Figure 1 A schematic diagram of CpG sites in the FST promoter and 5′-UTR region. CpG sites are depicted by lollipop markers. Primer-binding sites targeted in this study are shown below the diagram. → Represents forward primers and ← represents reverse primers. The number of lollipop markers is not indicative of detected CpG sites: 140 CpG sites were identified in the FST promoter and 5′-UTR region.
