Abstract (original English)
To examine whether GTP-binding protein(s) is (are) involved in adipocyte differentiation, the effect of pertussis toxin (PT) was studied in rat adipocyte precursor cell culture. PT potentiated adipose conversion induced by dexamethasone, insulin, and 1-methyl-3-isobutylxanthine in a dose- and time-dependent fashion. Attenuation of an inhibitory control of adenylate cyclase was not the mechanism of action of PT. The dose-dependent inhibition of PT-catalyzed ADP-ribosylation of the Mr 40,000 protein of the cell membrane by preincubation of the toxin was inversely related to the potentiating effect on differentiation. PT-sensitive G protein(s) may be involved in adipocyte differentiation in a negative fashion.
What this study does not prove
