概括

在子宫内膜异位症中,HOXA11-antisense长非编码RNA (HOXA11-AS) 的含量升高,并且在孕激素治疗期间抑制它可能会阻止疾病的生长. 在子宫外病变和孕激素治疗后观察到较低的HOXA11-AS表达.

科学领域:

内分泌学和生殖生物学
分子生物学分子生物学
遗传学是一个遗传学.

背景情况:

子宫内膜异位症是一种复杂的妇科病症,其特点是子宫外存在子宫内膜状组织.
长非编码RNAs (lncRNAs) 在基因调节和细胞过程中起着至关重要的作用,新出现的证据表明它们与子宫内膜异位症病理生理学有关.
HOXA11-antisense长非编码RNA (HOXA11-AS) 已涉及子宫内膜发育,但其在子宫内膜异位症和治疗反应中的具体作用仍未完全阐明.

研究的目的:

研究HOXA11-AS在子宫内膜异位症中的表达和功能作用.
确定孕激素治疗对子宫内膜异位症妇女HOXA11-AS水平的影响.
探索由HOXA11-AS在子宫内膜细胞中调节的下游目标.

主要方法:

定量实时聚合酶连锁反应 (RT-qPCR) 用于测量孕激素治疗前后的子宫内膜异位和子宫内膜异位内膜组织中的HOXA11-AS水平.
来自子宫内膜异位症患者 (ENDO细胞系) 的不朽化子宫内膜层细胞用HOXA11-AS等离子体被转染,以过度表达lncRNA.
在HOXA11-AS过度表达后,通过RT-qPCR分析了参与细胞增殖,瘤发生和细胞亡的潜在向基因的表达.

主要成果:

孕激素治疗显著降低了HOXA11-AS表达,在异位子宫内膜病变中观察到的最明显的减少 (81%低于异位子宫内膜病变).
在子宫内膜细胞系中HOXA11-AS的过度表达导致了与细胞增殖和瘤发生相关的基因表达的显著增加 (ITGB3,AKT1,MMP2,MMP9).
增加HOXA11-AS表达也提高了瘤抑制剂和亡调节基因的mRNA水平,包括PTEN,BCL2和Caspase3.

结论:

HOXA11-AS被确定为正常子宫内膜发育中的关键调节剂,在子宫内膜异位症中异常升高,导致其病理生理学.
在孕激素治疗期间观察到的HOXA11-AS的减少表明,其抑制在抑制子宫内膜异位症生长和侵袭方面发挥着关键作用.
HOXA11-AS影响了对疾病进展至关重要的多个基因的表达,突出了其作为治疗点的潜力.

关键词:

A Syngeneic Murine Model of Endometriosis using Naturally Cycling Mice

Many rodent models of endometriosis are limited by technical complexity, reproducibility, and/or need for immunocompromised animals or special reporter mice. We present a simplified system of lesion induction using any experimental mouse with an independently verifiable, objective scoring system and with no requirement for ovariectomy or survival...

Nucleic acids

Nucleic acids

Nucleic acids are the most important macromolecules for the continuity of life. They carry the cell's genetic blueprint and carry instructions for its functioning.
DNA and RNA
The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is in the nucleus of eukaryotes and in the organelles, chloroplasts, and mitochondria. In prokaryotes,...

Detection of circulating ribonucleic acid (cRNA) from blood is an unmet need in clinical diagnostics. Here we describe methods that characterize cRNA from non-small cell lung cancer patients using sensitive and specific digital polymerase chain reaction. The tests meet design requirements to detect fusion variants within 72...
