Neprilysin (CD10) is expressed in both normal and neoplastic liver tissue, where it exhibits a characteristic canalicular pattern (CD10can) similar to the one observed when antibodies cross-react with biliary glycoprotein I (p-CEA). The aim of this retrospective study was to investigate the use of CD10can in differentiating between hepatocellular carcinomas (HCCs; 63 specimens) and nonhepatocellular carcinomas (non-HCCs) metastatic to the liver (non-HCC; 25 specimens). Immunostaining was performed with antibodies directed against CD10, p-CEA, and alpha-fetoprotein (AFP). Albumin mRNA was detected by nonradioactive in situ hybridization (ISHalbumin). In the HCC group a canalicular staining pattern for CD10 was found in 43 (68.3%) specimens. AFP was found in 15 (23.8%) specimens, and a canalicular staining pattern for p-CEA was present in 60 (95.2%) specimens. ISHalbumin was performed in 35 HCC specimens and showed labeling of tumor cells in 30 (85.7%) specimens. In the non-HCC group, CD10can, and p-CEA, immunostaining for AFP and labeling for ISHalbumin were confined to non-neoplastic liver tissue. Sensitivity and specificity were, respectively, 68.3% and 100% for CD10can, 23.8% and 100% for AFP, 95.2% and 100% for canalicular p-CEA, and 86.4% and 100% for ISHalbumin. Our results demonstrate that canalicular staining for CD10 is a highly specific marker of hepatocytic differentiation. Although it does not differentiate between benign and malignant lesions, CD10can is clearly useful in differentiating between HCC and non-HCC.

Diabetic nephropathy is a serious complication of diabetes associated with a poor prognosis which deteriorates to end-stage renal disease. Increased urinary excretion of protein and albumin are early clinical markers for diabetic renal disease and increased risk of cardiovascular disease. Diabetes causes activation of the renal endothelin system inducing renal damage. We analyzed the effects of SLV306, an inhibitor of both neutral endopeptidase and endothelin-converting enzyme, on diabetes-induced alterations of kidney function and morphology in rats with streptozotocin-induced diabetes. The effects of SLV306 (30 mg/kg per day), captopril (10 mg/kg per day), and placebo on urinary protein and albumin excretion as well as on blood pressure were studied in diabetic rats in comparison to non-diabetic control rats. The rats were treated for 20 weeks. At the end of the study kidney morphology was also analyzed using computer-aided image analysis systems. Serum glucose and blood pressure were similar in all diabetic groups. No side-effects were observed with SLV306 and captopril treatment. Protein excretion was 17.3 +/- 3.0 mg/24 hours in untreated diabetic rats. Protein excretion decreased significantly in the SLV306 (4.8 +/- 0.9 mg/24 hours; P = 0.03 vs untreated diabetic rats) as well as in the captopril (5.1 +/- 1.0 mg/24 hours; P = 0.03 vs untreated diabetic rats) -treated diabetic rats. Albumin excretion was 0.51 +/- 0.12 mg/24 hours in the untreated diabetic group and decreased likewise in the SLV306-treated diabetic rats (0.09 +/- 0.03 mg/24 hours; P = 0.04 vs untreated diabetic rats). The captopril-treated diabetic rats showed a strong trend towards reduced albumin excretion (0.12 +/- 0.04 mg/24 hours; P = 0.06 vs untreated diabetic rats). Computer-aided image analysis revealed that renal interstitial matrix content was significantly decreased in diabetic rats treated with either the angiotensin-converting enzyme inhibitor or the neutral endopeptidase/endothelin-converting enzyme inhibitor as compared to untreated diabetic rats. It was found that SLV306 decreases renal matrix protein content as well as protein and albumin excretion in diabetic rats independent of blood pressure. These effects are comparable to those of angiotensinconverting enzyme inhibition.
