Abstract
Diabetic nephropathy (DN) is one of the most common complications of diabetes, and its main manifestations are progressive proteinuria and abnormal renal function, which eventually develops end stage renal disease (ESRD). The pathogenesis of DN is complex and involves many signaling pathways and molecules, including metabolic disorders, genetic factors, oxidative stress, inflammation, and microcirculatory abnormalities strategies. With the development of medical experimental techniques, such as single-cell transcriptome sequencing and single-cell proteomics, the pathological alterations caused by kidney cell interactions have attracted more and more attention. Here, we reviewed the characteristics and related mechanisms of crosstalk among kidney cells podocytes, endothelial cells, mesangial cells, pericytes, and immune cells during the development and progression of DN and highlighted its potential therapeutic effects.

Abstract
Polygoni Cuspidati Rhizoma et Radix, the dry roots and stems of Reynoutria japonica Houtt (called Huzhang, HZ in Chinese), is a traditional and popular chinese medicinal herb for thousands of years. As a widely used ethnomedicine in Asia including China, Japan, and Korea, HZ can invigorate the blood, cool heat, and resolve toxicity, which is commonly used in the treatment of favus, jaundice, scald, and constipation. However, HZ is now considered an invasive plant in the United States and many European countries. Therefore, in order to take advantage of HZ and solve the problem of biological invasion, scholars around the world have carried out abundant research studies on HZ. Until now, about 110 compounds have been isolated and identified from HZ, in which anthraquinones, stilbenes, and flavonoids would be the main bioactive ingredients for its pharmacological properties, such as microcirculation improvement, myocardial protective effects, endocrine regulation, anti-atherosclerotic activity, anti-oxidant activity, anti-tumor activity, anti-viral activity, and treatment of skin inflammation, burns, and scalds. HZ has a variety of active ingredients and broad pharmacological activities. It is widely used in health products, cosmetics, and even animal husbandry feed and has no obvious toxicity. Efforts should be made to develop more products such as effective drugs, health care products, cosmetics, and agricultural and animal husbandry products to benefit mankind.

Abstract
Diabetic kidney disease (DKD) is a serious microvascular complication of diabetes and is the leading cause of end-stage renal disease (ESRD). Persistent proteinuria is an important feature of DKD, which is caused by the destruction of the glomerular filtration barrier (GFB). Glomerular endothelial cells (GECs) and podocytes are important components of the GFB, and their damage can be observed in the early stages of DKD. Recently, studies have found that crosstalk between cells directly affects DKD progression, which has prospective research significance. However, the pathways involved are complex and largely unexplored. Here, we review the literature on cellular crosstalk of GECs and podocytes in the context of DKD, and highlight specific gaps in the field to propose future research directions. Elucidating the intricates of such complex processes will help to further understand the pathogenesis of DKD and develop better prevention and treatment options.

JOURNAL OF ETHNOPHARMACOLOGY 2020; 253:112682. [PMID: 32087318 DOI: 10.1016/j.jep.2020.112682] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/22/2019] [Revised: 12/05/2019] [Accepted: 02/17/2020] [Indexed: 06/10/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Huangkuisiwufang (HKSWF) is composed of Abelmoschus manihot (L.) Medik., Astragalus mongholicus, Polygonum cuspidatum, Curcuma longa L. Abelmoschus Manihot (L.) Medik. has been widely used for the treatment of chronic renal disease, oral ulcers and burn in China for centuries (Committee of the Pharmacopoeia of PR China, 2010). Abelmoschus manihot (L.) Medik., Polygonum cuspidatum, Curcuma longa L. have been mainly applied in folk medicine for their therapeutic effects on diabetes, cancer, heart disease and other diseases. AIM OF THE STUDY We aimed to investigate the renoprotective function of HKSWF in anti-Thy nephritis model and clarify the relevant mechanisms. MATERIALS AND METHODS One week after the model of glomerulonephritis created by injecting anti-thymocyte serum (ATS), rats were treated with Huangkui capsule, enalapril or HKSWF by gavage for a period of 8 weeks. The therapeutic effect was evaluated by detection of proteinuria, plasma creatine, blood urea nitrogen (BUN), podocyte injury, glomerular accumulation of extracellular matrix (ECM) and the markers of oxidative stress and renal fibrosis. RNA Sequencing (RNA-seq), KEGG and western blotting analysis were performed to indicate the signaling pathway involved in the therapeutic effect of HKSWF. RESULTS Nephritic rats presented the increase of BUN, serum creatinine (Scr), proteinuria, podocyte damage, glomerular fibrosis, Ang II type 1 receptor (AT1R), and the reduction of creatinine clearance (Ccr). In contrast, application of HKSWF to nephritic rats decreased the levels of BUN and proteinuria, promoted mesangial cell recovery and improved oxidative stress level and podocyte injury. KEGG analysis revealed that pyruvate metabolism was the most significantly upregulated pathway in rats treated with HKSWF compared to disease control group. Increased pyruvate dehydrogenase and PAI-1 caused by nephritis was inhibited by HKSWF interposition. Furthermore, dichloroacetate sodium (DCA), an agonist of pyruvate dehydrogenase, could stimulate PAI-1 expression, which was suppressed by HKSWF. CONCLUSION Chinese herbal preparation HKSWF has remarkable curative effects on glomerulonephritis animals. HKSWF attenuates pyruvate dehydrogenase to improve glomerular injury.

Abstract
Salacia oblonga is used to treat diabetes, hypocholesteremia, gonorrhea, rheumatism, asthma, inflammation, oxidative stress, etc. In the present study, the antidiabetic activity of S. oblonga methanolic root extracts collected from three geographical locations, viz., Eleshwaram (Andhra Pradesh), Thoothukudi (Tamil Nadu), and Karwar (Karnataka), was studied in vitro. Among the three extracts, S. oblonga root extracts from Eleshwaram showed maximum α-glucosidase and α-amylase inhibitory activities, indicating better antidiabetic activity. Acute toxicity studies of S. oblonga carried out in Albino Wistar rats showed no toxicity. Further, in vivo studies showed antidiabetic and antilipidemic activities in Albino Wistar rats with induced type II diabetes mellitus. Type II diabetes mellitus was induced in the experimental rats by intraperitoneal injection of nicotinamide and streptozotocin. The rats were orally fed different doses (ranging from 0 to 400 mg/kg body weight) of S. oblonga root extracts from Eleshwaram for 14 days. Blood glucose, lipid, bilirubin, and creatinine levels were analyzed on day 0, 7, and 14. The S. oblonga root extract from Eleshwaram decreased the glucose levels in a dose-dependent manner as well as the lipid, creatinine, and bilirubin levels in diabetic rats. Thus, the present study demonstrates antidiabetic and antilipidemic properties of S. oblonga root extracts.

Polygonum cuspidatum extract attenuates fructose-induced liver lipid accumulation through inhibiting Keap1 and activating Nrf2 antioxidant pathway. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2019; 63:152986. [PMID: 31310912 DOI: 10.1016/j.phymed.2019.152986] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/23/2019] [Revised: 06/04/2019] [Accepted: 06/08/2019] [Indexed: 06/10/2023]
Abstract
BACKGROUND Polygonum cuspidatum has been used in traditional Chinese medicine to treat liver disorders associated with oxidative stress, inflammation and lipid accumulation for centuries in patients. PURPOSE The aim of this study was to examine whether P. cuspidatum extract (PCE) prevented against fructose-induced liver lipid accumulation via regulating Kelch-like ECH-associated protein 1 (Keap1)/nuclear factor erythroid 2-related factor 2 (Nrf2) pathway. METHOD PCE was administered orally to male Sprague-Dawley rats given 10% fructose drinking water for 6 weeks at 80 and 160 mg/kg once daily for 11 weeks. RESULTS PCE significantly alleviated liver lipid accumulation in fructose-fed rats with metabolic syndrome. It also inhibited Keap1, activated Nrf2 antioxidant pathway, resulting in the suppression of oxidative stress, evidenced by reducing hydrogen peroxide (H2O2), malondialdehyde (MDA) and hydroxy radical (OH•) levels, and increasing glutathione (GSH)/oxidized glutathione (GSSG) ratio as well as superoxidase dismutase (SOD) and catalase (CAT) activity in the liver of fructose-fed rats. Additionally, PCE up-regulated peroxisome proliferator activated receptor-α (PPAR-α), and down-regulated sterol regulatory element binging protein 1 (SREBP-1), fatty acid synthetase (FAS) and stearoyl-CoA desaturase-1 (SCD-1) in this animal model, being consistent with its reduction of triglyceride (TG) levels. CONCLUSION These results demonstrate that PCE reduces oxidative stress, and prevent lipid accumulation in the liver of fructose-fed rats possibly by targeting the Keap1/Nrf2 pathway. PCE may be a promising therapeutic strategy for fructose-associated liver lipid accumulation.

Abstract
Diabetes mellitus (DM), a chronic metabolic disease, severely affects patients' life and intensively increases risks of developing other diseases. It is estimated that 0.4 billion individuals worldwide are subjected to diabetes, especially type 2 diabetes mellitus. At present, although various synthetic drugs for diabetes such as Alogliptin and Rosiglitazone, etc. have been used to manage diabetes, some of them showed severe side effects. Given that the pathogenesis of type 2 diabetes mellitus, natural occurring drugs are beneficial alternatives for diabetes therapy with low adverse effects or toxicity. Recently, more and more plant-derived extracts or compounds were evaluated to have anti-diabetic activities. Their anti-diabetic mechanisms involve certain key targets like α-glucosidase, α-amylase, DPP-4, PPAR γ, PTP1B, and GLUT4, etc. Here, we summarize the newly found anti-diabetic (type 2 diabetes mellitus) natural compounds and extracts from 2011-2017, and give the identification of their molecular targets. This review could provide references for the research of natural agents curing type 2 diabetes mellitus (T2DM).

Abstract
Oxidative stress plays a major role in the development and progression of diabetic nephropathy (DN). In this study, the potential protective effect of ginger (Zingiber officinale) rhizome extract on hyperglycemia-induced oxidative stress, inflammation and apoptosis was investigated. An experimental diabetic rat model was induced by intraperitoneal injection of streptozotocin. Diabetic rats were treated orally with 400 or 800 mg/kg/day Z. officinale extract for six weeks. Diabetic animals exhibited elevated blood glucose levels and glycated hemoglobin (HbA1c) with altered lipid profile. Blood urea nitrogen, serum creatinine and urea, and urine albumin levels were significantly increased in diabetic rats. Treatment with Z. officinale ameliorated hyperglycemia, hyperlipidemia and kidney function. In addition, Z. officinale minimized the histological alterations in the kidney of diabetic rats. Chronic hyperglycemia resulted in a significant increase in malondialdehyde, protein carbonyl, pro-inflammatory cytokines, cytochrome c and caspase-3 in the kidney of rats. Z. officinale extract significantly attenuated oxidative stress, inflammation and apoptosis, and enhanced antioxidant defenses in the diabetic kidney. In conclusion, this study strongly suggests that Z. officinale rhizome extract exerts a protective role against diabetes-induced renal injury by ameliorating oxidative stress, inflammation and apoptosis.

Abstract
Mesangial cell proliferation contributes to the development of glomerulosclerosis in diabetic nephropathy. This study was aimed at determining whether Osteomeles schwerinae (OSSC) extract can ameliorate renal damage in Spontaneously Diabetic Torii (SDT) rats. OSSC extract (100 and 250 mg/kg/day) was administered to the SDT rats through oral gavage for 17 weeks. At the end of the experiment, glucose, HbA1c, and albuminuria were measured. In addition, the levels of mesangial proliferation-related proteins were determined by western blotting and immunohistochemistry. Our results show that albuminuria, accumulation of the extracellular matrix (ECM), and renal expansion were markedly restored by OSSC extract administration. The OSSC treatment also inhibited α-smooth muscle actin and transforming growth factor-β1 protein expression. In addition, OSSC and its bioactive compounds hyperoside and quercitrin inhibited the platelet-derived growth factor-BB (PDGF-BB)/platelet-derived growth factor-B receptor (PDGFR-β) ligand binding in an in vitro assay. Taken together, these results indicate that OSSC inhibits ECM accumulation and mesangial proliferation of the glomeruli in SDT rats through inhibition of the interaction between PDGF-BB and PDGFR-β. OSSC has ameliorating effects on the initiation and progression of diabetes complications and can be used for the treatment of early diabetic renal dysfunction.

Abstract
The worldwide increasing incidence of type 2 diabetes has fueled an intensified search for food and herbal remedies with preventive and/or therapeutic properties. Polygonum cuspidatum Siebold & Zucc. (Polygonaceae) is used as a functional food in Japan and South Korea, and it is also a well-known traditional antidiabetic herb used in China. In this study, dual high-resolution α-glucosidase and protein-tyrosine phosphatase 1B (PTP1B) inhibition profiling was used for the identification of individual antidiabetic constituents directly from the crude ethyl acetate extract and fractions of P. cuspidatum. Subsequent preparative-scale HPLC was used to isolate a series of α-glucosidase inhibitors, which after HPLC-HRMS and NMR analysis were identified as procyanidin B2 3,3″-O-digallate (3) and (-)-epicatechin gallate (5) with IC50 values of 0.42 ± 0.02 and 0.48 ± 0.0004 μM, respectively, as well as a series of stilbene analogues with IC50 value in the range from 6.05 ± 0.05 to 116.10 ± 2.04 μM. In addition, (trans)-emodin-physcion bianthrone (15b) and (cis)-emodin-physcion bianthrone (15c) were identified as potent PTP1B inhibitors with IC50 values of 2.77 ± 1.23 and 7.29 ± 2.32 μM, respectively. These findings show that P. cuspidatum is a potential functional food for management of type 2 diabetes.
