Phospholipid abundance and composition are altered in cortex after loss of Etnppl.A, volcano plot representing PC and PE species fold changes comparing EtnpplKO with WT using 18-h fasted cortex from 9-week-old mice. n = 5. B, volcano plot representing phospholipid species fold changes comparing Etnppl KO with WT using 18-h fasted liver from 9-week-old mice. C, total relative phospholipid abundance in the cortex from 18-h fasted, 9-week-old EtnpplKO and WT mice. n = 5. D, total relative phospholipid abundance in the cortex from 18-h fasted liver from 9-week-old Etnppl KO and WT mice. n = 5. E, relative total AA abundance in PC species in the cortex from 18-h fasted, 9-week-old Etnppl KO and WT mice. n = 5. F, relative total AA abundance in PE species in the cortex from 18-h fasted, 9-week-old EtnpplKO and WT mice. n = 5. G, relative total DHA abundance in PC species in the cortex from 18-h fasted, 9-week-old EtnpplKO and WT mice. n = 5. H, relative total DHA abundance in PE species in the cortex from 18-h fasted, 9-week-old Etnppl KO and WT mice. n = 5. Data are expressed as mean ± S.D. Represented data analyzed using Student’s two-tailed t-tests. ∗α = 0.05; ∗∗α = 0.01; ∗∗∗α = 0.001; ∗∗∗∗α = 0.0001; ns, not significant.
