Deficit in GSH levels in brain (anterior cortex) of GCLM −/− relative to +/+ mice at different ages

	5–6 days old	16–20 days old	35–40 days old	3 months old
Percent GSH in GCLM −/− relative to +/+ mice	17 ± 2	31 ± 1	31 ± 3	28 ± 2

Brain total GSH deficit in GCLM −/− mice. The GSH deficit is expressed as percent of GSH levels in GCLM −/− mice relative to those in +/+ mice. GSH measurements have been performed in at least four mice per genotype and per age. Data are presented by mean ± SEM.
