Summary of the effect of vitamin C treatment on the gene expression of primary mouse embryonic fibroblasts as determined by gene expression microarray analysisa.

aThe passage 4 primary embryonic fibroblasts were treated with 20 µM ascorbate 2-phosphate for 2 days before RNA harvesting. The gene expression level in the vitamin C-treated primary MEF was divided by the level in the untreated primary MEF to obtain the fold change.bVitamin C treatment significantly affected the expression of these probes/genes. Multiple probes may be used to quantify the expression of the same gene. The number in the parenthesis represents the number of genes affected.cp value shown is Benjamini.
