Description:
Obstruction of airways by viscous sputum causes lung damage in patients with cystic fibrosis (CF). Sputum samples from CF patients were shown to contain filamentous actin. Human plasma gelsolin, a protein that severs actin filaments, rapidly decreased the viscosity of CF sputum samples in vitro. Gc globulin and deoxyribonuclease I, proteins that sequester monomeric actin but do not sever actin filaments, were less efficient than gelsolin in diminishing sputum viscosity. These results suggest that gelsolin may have therapeutic potential as a mucolytic agent in CF patients.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vasconcellos, C A -- Allen, P G -- Wohl, M E -- Drazen, J M -- Janmey, P A -- Stossel, T P -- AR38910/AR/NIAMS NIH HHS/ -- HL19170/HL/NHLBI NIH HHS/ -- HL19429/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Feb 18;263(5149):969-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Brigham and Women's Hospital, Department of Medicine, Harvard Medical School, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8310295" target="_blank"〉PubMed〈/a〉
