http://purl.uniprot.org/citations/16807302http://www.w3.org/2000/01/rdf-schema#comment"Maintenance of bone structural integrity depends in part on the rate of apoptosis of bone-forming osteoblasts. Because substrate adhesion is an important regulator of apoptosis, we have investigated the role of focal adhesions in regulating bone cell apoptosis. To test this, we expressed a truncated form of alpha-actinin (ROD-GFP) that competitively displaces endogenous alpha-actinin from focal adhesions, thus disrupting focal adhesions. Immunofluorescence and morphometric analysis of vinculin and tyrosine phosphorylation revealed that ROD-GFP expression dramatically disrupted focal adhesion organization and reduced tyrosine phosphorylation at focal adhesions. In addition, Bcl-2 protein levels were reduced in ROD-GFP-expressing cells, but caspase 3 cleavage, poly(ADP-ribose) polymerase cleavage, histone H2A.X phosphorylation, and cytotoxicity were not increased due to ROD-GFP expression alone. Increases in both ERK and Akt phosphorylation were also observed in ROD-GFP-expressing cells, although inhibition of either ERK or Akt individually or together failed to induce apoptosis. However, we did find that ROD-GFP expression sensitized, whereas alpha-actinin-GFP expression protected, cells from TNF-alpha-induced apoptosis. Further investigation revealed that activation of TNF-alpha-induced survival signals, specifically Akt phosphorylation and NF-kappaB activation, was inhibited in ROD-GFP-expressing cells. The reduced expression of antiapoptotic Bcl-2 and inhibited survival signaling rendered ROD-GFP-expressing cells more susceptible to TNF-alpha-induced apoptosis. Thus we conclude that alpha-actinin plays a role in regulating cell survival through stabilization of focal adhesions and regulation of TNF-alpha-induced survival signaling."xsd:string
