Trehalose (a-D-glucosyl-[1,1]-a-D-glucopyranoside) is involved in mechanisms that coordinate metabolism with plant growth adaptation and development. The main objective of the current work was to find out whether trehalose feeding affects the expression of two genes involved in photosynthesis: one gene coding for photosystem1 subunit H (PS1-H) and the other for the light harvesting complex B1 (...

Introduction: Maintenance of neurogenesis depends on the function of some histone-modifying enzymes; including Enhancer of zeste homolog 2 (EZH2) and histone acetyltransferases (P300). The mechanism of epigenetic regulation and gene expression underlying the transition of human umbilical cord blood mesenchymal stem cells (hUCB-MSCs) into MNs has not been fully clarified.  Methods: Two morphoge...

Parthenolide is a secondary metabolite, which naturally occurs in the feverfew plant and is responsible for its healing power. The potential of parthenolide in inhibition of cancer cell growth, alone or in combination with other anti-cancer therapeutics, have been studied in several laboratories. In this study, the effect of extracted parthenolide on the expression of seven pro-apoptotic genes,...

Background and Objective: Dysregulation of long-term expression of non-coding RNAs (lncRNAs) has a potential role in progressive brain disorders such as Alzheimer's disease. This study aimed to analyze the apoptosis and expression of 51A and NAT-Rad18 lncRNAs and their target genes in brain tissue and peripheral blood mononuclear cells (PBMCs) of the rat model of AD, before and after memantine ...

background: members of the eukaryotic hsp90 family function as important molecular chaperones in the assembly, folding and activation of cellular signaling in development. two hsp90 genes, hsp90 alpha and hsp90 beta, have been identified in fish and homeothermic vertebrates but not in poikilothermic vertebrates. in the present study, the expression of hsp90 alpha and hsp90 beta genes in xenopus...
