A previous study from our group using an in vivo model demonstrated that diet induced-obesity increases the risk of gastric cancer and may prompt its growth. However, the molecular mechanisms underlying this association remain unclear and require further investigation. The aim of the present study was to investigate the potential molecular mechanisms through which obesity affects gastric cancer growth. In a subcutaneous mouse model, tumors were significantly larger in obese mice compared with non-obese and lean mice...

Gingivitis and periodontitis are common bacterial infections caused by a variety of microorganisms. Despite the microorganisms' roles as etiologic agents, inflammation-induced substances also have crucial parts in the loss of connective tissue and the supporting alveolar bone. Visfatin is a pleiotropic mediator, which acts as growth factor, cytokine, and pre-B-cell colony-enhancing factor. A positive correlation was detected between the serum/plasma levels of visfatin and inflammatory disorders such as diabetes mellitus and cardiovascular disease...

Many epidemiological studies have confirmed the relationship of obesity and psoriasis, and it is believed that obesity is an independent risk factor for its development and is associated with a worse prognosis. Furthermore, the reduction of body weight, using low-calorie diet combined with exercise, reduces the severity of psoriasis.Visceral adipose tissue is the largest endocrine organ, producing proinflammatory cytokines (TNF-α, IL-6, IL-17) and adipokines (adiponectin, omentin, chemerin). They participate in the development of dyslipidemia, insulin resistance, diabetes, and consequently of the cardiovascular diseases...

OBJECTIVE: Nicotinamide phosphoribosyltransferase (NAMPT, also referred to as pre-B cell colony-enhancing factor or visfatin) is critically required for the maintenance of cellular nicotinamide adenine dinucleotide (NAD) supply catalysing the rate-limiting step of the NAD salvage pathway. NAMPT is strongly upregulated in inflammation including IBD and counteracts an increased cellular NAD turnover mediated by NAD-depleting enzymes. These constitute an important mechanistic link between inflammatory, metabolic and transcriptional pathways and NAD metabolism...

Visfatin is a newly identified adipocytokine that plays an important role in the determination of fat traits. In this study, we investigated the characterization of visfatin and the relationship between gene expression and chicken development to provide a theoretical basis for studying visfatin functions. The main results are summarized as follows: The 1482-bp full coding sequence of the visfatin gene of silky fowl was obtained and found to encode 493 amino acids. This gene contains 26 phosphorylation sites and a conserved domain of the NAPRTase family but no signal peptide sequence...

Visfatin, which is secreted as an adipokine and cytokine, has been implicated in cancer development and progression. In this study, we investigated the NAD-producing ability of visfatin and its relationship with SIRT1 (silent information regulator 2) and p53 to clarify the role of visfatin in breast cancer. MCF-7 breast cancer cells were cultured and treated with visfatin. SIRT1 activity was assessed by measuring fluorescence intensity from fluoro-substrate peptide. To investigate the effect of visfatin on p53 acetylation, SDS-PAGE followed by western blotting was performed using specific antibodies against p53 and its acetylated form...

Adipose tissue (AT) dysfunction, characterized by loss of its homeostatic functions, is a hallmark of non-communicable diseases. It is characterized by chronic low-grade inflammation and is observed in obesity, metabolic disorders such as insulin resistance and diabetes. While classically it has been identified by increased cytokine or chemokine expression, such as increased MCP-1, RANTES, IL-6, interferon (IFN) gamma or TNFα, mechanistically, immune cell infiltration is a prominent feature of the dysfunctional AT...

BACKGROUND: Cancer cachexia is a multifactorial metabolic syndrome characterized by marked loss of adipose tissue and skeletal muscle. Fat loss from adipose tissue in cancer cachexia is partly the result of increased lipolysis. Despite the growing amount of studies focused on elucidating the mechanisms through which lipolysis-related proteins regulate the lipolytic process, there are scarce data concerning that profile in the adipose tissue of cancer cachectic patients. Considering its fundamental importance, it was our main purpose to characterize the expression of the lipolysis-related proteins in the white adipose tissue of cachectic cancer patients...

BACKGROUND: Dry immersion (DI), a ground-based model of microgravity previously used in Russia, has been recently implemented in France. The aim of this study was to analyze early events in a short-term DI model in which all conditions are met to investigate who is first challenged from osteo- or adipo-kines and to what extent they are associated to insulin-regulating hormones. METHODS: Twelve healthy men were submitted to a 3-day DI. Fasting blood was collected during pre-immersion phase for the determination of the baseline data collection (BDC), daily during DI (DI24h, DI48H and DI72h), then after recovery (R+3h and R+24h)...

Musculoskeletal disorders (MSDs) are the most frequent cause of disability in Europe. Reduced mobility and quality of life of the patients are often associated with pain due to chronic inflammation. The inflammatory process, accompanied by a destruction of the cartilage and bone tissue, is discussed as a result of (A) the infiltration of immune cells into the joints, (B) an altered homeostasis of the joint cavity (synovium) with a critical role of bone remodeling cells, and (C) release of inflammatory factors including adipokines in the arthritic joint...

Development of type 2 diabetes has been linked to β-cell failure coupled with insulin resistance and obesity. Adipose tissue, known as the fat store, secretes a number of hormones and proteins collectively termed adipokines some of which regulate insulin sensitivity. Dysregulation in the secretion of adipokines has been linked to insulin resistance and type 2 diabetes. In this review, we summarized evidence of the role of adipokines with focus on leptin, adiponectin, adipsin, visfatin and apelin in the pathogenesis of type 2 diabetes and discussed the potential of saponins to modify the ill-regulated adipokines secretions, which could promote the use of this class of phytochemicals as potential antidiabetics agents...
