Combination of a Histone Deacetylase 6 Inhibitor and a Somatostatin Receptor Agonist Synergistically Reduces Hepatorenal Cystogenesis in an Animal Model of Polycystic Liver Disease.
Tolvaptan therapy significantly improved cyst burden and slowed disease progression among patients with early-stage ADPKD in a large-scale trial, while somatostatin therapies may also be useful in halting disease progression and managing comorbid polycystic liver disease.
TGR5 contributes to hepatic cystogenesis by increasing cAMP and enhancing cholangiocyte proliferation; our data suggest that a TGR5 antagonist alone or concurrently with somatostatin receptor agonists represents a potential therapeutic approach in polycystic liver disease.(Hepatology 2017;66:1197-1218).
