ARHGAP18 and obesity disorder: MiR-200 family’s components target other genes that antagonize malignant processes, among them Rho GTPase-activating protein 18 (ARHGAP18), an important regulator of cell shape, spreading, migration, and angiogenesis [143] and the leptin receptor (OBR), which promotes the formation of cancer stem-like cells (CSCs) and up-regulates the obesity-associated adipokine itself associated to BC [144].
