Studies on a cellular breast-cancer model showed that inhibition of the cAMP-specific PDE (phosphodiesterase) activity of h-Prune lowered the incidence of metastasis formation, suggesting that inhibition of h-Prune could be a therapeutic approach towards metastatic tumours."

"H-Prune shows no sequence similarity with known mammalian PDEs, but instead appears to belong to the DHH (Asp-His-His) superfamily of phosphoesterases. In order to investigate the...
