(A) Scatter plot depicting the relationship between transcriptional changes measured as log2 FC between EV to SOX9-WT (x-axis) and EV to SOX9-T236/T240A (y-axis). Each dot represents one transcript, with colored dots indicating transcripts upregulated (log2 FC>0.585; p<0.05; red dots) or downregulated (log2 FC<-0.585; p<0.05; blue dots) in both comparisons. The transcript corresponding to the SOX9 gene is highlighted as a red filled dot. Indicated r-value indicates Spearman's rank correlation coefficient between the two FC profiles.
