Biochem/physiol Actions

Rostafuroxin is a derivative of digitoxigenin. It protects animal models against podocyte lesions and proteinuria by counteracting mutant β-adducin and ouabain-mediated effects.
Rostafuroxin is a digitoxygenin derivative that selectively antagonizes the effects of endogenous ouabain on the Na+,K+-ATPase, which maintains sodium and potassium ion gradients across plasma membranes. Rostafuroxin lowers blood pressure (BP) in animal models of hypertension.

Glomerulopathies are important causes of morbidity and mortality. Selective therapies that address the underlying mechanisms are still lacking. Recently, two mechanisms, mutant β-adducin and ouabain, have been found to be involved in glomerular podocytopathies and proteinuria through nephrin downregulation. The

Many enveloped viruses induce multinucleated cells (syncytia), reflective of membrane fusion events caused by the same machinery that underlies viral entry. These syncytia are thought to facilitate replication and evasion of the host immune response. Here, we report that co-culture
