Correlations Between Plasma Sphingosine-1-phosphate (S1P) and Gene Expression of S1P Receptors with Mogenic Regulatory Factors Following Resistance Training
Background: The purpose of present study was to investigate whether Sphingosine 1-phosphate (S1P) levels and its receptors gene expressions are correlated with MyoD and myogenin following resistance training. Materials and Methods: 24 eight-week-old male Wistar rats (190-250 gr) were assigned randomly to a control (N = 12) or training (N = 12) group. Rats climbed a resistance training ladder...
متن کاملPlasma paraoxonase, sphingosine-1-phosphate, total sialic acid, and heat shock protein-27 in the liver of the sheep naturally infected with Cysticercus tenuicollis: Evidence on pathological changes
The present study aimed to investigate whether sphingosine 1 phosphate (S1P), paraoxonase (PON), total sialic acid (TSA), and heat shock protein-27 (HSP27) are altered in the sheep during infection of the liver with Cysticercus tenuicollis. This study was conducted on40 healthy sheep and40 sheep with Cysticercus tenuicollis infection. The infected and non-infected animals were selected based on...
متن کاملRole of sphingosine 1-phosphate signaling for the pathogenesis of autoimmune diseases
Sphingosine 1-phosphate (S1P) acts as an extracellular mediator by binding to G protein-coupled receptors, regulating cell proliferation, angiogenesis and inflammation. FTY720 (FTY) is a high-affinity agonist for S1P receptors, inducing internalization of receptors, rendering the cells unresponsive to S1P. Here, we review the role of S1P signaling for the pathogenesis of autoimmune diseases and...
متن کاملSphingosine 1-phosphate interacts with Survivin pathway to enhance tumorigenesis in cancer cells
Objective(s):Degradation of sphingosine 1-phosphate (S1P), as a bioactive lipid, or deregulation of its production involves in tumor progression, metastasis and chemoresistance. Since the tumor progression effects of S1P and its mechanism in chronic lymphoblastic leukemia and non-small cell lung cancer is not fully understood, we investigated the role and one of the mechanisms of S1P in tumor p...
متن کاملمروری بر فینگولیمد؛ اولین داروی خوراکی برای مالتیپلاسکلروزیس
Multiple sclerosis (MS) is a progressive neurological autoimmune disease that usually starts in the late third and early forth decades of life. Demyelination of neurons in the central nervous system (CNS) and, subsequently, loss of nerve cells is the known disease pathogenesis. The disease is controlled by a class of medicines which are mainly immunomodulators. Fingolimod (FIN) is...
