BACKGROUND: Excess fat content in chickens has a negative impact on poultry production. The discovery of QTL associated with fat deposition in the carcass allows the identification of positional candidate genes (PCGs) that might regulate fat deposition and be useful for selection against excess fat content in chicken's carcass. This study aimed to estimate genomic heritability coefficients and to identify QTLs and PCGs for abdominal fat (ABF) and skin (SKIN) traits in a broiler chicken population, originated from the White Plymouth Rock and White Cornish breeds...

BACKGROUND: Adiponectin (ADPN) prevents the development/recurrence of cardiovascular events via its anti-atherogenic effects. However, few long-term studies have examined the changes in serum ADPN levels and arterial calcification seen in renal allograft recipients. SUBJECTS AND METHODS: The effects of the serum ADPN level on arterial calcification were examined in 51 Japanese renal allograft recipients. Abdominal aorta calcification was evaluated on computed tomography using the aortic calcification area index (ACAI)...

Two structurally novel series of chalcone derivatives were designed and synthesized as potential agents against type 2 diabetes. As a result of the antidiabetic biological evaluation in streptozotocin (STZ) induced type 2 diabetes animal model, 13e, 13g and 19f showed more significant reduction in serum Glu, TG, TC levels by contrast to the positive control AdipoRon. In addition to upregulating the expression of AdipoR1 and AdipoR2, 13e and 19f treatment also increased expression of AMPK and PPAR-α. Taken together, these results suggested that 13e and 19f might be a promising compounds for type 2 diabetes treatment...

BACKGROUND: The role of adopokines in adrenal tumors' hormonal activity remains unclear. Obesity may induce arterial hypertension, disorders of carbohydrate metabolism, and is a risk factor of cardiovascular disease. In patients with subclinical hormone secretion by the adrenal cortex or medulla the risk of metabolic disease is increased. OBJECTIVE: Authors of this retrospective study selected 78 patients with subclinical hormone secretion out of all adrenal incidentaloma patients hospitalized in the Department of Endocrinology and Internal Medicine between 1995 and 2014...

Adiponectin, an adipocyte-derived circulating protein, accumulates in vasculature, heart, and skeletal muscles through interaction with a unique glycosylphosphatidylinositol-anchored cadherin, T-cadherin. Recent studies have demonstrated that such accumulation is essential for adiponectin-mediated cardiovascular protection. Here, we demonstrate that the adiponectin/T-cadherin system enhances exosome biogenesis and secretion, leading to the decrease of cellular ceramides. Adiponectin accumulated inside multivesicular bodies, the site of exosome generation, in cultured cells and in vivo aorta, and also in exosomes in conditioned media and in blood, together with T-cadherin...

The expression of adiponectin receptors AdipoR1 and AdipoR2 has been reported in the human ovary and ovarian cancer tissues. Moreover, adiponectin has been reported to act as an anti-tumor factor by inhibiting cancer cell proliferation. Thus, we investigate whether adiponectin and its receptors influence ovarian cancer development. In the present study, we found that adiponectin was not expressed in the granulosa cell line (COV434), and epithelial ovarian cancer cell lines (OVCAR-3, SKOV-3, and Caov-3). Additionally, we found that AdipoR1 and AdipoR2 expression is lower in epithelial ovarian cancer cells than in granulosa tumor cells...

BACKGROUND: Adiponectin (ADN) is an adipokine derived from adipocytes. It binds to adiponectin receptor 1 and 2 (AdipoR1 and R2) to exert its function in regulating whole-body energy homeostasis and inflammatory responses. However, the role of ADN-AdipoR1 signaling in intestinal inflammation is controversial, and its role in the regulation of neutrophils is still unclear. Our goal was to clarify the role of AdipoR1 signaling in colitis and the effects on neutrophils. METHODS: We generated porcine AdipoR1 transgenic mice (pAdipoR1 mice) and induced murine colitis using dextran sulfate sodium (DSS) to study the potential role of AdipoR1 in inflammatory bowel disease...

Background The development of an effective treatment for type 2 diabetes mellitus is urgently needed. This study aimed to investigate the role of micro RNA (miR)-323-3p in regulating the expression of adiponectin receptor 1 (AdipoR1), as well as the insulin secretion and cell function of pancreatic MIN6 β-cells. Methods MIN6 cells were treated with miR-323-3p mimics or inhibitors, and the effects on cell growth, proliferation, mitosis, and insulin secretion were studied. The expression levels of sirtuin-1 (SIRT-1) and AMP-activated protein kinase (AMPK) genes were also assessed...

Adiponectin is an important adipocyte-derived plasma protein that has beneficial effects on cardio- and cerebrovascular diseases. A low level of plasma Adiponectin is associated with increased mortality post ischemic stroke; however, little is known about the causal role of Adiponectin as well as its molecular mechanisms in neonatal hypoxia ischemia (HI). In the present study, ten-day-old rat pups were subjected to right common carotid artery ligation followed by 2.5 h hypoxia. Recombinant human Adiponectin (rh-Adiponectin) was administered intranasally 1 h post HI...

Adiponectin is an adipocyte-derived hormone with antidiabetic activities that include increasing the sensitivity of cells to insulin. Adaptor protein containing pleckstrin homology domain, phosphotyrosine-binding domain, and leucine zipper motif (APPL1) stimulates adiponectin signaling and promotes adiponectin's insulin-sensitizing effects by binding to two adiponectin receptors, AdipoR1 and AdipoR2, and the insulin receptor. In this study, we report an alternative splicing variant of APPL1 (APPL1sv) that is highly expressed in mouse liver, pancreas, and spleen tissues...

OBJECTIVE: The high molecular weight (HMW) adiponectin isoform is considered the active form of adiponectin and is linked to insulin sensitivity and the reduced risk of developing cardiovascular disease. The purpose of the first study was to determine the effects of age and sex on the plasma HMW adiponectin response to acute hyperinsulinemia, and secondly determine whether either endurance or resistance exercise training could affect this response. DESIGN AND PARTICIPANTS: Twenty-six healthy males (19-84 years) and twenty-six healthy females (18-76 years) were recruited and matched for BMI to examine the effects of sex and age on the plasma adiponectin response to a 2-hour hyperinsulinemic-euglycemic clamp...

INTRODUCTION: The novel phytohormone, osmotin, has been reported to act like mammalian adiponectin through PHO36/AdipoR1 in various in vitro and in vivo models. However, there have been no reports regarding the precise effects of osmotin on atherosclerosis. METHODS: We assessed the atheroprotective effects of osmotin on inflammatory molecules in human umbilical vein endothelial cells (HUVECs), human leukemic monocyte (THP-1) adhesion, inflammatory responses, and foam cell formation in THP-1-derived macrophages, and the migration, proliferation, and extracellular matrix expression in human aortic smooth muscle cells (HASMCs)...

Objective: It is commonly accepted that adiponectin binds to its two receptors to regulate fatty acid metabolism in adipocytes. To better understand their functions in the regulation of intramuscular adipogenesis in goats, we cloned the three genes (AdipoQ, AdipoR1 and AdipoR2) encoding these proteins and detected their mRNA distribution in different tissues. We also determined the role of AdipoQ in the adipogenic differentiation of goat skeletal muscle satellite cells (SMSCs). Methods: SMSCs were isolated using 1 mg/ml Pronase E from the longissimus dorsi muscles of 3-day-old female Nanjiang brown goats...

Maternal obesity is associated with large-for-gestational-age (LGA) neonates and programming of obesity-related cardiovascular disease in the offspring, however, the mechanisms that lead to the later are unclear. Presently, interpretations of NO-dependent changes in vascular function in LGA newborn from obese mothers are conflicting. Adiponectin improves endothelial function by increasing eNOS activity and NO production. We propose that LGAs from obese mothers present a diminished vascular response to adiponectin; thus, affecting eNOS and AMPK activation...

Adiponectin (APN) is a protein hormone that is primarily derived from adipocytes. It can also be secreted by renal cells. Hypoadiponectinemia has been documented in patients with hyperuricemia, however, whether soluble uric acid (SUA) regulates the expression of APN and APN receptor 1 (AdipoR1) in renal proximal tubule epithelial cells (PTECs) remains to be elucidated. The present study investigated the expression of APN and AdipoR1 in cultured PTECs that were exposed to SUA through immunofluorescence and western blot analysis...

Alzheimer's disease is a major neurodegenerative disease characterized by memory loss and cognitive deficits. Recently, we reported that osmotin, which is a homolog of adiponectin, improved long-term potentiation and cognitive functions in Alzheimer's disease mice. Several lines of evidence have suggested that Nogo-A and the Nogo-66 receptor 1 (NgR1), which form a complex that inhibits long-term potentiation and cognitive function, might be associated with the adiponectin receptor 1 (AdipoR1), which is a receptor for osmotin...
