Endothelin-1 and osteoblastic metastasis.
W hen cancer metastasizes to distant sites, it essentially forms an army of occupation. Just as the presence of an army of occupation alters the behavior of the preexisting resident population, the resident host cells react in a variety of ways to the presence of the metastatic cancer cells. In the majority of cases, they increase their resorptive or destructive capacity, and the result is an o...
متن کاملA causal role for endothelin-1 in the pathogenesis of osteoblastic bone metastases.
Osteoblastic bone metastases are common in prostate and breast cancer patients, but mechanisms by which tumor cells stimulate new bone formation are unclear. We identified three breast cancer cell lines that cause osteoblastic metastases in a mouse model and secrete endothelin-1. Tumor-produced endothelin-1 stimulates new bone formation in vitro and osteoblastic metastases in vivo via the endot...
متن کاملDevelopmental 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 کاملParaneoplastic hypocalcemia in a patient whit gastric cancer accompanied by osteoblastic metastasis
Paraneoplastic syndromes are generally defined as clinical disorder associated with malignant diseases, and hypocalcemia as paraneoplastic manifestation associated with cancer is a rare condition. In patient with bone metastatic cancer, osteolytic lesions are more common than osteoblastic ones which give rise to hypercalcemia and hypocalcemia is a rare condition in this group of patients. We de...
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...
