ACAA2 and neoplasm: To confirm these findings in vivo, xenograft experiments were conducted with ACAA2‐WT MDA‐MB‐231 cells and ‐Mock vector‐transfected cells (Figure 5I), and the tumor volume and weight were monitored; both of these parameters were greater in the ACAA2‐WT group than in the ‐Mock group (Figure 5J).
