Fig. 2. a. Overview of the identified differentially expressed
lung proteins. b. Pie chart showing the most significant
molecular and cellular processes across each hypoxic group using
normalized protein fold change values. c . Hierarchical
clustergram of identified lung proteins using normalized fold change
values. Green is down-regulated and red is up-regulated d . IPA
based analysis of the most significant pathways as well their overall
directionality based on z-scores (blue: down-regulation; white: neutral;
grey: no directionality).
