SGLT2 inhibitor canagliflozin alleviates vascular calcification through suppression of NLRP3 inflammasome
CONCLUSIONS: Our study for the first time demonstrates that CANA exerts a protective effect on vascular calcification at least partially via suppressing NLRP3 signaling pathway. Therefore, supplementation of CANA as well as inhibition of NLRP3 inflammasome presents a potential therapy for vascular calcification.PMID:37523743 | DOI:10.1093/cvr/cvad119

Semaphorin 7a regulates inflammatory mediators and permeability in retinal endothelial cells
In this study, we hypothesized that semaphorin 7a (Sema7a) was involved in the increased inflammatory mediators and permeability changes in retinal endothelial cells (REC) grown in high glucose. For these studies, we used diabetic mouse samples and REC to investigate our hypothesis. Primary retinal endothelial cells were grown in normal (5 mM) or high glucose (25 mM glucose) for measurements. In a subset of cells grown in high glucose, cells were transfected with Sema7a siRNA or scrambled siRNA. We measured levels of key inflammatory mediators and zonula occludens-1 (ZO-1) and occludin levels by Western blot. Data suggest ...

STING deletion alleviates podocyte injury through suppressing inflammation by targeting NLRP3 in diabetic kidney disease
This study evaluated the potential role of STING in high glucose (HG)-induced podocyte inflammation response. STING expression was significantly increased in db/db mice, STZ-treated diabetic mice, and HG-treated podocytes. Podocyte-specific deletion of STING alleviated podocyte injury, renal dysfunction, and inflammation in STZ-induced diabetic mice. STING inhibitor (H151) administration ameliorated inflammation and improved renal function in db/db mice. STING deletion in podocytes attenuated the activation of the NLRP3 inflammasome and podocyte pyroptosis in STZ-induced diabetic mice. In vitro, modulated STING expression ...

Tanshinone IIA ameliorates experimental diabetic cardiomyopathy by inhibiting endoplasmic reticulum stress in cardiomyocytes via SIRT1
Phytother Res. 2023 May 1. doi: 10.1002/ptr.7831. Online ahead of print.ABSTRACTDiabetic cardiomyopathy (DCM) is a common complication in patients with diabetes, and ultimately leads to heart failure. Endoplasmic reticulum stress (ERS) induced by abnormal glycolipid metabolism is a critical factor that affects the occurrence and development of DCM. Additionally, the upregulation/activation of silent information regulation 2 homolog-1 (SIRT1) has been shown to protect against DCM. Tanshinone II A (Tan IIA), the main active component of Salviae miltiorrhizae radix et rhizome (a valuable Chinese medicine), has protective effe...

20-Hydroxyecdysone inhibits inflammation via SIRT6-mediated NF- κB signaling in endothelial cells
In conclusion, the present study demonstrates that 20E exerts its effect through SIRT6-mediated deacetylation of NF-κB p65 (K310) to inhibit CD40 expression in ECs, and 20E may have therapeutic potential for the treatment of cardiovascular diseases.PMID:36958525 | DOI:10.1016/j.bbamcr.2023.119460

mir-98-5p regulates gluconeogenesis and lipogenesis by targeting PPP1R15B in hepatocytes
J Cell Commun Signal. 2023 Mar 14. doi: 10.1007/s12079-023-00735-0. Online ahead of print.ABSTRACTSeveral reports suggest that circulatory miRNAs are deregulated in diverse diseases and used as markers for disease diagnosis and prognosis. Here we show that miR-98-5p, that is down-regulated in the circulation during diabetes, regulates hepatic gluconeogenesis and lipogenesis by targeting PPP1R15B. miR-98-5p overexpression significantly decreased the transcript and protein levels of PPP1R15B in hepatic HepG2 cells and increased p-eIF2α expression and these were prevented in the presence of its inhibitor. Two major hepatic h...

Lipid Nanoparticles for Nucleic Acid Delivery to Endothelial Cells
Pharm Res. 2023 Feb 3. doi: 10.1007/s11095-023-03471-7. Online ahead of print.ABSTRACTEndothelial cells play critical roles in circulatory homeostasis and are also the gateway to the major organs of the body. Dysfunction, injury, and gene expression profiles of these cells can cause, or are caused by, prevalent chronic diseases such as diabetes, cardiovascular disease, and cancer. Modulation of gene expression within endothelial cells could therefore be therapeutically strategic in treating longstanding disease challenges. Lipid nanoparticles (LNP) have emerged as potent, scalable, and tunable carrier systems for deliverin...

Inhibition of diabetes-induced Drp1 deSUMOylation prevents retinal vascular lesions associated with diabetic retinopathy
Exp Eye Res. 2022 Nov 23:109334. doi: 10.1016/j.exer.2022.109334. Online ahead of print.ABSTRACTRetinal microvascular endothelial cell (RMEC) injury plays an important role in the pathophysiology diabetic retinopathy (DR). The GTPase dynamin-related protein 1 (Drp1), crucial to mitochondrial dynamics, has been implicated in hyperglycaemia-induced microvascular damage. Moreover, Drp1 can be deSUMOylated by the enzyme sentrin/SUMO-specific protease 3 (SENP3). Whether SENP3/deSUMOylated Drp1 can aggravate DR is unclear. Therefore, we designed this experiment to investigate the role of SENP3/desumoylated Drp1 in DR in vitro an...

CONCLUSIONS: Dnmt3a silencing rescues the negative effects of DOP on ASCs and provides a possible approach for bone tissue regeneration in patients with diabetic osteoporosis.PMID:35927735 | DOI:10.1186/s13287-022-03088-4

ZnT8 Exerts Anti-apoptosis of Kidney Tubular Epithelial Cell in Diabetic Kidney Disease Through TNFAIP3-NF- κB Signal Pathways
Biol Trace Elem Res. 2022 Jul 23. doi: 10.1007/s12011-022-03361-w. Online ahead of print.ABSTRACTApoptosis of kidney tubular epithelial cells contributes to diabetic kidney disease (DKD) pathophysiology, but the mechanisms are not fully understood. Zinc transporter protein member 8 (ZnT8, SLC30A8) is a susceptive gene in diabetes. Here, we aim to investigate whether ZnT8 has effects on pathophysiology of DKD. The animal groups include control, ZnT8KO mice, STZ-induced, and ZnT8-KO-STZ. STZ-induced DKD was performed in male C57BL/6 J mice and in ZnT8-KO mice. High glucose (HG)-induced apoptosis in a normal rat kidney tubula...

Expression and activation of the ketone body receptor HCAR2/GPR109A promotes preservation of retinal endothelial cell barrier function
Exp Eye Res. 2022 May 29:109129. doi: 10.1016/j.exer.2022.109129. Online ahead of print.ABSTRACTPreservation of retinal barrier function is critical to maintenance of retinal health. Therefore, it is not surprising that loss of barrier integrity is a pathologic feature common to degenerative retinal diseases such as diabetic retinopathy. Our prior studies demonstrate the importance of hydroxycarboxylic acid receptor 2/GPR109A (HCAR2/GPR109A) expression in the retinal pigment epithelium (RPE) to outer retinal barrier integrity. However, whether HCAR2/GPR109A is expressed in retinal endothelial cells and has a similar relati...

Inflammatory gene silencing in activated monocytes by a cholesterol tagged-miRNA/siRNA: a novel approach to ameliorate diabetes induced inflammation
Cell Tissue Res. 2022 May 23. doi: 10.1007/s00441-022-03637-6. Online ahead of print.ABSTRACTThere is a major unmet need for the development of effective therapies for diabetes induced inflammation. Increased adenosine-uridine rich elements (AREs) containing mRNAs of inflammatory molecules are reported in inflamed monocytes. Destabilizing these inflammatory mRNAs by the miR-16 could reduce inflammation. DNA microarrays and in vitro cell studies showed that exogenous miR16 and its mimic treatment, in LPS/PMA induced monocytes, significantly downregulated several ARE containing inflammatory cytokine mRNAs similar to those se...
