    ..These results suggest that UNC-78 closely collaborates with UNC-60B to regulate actin dynamics in muscle cells. ..

    ..Similar Unc-78 phenotypes are observed in both embryonic and adult muscles. Thus, AIP1 is an important regulator of actin filament organization and localization of ADF/cofilin during development of myofibrils. ..

    ..These data support a model in which this conserved surface of AIP1 plays a direct role in enhancing fragmentation/depolymerization of ADF/cofilin-bound actin filaments but not in barbed end capping. ..

    ..Thus, we propose a model in which tropomodulin and enhancers of actin dynamics synergistically regulate elongation and shortening of actin filaments at the pointed end. ..

    ..We conclude that an increase, not a decrease in fuel consumption, via an accelerated oxidation of fuels in the TCA cycle is involved in life span regulation; this mechanism may be conserved across phylogeny. ..

    ..Taken together, the study provides functional evidence for a crucial role of vitellogenins and the steroid-signaling pathway in determination of resistance against bacteria. ..
