mRNA status of different types of FA desaturase (A) and antioxidant (B) genes in WT, KO, and OE cells. Measurements of gene transcript abundance was analyzed by using quantitative RT-PCR as detailed under ”Experimental Procedures.” ΔSLD, sphingolipid Δ4 desaturase (LmjF.26.1690); Δ12FAD, Δ12 fatty acid desaturase (LmjF.10.0010); Δ12FAD1, Δ12 fatty acid desaturase (LmjF.33.3270); Δ9FAD, Δ9 fatty acid desaturase (LmjF.24.2250); Δ5FAD, Δ5 fatty acid desaturase (LmjF.07.1090); Δ6FAD, Δ6 fatty acid desaturase (LmjF.36.6950); Δ4FAD, Δ4 fatty acid desaturase (LmjF.14.1340). SOD (LmjF.30.2770); APX, ascorbate peroxidase (LmjF.34.0070); GAPDH (LmjF.30.2980); NUOR, NADH-ubiquinone oxidoreductase (LmjF.05.0980); TR, trypanothione reductase (LmjF.05.0350); GPX, non-selenium glutathione peroxidase (LmjF.26.0810); TPX, tryparedoxin peroxidase (LmjF.15.1120). All data were normalized using 18 S rRNA as the endogenous control. Data show the mean ± S.D. of three independent experiments. * p, 0.05, compared with WT sample. All the data are representative of three independent transfection experiments.
