Fig. 4. a. Overview of the identified differentially expressed
SD rat plasma proteins. b. Pie chart showing the most
significant molecular and cellular processes across hypoxic groups using
normalized protein fold change values. c. Hierarchical
clustergram of identified plasma 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 (orange: up-regulation; blue:
down-regulation; white: neutral; grey: no directionality).
