  • Title: [Gene expression regulation of adipocyte differentiation: cell cycle and hormones].
    Author: Grimaldi P.
    Journal: Reprod Nutr Dev; 1990; 30(3):281-95. PubMed ID: 2204347.
    Abstract:
    The adipose conversion of cultured preadipose cells involves the activation of numerous genes and is controlled by various adipogenic and mitogenic factors. The differentiation program can be divided into early and late events. Early events are triggered by growth arrest at the G1/S boundary and characterized by the activation of a set of genes (pOb24, lipoprotein lipase, etc.). The expression of the terminal differentiation-related genes takes place after a limited growth resumption of early markers containing cells and requires the presence of permissive hormones (growth hormone and triiodothyronine). Insulin acts solely as a modulator in the expression of the terminal differentiation-related genes. In vivo studies suggest that the acquisition of new adipocytes might result from terminal differentiation of dormant, already committed (pOb24 positive) cells when exposed to appropriate mitogenic or adipogenic stimuli.
