An increasing number of patients are being treated with growth hormone (GH) for the enhancement of body growth but also as an anti-aging strategy. However, the side effects of GH have been poorly defined. In this study we determined the effect of GH on wou ...

Peroxisome proliferator-activated receptor gamma (PPAR gamma) is a nuclear receptor, which controls adipocyte differentiation. We targeted with homologous recombination the PPAR gamma 2-specific exon B, resulting in a white adipose tissue knockdown of PPAR ...
We have engineered synthetic poly(ethylene glycol) (PEG)-based hydrogels as cell-ingrowth matrices for in situ bone regeneration. These networks contain a combination of pendant oligopeptide ligands for cell adhesion (RGDSP) and substrates for matrix metal ...
Synthetic hydrogels have been molecularly engineered to mimic the invasive characteristics of native provisional extracellular matrixes: a combination of integrin-binding sites and substrates for matrix metalloproteinases (MMP) was required to render the n ...
OBJECTIVE: The peroxisome proliferator-activated receptor-gamma (PPARgamma) plays a role in adipocyte differentiation and insulin sensitization. It has been shown that genetic variation in the PPARgamma gene alters body weight control, lipid and insulin ho ...
A model of tissue differentiation at the bone-implant interface is proposed. The basic hypothesis of the model is that the mechanical environment determines the tissue differentiation. The stimulus chosen is related to the bone-implant micromotions. Equati ...
CONTEXT: Leptin was initially proposed to be the antiobesity hormone. Now it is realised that leptin is more a signal molecule that communicates nutritional status to the brain, and that it is involved in bone formation by having an antiosteogenic action. ...
We have explored the effects of two members of the p160 coregulator family on energy homeostasis. TIF2-/- mice are protected against obesity and display enhanced adaptive thermogenesis, whereas SRC-1-/- mice are prone to obesity due to reduced energy expen ...
The present study investigates the respective roles of both the host immune response and the metabolic requirements in determining the long-term survival of erythropoietin-secreting myoblasts within encapsulating polymer membranes. Hollow-fiber capsules lo ...
beta-Catenin is an essential component of the canonical Wnt signaling system that controls decisive steps in development. We employed here two conditional beta-catenin mutant alleles to alter beta-catenin signaling in the central nervous system of mice: on ...
