(A) RNA-seq flowchart and DEG classification. RNA-seq data were from MDA-MB-231 with or without BRD4 isoform-specific knockdown.
(B) Top canonical pathways identified for BRD4-S/L DEGs highlighting S-unique-upregulated matrisome network (red) and L-preferred-downregulated core ECM (blue).
(C) Heatmap of top DEGs from MDA-MB-231 RNA-seq divided into up and downregulated (Dn) groups, each in triplicate. Scale bar is based on the Z score of CPM (counts per million).
(D) List of BRD4-S-upregulated matrisome genes with significantly higher expression in IDC vs. normal breast samples (P values from Oncomine METABRIC 2136 BCa dataset).
(E) Unique gene families identified in BRD4-S-upregulated RNA-seq from MDA-MB-231.
(F) Kaplan-Meier plot showing higher expression of a 17-matrisome-gene signature identified in S-Up predicts unfavorable DMFS in basal subtype patients. The 17 DEGs analyzed are indicated.
