  1. Expression profiles are shown under the cluster number: full lines are hypoxic time points and dashed lines are normoxic time points. For example, expression of the genes in cluster 1, both hypoxic and normoxic, declined over the course of the experiment, but hypoxic expression declined at a faster rate (steeper slope).
