Summary: This study analyzed the mechanism by which NOX2 contributes to Ang II-induced ET-1 production in human microvascular endothelial cells. The results showed that high-fat diet increased the expression of Ang II and ET-1 in wild-type mice, but not in Nox2-deficient mice. In vitro experiments revealed that Ang II promoted NOX2 expression through induction of the Oct-1 protein and increased production of superoxide anions. Inhibition of Oct-1 and superoxide attenuated Ang II-induced ET-1 production.

Summary: The study aimed to investigate the effects of resistance training on renal renin-angiotensin system components and inflammatory mediators in diabetic rats. The results showed that resistance training improved kidney function in diabetic rats by modulating intrarenal RAS towards the ACE2/Ang 1-7 axis and reducing inflammatory cytokines levels.

Summary: Diabetic nephropathy is characterized by proteinuria, renal dysfunction, renal fibrosis, and infiltration of macrophages derived from peripheral monocytes. Research focuses on the control of monocyte recruitment and modulation of macrophage polarization in the context of diabetic nephropathy.

Summary: This study found that in a mouse model of diabetic nephropathy, there were elevated lactate levels and impaired energy metabolism in the kidneys. Treatment with an angiotensin-receptor blocker (ARB) improved these abnormalities. Increased expression of lactate dehydrogenase isoforms, specifically LdhA in the proximal tubule, was also observed. Urinary lactate levels were found to be predictive of clinical outcomes in diabetic patients with kidney disease.

Summary: This study aimed to explore the effects of TIMP-1 on LC-mediated regulation of AngII-induced MF and its underlying mechanisms. AngII treatment upregulated Axl, alpha-SMA, and MMP3 expression and downregulated STAT4 and TIMP1 expression. LC and TIMP-1-OE transfection further suppressed cell viability and migration induced by Ang II and upregulated apoptosis, whereas si-TIMP-1 had the opposite effect. TIMP-1 is therefore a potential therapeutic target for delaying MF progression.

Summary: The study shows that Ferrostatin-1 can effectively protect astrocytes from ferroptosis induced by Angiotensin II, reduce the production of inflammatory factors, and exert protective effects by activating the Nrf2/HO-1 signaling pathway.

Summary: Supplementation of carnosine and anserine can effectively reduce diabetic nephropathy in rodents. However, the exact mechanism of their nephroprotective action in diabetes, whether it is through local protection or improved systemic glucose homeostasis, remains uncertain.

Summary: Ghrelin is an appetite-enhancing anabolic hormone secreted from the stomach, while Angiotensin II plays an important role in maintaining sodium and potassium levels in body fluids and regulating arterial blood pressure. The study investigated the time-dependent changes in plasma ghrelin and angiotensin II levels during the development and progression of diabetic nephropathy in an experimental rat model, finding that plasma angiotensin and serum creatinine levels increased over time while plasma ghrelin levels decreased during the progression of diabetes and the development of diabetes-related nephropathy.

Summary: Diabetic nephropathy is a common disease leading to end-stage renal disease. Chronic activation of the RAAS contributes to kidney inflammation and fibrosis, resulting in kidney disease. Targeting the reno-protective arm of the RAAS provides potential therapeutic options for improving kidney inflammation and fibrosis in diabetic nephropathy.

Summary: Angiotensin II (Ang II) is a key component of the renin-angiotensin-aldosterone system and is associated with cardiopathology. High levels of Ang II have been linked to inflammatory conditions such as coronary heart disease, obesity, and type 2 diabetes. This study evaluated the cellular effects of Ang II on THP-1-derived macrophages, showing that it stimulates differentiation markers and proinflammatory markers while decreasing an M2 marker. Ang II also induces calcium overload, increases reactive oxygen species, and arrests cells in the G1 phase, primarily through the angiotensin II type 1 receptor (AT1R).

Summary: The importance of early diagnosis and treatment of diabetes and its cutaneous complications is increasingly recognized. High glucose affects collagen gene expression in human dermal fibroblasts, leading to an imbalance of matrix metalloproteinases and tissue inhibitors of metalloproteinases. Inhibiting MMP-2 and MMP-9 can alleviate collagen deposition disorder in the skin of diabetic mice.

Summary: Diabetic nephropathy is a persistent microvascular problem of diabetes mellitus characterized by elevated albumin excretion in urine and impaired renal function. The pathogenesis is multifactorial and requires novel treatment approaches beyond glucose and blood pressure control.
