[ 1 ] - Protein expression changes of HCN1 and HCN2 in hippocampal subregions of gerbils during the normal aging process

Objective(s): Hyperpolarization-activated cyclic nucleotide-gated (HCN) channels play essential roles in various hippocampal functions, including regulation of long-term potentiation, synaptic plasticity, and hippocampal-dependent cognitive process. The objective of this study was to investigate age-related changes in HCN1 and HCN2 protein expressions in gerbil hippoca...

[ 2 ] - Stronger antioxidant enzyme immunoreactivity of Populus tomentiglandulosa extract than ascorbic acid in rat liver and kidney

Objective(s): Populus species have various pharmacological properties, including antioxidant activity. In this study, the effects of Populus tomentiglandulosa extract (PTE) on histopathology and antioxidant enzymes in the rat liver and kidney were examined.  Materials and Methods: Sprague-Dawley rats were assigned to three groups; (1) no...

[ 3 ] - Change of Nurr1 expression in mouse hippocampal CA3 region following excitotoxic neuronal damage

Objective(s): Nuclear receptor-related protein 1 (Nurr1), one of immediate-early genes, is a member of orphan nuclear receptor family. The aim of this study was to investigate the time-dependent change of Nurr1 protein expression in the mouse hippocampal CA3 region following kainic acid (KA)-induced excitotoxic neuronal damage.Materials and Methods:</...
