Figure Lengend Snippet: SE-associated LINC01013 was transcriptionally activated by CEBPB in hPASMCs. A Prediction of candidate transcription factors and binding sites. (Transcription factor related databases: JASPAR: https://jaspar.elixir.no/ ; PROMO: https://alggen.lsi.upc.es/cgi-bin/promo_v3/promo/promoinit.cgi?dirDB=TF_8.3 ; GENECARD: https://www.genecards.org/ ; AnimalTFDB: http://bioinfo.life.hust.edu.cn/HumanTFDB/#!/ ; Super enhancer related database: LncSEA: https://bio.liclab.net/LncSEA/ ). B The schematic diagram illustrates the LINC01013 promoter, divided into segments P1-P4, and the binding sites of transcription factors. C Four constituents (E1-E4) of SE region of LINC01013 derived from the WashU Epigenome Browser databases ( http://epigenomegateway.wustl.edu/browser/ ). D , E hPASMCs were subjected to ChIP analysis using antibodies against H3K27ac, H3K4me1 and CEBPB. The association with the SE region (D, E1-E4) and promoter region (E, P1-P4) of LINC01013 was quantified by RT‒qPCR ( n = 3). F hPASMCs were treated with CEBPB siRNA and subjected to ChIP analysis using antibodies against H3K27ac. The association with the E2 of SE (left) and P1-P3 promoter regions (right) of LINC01013 was quantified by RT-qPCR ( n = 3). G Schematic diagram of transcribing LINC01013 in hPASMCs. All values are presented as the mean ± SEM. Statistical analysis was performed with one-way ANOVA or Student’s t-test. * p < 0.05, ** p < 0.01, *** p < 0.001. Nor, normoxia; Hyp, hypoxia; NC, negative control; IP, immunoprecipitation; IgG, Immunoglobulin G; TSS, transcription initiation site
