Figure 5. Methylation percentages of cytosine-phosphate-guanine (CpG) sites in the collagen type Iα1 promoter region in scleras of monocular deprivation and control eyes after four weeks of monocular deprivation and one week of recovery. Numbers in parentheses on the x-axis are the locations of the cytosine-phosphate-guanine (CpG) sites. Methylation at site 11 was significantly less in the monocular deprivation–recovery (MD-R) eyes than in the NC₅₈ eyes. MD-R: after 7 days of recovery following 4 weeks of monocular deprivation, MD-RC: contralateral control eyes, NC₅₈: age-matched normal control eyes for MD recovery, *, p<0.05.
