Outline of Final Research Achievements |
Pulmonary surfactant proteins, SP-A and SP-D, suppress the growth and progression of lung cancer cells by attenuating the EGF signaling of EGFR phosphorylation and its downstream. SP-D interferes with the EGF binding to EGFR by binding to the high mannose type-sugar moieties of EGFR. SP-A binds to EGFR in a Ca2+-independent manner, indicating the different mechanism from that of SP-D. SP-A and its peptide (SAP01:Tyr161-Lys201) attenuate mast cell migration stimulated with hBD3 and weakened the accumulation of mast cells in the tracheas of asthma model rats. SP-A protein was modified by cigarette smoke extract (CSE) and acrolein containing in the cigarette smoke. The reduction of reactive thiol in the SP-A molecule and the addition of acrolein was observed. The modified SP-A exhibited the decreased ability to attenuate the E. coli growth.
