Phosphoglucose isomerase/autocrine motility factor (PGI/AMF) is secreted by tumors and influences tumor growth and metastasis. In order to investigate the effects of silencing PGI/AMF on the migration and the sphere forming abilities of human glioblastoma U87 cells, as well as on the side population cells (SPCs), PGI/AMF was silenced using siRNA. Western blot analysis and RT-qPCR were used to a...

To clarify the role of the PGI(2)/PGI(2) receptor (IP) system in rabbit cortical collecting duct (RCCD), we characterized the expression of IP receptors in the rabbit kidney. We show by Northern and Western blotting that IP mRNA and protein was detectable in all three regions of the kidney. To determine how PGI(2) signals, we compared the effects of different PGI(2) analogs [iloprost (ILP), car...

Introduction: In this study the effect of Matricaria recutita extract on acute pain in the presence and absence of flumazenil (antagonist of benzodiazepine) and lesioned paragigantocellularis (PGi) nucleus was investigated. Method: Wistar male rats (250±20 g) were used. Animals were grouped randomly into intact, sham and bilateral lesion of PGi nucleus. Intact and lesioned animals, each...

In this study the effect of adenosine and caffeine on spontaneous activity of paragigantocellularis (PGi) neurons was investigated. The spontaneous activity of PGi neurons was significantly decreased by microinjection of adenosine (10 nM, 0.5 µl) into PGi nucleus of both control and morphine-dependent rats. The decrease in firing rate of PGi neurons of morphine-dependent rats was greater than t...

AIM To evaluate the Immunomodulatory effects of CagA expression; pepsinogen I, II & gastrin-17 on PMNs and lymphocytes Fas expression in inflammatory and gastric cells; demographic distribution of Fas molecule in gastric tissue and inflammatory cells. METHODS Gastroduodenal biopsies were taken from 80 patients for histopathology and H. pylori diagnosis. Serum samples were used for evaluation ...

In lowland Cobs butterflies, genotypes of the enzyme phosphoglucose isomerase (PGI) show major differences in molecular function, from which genotypic differences in organismal performance and fitness components in the wild are accurately predictable. The alpine species Colias meadii seems to share electromorph alleles with lowland congeners at PGI and phosphoglucomutase (PGM). However, high-re...

Phosphoglucose isomerase (PGI; EC 5.3.1.9) is a cytosolic housekeeping enzyme of the sugar metabolism pathways that plays a key role in both glycolysis and gluconeogenesis. PGI is a multifunctional dimeric protein that extracellularly acts as a cytokine with properties that include autocrine motility factor (AMF)-eliciting mitogenic, motogenic, and differentiation functions, and PGI has been im...
