Histologically, we never observed sarcomas or lymphomas arising in electroporated animals and, accordingly, all tumors analyzed expressed molecular hallmarks of human HGSOC, including Cytokeratin-7 (CK7), Wilms Tumor 1 (WT1), Cancer Antigen 125 (CA-125), Paired box 8 (Pax-8), and high Ki67 (Fig. 1F and SI Appendix, Fig. S1A). This evidence concerns the gene PAX8 and sarcoma.
