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...
متن کاملPotent constrictor actions of endothelin-1, endothelin-2, and endothelin-3 in rat isolated portal vein.
In rings of rat portal vein, endothelin-1, endothelin-2, and endothelin-3 caused graded slow contractions and potentiated spontaneous contractions. The apparent EC50 values and maximal responses to 30 nM endothelin were 1.4 nM and 0.96 g for endothelin-1, 5.2 nM and 0.65 g for endothelin-2, and 1.7 nM and 0.62 g for endothelin-3 (n = 4-12). At concentrations producing half the contraction trigg...
متن کاملUpregulation 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...
متن کاملNeonatal endothelin-1 concentrations in term infants.
Endothelin-1 concentrations were studied in 30 term infants during the first week of life using a radioimmunoassay kit. A neonatal reference range was established (7.5-25.7 pmol/l). No significant relation with age, sex, gestation, or birth weight was found.
متن کاملGene expression of endothelin-1, endothelin-converting enzyme-1, and endothelin receptors in human epididymis.
We have previously reported the presence of endothelin-1 (ET-1) and its receptors in the human testis. In the present study we extended our investigations to human epididymis. The rationale of our study originated from the fact that sperm appear to be immotile during their transit through the epididymis. Hence, it is conceivable that specific factors, unknown to date, are present in this organ,...
