Project description:Dry age-related macular degeneration (AMD) is one of the main diseases that causes blindness in humans and the number of cases is increasing every year, but effective treatments are not available, arbutin (ARB) has been reported to have antioxidant, anti-inflammatory, and anti-aging effects in other age-related diseases. However, whether it can help treat dry AMD remains unknown.in this study, we found 10-100 μM ARB concentration-dependently reversed the H2O2-induced viability decline in HRPECs, and ARB inhibited H2O2-induced HRPEC ROS production and apoptosis by changing the expression of antioxidant and apoptosis-related genes and proteins. Transcriptome sequencing and western blotting showed that ARB reduced ERK1/2 and P-38 phosphorylation to prevent H2O2-induced oxidation damage. We concluded ARB reversed the H2O2-induced decline in HRPEC activity, which was related to inhibition of ROS production and apoptosis. The ERK1/2 and P38 MAPK signaling pathways may have mediated this process.

Project description:Angiotensin receptor blockade (ARB) and sodium-glucose co-transporter 2 inhibitor (SGLT2i) have been used as the standard therapy for patients with diabetic kidney disease (DKD). However, how these two drugs possess additive renal protective effects remains unclear. Here, we conducted single cell RNA-sequencing to profile the kidney cell transcriptome of db/db mice treated with vehicle, ARB, SGLT2i, or both drugs and db/m mice. We identified 10 distinct clusters of kidney cells with predominant proximal tubular (PT) cells. We found that ARB has more anti-inflammatory and anti-fibrosis effects while SGLT2i affects more mitochondrial function. We also identified a new PT subcluster which was increased in DKD but reversed by treatments.This new subcluster was also confirmed by Immunostaining of mouse and human kidneys with DKD. Together, our study reveal kidney cell-specific gene signatures in response to ARB and SGLT2i and also identified a new PT subcluster which provides new insight into DKD.

Project description:Treatment with angiotensin converting enzyme inhibitors (ACEI) or angiotensin receptor blockers (ARB) has been shown to have anti-inflammatory effects such as decreased growth factors and cytokines in animal models, this effect however, has not been investigated in kidney transplant recipients. We aimed to study the effect of ACEI or ARB treatment on intragraft gene expression profiles of transplant kidney biopsies using microarrays. Both groups had similar demographic characteristics in terms of age, race, sex, type of transplant, previous history of transplantation or acute rejection, panel reactive antibody levels, and immunosuppressive treatment. There were no differences in acute and chronic Banff allograft injury scores between the 2 Groups. Intragraft gene expression profiles of ACEI or ARB treated Group 2 biopsies showed decreased gene transcripts of interferon-gamma and rejection-associated transcripts (GRIT) and constitutive macrophage-associated transcripts (CMAT) compared to Group 1 biopsies. There were no statistically significant differences in expression of cytotoxic T cell (CAT), regulatory T cell (TREG), B-cell (BAT), natural killer cell (NKAT), or endothelial cell-associated transcripts (ENDAT) between the 2 Groups. Our data suggest that exposure to ACEI or ARB was associated with down-regulation of GRIT and CMAT. This anti-inflammatory effect of ACEI or ARB treatment could be an additional benefit in kidney transplant recipients.

This anti-inflammatory effect of ACEI or ARB treatment could be an additional benefit in kidney transplant recipients. We identified 29 near normal biopsies with chronic sum allograft injury score (ct+ci+cv) ⤠3 for gene expression profiling comparing 2 groups; Group 1 (n=16), patients with no exposure of ACEI or ARB treatment and Group 2 patients (n=13) with exposure to ACEI or ARB at least 6 months prior to kidney biopsy. Biopsies with a diagnosis of acute or chronic rejection, recurrent or de novo glomerular disease, or polyoma nephropathy were excluded.

Project description:Before morphological changes at the early stage of hypertension, how overloaded hypertension influences the transcriptomic profile of the left atrium remains unclear, therefore, RNA-sequencing was performed to define the RNA expressing profiles of left atrium in spontaneously hypertensive rats (SHR) and normotensive Wistar-Kyoto rats (WKY) as a control group. At the same time, we compared the RNA expressing profiles changes in ARB-treated (valsartan, 30mg/kg/d) and ARNI-treated (sacubitril/valsartan, 60mg/kg/d) SHR to reveal the distinct effects on the left atrium. A total of 1558 differentially expressed genes were found in the left atrium between WKY rats and SHRs. Bioinformatics analysis revealed that these mRNAs could regulate the upstream pathways in atrial remodeling through atrial fibrosis, inflammation, electrical remodeling, and cardiac metabolism. The regulated transcripts of left atrial tissue in both the ARB-treated and ARNI-treated groups were related to metabolism. Compared with ARB, transcripts in ARNI-treated rats were mapped to the cGMP-PKG signaling pathway.
