Importantly, DEspR inhibition at the protein level via an anti-ratDEspR-specific polyclonal antibody decreased tumor growth, tumor vascularization, and nuclear malignancy-grade in irradiation-induced rat mammary tumors [22], thereby clarifying DEspR-specific pro-tumorigenic roles in contrast to the tumor suppressor roles of Fbxw7. Here, FBXW7-AS1 is linked to breast cancer.
