ABSTRACT
Insulin is the important regulator of adipose cell metabolism and activates the branched out network of the signaling pathways supervising glucose transport, glycogen synthesis, lipogenesis stimulation, lipolysis inhibition and adipokine secretion. The purpose of our work is the analysis of structure of regulatory contours providing the response of mammalian adipocytes to insulin. With use of computer technology GeneNet adipocyte regulatory-effector network has been reconstructed. The network generalizes experimental data concerning the main insulin-dependent signaling pathways and their targets in a context insulin-sensitive metabolic processes and transcription events. Analysis of the network revealed positive and negative regulatory contours including MAP kinase-, Cbl/TC10- and P13K-dependent signaling pathways. Regulatory contours functioning with participation of transcription factors SREBP-1c, PPARgamma/RXRalpha, C/EBPalpha, FOXO1 are defined also. The major effectors of regulatory contours are glucose carrier GLUT4, and kinase mTOR.
