FSTL3 and ovarian cancer: To do so we compared FSTL3 transcript levels from an RNAseq dataset of the TCGA ovarian cancer UNC hub (n=308) annotated with the molecular subtypes as proliferative, immunoreactive, differentiated, and mesenchymal, and found that FSTL3 was significantly higher in the mesenchymal subtype compared to all others (Fig. 5F).
