Osteoblasts and adipocytes coexist in the implantation site and affect the process of titanium (Ti) osseointegration. As extracellular signal-regulated kinases 1/2 (ERK1/2) are involved in osteogenesis and adipogenesis, the aim of our study was to investigate if the effects of Ti surface topography on osteoblast and adipocyte differentiation are modulated by ERK1/2. The experiments were conducted based on the effect of the ERK1/2 inhibitor, PD98059, on mesenchymal stem cells (MSCs) grown under osteogenic and adipogenic conditions on Ti with nanotopography (Ti-Nano) or on machined Ti (Ti-Machined)...

Body fat mass is closely associated to diseases related to obesity. MicroRNAs (miRNAs, miR) are important regulatory molecules that function as post-transcriptional gene regulators of adipocyte development. In the current study, we revealed that reduced expression of miR-199a-3p in adipose tissue resulting from high fat diet (HFD)-induced obesity in mice. Overexpression of miR-199a-3p promoted adipocyte proliferation by regulating the expression of regulating factors of the cell cycle. Furthermore, miR-199a-3p blunted lipid accumulation in 3T3-L1 adipocytes...

Recent studies have shown that overexpression of tonicity-responsive enhancer binding protein (TonEBP) is associated with many inflammatory diseases, including diabetes mellitus, which causes neuroinflammation in the hippocampus as well as hepatic steatosis. However, the exact mechanism in diabetic neuroinflammation is unknown. We report that haploinsufficiency of TonEBP inhibits hepatic and hippocampal high-mobility group box-1 (HMGB1) expression in diabetic mice. Here, mice were fed a high-fat diet (HFD) for 16 weeks and received an intraperitoneal injection of 100 mg/kg streptozotocin (STZ) and followed by continued HFD feeding for an additional 4 weeks to induce hyperglycemia and hepatic steatosis...

The prevalence of obesity has been increasing in recent decades and is reaching epidemic proportions. The current options for overweight and obesity management are energy restriction and physical activity. However, compliance with these treatments is frequently poor and less successful than expected. Therefore, the scientific community is interested in active biomolecules, which may be useful in body weight management. Among them, resveratrol (3,5,4'-trihydroxy-trans-stilbene) has generated great interest as an antiobesity agent...

The extracellular matrix (ECM) is an important extracellular microenvironmental factor that regulates stem cell differentiation. The ECM is remodeled according to stem cell differentiation progression to precisely regulate the differentiation. Thus, it is expected that the matrices mimicking native ECM surrounding differentiating cells at each differentiation stage provide a favorable microenvironment to promote stem cell differentiation. However, it is difficult to prepare matrices mimicking native ECM using chemical methods because the ECM has a complicated composition...

During obesity, macrophages can infiltrate metabolic tissues, and contribute to chronic low-grade inflammation, and mediate insulin resistance and diabetes. Recent studies have elucidated the metabolic role of JAK2, a key mediator downstream of various cytokines and growth factors. Our study addresses the essential role of macrophage JAK2 in the pathogenesis to obesity-associated inflammation and insulin resistance. During high-fat diet (HFD) feeding, macrophage-specific JAK2 knockout (M-JAK2(-/-)) mice gained less body weight compared to wildtype littermate control (M-JAK2(+/+)) mice and were protected from HFD-induced systemic insulin resistance...

Stem cells respond to environmental signals that induce their differentiation to cells that make up specialized tissues and organs. Our laboratory has focused on bone marrow mesenchymal stem cells (MSCs) that supply bone osteoblasts and marrow adipocytes, an output that appears to be reciprocal. Case in point: exercise promotes osteogenesis and bone formation, and inhibits marrow adipose accrual. A mechanically induced signal pathway concentrating on preserving β-catenin also causes increased structure of the actin cytoskeleton, both of which inhibit adipogenesis...

Although bone morphogenetic protein-2 (BMP2) has demonstrated extraordinary potential in bone formation, its clinical applications require supraphysiological milligram-level doses that increase postoperative inflammation and inappropriate adipogenesis, resulting in well-documented life-threatening cervical swelling and cyst-like bone formation. Recent promising alternative biomolecular strategies are toward promoting pro-osteogenic activity of BMP2 while simultaneously suppressing its adverse effects. Here, we demonstrated that small molecular phenamil synergized osteogenesis and bone formation with BMP2 in a rat critical size mandibular defect model...

Neuropeptide Y (NPY) stimulates appetite and promotes lipid deposition. We demonstrated a differential sensitivity in the food intake response to central NPY in chicks from lines selected for low (LWS) or high (HWS) body weight, but have not reported whether such differences exist in the periphery. At 5days, LWS and HWS chicks were intraperitoneally injected with 0 (vehicle), 60, or 120μg/kg BW NPY and subcutaneous adipose tissue and plasma were collected at 1, 3, 6, 12, and 24h (n=12). NPY injection increased glycerol-3-phosphate dehydrogenase (G3PDH) activity at 1 and 3h and reduced plasma NEFAs at 1 and 12h...

Designing two-photon probes for precise labelling lipid droplet (LD) and monitoring LD dynamics in adipocytes is of great significance to understand LD homeostasis. We herein report that a luminescent metal complex LD-TPZn can specifically image LDs in adipose cells and tissue using one- or two-photon fluorescence microscopy. Importantly, LD-TPZn exhibited higher specificity to LD than commercial Nile Red and Bodipy 493/503, probably due to different cellular uptake pathways, clathrin-mediated endocytosis and non-selectively passive diffusion, respectively...

Adipocytes play a central role in maintaining metabolic homeostasis in the body. Differentiation of adipocyte precursor cells requires the transcriptional activity of peroxisome proliferator-activated receptor-γ (Pparγ) and CCAAT/enhancer binding proteins (C/Ebps). Transcriptional activity is regulated by signaling modules activated by a plethora of hormones and nutrients. Mechanistic target of rapamacin complexes (mTORC) 1 and 2 are central for the coordination of hormonal and nutritional inputs in cells and are essential for adipogenesis...

Peroxisome proliferator-activated receptor gamma (PPARγ) is a key regulator of adipogenesis. It is also a central player in energy metabolism, inflammation and immunity. As an important nuclear transcription factor, PPARγ can regulate the expression and function of genes or biological processes directly or indirectly via association with other factors and thus modulate their activities. To better understand the impact of PPARγ on the global gene expression profile, we evaluated the bioinformatic data, which revealed the changes that occurred in genes and their pathways in the absence of PPARγ...

 Peroxisome proliferator-activated receptor γ (PPARγ) antagonist is a molecular target to create drug for the treatment of not only type 2 diabetes and obesity, but also cancer. However, few rational drug design strategies and concepts are available. Here, we utilized the nuclear receptor helix12-folding inhibition hypothesis, in combination with structural biology data of our PPARγ agonist (5) complexed with the PPARγ ligand-binding domain. We found a potent phenylalkynyl amide-type PPARγ antagonist 18i, based on pinpoint structural modification of the acidic head part of 5...

Abundance and accessibility render skin-derived stem cells an attractive cell source for tissue engineering applications. Toward assessing their utility, the variability of constructs engineered from human dermis-isolated adult stem (hDIAS) cells was examined with respect to different anatomical locations (foreskin, breast, and abdominal skin), both in vitro and in a subcutaneous, athymic mouse model. All anatomical locations yielded hDIAS cells with multi-lineage differentiation potentials, though adipogenesis was not seen for foreskin-derived hDIAS cells...

Dietary flavonoids have been shown to extend the lifespan of some model organisms and may delay the onset of chronic ageing-related diseases. Mechanistically, the effects could be explained by the compounds scavenging free radicals or modulating signalling pathways. Transcription factors Nrf2, FoxO, and PPARγ possibly affect ageing by regulating stress response, adipogenesis, and insulin sensitivity. Using Hek-293 cells transfected with luciferase reporter constructs, we tested the potency of flavonoids from different subclasses (flavonols, flavones, flavanols, and isoflavones) to activate these transcription factors...

Permethrin, a type 1 pyrethroid insecticide, was previously reported to promote adipogenesis in 3T3-L1 adipocytes and insulin resistance in C2C12 muscle cells; however, the effects of permethrin exposure on glucose and lipid metabolisms in vivo remain unknown. The purpose of this study was to investigate the effects of permethrin exposure on glucose and lipid homeostasis as well as voluntary movement in female mice in response to dietary fat. We tested three doses of permethrin (50, 500, & 5000 μg/kg body weight/day) in low fat diet-fed (4% w/w of diet) and high fat diet-fed (20% w/w of diet) female C57BL/6 J mice for twelve weeks...

BACKGROUND: Hematopoietic stem cells (HSCs) promote fat graft survival by modulating its revascularization. The authors hypothesize that mobilization of HSCs by G-CSF will improve fat graft survival. Hence, we evaluated the effect of different doses of G-CSF on fat grafting. METHODS: Male 8-week-old C57 mice received high-dose G-CSF (100 μg/kg), low-dose G-CSF (10 μg/kg), and PBS (control) intraperitoneally for 7 consecutive days right after autologous fat grafting...

The three dimensional folding of mammalian genomes is cell-type specific and difficult to alter suggesting that it is an important component of gene regulation. However, given the multitude of chromatin associating factors, the mechanisms driving the co-localization of active chromosomal domains and the role of this organization in regulating the transcription program in adipocytes are not clear. Analysis of genome-wide chromosomal associations revealed cell type-specific spatial clustering of adipogenic genes in 3T3-L1 cells...
