Abstract
Indoxyl sulfate (IS) and p-cresyl sulfate (PCS), protein-bound uremic toxins, can induce oxidative stress and cause renal disease progression. However, the different cytotoxic effects on renal cells between IS and PCS are not stated. Due to uremic toxins are generally found in CKD patients, the mechanisms of uremic toxins-induced renal injury are required to study. Curcumin has anti-oxidant, anti-inflammatory and anti-apoptotic effects which may be potential used to protect against renal damage. In contrast, curcumin also exert cytotoxic effects on various cells. In addition, curcumin may reduce or enhance cytotoxicity combined with different chemicals treatments. However, whether curcumin may influence uremic toxins-induced renal injury is unclear. The goal of this study is to compare the different cytotoxic effects on renal cells between IS and PCS treatment, as well as the synergistic or antagonistic effects by combination treatments with curcumin and PCS. Our experimental result shows the PCS exerts a stronger antiproliferative effect on renal tubular cells than IS treatment. In addition, our study firstly demonstrates that curcumin enhances PCS-induced cell cytotoxicity through caspase-dependent apoptotic pathway and cell cycle alteration.

Abstract
Diabetes mellitus (DM) is a common metabolic disease which may cause several complications, such as diabetic nephropathy (DN). The routine medical treatments used for DM are not effective enough and have many undesirable side effects. Moreover, the global increased prevalence of DM makes researchers try to explore potential complementary or alternative treatments. Nutraceuticals, as natural products with pharmaceutical agents, have a wide range of therapeutic properties in various pathologic conditions such as DN. However, the exact underlying mechanisms have not been fully understood. The purpose of this review is to summarize recent findings on the effect of nutraceuticals on DN.

Abstract
Increased prevalence of metabolic syndrome (MetS) in the world influences quality of health in all respective countries, including Indonesia. Data from Indonesian Family Life Survey reported in 2019 showed that the prevalence of MetS in Indonesia currently is 21.66%, estimated with the provincial incidence ranging up to 50%; additionally, the most common components of MetS discovered in Indonesia were poor high-density lipoprotein (HDL) cholesterol and hypertension. Management treatment of MetS involves a combination of lifestyle changes and pharmacological interventions to decrease cerebrovascular disease. Various natural substances have been shown to govern any cardiovascular or metabolic disorders through different mechanisms, such as triggering anti-inflammation, lipid profile correction, sensitization of insulin reception, or blood glucose control. In Indonesia, the utilization of natural compounds is part of the nation's culture. The community widely uses them; even though in general, their effectiveness and safety have not been thoroughly assessed by rigorous clinical trials. Scientific evidence suggested that cinnamon, mangosteen, and curcumin, as well as their derived components possess a broad spectrum of pharmacological activity. In this review, an enormous potential of cinnamon, mangosteen, and curcumin, which originated and are commonly used in Indonesia, could be treated against MetS, such as diabetes, hyperlipidemia, hypertension, and obesity. The findings suggested that cinnamon, mangosteen, curcumin and their derivatives may reflect areas of promise in the management of MetS.

Abstract
One of the commonest causes of end-stage renal disease is diabetic kidney disease (DKD). Renal fibrosis, characterized by the accumulation of extracellular matrix (ECM) proteins in glomerular basement membranes and the tubulointerstitium, is the final manifestation of DKD. The TGF-β pathway triggers epithelial-to-mesenchymal transition (EMT), which plays a key role in the accumulation of ECM proteins in DKD. DCCT/EDIC studies have shown that DKD often persists and progresses despite glycemic control in diabetes once DKD sets in due to prior exposure to hyperglycemia called "metabolic memory." These imply that epigenetic factors modulate kidney gene expression. There is evidence to suggest that in diabetes and hyperglycemia, epigenetic histone modifications have a significant effect in modulating renal fibrotic and ECM gene expression induced by TGF-β1, as well as its downstream profibrotic genes. Histone modifications are also implicated in renal fibrosis through its ability to regulate the EMT process triggered by TGF-β signaling. In view of this, efforts are being made to develop HAT, HDAC, and HMT inhibitors to delay, stop, or even reverse DKD. In this review, we outline the latest advances that are being made to regulate histone modifications involved in DKD.

Abstract
BACKGROUND Type 1 diabetes mellitus (T1DM) is associated with increased risks of enteric infection. Paneth cells constitute the first line of the gut defense. Little is known about the impact of T1DM on the bactericidal function of intestinal Paneth cells. MATERIAL AND METHODS A T1DM mouse model was induced by intraperitoneal injection of streptozocin. The analysis of intestinal microbiota and the mucosal bactericidal assay were conducted to evaluate intestinal innate defense. Numbers of Paneth cells and their expression of related antimicrobial peptides were analyzed. Expression of total insulin receptor (IR) mRNA and relative levels of IR-A/IR-B were analyzed. The primary mouse small intestinal crypt culture was used to analyze the effect of insulin and glucose on the expression of related antimicrobial peptides of Paneth cells. RESULTS In T1DM mice, bacterial loads were increased and there was an alteration in the composition of the intestinal microflora. Exogenous bacteria had better survival in the small bowel of the T1DM mice. The expression of Paneth cell-derived antimicrobial peptides was significantly decreased in the T1DM mice, although the number of Paneth cells was increased. Relative levels of IR-A/IR-B in Paneth cells of diabetic mice were elevated, but the total IR mRNA did not change. Insulin treatment restored the expression of antimicrobial peptides and normalized the microbiota in the gut of T1DM mice. Subsequently, in vitro culture assay demonstrated that insulin rather than glucose was essential for the optimal expression of Paneth cell-derived antimicrobial peptides. CONCLUSIONS The bactericidal function of intestinal Paneth cells was impaired in STZ-induced diabetic mice, resulting in the altered intestinal flora, and insulin was essential for the optimal expression of Paneth cell-derived antimicrobial peptides.

Abstract
Diabetic nephropathy (DN) is a severe micro vascular complication accompanying diabetes mellitus that affects millions of people worldwide. End-stage renal disease occurs in nearly half of all DN patients, resulting in large medical costs and lost productivity. The course of DN progression is complicated, and effective and safe therapeutic strategies are desired. While the complex nature of DN renders medicines with a single therapeutic target less efficacious, Chinese medicine, with its holistic view targeting the whole system of the patient, has exhibited efficacy for DN management. This review aims to describe the experimental evidence for Chinese medicines in DN management, with an emphasis on the underlying mechanisms, and to discuss the combined use of herbs and drugs in DN treatment.

Abstract
Diabetic nephropathy (DN) remains a leading cause of mortality worldwide despite advances in its prevention and management. A comprehensive understanding of factors contributing to DN is required to develop more effective therapeutic options. It is becoming more evident that histone acetylation (HAc), as one of the epigenetic mechanisms, is thought to be associated with the etiology of diabetic vascular complications such as diabetic retinopathy (DR), diabetic cardiomyopathy (DCM), and DN. Histone acetylases (HATs) and histone deacetylases (HDACs) are the well-known regulators of reversible acetylation in the amino-terminal domains of histone and nonhistone proteins. In DN, however, the roles of histone acetylation (HAc) and these enzymes are still controversial. Some new evidence has revealed that HATs and HDACs inhibitors are renoprotective in cellular and animal models of DN, while, on the other hand, upregulation of HAc has been implicated in the pathogenesis of DN. In this review, we focus on the recent advances on the roles of HAc and their covalent enzymes in the development and progression of DN in certain cellular processes including fibrosis, inflammation, hypertrophy, and oxidative stress and discuss how targeting these enzymes and their inhibitors can ultimately lead to the therapeutic approaches for treating DN.

Abstract
Intestinal epithelial stem cells (IESCs) can differentiate into all types of intestinal epithelial cells (IECs) and Leucine-rich repeat-containing G protein-coupled receptor 5 (Lgr5) is a marker for IESC. Previous studies reported enhanced proliferation of IECs in diabetic mice. In this study, the in vitro differentiation of Lgr5 positive IESCs sorted from diabetic mice was further investigated. The diabetic mouse model was induced by streptozotocin (STZ), and crypt IECs were isolated from small intestines. Subsequently, Lgr5 positive IESCs were detected by flow cytometry (FCM) and sorted by magnetic activated cell sorting (MACS). Differentiation of the sorted IESCs was investigated by detecting the IEC markers in the diabetic mice using immunostaining, quantitative real-time reverse-transcription polymerase chain reaction (qRT-PCR), and Western blot analysis, which was compared with normal mice. We found that the proportion of Lgr5 positive cells in the crypt IECs of diabetic mice was higher than that of control mice (P < 0.05). Lgr5 positive IESCs could be significantly enriched in Lgr5 positive cell fraction sorted by MACS. Furthermore, the absorptive cell marker sucrase-isomaltase (SI) and the Paneth cell marker lysozyme 1 (Lyz1) were more highly expressed in the differentiated cells derived from Lgr5 positive IESCs of diabetic mice in vitro (P < 0.05). We demonstrate that the number of Lgr5 positive IESCs is significantly increased in the small intestines of STZ-induced diabetic mice. Lgr5 positive IESCs sorted from the diabetic mice can differentiate into a higher proportion of absorptive cells and Paneth cells in vitro. We characterized the expression of Lgr5 in the small intestine of diabetic mice, and sorted Lgr5 positive intestinal epithelial stem cells (IESCs) for investigating their differentiation in vitro. We proved that the quantity of Lgr5 positive IESCs was significantly increased in the small intestines of diabetic mice. IESCs sorted from the diabetic mice can differentiate into a higher proportion of absorptive cells and Paneth cells in vitro.

Abstract
Curcumin is the major polyphenolic constituent of an indigenous herb, Curcuma longa, found to have a wide range of applications right from its kitchen use as a spicy ingredient to therapeutic and medicinal applications in various diseases. Curcumin has been identified to have a plethora of biologic and pharmacologic properties owing to its antioxidant and anti-inflammatory activities. This pleiotropic regulation of redox balance of cell and inflammation might be the basis of curcumin's beneficial activities in various pathologic conditions including diabetic complications. This review summarizes various in vitro, in vivo studies done on curcumin and its therapeutic utility in diabetic micro-vascular complications. This review also emphasizes the importance of curcumin in addition to the existing therapeutic modalities in diabetic complications.

Abstract
Proliferative change and intestinal barrier dysfunction in intestinal mucosa of diabetes have been described, but the differentiation characteristics of intestinal epithelial cells (IECs) and the mechanisms in the IECs development remain unclear. To explore the intestinal epithelial constitution patterns and barrier function, the diabetic mouse model was induced by streptozotocin. Tight junctions between IECs were significantly damaged and the serum level of D-lactate was raised in diabetic mice (P < 0.05). The expression of Zo1 and Ocln in the small intestine of diabetic mice were lower, while the markers for absorptive cell (SI) and Paneth cell (Lyz1) were significantly higher than in control mice (P < 0.05). The expression of Msi1, Notch1, and Dll1 in small intestine gradually increased throughout the course of hyperglycemia in diabetic mice (P < 0.05). However, the expression of NICD, RBP-jκ, Math1, and Hes1 had a reverse trend compared with Msi1 and Notch1. Intestinal absorptive cells and Paneth cells had a high proliferation rate in diabetic mice. However, the intestinal barrier dysfunction associated with the decreased expressions of Zo1 and Ocln was detected throughout hyperglycemia. In conclusion, downregulation of Notch/Hes1 signal pathway caused by depressed Notch/NICD transduction is associated with the abnormal differentiation of IECs and intestinal barrier dysfunction in diabetic mice.

Abstract
Turmeric (Curcuma longa), a rhizomatous herbaceous perennial plant of the ginger family, has been used for the treatment of diabetes in Ayurvedic and traditional Chinese medicine. The active component of turmeric, curcumin, has caught attention as a potential treatment for diabetes and its complications primarily because it is a relatively safe and inexpensive drug that reduces glycemia and hyperlipidemia in rodent models of diabetes. Here, we review the recent literature on the applications of curcumin for glycemia and diabetes-related liver disorders, adipocyte dysfunction, neuropathy, nephropathy, vascular diseases, pancreatic disorders, and other complications, and we also discuss its antioxidant and anti-inflammatory properties. The applications of additional curcuminoid compounds for diabetes prevention and treatment are also included in this paper. Finally, we mention the approaches that are currently being sought to generate a "super curcumin" through improvement of the bioavailability to bring this promising natural product to the forefront of diabetes therapeutics.

Abstract
Background: Diabetes mellitus (DM) is a highly prevalent disease. Atrophy and spontaneous ulcers are the most common cutaneous manifestation of diabetic dermopathy (DD). Before spontaneous ulcers, we believe there is an underlying damage stage although the mechanism is unknown. Aims: To explore the expression of extracellular signal-regulated kinase1/2 (ERK1/2), its correlated upstream protein epidermal growth factor receptor (EGFR) and its downstream transcription factor E twenty-six (ETS)-like 1(ELK-1)in the damage of the diabetic rat skin, and to explore the role of ERK1/2 on the recessive damage to diabetic rat skin. Materials and Methods: Eighty Sprague-Dawley (SD) rats weighing 260-300 g were randomly divided into control and streptozotocin (STZ)-induced diabetes groups. After 0.5, 2, 4, and 8 weeks, the shaved skin specimens from the back of rats in both groups were collected to observe the histological characteristics of the skin, to measure the thickness of the epidermis and the dermis, and to observe the ultrastructure. Immunohistochemistry (IHC) and Western blot techniques were used to detect the expression and activation of ERK1/2, EGFR, ELK-1 in the skin of the rats. Results: There are ultrastructural changes in the DM skin. With the continuance of the diabetes course, the thicknesses of the epidermis and dermis decreased, and the expression of phospho-ERK1/2 (P-ERK1/2), EGFR, and ELK-1 was decreased gradually in the back skin of the diabetes rats. It was significantly lower in 4 and 8 week DM than that of the normal control (P < 0.05). The expression of P-EGFR and P-ERK1/2 in the back skin of the diabetes rats was positively correlated (r = 0.572 P < 0.05), and the positive correlation was also obtained between P-ERK1/2 and P-ELK-1 (r = 0.715, P < 0.05). Conclusion: The phenomenon of recessive damage exists in the skin of diabetes rats, which probably may relate to the weakness of the signal transduction: P-EGFR → ERK1/2 → ELK-1.

Abstract
SIGNIFICANCE Many physiological effects of natural antioxidants, their extracts or their major active components, have been reported in recent decades. Most of these compounds are characterized by a phenolic structure, similar to that of α-tocopherol, and present antioxidant properties that have been demonstrated both in vitro and in vivo. Polyphenols may increase the capacity of endogenous antioxidant defenses and modulate the cellular redox state. Such effects may have wide-ranging consequences for cellular growth and differentiation. CRITICAL ISSUES The majority of in vitro and in vivo studies conducted so far have attributed the protective effect of bioactive polyphenols to their chemical reactivity toward free radicals and their capacity to prevent the oxidation of important intracellular components. One possible protective molecular mechanism of polyphenols is nuclear factor erythroid 2-related factor (Nrf2) activation, which in turn regulates a number of detoxification enzymes. RECENT ADVANCES Among the latter, the heme oxygenase-1 (HO-1) pathway is likely to contribute to the established and powerful antioxidant/anti-inflammatory properties of polyphenols. In this context, it is interesting to note that induction of HO-1 expression by means of natural compounds contributes to prevention of cardiovascular diseases in various experimental models. FUTURE DIRECTIONS The focus of this review is on the role of natural HO-1 inducers as a potential therapeutic strategy to protect the cardiovascular system against various stressors in several pathological conditions.

Abstract
BACKGROUND AND PURPOSE Inflammation is involved in the development and/or progression of many diseases including diabetic complications. Investigations on novel anti-inflammatory agents may offer new approaches for the prevention of diabetic nephropathy. Our previous bioscreening of synthetic analogues of curcumin revealed C66 as a novel anti-inflammatory compound against LPS challenge in macrophages. In this study, we hypothesized that C66 affects high glucose (HG)-induced inflammation profiles in vitro and in vivo and then prevents renal injury in diabetic rats via its anti-inflammatory actions. EXPERIMENTAL APPROACH Primary peritoneal macrophages (MPM), prepared from C57BL/6 mice, were treated with HG in the presence or absence of C66. Diabetes was induced in Sprague-Dawley rats with streptozotocin, and the effects of C66 (0.2, 1.0 or 5.0 mg·kg(-1) ), administered daily for 6 weeks, on plasma TNF-α levels and expression of inflammatory genes in the kidney were assessed. KEY RESULTS Pretreatment of MPMs with C66 reduced HG-stimulated production of TNF-α and NO, inhibited HG-induced IL-1β, TNF-α, IL-6, IL-12, COX-2 and iNOS mRNA transcription, and the activation of JNK/NF-kB signalling. In vivo, C66 inhibited the increased plasma TNF-α levels and renal inflammatory gene expression, improved histological abnormalities and fibrosis of diabetic kidney, but did not affect the hyperglycaemia in these diabetic rats. CONCLUSIONS AND IMPLICATIONS The anti-inflammatory effects of C66 are mediated by inhibiting HG-induced activation of the JNK/NF-κB pathway, rather than by reducing blood glucose in diabetic rats. This novel compound is a potential anti-inflammatory agent and might be beneficial for the prevention of diabetic nephropathy.

Attenuation of high-glucose-induced inflammatory response by a novel curcumin derivative B06 contributes to its protection from diabetic pathogenic changes in rat kidney and heart.

Abstract
There is increasing evidence indicating that inflammatory processes are involved in the development and progression of diabetic complications. However, effective anti-inflammatory treatments for patients who have diabetic complications have yet been practically identified. Curcumin is a main component of Curcuma longa with numerous pharmacological activities. Previously, we synthesized a novel curcumin analogue (B06) that exhibited an improved pharmacokinetic and enhanced anti-inflammatory activity compared to curcumin. The present study aimed to test the hypothesis that B06 may reduce high-glucose-induced inflammation and inflammation-mediated diabetic complications. In vitro, pretreatment with B06 at a concentration of 5 μM significantly reduced the high-glucose-induced overexpression of inflammatory cytokines in macrophages. This anti-inflammatory activity of B06 is associated with its inhibition of c-Jun N-terminal kinase/nuclear factor κB activation. In vivo, despite that B06 administration at 0.2 mg · kg(-1) · d(-1) for 6 weeks did not affect the blood glucose profile of diabetic rats, the B06-treated animals displayed significant decreases in inflammatory mediators in the serum, kidney, and heart and renal macrophage infiltration. This was accompanied with an attenuation of diabetes-induced structural and functional abnormalities in the kidney and heart. Taken together, these data suggest that the novel derivative B06 might be a potential therapeutic agent for diabetic complications via an anti-inflammatory mechanism and support the potential application in diabetic complication therapy via anti-inflammatory strategy.

Abstract
1. Increasing evidence suggests that epigenetic factors might regulate the complex interplay between genes and the environment, and affect human diseases, such as diabetes and its complications. 2. Clinical trials have underscored the long lasting beneficial effects of strict glycaemic control for reducing the progression of diabetic complications. They have also shown that diabetic complications, such as diabetic nephropathy, a chronic kidney disorder, can continue even after blood glucose normalization, suggesting a metabolic memory of the prior glycaemic state. 3. Dysregulation of epigenetic post-transcriptional modifications of histones in chromatin, including histone lysine methylation, has been implicated in aberrant gene regulation associated with the pathology of diabetes and its complications. Genome-wide studies have shown cell-type specific changes in histone methylation patterns under diabetic conditions. In addition, studies in vascular cells have shown long lasting changes in epigenetic modifications at key inflammatory gene promoters after prior exposure to diabetic conditions, suggesting a possible mechanism for metabolic memory. 4. Recent studies have shown roles for histone methylation, DNA methylation, as well as microRNA in diabetic nephropathy. Whether these epigenetic factors play a role in metabolic memory of diabetic kidney disease is less well understood. 5. The incidence of diabetes is growing rapidly, as also the cost of treating the resulting complications. A better understanding of metabolic memory and the potential involvement of epigenetic mechanisms in this phenomenon could enable the development of new therapeutic targets for the treatment and/or prevention of sustained diabetic complications.
