In this study we evaluated the expression of PPARgamma in the biopsy samples of the polyps and outside polyps colonic mucosa from seven patients with active, untreated acromegaly, 11 with cured disease, and 15 controls.
In this study the expression and mutations of the PPARgamma gene in the colonic polyps and mucosa outside polyps were investigated in 10 acromegalic and 17 non-acromegalic patients.
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.
