highly significantP < 2.6∗10 -15
Remarkably, functional analysis of HIF1A targets in the category of biological process showed highly significant enrichment of the GO terms response to unfolded protein ( P < 2.6∗10 -15 ), regulation of cellular response to stress ( P < 2.1∗10 -13 ), and protein folding ( P < 3.0∗10 -13 ) ( Figure 3 B , Supplementary Table 6 ).
