protein level of PPARγ and FAS...

Liver injury is a common pathological basis of various liver diseases, and long-term liver injury is often an important initiation factor leading to liver fibrosis and even liver cirrhosis and hepatocellular carcinoma (HCC). It has been reported that deproteinized extract of calf blood (DECB) can inhibit the replication of hepatitis B virus and confers a protective effect on the liver after traumatic liver injury. However, few studies on the regulatory factors and mechanisms of DECB have been reported. In this current study, an acute mouse liver injury model was established with carbon tetrachloride (CCl4)...

The aim of the present study was to confirm the role of 11β-hydroxysteroid dehydrogenases type 2(11β-HSD-2) in steroid induced osteonecrosis of the femoral head(SANFH). We cultured mouse bone-like cells (MLO-Y4) and mouse osteoblast-like cells (MC3T3-E1). After overexpressed 11β-HSD-2 successfully, we induced cell apoptosis by dexamethasone (DXM). The level of cell apoptosis, the expression of Bcl-2 in MLO-Y4 cells and the expression of Fas and caspase8 in MC3T3-E1 cells were detected. Then, we constructed 11β-HSD-2 siRNA plasmid and represented it on MLO-Y4/MC3T3-E1 Cells, to down-regulate the 11β-HSD-2 expression...

This study investigated the effects of dietary protein levels on disease resistance, immune function and structural integrity in the head kidney, spleen and skin of grass carp (Ctenopharyngodon idella). A total of 540 grass carp (264.11 ± 0.76 g) were fed six diets containing graded levels of protein (143.1, 176.7, 217.2, 257.5, 292.2 and 322.8 g digestible protein kg(-1) diet) for 8 weeks. After the growth trial, fish were challenged with Aeromonas hydrophila for 14 days. The results indicated that optimal levels of dietary protein: (1) (1) increased the lysozyme (LA) and acid phosphatase (ACP) activities and the complement 3 (C3) and C4 contents, up-regulated antimicrobial peptides, anti-inflammatory cytokines, inhibitor of κBα, target of rapamycin and ribosomal protein S6 kinases 1 mRNA levels, whereas down-regulated pro-inflammatory cytokines, nuclear factor kappa B (NF-κB) P65, IKKβ, IKKγ, eIF4E-binding proteins (4E-BP) 1 and 4E-BP2 mRNA levels in the head kidney, spleen and skin of grass carp (P < 0...

Lipid droplets (LDs) provide an "on-demand" source of fatty acids (FAs) that can be mobilized in response to fluctuations in nutrient abundance. Surprisingly, the amount of LDs increases during prolonged periods of nutrient deprivation. Why cells store FAs in LDs during an energy crisis is unknown. Our data demonstrate that mTORC1-regulated autophagy is necessary and sufficient for starvation-induced LD biogenesis. The ER-resident diacylglycerol acyltransferase 1 (DGAT1) selectively channels autophagy-liberated FAs into new, clustered LDs that are in close proximity to mitochondria and are lipolytically degraded...
