Introduction: Genetic factors including the level of expression of the fingerprint of genes involved in the development of bones and cartilage such as GDF-5 or ESR-α or CALM-1 are known to be strong determinants of the osteoarthritis (OA) in Caucasian and Oriental populations. Because of high prevalence of OA in Indian population and availability of limited genetic data, we determined whether similar genetic factors are involved in Indians as well. Methods: A case control study was carried out involving 500 patients of knee OA and equal number of healthy controls...

The current study aimed to investigate whether the increased expression of long chain acyl-coenzymeA synthetase 1 (ACSL1) in peripheral blood leukocytes (PBL) may be a molecular marker for the genetic evaluation of acute myocardial infarction (AMI). The mechanism of action of ACSL1 in the pathogenesis of AMI was also investigated. A total of 75 patients with AMI and 70 individuals without coronary heart disease were selected to participate in the present study. The demographic and clinical information of the enrolled subjects was recorded...

Adipose-derived mesenchymal stem cells (ASCs) are known to have immunomodulatory properties through soluble factors or by direct cell-to-cell contact. This study aimed to assess the expression of HLA-G and IDO activity in breast cancer and normal ASCs and to see if ASC is capable of modulating both tumor cells and immune system cells in vitro. ASCs were enzymatically isolated from 15 breast cancer patients and 10 normal individuals. Then they were cultured, and the impact of their conditioned media on the movement of the MDA-MB-231 breast cancer cell line was studied in wound healing scratch assay...

OBJECTIVES: Type 2 Diabetes Mellitus (T2DM), which often accompanies dyslipidemia, is considered an inflammatory disease. GPR109A, as a niacin receptor, is up-regulated under high glucose concentration. Activation of GPR109A reduces GSIS and exerts anti-inflammatory effects by regulating NF-κB/IL-1β signaling. Metformin improves hyperglycemia, increases insulin sensitivity and attenuates the activation of the NF-κB pathway in T2DM. We aimed to examine whether metformin plays beneficial effects in T2DM by regulating the GPR109A signaling...

Myasthenia gravis (MG) is an autoimmune disease caused by sensitization of the immune system to self-antigens. We have previously shown that targeting MG-susceptible alleles can significantly inhibit proliferation of disease-specific T cells. In this work, we humanized a murine monoclonal antibody (mAb) LG11, capable of blocking MG-associated DQ beta 1 (DQB1) allele and reformatted it into single-chain fragment variable (scFv). A fully functional humanized scFv was obtained by optimizing variable domain orientations and linker lengths, along with the optimization of expression conditions and codons to suit Escherichia coli expression machinery...

Primary bone lymphomas (PBLs) are composed of malignant lymphoid cells presenting in osseous sites, without supra-regional lymph node or extranodal involvement. We systematically characterized the immunophenotype and the myeloid differentiation factor 88 (MYD88)-L265P gene mutation status in PBL. Clinical data from 19 patients with PBL treated at Nanjing Drum Tower Hospital between 2009 and 2015 were analyzed retrospectively. Protein expression patterns were identified immunohistochemically, and MYD88 mutation was assessed using polymerase chain reaction and direct DNA sequencing...

Interleukin (IL-) 23, a member of IL-12 family, is a composite cytokine with the subunits of p19 and p40. Although IL-12 and IL-23 share the p40 subunit, they play vastly different roles in immune regulation. In teleost, much emphasis has been placed on the identification of IL-12, but evidence for the existence of IL-23 is still lacking. In the present study, a p19 gene and three p40 paralogues were isolated and identified from grass carp, suggesting multiple assembly of IL-23 molecules in fish species. To address this issue, the existence of different p19/p40 heterodimers were examined by Co-Immunoprecipitation (Co-IP) assay, showing that only co-expression of p19 and each p40 subunit could produce the soluble proteins corresponding to three IL-23 isoforms...

The NLRC3-like (NLRC3L) molecule from the goldfish transcriptome database was identified and characterized. Quantitative gene expression analysis revealed the highest mRNA levels of NLRC3L were in the spleen and intestine, with lower mRNA levels observed in muscle and liver. Goldfish NLRC3L was differentially expressed in goldfish immune cell populations with highest mRNA levels measured in PBLs and macrophages. We generated a recombinant form of the molecule (rgfNLRC3L) and an anti-CT-NLRC3L IgG. Treatment of goldfish primary kidney macrophages in vitro with ATP, LPS and heat-killed Aeromonas salmonicida up-regulated the NLRC3L mRNA and protein...

INTRODUCTION: Recently, there has been increasing interest in the preoperative prediction and prevention of post-hepatectomy liver failure (PHLF). This is a particular concern in colorectal liver metastases (CRLM), when surgery follows potentially hepatotoxic chemotherapy. Platelet-based liver scores (PBLS) such as APRI and FIB-4 are predictive of chemotherapy-associated liver injury (CALI) and PHLF. Estimation of the future liver remnant function (eFLRF) by combining (99m)Tc-Mebrofenin Hepatobiliary Scintigraphy (HBS(BSA)) with future liver remnant volume ratio (FLRV%), is predictive of PHLF and related mortality...

Cadmium (Cd) is a known environmental pollutant that is associated with inflammation, oxidative stress, and cell apoptosis. Astragalus polysaccharide (APS) is a major component of Astragalus membranaceus, a vital qi-reinforcing herb medicine with favorable immuneregulation properties. To study the effect of APS on the inhibition of the cadmium-induced injury of peripheral blood lymphocytes (PBLs) in chickens through the MDA5/NF-κB signaling pathway, PLBs acquired from 15-day-old chickens were divided into control group, Cd group, APS + Cd group, anti-MDA5 mAb + Cd group, BAY 11-7082 (a nuclear factor kappa-light chain-enhancer of activated B cells [NF-κB] inhibitor) +Cd group, APS group, anti-MDA5 mAb group, and BAY 11-7082 group...

Cytostatic antineoplastic drugs are considered carcinogenic and mutagenic risk factors for health workers who are occupationally exposed to them; however, the molecular mechanisms underlying these effects remain to be elucidated. Therefore, the present study aimed to investigate the underlying mechanisms of antineoplastic drugs‑induced apoptosis of peripheral blood lymphocytes (PBLs) obtained from oncology nurses handling antineoplastic drugs. A microRNA (miRNA/miR) polymerase chain reaction (PCR) array was performed to analyze the expression levels of miRNAs in the PBLs from 3 trained nurses occupationally exposed to antineoplastic drugs...

INTRODUCTION: Alloreactive tumor specific T cells are important arsenals of the adaptive immune system in the fight against tumors. However, stem cell-like memory T cells (Tscm) provide the key to effective elimination of tumor cells. Methods for generating these T cell subsets already exist. However, they could be made more efficient. Further, they are expensive and unattainable to the resource poor laboratories. In this regard, we are hereby describing a novel in vitro allogeneic co-culture method for raising allo-restricted tumor specific Tscm cells that we developed...

Background: Dietary fish oils, rich in long-chain n-3 (ω-3) fatty acids (FAs) [e.g., docosahexaenoic acid (DHA, 22:6n-3) and eicosapentaenoic acid (EPA, 20:5n-3)], modulate inflammatory reactions through various mechanisms, including gene expression, which is measured as messenger RNA concentration. However, the effects of long-term treatment of humans with DHA and EPA on various epigenetic factors-such as DNA methylation, which controls messenger RNA generation-are poorly described.Objective: We wanted to determine the effects of 6 mo of dietary supplementation with an n-3 FA preparation rich in DHA on global DNA methylation of peripheral blood leukocytes (PBLs) and the relation to plasma EPA and DHA concentrations in Alzheimer disease (AD) patients...

Dual-specificity MAP kinase (MAPK) phosphatases (DUSPs) are well-established negative modulators in regulating MAPK signaling in mammalian cells and tissues. Our previous studies have shown the involvement of DUSP6 in regulating innate immunity in Japanese flounder Paralichthys olivaceus. In order to gain a better understanding of the role of DUSPs in fish innate immunity, in the present study we identified and characterized three additional DUSP genes including DUSP1, 2 and 5 in P. olivaceus. The three Japanese flounder DUSP proteins share common domain structures composed of a conserved N-terminal Rhodanase/CDC25 domain and a C-terminal catalytic phosphatase domain, while they show only less than 26% sequence identities, indicating that they may have different substrate selectivity...

INTRODUCTION: The prevalence of type 2 diabetes (T2D) and the metabolic syndrome (MetS) is increasing and several studies suggested an involvement of DNA methylation in the development of these metabolic diseases. This study was designed to investigate if differential DNA methylation in blood can function as a biomarker for T2D and/or MetS. METHODS: Pyrosequencing analyses were performed for the candidate genes KCNJ11, PPARγ, PDK4, KCNQ1, SCD1, PDX1, FTO and PEG3 in peripheral blood leukocytes (PBLs) from 25 patients diagnosed with only T2D, 9 patients diagnosed with T2D and MetS and 11 control subjects without any metabolic disorders...

Both systemic and locally released steroid hormones, such as cortisol and estrogens, show immunomodulatory actions. This research gives evidence that circulating and leukocyte-derived estrogens can be involved in the regulation of the immune response in common carp, during homeostasis and upon restraining stress. It was found that stress reduced level of blood 17β-estradiol (E2) and down-regulated the gene expression of components of the "classical" estrogen system: the nuclear estrogen receptors and the aromatase CYP19, in the hypothalamus, the pituitary and in the ovaries...

Receptor Expressed in Lymphoid Tissues (RELT) is a human Tumor Necrosis Factor Receptor (TNFR) family member that has two identified homologous binding partners, RELL1 and RELL2. This study sought to further understand the pattern of RELT expression, the functional role of RELT family members, and the mechanism of RELT-induced apoptosis. RELT protein expression was detected in the spleen, lymph node, brain, breast and peripheral blood leukocytes (PBLs). A smaller than expected size of RELT was observed in PBLs, suggesting a proteolytically cleaved form of RELT...

Caspase1 is a member of inflammatory Caspases that play important roles in the innate immune system. Although several teleost caspase1 genes have been identified, their partner proteins and implication in extracellular ATP-mediated immune signaling in fish are still very limited. Here we identified and characterized a caspase1 gene, named JfCaspase1, from Japanese flounder Paralichthys olivaceus. JfCaspase1 mRNA was constitutively expressed in all examined normal tissues with high expression in skin and gills and moderate expression in the enriched Japanese flounder head kidney macrophages (HKMs) and peripheral blood leukocytes (PBLs)...
