Ischemia-reperfusion injury is the major cause of delayed graft function in transplanted kidneys, an early event significantly affecting long-term graft function and survival. Several studies in rodents suggest that the alternative pathway of the complement system plays a pivotal role in renal ischemia-reperfusion injury. However, limited information is(More)
PURPOSE SPON2 belongs to the F-spondin family of secreted extracellular matrix proteins. It is deregulated in some tumors, including prostate cancer. In this prospective study we assessed the role of serum SPON2 as a biomarker for prostate cancer diagnosis as well as any association between SPON2 levels and clinicopathological features. We also compared the(More)
Testicular granulosa cell tumor of the adult type is a very rare tumor, and, to date and our knowledge, only 23 cases of this rare testicular tumor have been reported in the literature, 5 of which developed metastases. We report a case of granulosa cell tumor of adult type in a 45-year-old man with a 15-year history of a painless increasing right testicular(More)
PURPOSE In clear cell renal cell carcinoma tissue samples we identified and characterized a population of renal cell carcinoma derived CD133+/CD24+ cancer cells. We studied differences between these cells and their nonneoplastic counterpart, tubular adult renal progenitor cells. MATERIALS AND METHODS CD133+/CD24+ renal cell carcinoma derived cells were(More)
The placement of a double J stent to protect a uretero-vesical anastomosis in a kidney transplant is a widespread procedure performed to reduce the incidence of fistula and stenosis at the anastomosis. However, the presence of a double J stent may cause vesicoureteral reflux (VUR), predisposing one to urinary tract infections (UTIs), which may be a(More)
Alterations of integrin expression levels in cancer cells correlate with changes in invasiveness, tumor progression, and metastatic potential. The beta1C integrin, an alternatively spliced form of the human beta1 integrin, has been shown to inhibit prostate cell proliferation. Furthermore, beta1C protein levels were found to be abundant in normal prostate(More)
Malignancies are one of the main causes of mortality in diabetic patients; however, to date, very limited data have been reported on the specific influence of type 2 diabetes mellitus (T2DM) on the survival of patients with renal cell carcinoma (RCC). In the present long-term retrospective study, we investigated whether T2DM may influence the overall(More)
In this paper we studied the in vivo neoadjuvant Androgen Deprivation Therapy (ADT) effect on the expression of TGF-β1 and its receptor Tβ-RII. Mechanisms of androgen dependence are critical to understanding prostate cancer progression to androgen independence associated with disease mortality, and TGF-β is thought to support prostatic apoptosis as its(More)
Congenital 21-alpha hydroxylase deficiency is a syndrome characterized by a cortisol synthesis deficiency and, rarely, by testicular masses. We present a case of bilateral nodular hyperplasia of the testis without adrenal hyperplasia in a patient affected by 21-alpha hydroxylase deficiency. This mass mimicked a testicular tumor and made differential(More)
