Effects of stress and the LPA1 receptor deficiency on hippocampal LPA concentrations. Stress exerted the greatest effects on (A) the hippocampal concentrations of total LPA and (B) LPA species in WT mice than in maLPA1-null mice. (C) Regarding the percentage of relative abundance, the effects of stress were only observed on LPA 18:1 and LPA 18:2. (D) Graphic representation of the percentage of relative abundance. ∗∗∗p ≤ 0.0005 compared with the control; ###p ≤ 0.0005 compared with the EPM; $p ≤ 0.05 and $$$p ≤ 0.0001 compared with maLPA1-null mice. p ≤ 0.05 compared with control groups. LPA 16:0; 18:0; 18:1, and 20:4 species [palmitic acid (16:0) and stearic acid (18:0)] [oleic (18:1), linoleic (18:2), and arachidonic acids (20:4)].
