Ugrinova, I. et al. Inactivation of nucleolin leads to nucleolar disruption, cell cycle arrest and defects in centrosome duplication.
After mechanical disruption, cell debris was pelleted by centrifugation (3000 rpm, 20 min, 4 °C) and the membranes were isolated from the supernatant by ultra-centrifugation (205,000 × g, 3 h, 4 °C).
After cell disruption, cell debris was removed by centrifugation (21,000 × g for 20 min).
Furthermore, the effects of magnetic labeling on the biological properties of A549 lung cancer cells, including cell viability, proliferation capacity, cytoskeletal disruption, cell cycle, and apoptosis, were investigated separately.
Injury of myofibers leads to rapid necrosis associated with sarcomere disruption, cell permeabilization, and proteolysis, which induces an acute inflammatory response characterized by the invasion of inflammatory cells (Brunelli and Rovere-Querini, 2008).
Apoptosis, or programmed cell death, is a highly regulated, morphologically and biochemically distinct physiological cell death event which is accompanied by cytoskeletal disruption, cell shrinkage, membrane blebbing, chromatin condensation, and internucleosomal DNA fragmentation [20].
It is thus likely that A101-mediated inhibition or disruption cell-surface and cell-cell interactions induced the antibiofilm effects.
A mutation in sec13, which is primarily involved in protein trafficking from ER to Golgi, causes similar ER disruption, cell-cycle arrest, and cell death phenotypes in zebrafish (Niu et al., 2012), thus substantiating the hypothesis that a secretory defect might be linked to the persistent ER stress pathology.
For disruption, cells were thawed, supplemented with 1 mM phenylmethanesulfonyl fluoride (PMSF), and sonicated well until the solution cleared completely.
For disruption, cells were initially shock-frozen in liquid nitrogen and then defrosted in a thermomixer (Eppendorf, Hamburg, Germany) at 1400 rpm at 30°C for 10 minutes.
Rack1 also blocks HGF-induced endocytosis of E-cadherin, disruption of cell-cell contacts and cell scatter.
