Western Blot analyses for T1-alpha (T1α) and surfactant protein C (SP–C) in glutathione reductase-deficient (Gsr-KO) and -sufficient (Gsr-WT) mouse lungs. (A) Independent effects of genotype and day of life on lung T1α expression and an interaction between day of life and genotype were detected. (B) No effects or interactions were detected. Data are expressed as mean +SEM (n=3) and were assessed by two-way ANOVA followed by Newman-Keuls post hoc. P < 0.05 *vs E19-Gsr-WT, #vs PND14 Gsr-WT, &vs PND28-Gsr-WT, ∧vs PND70-Gsr-WT, %vs E19-Gsr-KO, @vs PND14-Gsr-KO.
