The diabetic foot ulcer (DFU) is an invariably common complication of diabetes mellitus, it is also a significant cause of amputation as well as extended hospitalization. As most patients with DFU suffer from malnutrition, which has been related to improper metabolic micronutrients status, alterations can affect impaired wound healing process. Micronutrients and herbal remedies applications present a wide range of health advantages to patients with DFU. The purpose of this review is to provide current evidence on the potential effect of dietary supplementations such as vitamins A, C, D, E, magnesium, zinc, copper, iron, boron, and such naturally occurring compounds as Aloe vera, Naringin, and Radix Astragali (RA) and Radix Rehmanniae (RR) in the administration of lower extremity wounds, especially in DFU, and to present some insights for applications in the treatment of DFU patients in the future...

Zinc plays an important role in biological systems as bound and histochemically reactive labile Zn(2+). Although Zn(2+) concentration is in the nM range in cardiomyocytes at rest and increases dramatically under stimulation, very little is known about precise mechanisms controlling the intracellular distribution of Zn(2+) and its variations during cardiac function. Recent studies are focused on molecular and cellular aspects of labile Zn(2+) and its homeostasis in mammalian cells and growing evidence clarified the molecular mechanisms underlying Zn(2+)-diverse functions in the heart, leading to the discovery of novel physiological functions of labile Zn(2+) in parallel to the discovery of subcellular localization of Zn(2+)-transporters in cardiomyocytes...

Krüppel-like factor 14 (KLF14) is a member of the Cys2/His2 zinc-finger DNA-binding proteins. Despite strong evidence showing that a polymorphism in the Klf14 gene is closely linked to the development of type 2 diabetes (T2D), the physiological and metabolic functions of KLF14 still remain unclear. In the present study, we investigated the role of KLF14 in the regulation of hepatic gluconeogenesis. Adenoviruses expressing KLF14 (Ad-Klf14) or KLF14-specific shRNAs (Ad-shKlf14) were injected into normal C57BL/6J, db/db diabetic or high-fat diet-induced obese (DIO) mice...

Thermal degradation of insulin complicates its delivery and use. Previous efforts to engineer ultra-stable analogs were confounded by prolonged cellular signaling in vivo, complicating mealtime therapy and of unclear safety. We therefore sought an ultra-stable analog whose potency and duration of action on intravenous bolus injection in diabetic rats are indistinguishable from wild-type (WT) insulin. Here, we describe the structure, function and stability of such an analog: a 57-residue single-chain insulin (SCI) with multiple acidic substitutions...

Micronutrients are of fundamental importance in maintaining health status. However, data on their dietary intake are few particularly in persons with diabetes. The aim of this study was to evaluate in adults with type 1 diabetes (T1DM) attending a tertiary-level diabetes center in Southern Italy the intake of micronutrients (both vitamins and minerals) and the adherence to recommendations. Seven-day food records of 60 T1DM patients were analyzed. Micronutrient intake was evaluated based on the Italian food composition tables and expressed as amount per 1000 kcal of energy intake to adjust for possible underreporting...

Background: The solute carrier family 30 member 8 gene (SLC30A8) encodes a zinc transporter in the pancreatic beta cells and the major C-allele of a missense variant (rs13266634; C/T; R325W) in SLC30A8 is associated with an increased risk of type 2 diabetes (T2D). We hypothesized that the association between zinc intake and T2D may be modified by the SLC30A8 genotype. Results: We carried out a prospective study among subjects with no history cardio-metabolic diseases in the Malmö Diet and Cancer Study cohort (N = 26,132, 38% men; 86% with genotype data)...

Reactive oxygen and nitrogen species (ROS/RNS) are by-products of cellular physiological processes made from the metabolisms of intermediary nutrients. Although physiological defense mechanisms readily convert these species into water or urea, improper balance between their production and removal leads cells to experience oxidative stress (OS), which is harmful to cellular components. This may result in uncontrolled growth or ultimately to cell death. ROS/RNS are also closely related to the development of diabetes and its complications...

AIMS/HYPOTHESIS: Subcutaneous adipocyte hypertrophy is associated with insulin resistance and increased risk of type 2 diabetes, and predicts its future development independent of obesity. In humans, subcutaneous adipose tissue hypertrophy is a consequence of impaired adipocyte precursor cell recruitment into the adipogenic pathway rather than a lack of precursor cells. The zinc finger transcription factor known as zinc finger protein (ZFP) 423 has been identified as a major determinant of pre-adipocyte commitment and maintained white adipose cell function...

Zinc is an essential component of the insulin granule and it possibly modulates insulin secretion and signaling. Since insulin resistance is a hallmark in the development of type 2 diabetes mellitus, this study aimed at investigating if zinc supplementation is able to improve glucose tolerance and β-cell function in a model of insulin resistance. Male C57BL/6 mice were distributed in four groups according to the diet: normal fat (NF); normal fat supplemented with ZnCl₂ (NFZ); high-fat (HF); and, high-fat chow supplemented with ZnCl₂ (HFZ)...

In diabetes, oxidative stress and lipid abnormalities are common and pronounced and represent important factors that are involved in the development of complications of diabetes. Zinc deficiency generally induces oxidative stress, but it is well known that the antioxidant Ruta chalepensis has an effective modulator role in oxidative stress in metabolic diseases. The aim of this study was to investigate the effect of R. chalepensis extract on blood biochemical parameters, tissue zinc status and antioxidant systems in rats with diabetes that were fed zinc-deficient diets...

Zinc depletion during diabetes projects a role for zinc nutrition in this condition. This study explored whether zinc supplementation annuls diabetes-induced zinc dyshomeostasis through modulation of zinc transporters and metallothionein. Groups of hyperglycemic rats were exposed for six weeks to supplemental zinc (5 or 10-times the normal level). Intracellular zinc concentration and zinc transporter and metallothionein expression levels in different tissues were analysed. Depleted zinc concentrations in different organs were restored by zinc supplementation...

PLAGL1/ZAC1 undergoes parental genomic imprinting, is paternally expressed, and is a member of the imprinted gene network (IGN). It encodes a zinc finger transcription factor with anti-proliferative activity and is a candidate tumor suppressor gene on 6q24 whose expression is frequently lost in various neoplasms. Conversely, gain of PLAGL1 function is responsible for transient neonatal diabetes mellitus, a rare genetic disease that results from defective pancreas development. In the present work, we showed that Plagl1 up-regulation was not associated with DNA damage-induced cell cycle arrest...

The non-synonymous single nucleotide polymorphism (SNP) rs13266634 in human zinc transporter 8, ZnT8 (SLC30A8), leads to a R325 variant, which is associated with an increased risk of developing Type 2 Diabetes (T2D). Although the molecular details remain unknown, the mutation is thought to alter the kinetics of zinc transport into insulin granules in pancreatic β-cells. Nevertheless, analysis of ZnT8 sequences from several animals shows that the amino acid at position 325 is poorly conserved. Apart from this particular SNP, human ZnT8 also has two isoforms (splice variants) that differ in length regarding a 49 amino acid N-terminal extension...
