Identification of ITGBL1: A Novel Regulator of Adipogenesis
… are formed from their progenitor cells (the preadipocyte) when the body has a need to store excess lipid. It has been shown that the pathological expansion of white adipose tissue (WAT) leads to insulin resistance and cardiovascular disease. In spite of this clear observation, the mechanisms …

Cellular and Molecular Mechanisms Governing Intramuscular Fat Development and Growth in Cattle
… stage of adipose progenitor cells, and origin of preadipocytes. In addition, I tested the hypothesis that the delayed development and slower growth of IMF is in part due to inhibition by signaling proteins secreted by the surrounding muscle tissue. I conducted four studies. In the first study, I …

Role of appetite-regulating peptides in adipose physiology in broiler chicks
… was thus to evaluate effects of NPY on chick preadipocyte proliferation and differentiation. Preadipocytes were treated with NPY and gene expression and cellular proliferation were evaluated. Cells were also treated with NPY during differentiation and harvested during the later stages. With …

Role of SMAD2 and SMAD3 on Adipose Tissue Development and Function
… including activins, which regulate critical preadipocyte and mature adipocyte functions. Previous studies have demonstrated that Smad2 global knockout mice exhibit embryonic lethality, whereas global loss of Smad3 protects mice against diet-induced obesity and the direct contributions of …

Overcoming wound healing complications following radiotherapy in human breast dermal fibroblasts, through the influence of preadipocytes from the stromal vascular fraction
… by immunocytochemistry and compared to human preadipocytes sourced commercially. The secretion of FGF, adiponectin and VEGF by the preadipocyte and the SVF mesenchymal cells was compared and the ability of their secretome to modulate dermal fibroblast proliferation, metabolism and migration …

Characterisation of 11beta hydroxysteroid dehydrogenase 1 in ocular and orbital tissues
… conjunctival fibroblast) and orbital (orbital preadipocyte) cells. The data therefore emphasises the putative role of 11β-HSDs in the ocular and orbital microenvronment.

Hedgehog Signaling Plays a Conserved Role in Inhibiting Fat Formation
… the stage of terminal differentiation. In 3T3-L1 preadipocyte cell line, addition of recombinant murine sonic Hh (Shh) potently inhibited adipogenic differentiation dose-dependently, resulting in decreased intracellular triglyceride accumulation and reduced mRNA levels of established adipogenic …

The impact of whey protein isolate on energy balance regulation
… LPA5 is a novel candidate in regulating of preadipocyte growth and differentiation, and may mediate dietary protein effects on adipose tissue.

Assessment of blue whiting protein hydrolysate bioactivities using cell culture models
… w/v dw) reduced triglyceride accumulation during preadipocyte differentiation (p<0.05), however none of the hydrolysates hydrolysed triglycerides in fully mature adipocytes. Interestingly, after SGID, all hydrolysates reduced triglyceride accumulation during differentiation and all except one …

The role of Ad-36 and its E4orf-1 protein in modulating glycemic control
… are modulated by Ad36. In vitro, Ad36 increased preadipocyte differentiation, de-novo lipogenesis, and fat oxidation. Ad36 increased the proportion of small adipocytes in mice on a chow diet, whereas in HF-fed mice, Ad36 increased the proportion of large adipocytes. Adipose tissue macrophage …

Bioexploration of wild Alaskan berries: From field screening to functional food
… and obesity. R. spectabilis samples increased preadipocyte-factor-1 levels by 82% over control, and proanthocyanidin-rich fractions from multiple species reduced lipid accumulation in 3T3-L1 adipocytes. Furthermore, extracts of V. uliginosum and E. nigrum (Point Hope) reduced serum glucose …

A Human Pluripotent Stem Cell-Derived Model for the Investigation of Thermogenic Adipocyte Development and Function
… mice affects the differentiation of murine brown preadipocytes. I show that contrary to hPSCs, 3D culture did not improve murine brown preadipocyte differentiation, although a functional improvement was observed. Compared to lean ECM, obese ECM impaired BA differentiation and function.

Mechanistic Investigation of Genotype-Phenotype Correlations in PIK3R1-Related Diseases
… in insulin-responsive cell types, 3T3-L1 preadipocyte models with conditional overexpression of p85$\alpha$ Y657X or p85$\alpha$ R649W were generated. Doxycycline-induced overexpression of mutant p85$\alpha$ attenuated insulin-stimulated Akt phosphorylation due to reduced …

Neurological - Molecular Interface in Food Intake and Metabolism in Birds and Mammals
… in any avian species. By exposing chicken preadipocytes to different concentration of NPY, we found that NPY enhances both proliferation and differentiation and thus appears to play a major role in chicken adipogenesis, an effect that has not yet been reported, to our knowledge. In the body …

Investigating Invadolysin's activity: discerning mechanism and cellular roles
… expression of PPARγ. I used SGBS cells, a human preadipocyte cell line to study the role of invadolysin in adipogenesis. Increase in protein levels of invadolysin during adipogenesis indicates a potential role of invadolysin in adipogenesis. Invadolysin has a predicted N-terminal signal sequence …

Understanding C/EBPbeta LAP/LIP Transcriptional and Adipogenic Potential Through Regulation by HDAC1 and GCN5
The CCAAT/Enhancer Binding Protein Beta (C/EBPβ) is part of the leucine zipper family of transcription factors and is involved in a myriad of processes including cellular proliferation and differentiation. C/EBPβ is expressed as three isoforms (LAP*, LAP, LIP), translated from a single mRNA by a …

Comparative study of gene expression during the differentiation of white and brown preadipocytes
Einleitung Säugetiere haben zwei verschiedene Arten von Fettgewebe: das weiße Fettgewebe, welches vorwiegend zur Lipidspeicherung dient, und das braune Fettgewebe, welches sich durch seine Fähigkeit zur zitterfreien Thermogenese auszeichnet. Weiße und braune Adipozyten sind beide mesodermalen …
