Gastrokine mRNA expression in gastric tissue from dogs with helicobacter colonisation but without inflammatory change during treatment

Abstract

Gastrokines (GKNs) are bioactive substances secreted by gastric cells. Evidence supports functional roles for GKNs in gastric homeostasis, immune responses and tumour suppression. Down-regulation has been reported in Helicobacter pylori associated gastritis and other inflammatory gastrointestinal conditions in mice and people. The aim of this study was to evaluate GKN gene expression in dogs positive for other Helicobacter spp. both before and after treatment. Expression of Gkn-1 and Gkn-2 mRNA was studied in endoscopic biopsy samples collected from seven healthy dogs over three time-points pre- (T0) and at 1 and 18 weeks post-treatment for Helicobacter spp. colonisation (T1 & T2). The relat..
