Figure Lengend Snippet: CITED2 is the target gene of SEs. (A, B) The hockey map lists target genes that are regulated by enhancers under normoxia and hypoxia. The entire curve consists of many points, each of which represents a gene. The right side of the image represents genes regulated by SEs. (C) The images represent the level of H3K27ac modification upstream of the CITED2 promoter under normoxia and hypoxia. (D) The three gene fragments and promoter fragments were loaded into plasmids for dual luciferase experiments. In the experimental group with three gene segments, the luciferase activity was higher, and the fluorescence intensity was stronger. (E) The ChIP‐PCR experiment was carried out according to the primers of the promoter constructed by the CITED2 gene and these three gene sequences. The results showed that the region upstream of the CITED2 gene promoter, including the promoter, had significant H3K27ac modification. The fifth primer represented the desert region of the gene. (F) RT‐qPCR results of CITED2 mRNA level after treatment of JQ‐1 and i‐BET. Nor: normal, Hyp: hypoxia, SE: super‐enhancer. (Bar = mean ± S.E.M, * p < 0.05; ** p < 0.01; *** p < 0.001; **** p < 0.0001).
