Patients with TSC often develop renal cysts and those with inherited co-deletions of the autosomal dominant polycystic kidney disease (ADPKD) 1 gene (PKD1) develop severe, early onset, polycystic kidneys.
Here, we report a sustained activation of the transcription factor signal transducer and activator of transcription 3 (STAT3) in ischemic injured and uninjured Pkd1 knockout polycystic kidneys and in human ADPKD kidneys.
