Apolipoprotein A1-Manipulated Cholesterol Efflux Subverts the Phagocytic Fragility of TAMs and Improves Oncolytic Viro-Immunotherapy in Glioblastoma [TAMs RNA-seq]
We found that TAMs in the glioblatoma (GBM) tumor microenvironment are enriched for cholesterol and highly express ABCA1/G1. To investigate the biological effects of enhancing cholesterol efflux of TAMs in GBM, we constructed APOA1-overexpressing GL261 cell line. We harvested tumor tissue and sorted these TAMs by anti-mouse F4/80 magnetic beads 17 days after intracranial transplantation of GL261-APOA1 cell line and control cells in immunocompetent C57 mice. Samples were subjected to transcriptome sequencing. Overall design: Comparative gene expression profiling analysis of RNA-seq data for TAMs sorted from GL261-APOA1 (n=4) or GL261-Puro (n=4) tumors
