Validation of histological diagnostic methods for detecting endothelin B receptor expression

Validation of histological diagnostic methods for detecting endothelin B receptor expression.

Pancreatic ductal adenocarcinoma (PDAC) has an extremely poor prognosis. Recently, it was reported that the endothelin B receptor (ETBR) of tumor endothelial cells prevents antitumor immunity. However, the immuno-histochemistry (IHC) conditions required to detect ETBR expression remain unclear. The aim of the present study was to confirm the appropriate conditions for IHC for ETBR using ETBR cD...

Upregulation of Endothelin-1/Endothelin A Receptor Expression Correlates with Heparanase Expression in Ovarian Carcinoma

Background: Heparanase and endothelin-1/endothelin A receptor (ET-1/ETAR) expressions increase in cancer. This condition enhances tumor progression and correlates with poor survival. Limited data are documented regarding the role of heparanase and ET-1/ETAR in epithelial ovarian cancer (EOC). We sought to characterize the correlation between heparanase and ET-1/ETAR in EOC.Methods: Thirty patie...

Developmental changes in Endothelin-1 and Endothelin type A receptor expression in the lungs of chickens (Broiler versus layer)

Background: Broilers lung mechanisms that regulate endothelin (ET) in the lung are complex and poorly understood. Objectives: Methods: In this experiment lung ET-1 mRNA levels and lung mRNA expression for the ET(A) receptors were determined in lung tissue weekly (term = 42 days, intervals = 7 days). Serum endothelin concentration was also measured at these ages. Results: The study showed that e...
