From: Gene-metabolite profile integration to understand the cause of spaceflight induced immunodeficiency

Spaceflight-induced stress in conjunction with LPS insult perturbs energy metabolism. The significantly altered genes and metabolites are integrated to construct this network. The shaded ovals are the metabolites and the edges represent their relationships. The arrowheads under each molecule represent their expressions attributed to microgravity (µG) in comparison to terrestrial condition (1 G) (left), and the 4 h LPS assaults in µG in comparison to 1 G (right). ▲ Represents up, ▼ represents down and ▬ represents no change
