Q: Question: Does increased ratio of mRNA expression of the genes CYP17 and CYP11B1 indicate autonomous cortisol production in adrenocortical tumors?
Answer: The ratio between the expression of the genes CYP17 and CYP11B1 in tumors from patients with Cushing's syndrome is significantly higher than in the non-hyperfunctioning tumors. This indicates that 17alpha-hydroxylase is a major determinant of cortisol overproduction. The patients with subclinical Cushing's syndrome in this study are too few to draw any firm conclusions although the results suggest that subclinical Cushing's syndrome may be identified post-operatively with this method.

A:
yes
