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...

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...

Agonism of GPR120 Prevented High Glucose-Induced Apoptosis of Retinal Endothelial Cells through Inhibiting NLRP3 Inflammasome
CONCLUSIONS: Activation of GPR120 protects retinal vascular endothelial cells from HG through inhibiting NLRP3 inflammasome. Thus, GPR120 might be a potential therapeutic target to reduce retinal endothelial damage in diabetic retinopathy.PMID:35584771 | DOI:10.1055/a-1811-7099

Inhibition of Drp1 ameliorates diabetic retinopathy by regulating mitochondrial homeostasis
Exp Eye Res. 2022 Apr 28:109095. doi: 10.1016/j.exer.2022.109095. Online ahead of print.ABSTRACTDiabetic retinopathy (DR) is a potentially blinding complication resulting from diabetes mellitus (DM). Retinal vascular endothelial cells (RMECs) dysfunction occupies an important position in the pathogenesis of DR, and mitochondrial disorders play a vital role in RMECs dysfunction. However, the detailed mechanisms underlying DR-induced mitochondrial disorders in RMECs remain elusive. In the present study, we used High glucose (HG)-induced RMECs in vitro and streptozotocin (STZ)-induced Sprague-Dawley rats in vivo to explore th...

C-terminal binding protein 2 promotes high-glucose-triggered cell proliferation, angiogenesis and cellular adhesion of human retinal endothelial cell line
ConclusionThis study implicates that CtBP2 promotes HG-induced cell proliferation, angiogenesis and cellular adhesion, and CtBP2 might be a potential target in the prevention of DR.

Astaxanthin mediated regulation of VEGF through HIF1 α and XBP1 signaling pathway: An insight from ARPE-19 cell and streptozotocin mediated diabetic rat model
Exp Eye Res. 2021 Mar 28:108555. doi: 10.1016/j.exer.2021.108555. Online ahead of print.ABSTRACTBreakdown of outer blood-retina barrier (BRB) has been associated with the pathogenesis of diabetic retinopathy (DR) and diabetic macular edema (DME). Vascular endothelial growth factor (VEGF) might play a detrimental role in the pathogenesis of DME, a major clinical manifestation of DR. In the present study, we investigated the inhibitory mechanism of astaxanthin on VEGF and its upstream signaling pathways under in vitro and in vivo conditions. Astaxanthin has been observed to downregulate VEGF expression under hyperglycemic (H...

RNA therapeutics in ophthalmology - translation to clinical trials.
Abstract The use of RNA interference technology has proven to inhibit the expression of many target genes involved in the underlying pathogenesis of several diseases affecting various systems. First established in in vitro and later in animal studies, small interfering RNA (siRNA) and antisense oligonucleotide (ASO) therapeutics are now entering clinical trials with the potential of clinical translation to patients. Gene-silencing therapies have demonstrated promising responses in ocular disorders, predominantly due to the structure of the eye being a closed and compartmentalised organ. However, although the effic...

Inhibition of acetylcholinesterase attenuated retinal inflammation via suppressing NF- κB activation.
This study was aimed to dissect the role of ACHE in retinal inflammation, and its mechanism of action. Retinal inflammation was induced by intravitreal injection of tumor necrosis factor-α (TNF-α) in heterozygous ACHE knockout mice (ACHE+/-) and wild type mice (ACHE+/+). Donepezil, a well-known ACHE inhibitor, was administrated by daily gavage. Expression of ACHE and intercellular adherent molecule-1 (ICAM-1), infiltration of CD11b+ inflammatory cells, retinal leukostasis and vascular leakage was determined in both ACHE ± and ACHE+/+ mice. ARPE-19 cells, a human retinal pigment epithelial cell line, were cultured for ...
