Abstract

GH, 0.8 +/- 0.7 microg/l; IGF-I, 203 +/- 67 microg/l. In the CONTROLS the level of expression of PPARgamma mRNA was 15230 +/- 891 transcripts. Patients with AcroUntr had 2750 +/- 688 transcripts of PPARgamma. (p < 0.0001) vs. CONTROLS); patients AcroSMSa had 4629 +/- 1286 transcripts of PPARgamma. (p = NS vs AcroUntr, p = 0.0002 vs. CONTROLS); patients with AcroRem had 8261 +/- 2481 transcripts of PPARgamma (p = 0.008 vs. AcroUntr, p = NS vs. AcroSMSa, p = 0.007 vs. CONTROLS). A significant inverse correlation was found between serum IGF-I concentrations and the level of expression of PPARgamma (r = 0.43, p = 0.03). In conclusion, patients with active Acro have a reduced expression of PPARgamma in the colonic mucosa, which appears be related to the increased serum IGF-I levels and might lead to an increased prevalence of colonic polyps.
