Abstract

Adipose tissues play a crucial endocrine role in the control of whole body glucose homeostasis and insulin sensitivity. Considering the current substantial rise in obesity and obesity-related diseases, including diabetes, it is important to understand the molecular basis of adipocyte differentiation and its control. In this study, we have analyzed the protein expression inherent to adipogenic differentiation, by 2-DE, MALDI-TOF, and RT-PCR. This study focused on proteins that were differentially expressed by the differentiation of human mesenchymal stem cells (hMSCs) to adipocytes. We conducted 2-DE for each set of proteins in the cytosol of adipocytes that had differentiated from hMSC, in a pH range from 3-10. Thirty-two protein spots were shown to have different expression levels. Among these, eight up-regulated proteins were identified by MALDI-TOF/MS, as the following: syntaxin binding protein 3, OSBP-related protein 3, phosphodiesterase, glycophorin, immunoglobulin kappa chain variable region, peroxisome proliferative activated receptor gamma (PPAR-γ), bA528A10.3.1 (novel protein similar to KIAA01616, isoform 1), and T cell receptor V-β 4. Four proteins: syntaxin-3, OSBP-related protein 3, PPAR-γ and glycophorin were associated with adipogenesis.
