Figure 4 Regulating function of HOTAIR in gastrointestinal cancer. In nucleus, HOTAIR recruits PRC2 complex and represses pri-miR-34a transcription epigenetically. By inducing histone H3K27 methylation in WIF-1’s promoter region, HOTAIR decreases WIF-1 expression. In cytoplasm, HOTAIR serves as “sponges” for miR-331-3p and miR-152, leading to the increase of target genes HER2 and HLA-G. PRC2: Polycomb repressive complex2.
