Photoreceptor-specific genes are hypomethylated in photoreceptors and methylated in non-photoreceptor cells from the INL.

<p>Cells from the ONL (expressing cells) and INL (non-expressing cells) were isolated by LCM from adult mouse retina. Genomic DNA was isolated and bisulfite sequenced. % DNA methylation of photoreceptor genes was plotted versus the CpG site position (noted by hash marks) relative to the TSS (position “0”) for <i>A</i>, <i>Rbp3</i> and <i>B</i>, <i>Rho</i>. % methylation is the average of 3 animals ± SEM.
