Our work directly analyzed 15 genes that were identified with transcriptional screening, 3 of which are directly related to stemness (NOTCH3, C-KIT and PAX8) and 5 of which were direct markers of CSCs (ALDH1, ABCG2, CXCR4, CD133 and NANOG) in ovarian tumor samples from platinum-resistant patients, corroborating this relationship. Here, NOTCH3 is linked to ovarian neoplasm.
