Figure 4: Cigarette smoke condensate could change p120 catenin distribution and block it binding to neprilysin. (a and b) BEAS-2B cell was treated with cigarette smoke condensate and stained for p120 catenin. Plot profile analysis for p120 catenin distribution was employed here. (c) Co-IP experiments showed binding of neprilysin and p120 catenin could be reversed by cigarette smoke condensate treatment. Data were represent here as mean ± standard error of mean (**P < 0.01)
