精神分裂症 (SCZ) 缺乏客观的诊断标记. 这项研究确定了三个上调循环RNA (circRNAs) hsa_circ_0006157,hsa_circ_0071422和hsa_circ_0071095 作为SCZ的潜在诊断指标.
科学领域:
- 基因组学就是基因组学.
- 分子生物学分子生物学
- 精神病学是一个精神病学.
背景情况:
- 精神分裂症 (SCZ) 的发病过程复杂,缺乏客观的诊断指标.
- 全转录组分析为早期诊断标记物发现提供了潜在的机会.
- 在SCZ中循环RNAs (circRNAs) 的作用在很大程度上仍未被探索.
研究的目的:
- 在SCZ患者的外周血液中研究差异表达的circRNAs.
- 为了确定SCZ.潜在的基于circRNA的诊断标记物.
- 探索涉及SCZ中circRNAs的调节网络.
主要方法:
- 来自5名SCZ患者和5名对照患者的周围血液的全转录组分析.
- 基因本体学 (GO) 和基因和基因组的京都百科全书 (KEGG) 路径分析.
- 预测竞争的内源RNA (ceRNA) 网络,蛋白-蛋白相互作用和circRNA-RNA结合蛋白 (RBP) 相互作用.
- 定量实时PCR (qRT-PCR) 用于循环RNA表达的验证.
主要成果:
- 分析了38,699个circRNA,确定了589个差异表达的circRNA (DEcircRNA).
- DEcircRNAs的宿主基因与TNF和Wnt信号通路有关.
- 构建了一个ceRNA网络;在SCZ患者中确定了三个显著上调的DEcircRNA (hsa_circ_0006157,hsa_circ_0071422,hsa_circ_0071095).
- 确定了27个RBP与DEcircRNAs结合,包括显著表达的DDX54和RBM15B.
结论:
- 上调的circRNAs hsa_circ_0006157,hsa_circ_0071422和hsa_circ_0071095显示出作为SCZ潜在的诊断标记物的希望.
- 需要进一步的功能研究来确认这些circRNAs在SCZ病变发生中的确切作用.
