Physical And Functional Coupling Of Cftr And Pde3a, Himabindu Penmatsa
Theses and Dissertations (ETD)
Formation of multiple-protein macromolecular complexes at specialized subcellular microdomains increases the specificity and efficiency of signaling in cells. In this study, we demonstrated that phosphodiesterase type 3A (PDE3A) is physically and functionally coupled to cystic fibrosis transmembrane conductance regulator (CFTR). PDE3A inhibition increases cyclic adenosine 3′, 5′-monophosphate (cAMP) levels in a compartmentalized manner at the plasma membrane, which potentiates CFTR channel function and further clusters PDE3A and CFTR into microdomains. Actin skeleton disruption reduces PDE3A-CFTR interaction; segregates PDE3A from its interacting partners thus compromise the integrity of the macromolecular complex. Consequently, PDE3A inhibition no longer activates CFTR channel function in …

The endothelium repairs itself through two methods. One is by the activity of circulating endothelial progenitor cells (EPCs). EPCs are immature endothelial cells that circulate the bloodstream that are capable of proliferation and differentiation into mature endothelium. It is thought that EPCs contribute to the repair and replacement of damaged endothelial cells in the process of reendothelialization. Physical inactivity and bed rest are known to be deleterious to the endothelium. It is possible that this inactivity is also deleterious to the number of viable EPCs, which would reduce the ability of the endothelium to repair itself. We used hind limb …

Primary cilia, thin hair-like structures protruding from the apical surface of most mammalian cells, have gained the attention of many researchers over the past decade. Primary cilia are microtubule-filled sensory organelles that are enclosed within the ciliary membrane. They originate at the cell surface from the mother centriole that becomes the mature basal body. In this review, we will discuss recent literatures on the roles of cilia as sophisticated sensory organelles. With particular emphasis on vascular endothelia and renal epithelia, the mechanosensory role of cilia in sensing fluid shear stress will be discussed. Also highlighted is the ciliary involvement in …
