(C) Venn diagram illustrating the overlap of differentially expressed (FC>1.5, p<0.05) transcripts between any of the three comparisons: EV to SOX9-WT (upregulated: 145+308+21; downregulated 146+333+44), EV to SOX9-T236/T240A (upregulated: 294+308+95+21; downregulated 345+333+95+44), or SOX9-WT to SOX9- T236/T240A (upregulated: 112+95+21; downregulated 114+95+44). Each oval represents the number of transcripts either upregulated or downregulated in the respective comparison, where the direction of differential expression is indicated by the inequality sign in the label. Numbers in overlapping regions signify the number of transcripts commonly differentially expressed in all contributing comparisons.
