ACAA2 and neoplasm: Moreover, further assessment of FFA levels revealed that mouse tumor tissues and MDA‐MB‐231 cells from the LDHC4‐OE and ACAA2‐WT groups presented higher FFA levels than those from the corresponding ‐Mock groups (Figure 6E), correspondingly, TNBC tissues with LDHC4 expression exhibited significantly higher FFA levels compared to matched adjacent nontumor tissues (Figure 6E), but LDHC4 and ACAA2 knockdown (with Si‐LDHC4 and Si‐ACAA2, respectively) in MDA‐MB‐468 cells had the opposite effects (Figure 6F).
