APOA1 and glioblastoma: To further evaluate the antitumor efficacy of ApoA1 in vivo, we established two APOA1-expressing GBM cell lines (GL261APOA1 and G422APOA1) and observed prolonged survival only in immunocompetent mice bearing orthotopic APOA1-expressing GBMs, but not in immunodeficient mice (Fig. 3e).
