Polycystic kidney diseases are characterized by numerous bilateral renal cysts that continuously enlarge and, through compression of intact nephrons, lead to a decline in kidney function over time. We previously showed that cyst enlargement is accompanied by regional hypoxia, which results in the stabilization of hypoxia-inducible transcription factor-1α (HIF-1α) in ...

OBJECTIVE: Testicular tumours are rare in paediatric patients, accounting for only 1% of tumours in boys. Leydig cell tumours are the most common gonadal stromal tumours. Since these tumours are functionally active, secreting testosterone, they characteristicallyproduce isosexual pseudoprecocious puberty (IPP), the customary therapeutic choicebeing radical orchiectomy. Nowadays, considering that Leydig ...
