In situ, this pathway facilitated the invasion-metastasis cascade of breast cancer by repressing the expression of hox transcription factor protein D10 (homeobox D10 or HOXD10), progesterone receptor 1 (PRG1), cell adhesion molecules protocadherins (PCDHs), and tumor angiogenesis-related molecular ephrin receptors [16]. Here, HOXD10 is linked to neoplasm.
