Figure 6. Regulation of scleral muscarinic
receptor subtype gene expression during myopia development. The
regulation of the five mAChRs was assessed in the tree shrew
sclera using real-time PCR and the DNA-binding dye, SYBR green I. Data
was calculated relative to the housekeeping gene, HPRT, and
expressed relative to the contralateral control eye (for myopic groups)
or left/right eyes (for normal groups). Data are shown as the mean
percentage change±SEM (n=5 for 5 day myopia data, 1 day myopia and
normal data, n=6).
