Time-response curves for cAMP induction and concentration-response curves for aromatase induction by vinclozolin, atrazine, and IBMX were similar, suggesting that the mechanism of aromatase induction by these pesticides is mediated through inhibition of phosphodiesterase activity.

Leydig cells from treated rats were characterised by significant decline in mRNA transcripts of several genes responsible for steroidogenesis: luteinizing hormone receptor (LHR), scavenger receptor-B1, steroidogenic acute regulatory protein, translocator protein, steroidogenic factor-1, phosphodiesterase 4B, 3beta-hydroxysteroid dehydrogenase (HSD), CYP17A1, and 17betaHSD.

Therefore, ATR and its degradation products were studied to determine their ability to inhibit phosphodiesterase (PDE), the enzyme responsible for hydrolyzing the second messenger cAMP to 5'-AMP.

Environ Health Perspect. 2007 May;115(5):720-7. Epub 2007 Feb 5.

The mechanism involves the inhibition of phosphodiesterase and subsequent elevation of cAMP.
