Abstract Kaempferol (KPF) is a dietary polyphenol reported to have various beneficial effects on human health. However, its molecular mechanisms in regulating lipid and glucose metabolism are not fully understood. This study examined the effects of KPF on obesity, dyslipidemia, and diabetes in Tsumura, Suzuki, Obese Diabetes (TSOD) mice. The six-week administration of KPF decreased fat weight, serum total cholesterol, and low-density lipoproteins (LDLs); increased high-density lipoproteins (HDLs); and improved glucose tolerance. Additionally, KPF increased LDL receptor (LDLR) and apolipoprotein A1 (ApoA1) gene expression and decreased serum resistin levels. These findings suggest that the decrease in LDL and the increase in HDL caused by KPF may be due to increases in hepatic LDLR and ApoA1 expression, respectively. Furthermore, it is possible that the improvement in glucose tolerance by KPF may occur via resistin reduction. These mechanisms may be parts of complex mechanism by which KPF improves metabolic syndrome.

Curcumin, the main polyphenol contained in turmeric root (Curcuma longa), has played a significant role in medicine for centuries. The growing interest in plant-derived substances has led to increased consumption of them also in pregnancy. The pleiotropic and multi-targeting actions of curcumin have made it very attractive as a health-promoting compound. In spite of the beneficial effects observed in various chronic diseases in humans, limited and fragmentary information is currently available about curcumin’s effects on pregnancy and pregnancy-related complications. It is known that immune-metabolic alterations occurring during pregnancy have consequences on both maternal and fetal tissues, leading to short- and long-term complications. The reported anti-inflammatory, antioxidant, antitoxicant, neuroprotective, immunomodulatory, antiapoptotic, antiangiogenic, anti-hypertensive, and antidiabetic properties of curcumin appear to be encouraging, not only for the management of pregnancy-related disorders, including gestational diabetes mellitus (GDM), preeclampsia (PE), depression, preterm birth, and fetal growth disorders but also to contrast damage induced by natural and chemical toxic agents. The current review summarizes the latest data, mostly obtained from animal models and in vitro studies, on the impact of curcumin on the molecular mechanisms involved in pregnancy pathophysiology, with the aim to shed light on the possible beneficial and/or adverse effects of curcumin on pregnancy outcomes.

Цель исследования состояла в выявлении информативных клеточных маркеров сосудистых осложнений, регенерации микрососудистой сети и воспаления в венозной крови здоровых волонтеров, больных с метаболическим синдромом, сахарным диабетом 1 и 2 типа. Методы. Обследованы больные с метаболическим синдромом (МС), диабетом 2 типа без осложнений, диабетом 1 типа средней степени тяжести и здоровые волонтеры. Диагноз пациентов подтвержден общеклиническими, биохимическими, коагулометрическими и иммуноферментными методами исследования, для оценки экспрессии антигенов использовался многопараметрический цитометрический анализ. Результаты. При анализе экспрессии маркеров показано изменение числа эндотелиальных клеток, мезенхимальных стволовых клеток (МСК) и гемопоэтических стволовых клеток (ГСК) в крови в зависимости от патологии. Эндотелиальные клетки миелоидного (CD45CD14CD34CD309CD144CD31) и немиелоидного (CD45CD14CD34CD309CD144CD31) происхождения, CD309-эндотелиальные клетки и МСК (CD44CD73CD90CD105) предлагаются в качестве маркеров повреждения эндотелия при диабетической симптоматике. При этом ГСК (CD45CD34) могут выступать ценным диагностическим и прогностическим маркером воспаления. Заключение. Для подтверждения сосудистых повреждений и прогноза развития осложнений при диабете 1 и 2 типа в венозной крови пациентов целесообразно оценивать эндотелиальные прогениторные клетки (ЭПК) не костномозговой локализации (CD31CD309CD144) и костномозговой локализации (CD34CD309), и ЭПК c высоким регенеративным потенциалом (CD45CD34CD31CD144). Циркулирующие ЭПК, формирующие колонии in vitro (CD45CD34CD31), рекомендуется использовать в качестве дифференциального маркера состояния регенерации эндотелия при диабете 2 типа. The aim of this study was to identify mesenchymal stem cells (MSC), hematopoietic stem cells (HSC), mature endothelial cells, and endothelial progenitor cells (EPC) in the blood of healthy volunteers, patients with metabolic syndrome, and type 1 and 2 diabetes mellitus as new, informative cellular markers of vascular complications, endothelial regeneration, and inflammation. Methods. The diagnosis was confirmed by general clinical, biochemical, coagulometeric and ELISA studies; multi-parameter cytometric assay was used for evaluation of antigen expression. Results. Changes in the count of MSC, HSC, mature endothelial cells, and endothelial progenitor cells in blood of patients with metabolic syndrome and type 1 and 2 diabetes depended on the type of pathology. We propose using endothelial cells of myeloid (CD45CD14CD34CD309CD144CD31) and non-myeloid origin (CD45CD14CD34CD309CD144CD31), CD309-endothelial cells, and MSCs with the CD44CD73CD90CD105 phenotype as nonspecific markers of endothelial damage in presence of diabetic symptoms. Furthermore, HSCs (CD45CD34) can be used as a valuable diagnostic and prognostic marker of inflammation. Conclusions. It is relevant to evaluate EPCs of non-bone marrow localization (CD31CD309CD144) and bone marrow localization (CD34CD309) and EPCs with a high regenerative potential (CD45CD34CD31CD144) in the blood of patients with type 1 and 2 diabetes to confirm the presence of vascular damage and predict development of complications. Circulating, in vitro colony-forming EPCs (CD45CD34CD31) are recommended as a differential marker for inhibition of endothelial regeneration in type 2 diabetes.

Immune Assays

Over the past decade it has become clear that probiotic and commensal interactions with mucosal dendritic cells in the lamina propria or epithelial cells lining the mucosa can modulate specific functions of the mucosal immune system. Innate pattern-recognition receptors such as TLRs, NLRs and CLRs play a crucial role in the host recognition of probiotics and other microorganism. Signalling via these receptors directly influences the chemokine and cytokine response of dendritic cells as well as the crosstalk between the epithelium and the immune cells in the lamina propria. This can influence the population of effector and regulatory T cell subsets in the mucosa. Immune assays with probiotics have shown that the in vitro immune response is both species and strain-specific. Such assays may be useful for the selection of probiotic strains that have beneficial effects on the regulation of intestinal inflammation but more comparative studies are needed to confirm recent findings. A better understanding of the molecular mechanisms of probiotics, the effect of dose, and frequency of administration on microbial sampling by mucosal APC will also help to clarify the value of immune assays as selection criteria for probiotics.

Diabetes, obesity, and metabolic syndrome are becoming epidemic both in developed and developing countries in recent years. Complementary and alternative medicines have been used since ancient era for the treatment of diabetes and cardiovascular diseases. Bitter melon is widely used as vegetables in daily food in Bangladesh and several other countries in Asia. The fruits extract of bitter melon showed strong antioxidant and hypoglycemic activities in experimental condition bothin vivoandin vitro. Recent scientific evaluation of this plant extracts also showed potential therapeutic benefit in diabetes and obesity related metabolic dysfunction in experimental animals and clinical studies. These beneficial effects are mediated probably by inducing lipid and fat metabolizing gene expression and increasing the function of AMPK and PPARs, and so forth. This review will thus focus on the recent findings on beneficial effect ofMomordica charantiaextracts on metabolic syndrome and discuss its potential mechanism of actions.

Beneficial Effects

Impaired wound healing and tissue regeneration have severe consequences on the patient’s quality of life. Micrograft therapies are emerging as promising and affordable alternatives to improve skin regeneration by enhancing the endogenous wound repair processes. However, the molecular mechanisms underpinning the beneficial effects of the micrograft treatments remain largely unknown. In this study, we identified the active protein-1 (AP-1) member Fos-related antigen-1 (Fra-1) to play a central role in the extracellular signal-regulated kinase- (ERK-) mediated enhanced cell migratory capacity of soluble micrograft-treated mouse adult fibroblasts and in the human keratinocyte cell model. Accordingly, we show that increased micrograft-dependent in vitro cell migration and matrix metalloprotease activity is abolished upon inhibition of AP-1. Furthermore, soluble micrograft treatment leads to increased expression and posttranslational phosphorylation of Fra-1 and c-Jun, resulting in the upregulation of wound healing-associated genes mainly involved in the regulation of cell migration. Collectively, our work provides insights into the molecular mechanisms behind the cell-free micrograft treatment, which might contribute to future advances in wound repair therapies.

Antioxidative Property

Geniposide, an iridoid glucoside, is a major component in the fruit of Gardenia jasminoides Ellis (Gardenia fruits). Geniposide has been experimentally proved to possess multiple pharmacological actions involving antioxidative stress, anti-inflammatory, antiapoptosis, antiangiogenesis, antiendoplasmic reticulum stress (ERS), etc. In vitro and in vivo studies have further identified the value of geniposide in a spectrum of preclinical models of diabetes mellitus (DM) and cardiovascular disorders. The antioxidative property of geniposide should be attributed to the result of either the inhibition of numerous pathological processes or the activation of various proteins associated with cell survival or a combination of both. In this review, we will summarize the available knowledge on the antioxidative property and protective effects of geniposide in DM and cardiovascular disease in the literature and discuss antioxidant mechanisms as well as its potential applications in clinic.

Individual Risk

Metabolic syndrome (MetS) – a clustering of pathological conditions, including abdominal obesity, hypertension, dyslipidemia and hyperglycaemia – is closely associated with the development of type 2 diabetes mellitus (T2DM) and a high risk of cardiovascular disease. A combination of multigenetic predisposition and lifestyle choices accounts for the varying inter-individual risk to develop MetS and T2DM, as well as for the individual amount of the increase in cardiovascular risk in those patients. A physically active lifestyle can offset about half of the genetically mediated cardiovascular risk. Yet, the extent to which standardized exercise programmes can reduce cardiovascular risk differs between patients. Exercise parameters, such as frequency, intensity, type and duration or number of repetitions, differentially target metabolic function, vascular health and physical fitness. In addition, exercise-induced molecular mechanisms are modulated by other patient-specific variables, such as age, diet and medication. This review discusses the molecular and cellular mechanisms underlying the effects of exercise training on cardiovascular risk specifically in patients with MetS and T2DM.

The Impact

Silicon (Si) is a ubiquitous element in soil with well-known beneficial effects under certain conditions, in several plant species, if supplied in available form for uptake. It may alleviate damage in various stress situations and may also promote growth when no obvious stressors are applied. Effects of Si are often linked to mitigation of oxidative stress, in particular to the induction of antioxidant defense mechanisms. In the work presented, the impact of silicon provision on pro-oxidant systems was investigated in cucumber. Plants of the F1 cultivar hybrid ‘Joker’ were grown under in vitro conditions in the absence of any applied external stressor. Silicon provision decreased H2O2 content and lowered lipid peroxidation in the leaves of the treated plants. This was paralleled by declining polyamine oxidase (PAO) and diamine oxidase (DAO) activities. Several PAO as well as lipoxygenase (LOX) genes were coordinately downregulated in Si-treated plants. Unlike in similar systems studied earlier, the Si effect was not associated with an increased transcript level of gene coding for antioxidant enzymes. These results suggest an inhibitory effect of Si provision on pro-oxidant amine oxidases, which may decrease the level of reactive oxygen species by retarding their production. This extends the molecular mechanisms linked to silicon effects onto redox balance in plants.
