Fig. 5From: Chemo-preventive effects and antitumorigenic mechanisms of beer and nonalcoholic beer toward 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) - induced lung tumorigenesis in A/J miceEffects of beer (a), NAB(A) (b), NAB(B) (c), GB (d) and PU (e) on A549 cell viability. The experiment was repeated thrice and standard deviation (SD) is indicated with the bar (n = 5). *Significantly different from each negative control (beer, NAB(A), NAB(B), GB or PU = 0) at P < 0.05.
