POU5F1 and cancer: For instance, linc-ROR affects the expression of the stemness factors Nanog, Oct4, and SOX2 and regulates the maintenance of human embryonic stem cells (hESCs) via sponging miR-145 [72]. Further, upregulation of linc-ROR in BC resulted in a higher stem cell phenotype and greater mammosphere development, indicating that the Linc-ROR-miR-145 pathway is critical in cancer stemness [117, 118].
