OVOL2 and breast neoplasm: Substantial evidence demonstrates the significance of fatty acid oxidation in breast tumor progression.[31, 32, 33] Compared to glucose, fatty acid could generate more energy and antioxidants through fatty acid oxidation.[5, 34, 35, 36] Here, by RNA‐Seq analysis, we discovered that OVOL2 negatively regulated fatty acid degradation in TNBC cells.
