Figure 9 Survival-associated SFs and splicing correlation network in HCC patients. (A) Splicing correlation network. AS events with PSI values negatively/positively associated with survival are shown in red/green dots, respectively. SFs related to survival are presented as purple dots. Green/red lines represent negative/positive between SFs expression and PSI values of AS, respectively. (B) High expression (red line) of splicing factor SRSF2 is strongly related to poor disease-free survival (left panel) and poor overall survival (right panel). (C) Dot plot of correlation between expression of SRSF2 and AP PSI values of CAPRIN1 (left panel), and the correlation between ES PSI values of SULT1A2 and expression of SRSF2 (right panel).
