Abstract
Context: Persistent hyperglycaemia increases SET7/9 expression and endoplasmic reticulum (ER) stress which causes inflammation, apoptosis, and fibrosis in renal tubular epithelial cells leading to diabetic kidney disease (DKD).
Objective: Current study explores the renoprotective potential of a novel SET7/9 inhibitor, Cyproheptadine, and the underlying molecular mechanisms in hyperglycaemia-induced renal tubular epithelial cell injury.
Methods: Change in expression of SET7/9, histone H3 lysine (K4) monomethylation (H3K4Me1), inflammatory, fibrotic, and ER stress proteins were evaluated in-vivo and in-vitro. NRK-52E cells were used to study the preventive effect of Cyproheptadine against hyperglycaemia-induced ER stress and subsequent inflammation and fibrosis.
Results: SET7/9 and H3K4Me1 expression significantly increased with ER stress, inflammation, apoptosis, and fibrosis, in-vivo and in-vitro under hyperglycaemia. However, the cells treated with Cyproheptadine showed significant suppression of H3K4Me1 and reduction in ER stress, inflammation, apoptosis, and fibrosis.
Conclusion: Cyproheptadine prevented hyperglycaemia-induced renal fibrosis and inflammation by reducing H3K4Me1 expression and ER stress.
期刊介绍:
Archives of Physiology and Biochemistry: The Journal of Metabolic Diseases is an international peer-reviewed journal which has been relaunched to meet the increasing demand for integrated publication on molecular, biochemical and cellular aspects of metabolic diseases, as well as clinical and therapeutic strategies for their treatment. It publishes full-length original articles, rapid papers, reviews and mini-reviews on selected topics. It is the overall goal of the journal to disseminate novel approaches to an improved understanding of major metabolic disorders.
The scope encompasses all topics related to the molecular and cellular pathophysiology of metabolic diseases like obesity, type 2 diabetes and the metabolic syndrome, and their associated complications.
Clinical studies are considered as an integral part of the Journal and should be related to one of the following topics:
-Dysregulation of hormone receptors and signal transduction
-Contribution of gene variants and gene regulatory processes
-Impairment of intermediary metabolism at the cellular level
-Secretion and metabolism of peptides and other factors that mediate cellular crosstalk
-Therapeutic strategies for managing metabolic diseases
Special issues dedicated to topics in the field will be published regularly.
