Figure Lengend Snippet: Effects of integrin β1 overexpression on cellular and secreted mucin 5AC (MUC5AC) and mucin 5B (MUC5B) levels in NCI–H292 cells. A, NCI–H292 cells were transfected with integrin β1 (β1 cDNA) or control vectors (CNTL) and cultured on a 96-well plate. Integrin β1 and β-actin protein levels were detected in cells via immunoblotting with specific antibodies, and their levels were measured using ChemiDoc. B, MUC5AC levels in transfected cells were detected using the dot blot method and measured (cellular). C, MUC5AC levels were detected in the culture medium of transfected cells via the dot blot method and measured (secreted). Fold changes were based on control cells (mean ± standard deviation [SD], n = 5). D, MUC5B levels in the transfected cells were detected using the dot blot method and measured (cellular). E, MUC5B levels in the culture medium of the transfected cells were detected using the dot blot method and measured (secreted). Fold changes were based on control cells (mean ± SD, n = 5). Fold changes were normalized for cell numbers. Student's t-test was used to obtain p -values. Asterisks indicate statistical significance, * p < 0.05. Representative results for three independent experiments are presented.
