まとめ
Maternal antenatal depression is linked to offspring DNA hypomethylation in middle childhood, particularly at cg06112204 in the MAD1L1 gene. This finding offers insights into the long-term epigenetic effects of prenatal depression.
科学分野:
- Epigenetics
- Developmental Psychology
- Maternal Health
背景:
- Limited research exists on the connection between antenatal depression and offspring DNA methylation.
- Existing studies show inconsistent findings regarding this association.
研究 の 目的:
- To rigorously investigate the association between maternal antenatal depression and offspring DNA methylation.
- To examine these epigenetic alterations in both neonatal and middle childhood periods (8-10 years).
主な方法:
- Maternal antenatal depression was identified using diagnosis codes and self-reported symptoms.
- Offspring DNA methylation was measured from dried blood spots (neonatal) and venous blood (middle childhood).
主要な成果:
- No significant DNA methylation changes were found in the neonatal period after FDR correction.
- In middle childhood, antenatal depression was associated with hypomethylation at two CpG sites: cg06112204 (MAD1L1) and cg17830140 (POLRMT).
- These associations remained significant even after controlling for postnatal depression.
結論:
- The hypomethylation of cg06112204 in offspring is credibly linked to maternal antenatal depression.
- Prior research supports the association between MAD1L1 gene methylation and depression phenotypes in older age groups.

Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...

Depressant drugs, including alcohol and sedative-hypnotics, diminish central nervous system activity by enhancing the action of gamma-aminobutyric acid (GABA), a neurotransmitter that reduces brain activity and promotes relaxation. These substances can have various therapeutic uses but also pose significant risks, especially when misused or combined.
Alcohol is a common depressant that can induce a sense of relaxation and reduced inhibition at low doses. Contrary to its occasional...

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.

01:18Depression: Overview

Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...
