ASPH Is a Metastatic Factor and Therapeutic Target in Chondrosarcoma.

ABSTRACT: Background: Chondrosarcoma (CS) is a highly aggressive primary malignant bone tumor for which there are no effective systemic treatments. We assessed aspartate β-hydroxylase (ASPH) as a potential treatment target. ASPH is a transforming cell surface receptor, but its role in chondrosarcoma has not been evaluated. Our goals were to analyze the expression of ASPH in conventional chondrosarcoma, evaluate its utility as a biomarker, and determine if ASPH inhibition diminishes tumor progression in a preclinical model. Methods: An annotated tissue microarray was constructed with conventional chondrosarcoma tissues. ASPH expression was quantified with immunohistochemistry. A small molecule inhibitor (SMI) designed to inhibit ASPH activity was evaluated in two CS cell lines with inta
