Full textObesity is often defined as the significant increase in proportion of fat mass in total body mass. Nowadays, obesity exhibits pandemic proportions and acquires character of the global health and social problem, as it represents the risk factor for the development of non-communicable diseases, especially type 2 diabetes mellitus (T2DM) and cardiovascular diseases. Adipokines are molecules secreted by adipose tissue which play an important role in the regulation of various processes in the human organism. Adiponectin (ADN) is an adipokine with anti-diabetic, anti-inflammatory and anti-atherogenic effects. During development of, above all, central obesity, disorders in the secretory profile of adipose tissue are arising, decline in serum concentrations of ADN advents, which leads to occurrence of numerous cardiometabolic disorders. The aim of study is to examine the significance of determining serum ADN in assessing the cardiometabolic profile, and determining its association with the estimated ten-year risk of developing T2DM in obese persons. Cross-sectional study conducted at the Clinic for Endocrinology, Diabetes and Metabolic Disorders, Clinical Center of Vojvodina, included 65 persons with hyperalimentation type of obesity. Ten-year risk of developing T2DM was assessed and appropriate anthropometric, laboratory and morphological evaluations were performed. Persons with lower serum ADN had worse cardiometabolic profile compared to those with normal serum ADN value, while there was no difference in the level of ten-year risk of developing T2DM between two groups. Also, subjects with metabolic syndrome (MS) and subjects with nonalcoholic fatty liver disease (NAFLD) had lower serum ADN compared to persons without MS and to those without NAFLD. There is a significant association of serum ADN with a larger number of cardiometabolic profile indicators but not with the estimated ten-year risk of developing T2DM.

Full textFaced with the increasing prevalence of type II diabetes, the development of new therapeutic strategies is one of the major public health issues. Our research group studies focus on apelin, an adipokine overexpressed in obesity, that is beneficial and improves insulin sensitivity in obese and insulin resistant mice, by acting essentially on the muscle lipid metabolism. However, the role of apelin on liver metabolism has not been addressed yet. We thus studied, in obese and insulin resistant mice, the effects of a chronic apelin treatment on the main hepatic metabolic functions, as well as the expression and the regulation of apelin receptor, named APJ, in different hepatic cell types. We have shown that glycogen stores were not modified, but hepatic steatosis was reduced by 40% after 4 weeks of apelin treatment. This was associated to a decreased gene expression of SREBP-1c and FAS, suggesting that de novo lipogenesis was reduced by this treatment. In addition, lipid oxidation and secretion of VLDL were decreased. These effects seem to be the consequence of the treatment on the global amelioration of insulin sensitivity, rather than a direct apelin effect on the liver. Indeed, even though APJ gene expression is increased in the liver of obese and insulin resistant mice, the immunofluorescence experiments did not reveal the presence of APJ in hepatocytes. However, the presence of APJ in another cell type doesn't rule out indirect effects on the hepatic metabolism. Eicosapentaenoic acid (EPA), a polyunsaturated fatty acid from the omega 3 family, is also able to improve insulin sensitivity and to reduce weight gain. Moreover, EPA is able to increase apelin expression in the adipose tissue. As apelin exerts beneficial metabolic effects in the muscle, we studied the regulation of the muscle apelin/APJ system by EPA, in mice fed with a high fat diet supplemented with EPA (3. 6% of total lipids). This diet, after 10 weeks, prevented the development of obesity, glucose intolerance, alterations in muscle metabolism, and increased apelin and APJ muscle expression. In vitro, EPA induced apelin expression but also its secretion, suggesting that apelin could be a myokine, and a potential mediator of EPA's beneficial effects in insulin resistance

Full textInsulin resistance and obesity are areas of intense research. Skeletal muscle, as the major site of insulin-mediated glucose uptake, is major target in the search for solutions against this metabolic dysfunction. The interaction between adipose tissue and skeletal muscle, through myokines and adipokines, plays a role in insulin-mediated glucose uptake. The subject of this thesis focuses on the study of irisin and two adipokines, leptin and adiponectin, and their relationship with insulin resistance, in middle aged non-diabetic men. Results showed that high levels of circulating irisin are associated to a deteriorated metabolic profile, and that an adipose tissue health secretion profile is a more powerful predictor of insulin sensitivity than abdominal obesity.

Full textLa obesidad es una situación de exceso de masa grasa corporal que puede conducir al síndrome metabólico (SM). Omentin se produce y es secretada por el TAV y puede tener un papel antiinflamatorio importante en estados pro-inflamatorios. La disminución de los niveles circulantes y de la expresión génica de vaspina se asocia a empeoramiento de la diabetes y la pérdida de peso corporal. Simultaneamente al aumento de la incidencia de la obesidad y la diabetes, aumenta la prevalencia de la hepatopatía grasa no alcohólica (HGNA). Dado que la biopsia hepática es una técnica invasiva, existe un interés en el desarrollo de biomarcadores no invasivos para la identificación de esteatohepatitis. Los objetivos fueron analizar los niveles circulantes de omentin y vaspina, su expresión génica en el tejido adiposo en mujeres con obesidad mórbida frente a mujeres con peso normal. Se examinó su asociación con las variables bioquímicas así como el uso clínico de los niveles circulantes de omentin y vaspina como potenciales biomarcadores de la presencia de la HGNA. Primero, se analizaron los niveles circulantes y la expresión génica de vaspina y omentin en sujetos con normopeso y obesidad mórbida (OM). Después, se analizaron 40 muestras de hígado de las mujeres con OM. Los resultados mostraron disminución de los niveles de omentin en la OM, presentando correlación inversa con los parámetros glucémicos y el SM. La expresión de Omentin estaba disminuida en la OM. En contraste, los niveles séricos de vaspina en los OM no fueron diferentes de los controles, con una correlación inversa con los niveles de lipocalina-2 e IL6. La expresión de vaspina fue mayor en los OM. En cuanto a la HGNA, demostramos un aumento de los niveles circulantes de omentin en los pacientes con EHNA respecto a aquellos con ES. El rendimiento de los niveles de omentin para el diagnóstico de EHNA mostró una excelente AUROC. Las conclusiones son que omentin parece ejercer un efecto protector frente la obesidad, mientras que sus niveles circulantes aumentan paradójicamente en los pacientes con EHNA.
Obesity is a situacion with excess of body fat mass that can lead to metabolic syndrome. Omentin is produced and secreted by VAT and may have an important anti-inflammatory role in pro-inflammatory states. Decreases in vaspin expression and plasma levels accompany worsening of diabetes and body weight loss. In parallel with increased incidence of obesity and type 2 diabetes, the prevalence of non-alcoholic fatty liver disease (NAFLD) is growing worldwide. Because liver biopsy is an invasive procedure there is strong interest in developing non-invasive biomarkers for identifying steatohepatitis in NAFLD. The main objectives of this doctoral thesis were to analyze omentin and vaspin gene expression in VAT and SAT as well as circulating levels in a group of morbidly obese women versus normal-weight control women and its associations with the clinical-biochemical variables as well as the clinical use of circulating omentin and vaspin levels as biomarkers for the presence of NAFLD. First, we analyzed the circulating levels and gene expression of vaspin and omentin in normal-weight and morbidly obese (MO) subjects. Then, we analyzed 40 liver samples from MO women. We showed lower circulating omentin levels in the MO, correlating inversely with glucidic metabolism parameters and also with MetS. Omentin mRNA expression in VAT was reduced in MO. In contrast, serum vaspin levels in the MO were not significantly different from those in the controls, correlating inversely with lipocalin-2 and interleukin-6 levels. Vaspin mRNA expression was significantly higher in the MO. Regarding NAFLD, we revealed increased circulating omentin levels in NASH patients in comparison with SS. The performance of omentin in diagnosing NASH showed an excellent AUROC. In conclusion, the main findings of this doctoral thesis are that omentin appears to exert a protective effect against obesity, whereas circulating omentin levels are paradoxically increased in patients with NASH.

Uncontrolled, systemic inflammation coupled to obesity is associated with increased morbidity and mortality of cardiovascular disease. As a consequence of adipose tissue expansion, hypoxia ensues resulting in inflammation, and the release of various factors to restore sufficient blood flow to the tissue. However, this is often inadequate and does not result in proper tissue oxygenation. Currently little is known about the potential for endogenously expressed immuno-modulatory cytokines to attenuate inflammation and also provide pro-angiogenic effects. Interleukin-19 is uniquely immuno-modulatory, pro-angiogenic and is expressed in adipose tissue. There is no known mechanism to explain the role of IL-19 in adipose tissue expansion. We hypothesize that IL-19 acts as a novel adipokine whose expression in inflamed adipose tissue promotes a compensatory, immuno-modulatory effect and is a counter-regulatory response to inflammatory stimuli. We report that IL-19 is expressed in adipose tissue at both the transcript and protein level and its expression is increased in inflamed visceral adipose tissue but not subcutaneous adipose tissue. Utilizing Il19-/- knockout mice, we found the loss of IL-19 leads to a metabolic phenotype characterized by reduced glucose and insulin tolerance, a reduction in protective gene expression with increased pro-inflammatory factors, increased adipose tissue hypoxia and fibrosis, decreased adipose tissue vessel density and increased adipocyte hypertrophy both in response to standard chow diet and chronic high fat diet. In cultured adipocytes the addition of IL-19 leads to increased metabolically protective factors while also increasing glucose uptake. Acute treatment with IL-19 reduced glucose and insulin intolerance in obese wild-type mice. These data suggest that IL-19 presents a novel therapeutic opportunity in that IL-19 can effectively allow adipose tissue expansion without concomitant inflammation and insulin insensitivity. Interleukin Enhancer-binding Factor 3 (ILF3), an RNA-binding protein, is best known for its role in innate immunity by participation in cellular anti-viral responses. A role for ILF3 in angiogenesis is unreported. Our working hypothesis is that ILF3 promotes angiogenesis through cytokine-inducible mRNA stabilization of pro-angiogenic transcripts. ILF3 expression in CD31+ capillaries of hypoxic cardiac tissue was detected by immunohistochemistry. Pro-angiogenic stimuli induce ILF3 mRNA and protein expression in cultured human coronary artery endothelial cells (hEC). Angiogenic indices including proliferation, migration and tube formation are all significantly reduced in hEC when ILF3 is knocked down using siRNA, but are significantly increased when ILF3 is overexpressed using adenovirus. Protein and mRNA abundance of several angiogenic factors including CXCL1, VEGF, and IL-8 are decreased when ILF3 is knocked down by siRNA. These factors are increased when ILF3 is overexpressed by adenovirus. ILF3 is phosphorylated and translocates from the nucleus to the cytoplasm in response to angiogenic stimuli. Pro-angiogenic transcripts containing adenine and uridine-rich (AU-rich) elements (AREs) were bound to ILF3 determined using RNA immunoprecipitation. ILF3 stabilizes pro-angiogenic transcripts including VEGF, CXCL1, and IL-8 in hEC. Together these data suggest that in endothelial cells, the RNA stability protein, ILF3, plays a novel and central role in angiogenesis.

Full textObesity is associated with a higher risk of atherosclerotic cardiovascular pathologies and accordingly entails a great deal of morbidity and mortality. Central to obesity is the accumulation of large amounts of white adipose tissue, which inappropriately secretes bioactive molecules involved in a state of local and systemic low grade inflammation as well as metabolic anomalies. These molecules are the adipokines including leptin, resistin and adiponectin. An abdominal aortic aneurysm (AAA) is a localized and permanent aortic dilation, exceeding 50% of the adjacent normal aortic wall diameter. AAA has long been considered an atherosclerotic complication, a theory which has recently been challenged. Only a few studies have evaluated the prevalence and risk factors of AAA in coronary artery disease (CAD) patients. In the first part of our work, we dealt with 217 patients undergoing coronary artery bypass grafting for severe CAD. In men aged less than 75 years with a smoking history, AAA prevalence reached 24% if they had concomitant peripheral artery disease or carotid artery stenosis, vs 4.4% in the absence of either condition. AAA screening is only recommended in men, aged 65 to 75 years, with a history of smoking. Na data are available on the need for AAA screening among CAD patients. The second part of our work is a review on the prevalence and risk factors of AAA in CAD patients. Despite a limited number of studies, AAA seems to be more prevalent among CAD patients compared to the global population. Only some traditional atherosclerosis risk factors remain significantly associated with AAA (smoking, age, atherosclerosis of other vascular beds). Accordingly, AAA may not be pressed into a simple scheme as just an atherosclerotic complication. The benefit of AAA screening in this specific sub-population needs to be further assessed. Both AAA and atherosclerosis share chronic arterial wall inflammation. Hence, in the 3rd part of the current work, we measured circulating levels of the 3 main adipokines (leptin, resistin and adiponectin) and assessed their relationship with the presence of AAA among our precited severe CAD male patients. Only serum resistin levels were independently associated with AAA, and correlated with infra renal aortic diameter. This correlation disappeared in the AAA range. Eventually, resistin could be associated with AAA pathogenesis, independently of its implication in atherosclerosis – related inflammation. The fourth and final part of our work has acknowledged the role of leptin in the development of atherosclerotic carotid artery stenosis. We included 146 patients scheduled for carotid endarterectomy for asymptomatic versus symptomatic carotid artery stenosis. We reported, for the first time, that serum and intra–plaque leptin levels were significantly lower in symptomatic patients compared to asymptomatic patients. This result was confirmed by multivariate analysis. Circulating and intra plaque levels were positively correlated to a stable plaque phenotype (high collagen/macrophage ratio). In vitro, leptin induced an initial migratory response on vascular smooth muscle cells (VSMC) at the concentration range of 0 to 20 ng/mL, followed by a proliferative response (20 to 75 ng/mL). At higher concentrations (100 ng/mL), leptin brought about VSMC apoptosis. Leptin could thus play an active role in carotid plaque stabilization, via its effects on VSMC. Several conclusions can be drawn. AAA is not a mere atherosclerotic complication. On one side, resistin could actively influence the development and progression of AAA. On the opposite side, leptin could promote atherosclerotic plaque stabilization, via its effects on VSMC migration and proliferation

Full textPurpose: Over the last years, the situation of animal health concerning dairy cows has developed worldwide in an adverse way. Most important indicator is the shortened useful life of approx. 2.4 years. The fat mobilization syndrome plays a dominant role in this process. Apparently, fatty tissue does not only serve as a mere energy reservoir, but also as an endocrin organ with metabolic activity. Researches on humans and mice have shown fatty tissue to react on metabolic and hormonal stimuli in different ways, depending on its body localization. There are dues to anticipate, similar differences in cattle. Objectives: In order to better characterize the attributes of bovine fatty tissue and its purpose in metabolism, the present study aims examine basically the expression of mRNA in selected genes which are important for lipid metabolism in bovine fatty tissue of different localizations in healthy cattle. Methods and material: Samples where taken from twelve carcasses of healthy dairy cows slaughtered for reason of difficult milking or infertility directly after killing. Fatty tissue was taken from omentum major, kidney capsula, caudal pelvis area (retroperiteonal fat), hip area (subcutaneous fat), and cardiac base. It was instantly quick-freezed in liquid nitrogen, put on dry ice while transporting, and stored at -70°C until analysis. The expression of mRNA of different genes (hormone-sensitive lipase (HSL), lipoproteine lipase (LPL), fatty acid synthase (FASN), fatty acid binding proteine (FABP3,4 and 5), retinol binding proteine 4 (RBP4), adiponectine, glucose transporter 4 (GLUT4), leptin, interleukin-6 (IL-6), and tumor necrosis factor a (TNFα) was measured by means of a quantitative real-time (RT)-PCR. Results: The mRNA-expressions of all these different genes except IL-6 and FABP3 were detected in bovine fatty tissue. The differences of mRNA-expression between sample localization were not statistically significant. RBP4 was excepted, which mRNA showed a significantly higher expression in pericardial fat than in subcutaneous and omental fat, respectively. The correlation between mRNA-expressions of subcutaneous, omental, pericardial and perirenal fat was significant. Conclusions: The mRNA-expression of examined genes being involved in fatty tissue metabolism, were detected in healthy cattle, but were not significantly different, except RBP4. Significantly positive correlations between subcutaneous, omental, perirenal and pericardial localization and consistent expression indicate an integrative metabolism of the whole body. Compared to results of the human medicine only few analogies (HSL, LPL, GLUT4, TNF) were found. Further studies comparing healthy and diseased cattle will have to prove, if possible displacements of the mRNA-level can indicate the fat mobilization syndrome being present

Full textOsteoarthritis (OA) is a degenerative joint disease and represents one of the most frequent and disabling disease. There is a positive association between obesity and OA, and not only for knee joints but also for non-weight-bearing joints suggesting that adipose-derived proteins, namely adipokines, may be some keys factors in OA pathophysiology. First, we found that leptin and adiponectin expression and their receptor evolves in an opposite way and depend on differenciation stage of chondrocyte. The production of adipokines were then compared according to adipose tissue and some differences were found between, the infrapatellat fat pad and subcutaneous adipose tissue. After this work, we aimed to further characterize the role of leptin and adiponectin in OA. Adiponectin production by chondrocytes increases when cartilage is damaged and seems to be directly related with MMP-13 and TGF-[bêta] expression. AdipoR1 expression is associated with the expression of matrix components and with Sox9, a transcription factor involved in their synthesis. Adiponectin treatment confirms data in OA patient, that is adiponectin can induce TGF-[bêta] and MMP-13. Then, we showed obesity influences the chondrocyte responsivness to leptin. This adipokine seems to protect cartilage collected from normal or overweight patient by stimulating IGF-1, type 2 collagen and TIMP-2 expression while leptin increases MMP-13 expression for obese patients. Finally, experimental OA in Zucker rat deficient in leptin receptor, showed the protective effect of leptin on cartilage and on subchondral bone

Full textTiivistelmä Lihavuus on kasvava ongelma länsimaissa. Lihavuudella on todettu olevan yhteyttä lukuisiin kroonisiin sairauksiin, kuten diabetekseen ja sydän- ja verisuonitautiin. Ei-alkoholiperäinen rasvamaksa aiheutuu rasvan kertymisestä maksaan. Tilan on todettu liittyvän läheisesti vaikeisiin aineenvaihdunnan häiriöihin. Ei-alkoholiperäinen rasvamaksa vaihtelee vakavuusasteeltaan poikkeavasta rasvan kertymisestä tulehdukseen, joka voi edelleen johtaa kirroosiin ja maksan toiminnan pettämiseen. Adiponektiini on pääasiassa rasvakudoksen erittämä hormoni, jolla on tulehdusta hillitseviä, ateroskleroosilta suojaavia ja insuliinia herkistäviä ominaisuuksia. Rasvakudoksen tulehdustila myötävaikuttaa alentuneeseen adiponektiinipitoisuuteen, joka voi johtaa vaikeutuneisiin aineenvaihdunnan häiriöihin. Adiponektiinin epäillään olevan välittäjäaine lihavuuden ja rasvamaksan ja lihaksensisäisen rasvan välillä. Rasvamaksan ja kardiovaskulaarisairauksien välillä saattaa olla yhteys. Sydän- ja verisuonisairaudet aiheuttavat lähes puolet kuolemista Suomessa. Perinteisiä kardiovaskulaaritaudin riskitekijöitä ovat ikä, sukupuoli, tupakointi, korkea LDL-kolesteroli, korkea verenpaine ja diabetes. Tutkimuksemme tavoitteena oli selvittää maksan ja lihaksen rasvan kertymiseen myötävaikuttavia tekijöitä sekä rasvamaksan vaikutusta riskiin sairastua sydän- ja verisuonisairauksiin. Tutkimuksessa havaittiin, että lihavuuteen liittyvistä hormoneista adiponektiini oli vahvin itsenäinen myötävaikuttaja rasvamaksan kehittymisessä. Plasman alentunut adiponektiinipitoisuus yhdistyi kasvaneeseen lihassolun kokoon riippumatta henkilöiden rasvakudoksen määrästä. Seurantatutkimuksen mukaan vaikeasti rasvoittunut maksa lisäsi riskiä sairastua kardiovaskulaaritautiin, ennusti yleistä kuolemanriskiä ja kuolemaa kardiovaskulaaritautiin. Insuliiniherkkyydellä näytti olevan merkittävä rooli sydän- ja verisuonitautitapahtumissa. Tutkimus osoittaa, että adiponektiinillä saattaa olla keskeinen rooli rasvan kertymisessä maksaan ja lihakseen. Adiponektiini voi olla keskeinen tutkimuskohde kehiteltäessä hoitomuotoja ja ehkäisymenetelmiä rasvakudoksen ulkopuolisen rasvan kertymiseen. Rasvamaksan rooli sairaalahoitoon tai kuolemaan johtavissa ateroskleroottisissa tapahtumissa on ilmeinen

Full textObesity is now considered, firstly, as a risk factor for developing breast cancer in postmenopausal women and, secondly, as a risk factor for mortality in response to this pathology. Among the various hypotheses to explain the link between obesity and breast cancer, it is suggested that the adipocyte secretions (ie adipokines), whose plasma levels are known to be modulated in obesity are important. The objective of this work was therefore to assess the overall impact of adipocyte secretions and adipokines of interest to better understand the potential involvement of adipocyte tumor microenvironment in mammary carcinogenesis. In the first part, in order to situate the protein expression of several adipokines of interest in the complex disturbances involving the tumor cell, we have related the expression of these adipokines together and with that of more classical biomarkers of breast cancer (estrogen and progesterone receptor, Bax, Bcl2, Ki67...). For this, we compared, on mammary tumor and normal samples, the expression of leptin, adiponectin and zinc-α2-glycoprotein (ZAG). Cancerous tissue or normal tissue surrounding the tumor express leptin and ZAG and, more weakly, adiponectin, whereas expression of leptin and ZAG is not found in healthy tissue from women without disease. Furthermore, the expression of ZAG and leptin is positively correlated with that of the estrogen receptor, suggesting that there is a close connection between the adipokine and estrogen pathways. In the second part, we evaluated in vitro, on the one hand, the role of overall adipocyte secretions, through the establishment of an original model of "three-dimensional dermis fat" epithelialized in the presence of mammary cells, tumor or fibrocystic, and,on the other hand, the impact of interest adipokines (leptin and ZAG), on different lines of breast cancer cells. We have shown that there is a reciprocal dialogue between the adipose microenvironment and breast cancer cells, promoting tumor growth. Wealso found that leptin and ZAG exert proliferative and anti-apoptotic effects. In the third part, we try to understand the fact that obesity increases the risk of mortality from breast cancer, by issuing two additional assumptions :i) there may be a less effective treatment in situation of obesity related to an interference with some adipokines, and ii) there may be an increased risk of metastasis due to an influence of adipokines on the angiogenic process. Thus, in vitro, we showed that leptin decreases the efficacy of several cancer treatments and increases the angiogenic process and tumor invasion, especially when leptin is used at concentrations reflecting plasma impregnation in a situation of obesity, while adiponectin inhibits angiogenesis, particularly for concentrations reflecting impregnation in plasma in physiological situation. Our results suggest that adipocyte secretions are involved in regulating of breast cancer development and suggest promising ways for targeting adipokines in the prevention and / or treatment of breast cancer pathology, especially in case of overload weight
