In Myxococcus xanthus, morphogenesis of multicellular fruiting bodies and sporulation are co-ordinated temporally and spatially. csgA mutants fail to synthesize the cell surface-associated C-signal and are unable to aggregate and sporulate. We report that csgA encodes two proteins, a 25 kDa species corresponding to full-length CsgA protein and a 17 kDa(More)
Non-small cell lung cancers (NSLC) are aggressive cancers that are insensitive to chemotherapies and accounts for nearly 33% of all cancer deaths in the United States. Two hallmarks of cancer that allow cells to invade and metastasize are sustained proliferation and enhanced motility. In this study we investigate the relationship between urokinase(More)
The sodium hydrogen exchanger isoform one (NHE1) plays a critical role coordinating asymmetric events at the leading edge of migrating cells and is regulated by a number of phosphorylation events influencing both the ion transport and cytoskeletal anchoring required for directed migration. Lysophosphatidic acid (LPA) activation of RhoA kinase (Rock) and the(More)
