ABSTRACT<br />

Glucocorticoids (GC) play an important role in <strong>de</strong>termining the distribution of<br />

adipose tissue and metabolism. Individuals with Cushing's syndrome (CS) show a<br />

pattern of central obesity, related to excessive levels of plasma glucocorticoids<br />

exogenous or endogenous origin which is reversible after treatment or withdrawal<br />

of corticosteroids. The mechanisms involved in the distribution of adipose<br />

tissue mediated by glucocorticoids are not fully un<strong>de</strong>rstood. The objective of<br />

this study was to quantify and evaluate the effects of chronic exposure to<br />

hypercortisolism in the gene expression of components of the kallikrein-kinin<br />

fat <strong>de</strong>posits in patients with Cushing's Syndrome. Samples of visceral (VAT)<br />

and subcutaneous adipose tissue (SAT) were obtained during elective abdominal<br />

surgery for female patients with Cushing's Syndrome (n = 9), in which the body<br />

mass in<strong>de</strong>x (BMI), waist circumference (WC) and salivary cortisol (CTS) were<br />

previously <strong>de</strong>termined. The mRNA expression of tissue kallikrein and<br />

the kinin B1 and B2 receptors were quantified by real-time PCR. The mRNA<br />

expression of kinin B2 receptor in SAT and VAT of Cushing's patients was similar<br />

in both compartments (p> 0.05). The expression of kinin B1 receptor was<br />

reduced in SAT when compared to VAT of patients with Cushing (p
