Purpose: The purpose of this study was to characterize the secretion profile of induced pluripotent stem cell-derived retinal pigment epithelium (iPS-RPE) during wound healing. iPS-RPE was used to develop an in vitro wound healing model. We hypothesized that iPS-RPE secretes cytokines and growth factors which act in an autocrine manner to promote migration and proliferation of cells during wound healing. Methods: iPS-RPE was grown in transwells until fully confluent and pigmented...

While physical hyperactivity represents a frequent symptom of anorexia nervosa and may have a deleterious impact on the course of the disease, the underlying mechanisms are poorly understood. Since several food intake-regulatory hormones affect physical activity, the aim of the study was to investigate the association of physical activity with novel candidate hormones (kisspeptin, ghrelin, oxyntomodulin, orexin-A, FGF-21, R-spondin-1) possibly involved in patients with anorexia nervosa. Associations with psychometric parameters and body composition were also assessed...

Keratocytes of the corneal limbal stroma can derive populations of mesenchymal stem cells (MSC) when expanded in vitro. However, once a corneal MSC (cMSC) phenotype is achieved, regaining the keratocyte phenotype can be challenging, and there is no standardised differentiation medium. Here, we investigated the transition of keratocytes to cMSC and compared different supplements in their ability to return cMSC to a keratocyte phenotype. Immunofluorescence and RT-qPCR demonstrated in vivo keratocyte expression of ALDH3A1, CD34 and keratocan, but not any of the typical MSC markers (CD73, CD90, CD105)...

Several fibroblast growth factor (FGF) isoforms act to stimulate epithelial-mesenchymal transition (EMT) during cancer progression. FGF4 and FGF7 are two ligands of FGF receptor 2 (FGFR2). Using two lung adenocarcinoma (ADC) cell lines, A549 and H1299, we showed that FGF4, but not FGF7, altered cell morphology, promoted EMT-associated protein expression, and enhanced cell proliferation, migration/invasion and colony initiation. In addition, FGF4 increased store-operated calcium entry (SOCE) and expression of the calcium signal-associated protein Orai1...

Phytase hydrolyzes phytate rendering phosphorus available for intestinal absorption, while systemic neutralization of fibroblast growth factor 23 (FGF-23), using anti-FGF-23 antibody, has been shown to increase phosphate retention. Hence, neutralization of FGF-23 should be additive with phytase in reducing dietary non-phytate phosphorus (nPP) needs in chickens fed plant-based diets rich in phytic acid. This study was designed to test the additive effects of maternally derived anti-FGF-23 antibody and dietary phytase on the performance of chicks fed a low nPP diet from one to 14 d...

Given the high prevalence and rising incidence of non-alcoholic fatty liver disease (NAFLD), the absence of approved therapies is striking. Although the mainstay of treatment of NAFLD is weight loss, it is hard to maintain, prompting the need for pharmacotherapy as well. A greater understanding of disease pathogenesis in recent years was followed by development of new classes of medications, as well as potential repurposing of currently available agents. NAFLD therapies target four main pathways. The dominant approach is targeting hepatic fat accumulation and the resultant metabolic stress...

The aim of this study is to explore a new method-high dose starting and low dose maintaining for PEGylated Fibroblast growth factor 21 (pFGF-21) treatment. Db/db mice were initially treated with pFGF-21 of high dose, then treated with pFGF-21 of low doses. The mice were treated with pFGF-21 at initial dose of 1.0mg/kg for 14days, then treated with pFGF-21 at maintenance doses of 0.125/0.250/0.375/0.500mg/kg for 30days. The hypoglycemic and hypolipidemic effects of pFGF-21 of different maintenance doses were compared...

BACKGROUND: Angiogenesis is an essential process in endometriosis disease progression. Earlier, we demonstrated that anti-angiogenic peptide, ABT-898 prevents neoangiogenesis of human endometriotic lesions in a xenograft mouse model. Since angiogenesis is essential for normal ovarian and uterine function, we evaluated effects of ABT-898 on normal female reproductive processes in mice. METHODS: Cycling female C57BL/6N mice were dosed with ABT-898 (100 mg/kg) or 5 % dextrose control for 21 consecutive days to cover multiple estrous cycles (average estrous cycle 4 to 5 days in mice)...

Fibroblast growth factor (FGF)2/basic FGF is a member of the fibroblast growth factor family. Its function in skin wound healing has been well-characterized. However, the function of other FGFs in skin tissues remains to be elucidated. In the present study, FGF expression patterns in heart, liver, skin and kidney tissues were analyzed. Notably, in contrast to other tissues, only four FGFs, FGF2, 7, 10 and 21, were dominant in the skin. To examine FGF function in the wound healing process, mouse NIH3T3 fibroblast cells were treated with FGF2, FGF10 and FGF21, and cell migration was monitored...

Fibroblast growth factor 21 (FGF21) is an endocrine hormone which exerts beneficial effects on metabolic regulation in obese and diabetic models. However, the effect of FGF21 on cognition in obese-insulin resistant rats has not been investigated. We hypothesized that FGF21 prevented cognitive decline in obese-insulin resistant rats by improving hippocampal synaptic plasticity, dendritic spine density, brain mitochondrial function and brain FGF21 signaling as well as decreasing brain cell apoptosis. Eighteen male Wistar rats were divided into two groups, and received either a normal diet (ND) (n=6) or a high fat diet (HFD) (n=12) for 12weeks...

One approach to the development of an artificial graft material could rely on uniform coverage of a resorbable biomaterial with bone extracellular matrix (ECM). To achieve this on the surface of poly(propylene fumarate) (PPF) scaffolds, we selected a growth factor regime of basic fibroblast growth factor (FGF-2) (5 ng/mL), platelet-derived growth factor (PDGF-BB) (40 ng/mL), and epidermal growth factor (EGF) (20 ng/mL) to stimulate proliferation of bone marrow-derived human mesenchymal stem cells (BM-hMSCs)...

C1q/TNF-related protein 1 (CTRP1) is a conserved plasma protein of the C1q family with notable metabolic and cardiovascular functions. We have previously shown that CTRP1 infusion lowers blood glucose and that transgenic mice with elevated circulating CTRP1 are protected from diet-induced obesity and insulin resistance. Here, we used a genetic loss-of-function mouse model to address the requirement of CTRP1 for metabolic homeostasis. Despite similar body weight, food intake, and energy expenditure, Ctrp1 knockout (KO) mice fed a low-fat diet developed insulin resistance and hepatic steatosis...

OBJECTIVE: Metabolic adverse effects of atypical antipsychotics (AAP) contribute significantly to increased risk of cardiovascular morbidity and mortality in patients suffering from schizophrenia. Extensive preclinical research has addressed this issue over the past years, though mechanisms underlying these adverse effects of AAP are still not understood completely. Recently, attention is drawn towards the role of adipose tissue metabolism and neurohormonal regulations. METHODS: The aim of this study was to evaluate the time-dependent effects of olanzapine depot administration at clinically relevant dosing on the regulation of energy homeostasis, glucose and lipid metabolism, gastrointestinal and adipose tissue-derived hormones involved in energy balance regulations in female Sprague-Dawley rats...

CONTEXT: Perivascular adipose tissue (PVAT) is suggested to impact on vascular cells via humoral factors, possibly contributing to endothelial dysfunction and atherosclerosis. OBJECTIVE: To address whether the hepatokine fibroblast growth factor (FGF) 21 affects the PVAT secretome. METHODS: Human perivascular (pre)adipocytes were subjected to targeted proteomics and whole-genome gene expression analysis. RESULTS: Preadipocytes, as compared to adipocytes, secreted higher amounts of inflammatory cytokines and chemokines...

INTRODUCTION: Human fibroblast growth factor 21 (FGF21) is a regulator of lipid and glucose metabolism. It is expressed in skeletal muscle, and may be a sensitive and specific marker for mitochondrial diseases and other neuromuscular disorders. METHODS: Serum FGF21 levels were determined in 71 human samples. Thirty patients with mitochondrial disease, 16 patients with myotonic dystrophy type 1 (DM1), 5 patients with facioscapulohumeral dystrophy (FSHD), and 20 healthy controls were enrolled...
