BACKGROUND: Diabetic nephropathy (DN), the leading cause of end-stage renal disease, is acknowledged as an independent risk factor for cardiovascular disease, which underlines the urgent need for new medications to DN. Dihydroquercetin (DHQ), an important natural dihydroflavone, exerts significant antioxidant, anti-inflammatory, and antifibrotic properties, but its effects on DN have not been investigated yet. PURPOSE: We aimed to explore the kidney protection effects of DHQ on DN rats induced by high-fat diet/streptozotocin in vivo and the underlying mechanisms of DHQ on renal cells including HBZY-1 and HK2 exposed to high glucose in vitro...

Endothelial dysfunction contributes to poor cardiovascular prognosis in patients with type 2 diabetes mellitus (T2DM) and coronary artery disease (CAD). The effect of dipeptidyl peptidase-4 inhibitors on endothelial function remains controversial. We sought to compare the effects of linagliptin and voglibose on endothelial function, as assessed by reactive hyperemia-peripheral arterial tonometry (RH-PAT). Sixteen patients with newly diagnosed T2DM and CAD were randomized 1:1 to linagliptin (5 mg, once-daily) or voglibose (0...

Diabetic mellitus (DM) is a disease that affects glucose homeostasis and causes complications, such as diabetic nephropathy (DN). For early diagnosis of DN, microalbuminuria is currently one of the most frequently used biomarkers. However, more early diagnostic biomarkers are desired in addition to microalbuminuria. In this study, we performed comprehensive proteomics analysis of urine proteomes of diabetic mellitus patients without microalbuminuria and healthy volunteers to compare the protein profiles by mass spectrometry...

d-ribose (Rib), a reactive glycation compound that exists in organisms, abnormally increases in the urine of diabetic patients and can yield large amounts of advanced glycation end products (AGEs), leading to cell dysfunction. However, whether cellular proteins are sensitive to this type of glycation is unknown. In this study, we found that cellular AGEs accumulate in Chinese hamster ovary (CHO) cells with increased Rib concentration and administration time. Mass spectrum analysis of isolated AGE-modified proteins from cell lysates showed that glucose-regulated protein 78 kD (GRP78) is one of the main ribosylated proteins...

Skeletal muscle, hepatic insulin resistance, and beta cell dysfunction are the characteristic pathophysiological features of type 2 diabetes mellitus. GABA has an important role in pancreatic islet cells. The present study attempted to clarify the possible mechanism of GABA to improve glucose tolerance in a model of type 2 diabetes mellitus in rats. Fifty Wistar rats were divided into five groups: NDC that was fed the normal diet, CD which received a high-fat diet with streptozotocin, CD-GABA animals that received GABA via intraperitoneal injection, plus CD-Ins1 and CD-Ins2 groups which were treated with low and high doses of insulin, respectively...
