As expected, the expression of the adipocytic genes aP2/fatty acid binding protein (FABP4), adiponectin and adipokine (AdipoQ), transcription factor PPARγ, and leptin in myelolipoma tissue revealed the presence of mature lipoid tissue in the myelolipoma compared to both CAH and control adrenal tissues. This evidence concerns the gene LEP and adrenal gland myelolipoma.
