Transient High-Glucose Stimulation Induces Persistent Inflammatory Factor Secretion from Rat Glomerular Mesangial Cells via an Epigenetic Mechanism

Abstract: Background/Aims: Diabetic nephropathy is the one of the most serious microvascular complications of diabetes mellitus, and “metabolic memory” plays a vital role in the development of diabetic complications. To investigate the effect of epigenetics on metabolic memory, we analyzed the impact of transient high-glucose stimulation on the secretion of inflammatory factors from rat glomerular mesangial cells. Methods: Rat glomerular mesangial cells (HBZY-1) were divided into three groups: high-glucose group (25 mM … Show more

“…Methylation of lysine and arginine residues also can result in transcriptional activation. For instance, in rats, histone methylation is associated with persistent release of pro-inflammatory cytokines (35). Particularly interesting are the increased transcription of PR/SET domain proteins (PRDMs) encoding for histone methyltransferases.…”

“…TGF-β1 also increases CCL2 and MCP-1 induced protein-1 (MCPIP1), a suppressor of microRNA (miR)-146a via the ErbB4/epidermal growth factor receptor signaling pathway [36]. In glomerular mesangial cells, the up-regulated expression of endothelial vascular cell adhesion protein 1 (VCAM-1) and CCL2 can be sustained for at least 72 h under high glucose conditions [37]. Advanced glycation end products (AGEs) increase the expression of intercellular adhesion molecule 1 (ICAM-1) and CCL2 through the member A Rho kinase (RhoA/ROCK) signaling pathway [38].…”

“…The distribution of m 6 A has tissue specificity, and kidney is one of the most distributed organs of m 6 A [11] . m 6 A is catalyzed by the "writer"-methyltransferase complex (METTL3, METTL14, WTAP) on the consensus motif "RRACH" (R=G/A; H=A/C/U) [12] . On the contrary, the "erasers" -demethylase (ALKBH5 and FTO) can "erase" m 6 A on RNA [12] .…”

"Reader" -modification recognition protein can function through a direct or indirect combination of RNA, making the methylated RNA to be functionalized, including translation, RNA stability, selective editing, RNA processing, nuclear transportation, microRNA binding, and RNA-protein interaction [13] .…”
