Effect of adiponectin on estradiol and progesterone secretion from human luteinized granulosa cells in vitro
(2021)Ιnformation on the role of adiponectin in human ovarian steroidogenesis is limited. The present study aimed to investigate the effect of different doses of adiponectin on the secretion of estradiol and progesterone by human ... -
Effect of resistin on estradiol and progesterone secretion from human luteinized granulosa cells in culture
(2019)Information on the role of resistin on steroidogenesis is limited to animal studies. The aim of this study was to investigate the effect of various doses of resistin on estradiol and progesterone secretion from human ... -
Effects of ghrelin on activation of Akt1 and ERK1/2 pathways during in vitro maturation of bovine oocytes
(2017)The purpose of this study was to investigate the possible molecular pathways through which ghrelin accelerates in vitro oocyte maturation. Bovine cumulus-oocyte complexes (COCs), after 18 or 24 h maturation in the absence ... -
Efforts to create an artificial testis: Culture systems of male germ cells under biochemical conditions resembling the seminiferous tubular biochemical environment
(2005)Induction of meiotic and post-meiotic alterations of male germ cells in vitro has been the target of several research efforts since 1960. However, to date, the establishment of an ideal culture system in which spermatogonial ... -
Enteroviral infection in Greek AIDS patients
(2004)Objective: Prolonged intestinal replication of polioviruses has not previously been studied in Greek AIDS patients. The objective of our study was to estimate the prevalence of enteroviral infections in this population. ... -
The flavoring and not the nicotine content is a decisive factor for the effects of refill liquids of electronic cigarette on the redox status of endothelial cells
(2020)Electronic cigarettes are constantly gaining ground as they are considered less harmful than conventional cigarettes, and there is also the perception that they may serve as a potential smoking cessation tool. Although the ... -
Growth hormone, insulin-like growth factor I, and leptin interaction in human cultured lutein granulosa cells steroidogenesis
(2008)Objective: To investigate the effect of leptin on the actions of growth hormone (GH) and insulin-like growth factor-I (IGF-I) in ovarian steroidogenesis in vitro. Design: In vitro cell culture study. Setting: Research ... -
Hepatocyte autotaxin expression promotes liver fibrosis and cancer
(2017)Autotaxin (ATX) is a secreted lysophospholipase D that catalyzes the production of lysophosphatidic acid (LPA), a pleiotropic growth-factor–like lysophospholipid. Increased ATX expression has been detected in various chronic ... -
Human mesenchymal stem cells with enhanced telomerase activity acquire resistance against oxidative stress-induced genomic damage
(2017)Background Human mesenchymal stem cells (MSC) are important tools for several cell-based therapies. However, their use in such therapies requires in vitro expansion during which MSCs quickly reach replicative senescence. ... -
Human peripheral blood mononuclear cell culture for flow cytometric analysis of phosphorylated mitogen-activated protein kinases
(2012)Lymphocyte activation and fine tuning of downstream signaling circuits for the regulation of cytokine expression are critical for a successful immune response. Hence, technical protocols permitting simultaneous testing of ... -
Hypoxia-induced collagen crosslinking as a mechanism for enhancing mechanical properties of engineered articular cartilage
(2013)Objective: The focus of tissue engineering of neocartilage has traditionally been on enhancing extracellular matrix and thus biomechanical properties. Emphasis has been placed on the enhancement of collagen type and quantity, ... -
IDO decreases glycolysis and glutaminolysis by activating GCN2K, while it increases fatty acid oxidation by activating AhR, thus preserving CD4+ T-cell survival and proliferation
(2018)It is generally hypothesized in the literature that indoleamine 2,3-dioxygenase (IDO), by degrading L-tryptophan along the kynurenine pathway, suppresses CD4+ T-cell function by inducing apoptosis, inhibiting proliferation ... -
In human alloreactive CD4+ T-cells, dichloroacetate inhibits aerobic glycolysis, induces apoptosis and favors differentiation towards the regulatory T-cell subset instead of effector T-cell subsets
(2016)Although kidney transplantation is the best therapy for end-stage renal disease, rejection remains a concern, and currently available immunosuppressive agents contribute to morbidity and mortality. Thus, novel immunosuppressive ... -
In human cell cultures, everolimus is inferior to tacrolimus in inhibiting cellular alloimmunity, but equally effective as regards humoral alloimmunity
(2017)Purpose: Acute cellular rejection is the major cause of immune-mediated graft failure early in the course of kidney transplantation, whereas chronic antibody-mediated rejection is a major contributor to graft loss in the ... -
In Mixed Lymphocyte Reaction, the Hypoxia-Inducible Factor Prolyl-Hydroxylase Inhibitor Roxadustat Suppresses Cellular and Humoral Alloimmunity
(2020)Hypoxia-inducible factor (HIF) prolyl-hydroxylase inhibitors are currently used for the treatment of renal anemia. Since HIF affects immune cells, we evaluated the effect of such a drug, the roxadustat, on adaptive immunity. ... -
Increase in antioxidant activity by sheep/goat whey protein through nuclear factor-like 2 (Nrf2) is cell type dependent
(2016)The aim of the present study was to investigate the molecular mechanisms through which sheep/goat whey protein exerts its antioxidant activity. Thus, it was examined whey protein's effects on the expression of transcription ... -
Indoleamine 2, 3-dioxygenase Up-regulates Hypoxia-inducible Factor-1α Expression by degrading l-Tryptophan but not its activity in human alloreactive t-cells
(2018)Indoleamine 2, 3-dioxygenase (IDO) suppresses T-cell function at least in part by altering cell metabolism. Hypoxia-inducible factor-1 (HIF-1) increases upon T-cell activation and alters cell metabolism favoring their ... -
Indoleamine 2,3-dioxygenase, by degrading L-tryptophan, enhances carnitine palmitoyltransferase i activity and fatty acid oxidation, and exerts fatty acid-dependent effects in human alloreactive CD4+ T-cells
(2016)Indoleamine 2,3-dioxygenase (IDO) is expressed in antigen presenting cells and by degrading L-tryptophan along the kynurenine pathway suppresses CD4+ T-cell proliferation, induces apoptosis and promotes differentiation ... -
