Quantitative analysis of follistatin (FST) promoter methylation in peripheral blood of patients with polycystic ovary syndrome Qing Sang, Shaozhen Zhang, Shien Zou, Huan Wang, Ruizhi Feng, Qiaoli Li, Li Jin, Lin He, Qinghe Xing, Lei Wang Reproductive BioMedicine Online Volume 26, Issue 2, Pages 157-163 (February 2013) DOI: 10.1016/j.rbmo.2012.10.011 Copyright © 2012 Reproductive Healthcare Ltd.

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.
