Fig. 4.
Changes in the levels of polyunsaturated fatty acids (PUFA) and oncometabolite 2-hydroxyglutarate (2-HG). a Methyl donor depletion causes a reduction in the levels of arachidonic acid (− 2.30, p < 0.04), a potential tumor-promoting metabolite. b Eicosapentaenoate (EPA) level was increased (1.33-fold) in MDD group and (2.0-fold, p < 0.013) in MDDR group indicating that the increased EPA level was sustained for at least seven weeks beyond dietary methyl donor repletion. c 2-hydroxyglutarate (2-HG), an oncometabolite was significantly reduced after methyl donor restriction (− 1.4-fold, p < 0.002. All groups marked with “a” have a statistically significant difference compared to groups marked with “b”
