Adipocyte conversion of cultured 3T3-L1 preadipocytes by bezafibrate.
Transient exposure of cultured 3T3-L1 preadipocytes to hypolipidemic fibrate drugs results in extensive adipocyte conversion. Adipocyte conversion in culture was characterized by an increase in neutral lipids content and in adipocyte marker enzymes like hormone-sensitive lipase and glycerol-3-phosphate dehydrogenase. Adipocyte conversion in culture was also accompanied by induction of cyanide-insensitive peroxisomal palmitoyl-CoA oxidation. The conversion pattern exerted by fibrate drugs in 3T3-L1 cells was similar to that reported previously for primary cultured epididymal preadipocytes (R. Brandes, R. Arad and J. Bar-Tana, Biochim. Biophys. Acta, 877, 314-321 (1986)), and seems to refute clonal selection in the conversion sequel initiated by fibrate drugs in primary cultured preadipocytes.
