Figure 9. Expression of selected
genes in rat retina as measured by quantitative reverse
transcriptase PCR (qRT–PCR). Retinas were harvested from rats
maintained under cyclic dim or bright light exposure for eight
weeks. Expression values were normalized with the housekeeping
gene, Rpl19. Expression values (±SD) are presented as
fold change over the CONT+DL value, which was set to 1.0 (n=4
samples). CONT+DL: control diet under cyclic dim light; caffeic
acid phenethyl ester (CAPE)+DL: CAPE diet under cyclic dim
light; CONT+BL: control diet under cyclic bright light; CAPE+BL:
CAPE diet under cyclic bright light. (*: p<0.05, with the
Student t test).
