Abstract
The preadipocyte-adipocyte conversion process from two intraabdominal (parametrial and perirenal fat depots) is differently affected by ovarian status in the rat. We have tested the hypothesis that these sitespecific alterations of adipogenesis might be related to changes in the expression of the transcription factors c-myc and CCAAT/enhancer binding proteins (C/EBPα,-β, and-ζ) that regulate proliferation and differentiation. The increased proliferation rates observed in parametrial and perirenal preadipocytes after ovariectomy were not linked to variations in c-myc mRNA levels. Expression of the early marker of adipogenesis, lipoprotein lipase (LPL), remained insensitive to the ovarian status in early differentiated parametrial and perirenal preadipocytes. By contrast, LPL expression increased in early differentiated sc preadipocytes from ovariectomized rats, an, effect that was completely reversed by in vivo estradiol and progesterone treatment. Expression of C/EBPβ protein was unaffected by ovarian status whatever the anatomic origin of the preadipocytes. By contrast, the levels of p42 and p30 isoforms of C/EBPα were specifically decreased in parametrial preadipocytes, an alteration that was completely corrected by in vivo administration of estradiol and progesterone. C/EBPζ, a dominant inhibitor of C/EBPα and β, exhibited a strong site-specific expression since C/EBPζ content was fivefold higher in sc preadipocytes than in deep intraabdominal cells whatever the ovarian status. Furthermore, ovariectomy selectively decreased C/EBPζ levels in sc cells. In conclusion, our study suggests that some of the site-specific effects of ovariecaltered expressions of C/EBPα and ζ, both of which are important transcriptional regulators of fat cell differentiation and metabolism.
