概括
围产期窒息症是一种出生并发症,与健康对照组相比,在精神分裂症或双相情感障碍患者中,DNA甲基化发生的变化不同. 这种相反的表观遗传反应可能会导致这些精神疾病的风险.
科学领域:
- 神经科学是一个神经科学.
- 精神病学是一个精神病学.
- 表观遗传学 在表观遗传学中,表观遗传学是指表观遗传学.
背景情况:
- 环境暴露,如围产期窒息,可以导致表观遗传变化,导致精神分裂症和双相情感障碍.
- 围产期窒息,即出生时大脑氧气减少,与精神疾病风险增加有关.
研究的目的:
- 在患有精神分裂症或双相情感障碍的个体中调查与围产期窒息相关的DNA甲基化差异.
- 探索表观遗传修饰在精神分裂症和双相情感障碍的共同病因发生中的作用.
主要方法:
- 全表观基因组关联研究 (EWAS) 关于血液细胞中的DNA甲基化.
- 来自挪威医疗出生登记处的前性数据.
- 分析了643名患者 (精神分裂症/双极性障碍) 和676名对照人群.
主要成果:
- 发现围产期窒息暴露和DNA甲基化水平之间的相互作用.
- 健康对照组显示甲基化增加,而患者显示特定DNA区域甲基化减少.
- 不同的甲基化区域涉及对大脑发育,髓化和神经可塑性至关重要的基因 (LINGO3,BLCAP,NNAT,NANOS2,SLC2A14).
结论:
- 患者与对照者对围产期窒息的表观遗传反应相反,表明精神疾病风险的分子机制.
- 这些发现支持表观遗传修饰在精神分裂症和双相情感障碍的共享途径中的作用.

Human Genetics
572
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

Genomic Imprinting and Inheritance
34.5K
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

Epigenetic Regulation
3.0K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders
657
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...
