Figure Lengend Snippet: A. Schematic representation of the experimental design depicting the treatment of HepG2 cells with 10 μM BRM014 for 1, 6, and 24 h, as well as 6 h and 24 h recovery after 24 h BRM014 treatment. B. Average profiles of DNA conversion rate around OCR with or without SWI/SNF binding sites defined by ChIP-seq, illustrating changes in chromatin accessibility following different durations of BRM014 treatment and recovery (Control 0 h-32%, 1 h-31%, 6 h-32%, 24 h-29%, R6 h-33%, R24 h-33%). C. Heatmap showing TFOS change ratio in SWI/SNF+ regions across different BRM014 treatment conditions for 134 filtered TFs in HepG2 cells. The TFs are clustered into four groups based on change ratio of TFOS across treatments. Grids color represents the dynamic change ratio compared with controls D. Butterfly graph shows flanking chromatin accessibility change ratio (left) and TFOS change ratio (right) of representative TFs in different clusters, which represent changes in flanking accessibility and TF occupancy. E. Average profiles and heatmap of overall DNA conversion rate around HNF1A binding sites in SWI/SNF+ regions (left), illustrating changes in chromatin accessibility, nucleosome position and TF occupancy after BRM014 treatment and recovery. Plot graphs of flanking chromatin accessibility, TFOS and their change ratio are shown (Right). Flanking chromatin accessibility around the TF binding motifs are calculated as the average DNA conversion rate in the 50 bp flanking regions on both sides of the motif as flanking chromatin accessibility F-H. Average profiles of DNA conversion rate around TF binding sites of HNF4A and FOSL1 (F), FOXA1 and CEBPB (G), CTCF and YY1 (H) under control, 1 h, 6 h, and 24 h BRM014 treatments, as well as 6 h and 24 h recovery after 24 h BRM014 treatment. The profiles show changes in chromatin accessibility and TF footprints across different treatment conditions. See also Figures S8, Table S4
