Sepsis, a systemic inflammatory response syndrome (SIRS) caused by infection, is a major public health concern with limited therapeutic options. Infection disturbs the homeostasis of host, resulting in excessive inflammation and immune suppression. This has prompted the clinical use of immunomodulators to balance host response as an alternative therapeutic strategy. Read More

Prostaglandin D stimulates phenotypic changes in vascular smooth muscle cells.

Exp Mol Med 2019 11 18;51(11):1-10. Epub 2019 Nov 18.

Gene and Cell Therapy Center for Vessel-Associated Disease, Medical Research Institute, and Department of Pharmacology, Pusan National University School of Medicine, Gyungnam, 50612, Republic of Korea.

Since chronic inflammation is associated with the pathogenesis of atherosclerosis, inflammatory cytokines might contribute to the phenotypic modulation of vascular smooth muscle cells (VSMCs). Tumor necrosis factor α (TNFα) facilitated the transformation of contractile VSMCs to the synthetic phenotype, as determined by the expression of marker proteins and a collagen gel contraction assay. Western blot analysis and a cyclooxygenase-2 (COX2) promoter assay revealed that TNFα stimulation resulted in the induction of COX2. Read More

Altered Lipid Metabolism in Blood Mononuclear Cells of Psoriatic Patients Indicates Differential Changes in Psoriasis Vulgaris and Psoriatic Arthritis.

Int J Mol Sci 2019 Aug 30;20(17). Epub 2019 Aug 30.

Department of Analytical Chemistry, Medical University of Bialystok, 15-089 Białystok, Poland.

The aim of this study was to investigate possible stress-associated disturbances in lipid metabolism in mononuclear cells, mainly lymphocytes of patients with psoriasis vulgaris (Ps, n = 32) or with psoriatic arthritis (PsA, n = 16) in respect to the healthy volunteers (n = 16). The results showed disturbances in lipid metabolism of psoriatic patients reflected by different phospholipid profiles. The levels of non-enzymatic lipid metabolites associated with oxidative stress 8-isoprostaglandin F2α (8-isoPGF2α) and free 4-hydroxynonenal (4-HNE) were higher in PsA, although levels of 4-HNE-His adducts were higher in Ps.

15-Deoxy-Δ-prostaglandin J2 promotes phosphorylation of eukaryotic initiation factor 2α and activates the integrated stress response.

Stress granules (SGs) are cytoplasmic RNA-protein aggregates formed in response to inhibition of translation initiation. SGs contribute to the stress response and are implicated in a variety of diseases, including cancer and some forms of neurodegeneration. Neurodegenerative diseases often involve chronic phosphorylation of eukaryotic initiation factor 2α (eIF2α), with deletions of eIF2α kinases or treatment with eIF2α kinase inhibitors being protective in some animal models of disease.

Peroxisome proliferator-activated receptor γ (PPARγ) belongs to the nuclear receptor superfamily of PPARs (PPARα, PPARβ/δ, PPARγ). Numerous studies have concentrated on the key role of PPARs in inflammation and a variety of cancers which include prostate, breast, glioblastoma, neuroblastoma, pancreatic, hepatic, leukemia, and bladder and thyroid tumors. This review, specifically deals with anti-tumor and tumorigenicity effects of PPARγ and its natural and synthetic agonists including Troglitazone, Cladosporol A, B, 15-Deoxi-Δ-Prostaglondin J2 (15-d-PGJ2), Ciglitazon, docosahexaenoic acid, eicosapentaenoic acid Alpha-eleostreac acid, Amorfrutin C, Sphingosine 1-phosphate, Evodiamine, Excavatolide B vs respected antagonists as GW9662, bisphenol-A-diglycidyl-ether.

Ligands of the peroxisome proliferator-activated receptor γ inhibit hepatoce llular carcinoma cell proliferation.

Oncol Lett 2017 Oct 8;14(4):4767-4771. Epub 2017 Aug 8.

Department of Hepatobiliary and Pancreatic Surgery, The First Hospital of Jilin University, Changchun, Jilin 130021, P.R. China.

This study was designed to investigate the regulatory role of the peroxisome proliferator-activated receptor γ (PPARγ) in the growth of hepatocellular carcinoma cells under the hypothesis that the levels of the phosphatase and tensin homologue deleted on chromosome 10 (PTEN) mRNA and the phosphorylated Akt (pAkt) protein would be affected by the presence of different receptor ligand concentrations. SMMC-7721 hepatocellular carcinoma cells were cultured in the presence of different concentrations of either 15-deoxyprostaglandin J2 (15-d-PGJ2) or pioglitazone and experiments were conducted in order to determine cell growth changes and measure levels of PTEN mRNA and pAkt protein. Our results after treatment with MTT showed the addition of ligands to the cultured cells inhibited their proliferation in a time- and dose-dependent manner. Read More

PPARγ agonists regulate tobacco smoke-induced Toll like receptor 4 expression in alveolar macrophages.

Respir Res 2014 Mar 11;15:28. Epub 2014 Mar 11.

Institute of Respiratory Disease, The First Affiliated Hospital of China Medical University, Shen Yang City, China.

Background: Peroxisome proliferator-activated receptor-gamma (PPARγ) is a ligand-activated transcription factor that exerts multiple biological effects. Growing evidence suggests that PPARγ plays an important role in inflammation; however, the effects of this transcription factor on the inflammation caused by smoking are unclear.

Methods: We measured the expression of inflammatory cytokines (leukotriene B4, LTB4 and interleukin 8, IL-8), PPARγ and toll-like receptors (TLR2 and TLR4) in alveolar macrophages (AMs) harvested from rats exposed to cigarette smoke (CS) for 3 months in vivo. Read More

Inhibition of adhesive interaction between multiple myeloma and bone marrow stromal cells by PPARgamma cross talk with NF-kappaB and C/EBP.

Blood 2007 Dec 4;110(13):4373-84. Epub 2007 Sep 4.

Basic Research Program, SAIC-Frederick, Frederick, MD, USA.

Binding of multiple myeloma (MM) cells to bone marrow stromal cells (BMSCs) triggers expression of adhesive molecules and secretion of interleukin-6 (IL-6), promoting MM cell growth, survival, drug resistance, and migration, which highlights the possibility of developing and validating novel anti-MM therapeutic strategies targeting MM cells-host BMSC interactions and their sequelae. Recently, we have found that expression of the peroxisome proliferator-activated receptor gamma (PPARgamma) and its ligands can potently inhibit IL-6-regulated MM cell growth. Here we demonstrate that PPARgamma agonists 15-d-PGJ2 and troglitazone significantly suppress cell-cell adhesive events, including expression of adhesion molecules and IL-6 secretion from BMSCs triggered by adhesion of MM cells, as well as overcome drug resistance by a PPARgamma-dependent mechanism.

Hepatic ischemia-reperfusion induces renal heme oxygenase-1 via NF-E2-related factor 2 in rats and mice.

Mol Pharmacol 2007 Mar 6;71(3):817-25. Epub 2006 Dec 6.

Department of Pharmacology, Toxicology and Therapeutics, University of Kansas Medical Center, 3901 Rainbow Boulevard, Kansas City, KS 66160-7417, USA.

Hepatic ischemia-reperfusion (IR) results in Kupffer cell activation and subsequent tumor necrosis factor (TNF) alpha release, leading to localized hepatic injury and remote organ dysfunction. Heme oxygenase (HO)-1 is an enzyme that is induced by various stimuli, including proinflammatory cytokines, and exerts antioxidative and anti-inflammatory functions. Up-regulation of HO-1 is known to protect against hepatic IR injury, but the effects of hepatic IR on the kidney are poorly understood. Read More

Consultant, 2 rue sur les Murs, 17000 La Rochelle.

PPARg (peroxisome proliferator-activated receptor gamma) is a nuclear receptor that regulates the transcription of numerous genes involved in the differentiation, proliferation and apoptosis of various cell types. It was initially discovered in adipocytes as a differentiation agent, then was characterized in vascular endothelium and recently in choroidal and retinal endothelial cells. Agonists that bind to PPARgamma and stimulate its transcriptional activity are endogenous lipids such as lysophosphatidic acid and 15-d-PGJ2 as well as the synthetic pharmacological compounds, thiazolidinediones, used for treating type 2 diabetes.

Biochem Biophys Res Commun 2004 Oct;323(2):402-8

Department of Cardiovascular Medicine, Kyushu University Graduate School of Medical Sciences, Japan.

Proliferation of vascular smooth muscle cells (VSMCs) is induced by various mitogens through activation of extracellular signal-regulated protein kinase (ERK) pathway. We recently reported that peroxisome proliferator-activated receptor (PPAR)gamma activators such as 15-deoxy-Delta12,14-prostaglandin J2 (15-d-PGJ2) and thiazolidinediones (TZDs) activated MEK/ERK pathway through phosphatidylinositol 3-kinase (PI3-K) and induced proliferation of VSMCs. However, the precise mechanisms of PPARgamma activators-induced activation of PI3-K/ERK pathway have not been determined. Read More
