Out of 61 cancer-associated FT sEV proteins, we identified several proteins that have a reported role in ovarian cancer or cancer in general, including fibronectin, S100 protein families (S100A7, S100A8, S100A9), integrin (ITGB1), heat shock proteins (HSP90), and versican core protein (VCAN), among others. This evidence concerns the gene FN1 and ovarian cancer.
