ANTXR1 and neuroendocrine carcinoma: Although this association was identified in SCLC, it is likely, given TEM8/ANTXR1 is the receptor for SVV-001, that SVV-001 permissive subtypes of other neuroendocrine cancers share similar features to SCLC-N, including elevated TEM8/ANTXR1 and low expression of IFN genes.
