Lung maturation before birth includes type II pneumocyte differentiation with progressive disappearance of glycogen content and onset of surfactant synthesis. We have shown previously that 1,25-(OH)2D3 increases surfactant synthesis and secretion by type II cells and decreases their glycogen content in fetal rat lung explants. Recently, the gene coding(More)
Iron overload occurs frequently in thalassemia as a consequence of regular blood transfusions, and iron has been found to accumulate in bone, but skeletal toxicity of iron is not clearly established. In this study, bone biopsies of thalassemic patients were investigated by light (n = 6) and electron microscopy (n = 8) in order to analyze iron distribution(More)
Malignant osteopetrosis is characterized by impaired osteoclast activity. Osteoclasts derive from hematopoietic stem cells. In osteopetrosis, marrow cavities fail to develop, resulting in extramedullary hematopoiesis and the presence of stem cells in the bloodstream. Resistance to 1,25-(OH)2D3 may be involved in the pathogenesis of the disease. Sensitivity(More)
Malignant infantile osteopetrosis is a severe congenital disease characterized by impaired osteoclast activity. Among the multiple factors that influence bone resorption, the c-src protooncogene product pp60c-src plays an essential role, since mice which lack pp60c-src develop osteopetrosis. To gain insight into the possible role of pp60c-csrc in the(More)
