A groundbreaking study from the Universidad del País Vasco (UPV-EHU) reveals the placenta’s critical role as an intermediary in genetic risk, emphasizing the importance of DNA methylation during gestation and its connection to neuropsychiatric disorders.
The Placenta: Key to fetal Progress
During pregnancy, the fetus spends approximately 40 weeks enveloped by the placenta, an organ vital for its development and survival. Factors such as nutrition, maternal stress, and exposure to contaminants influence the baby’s well-being, as do hereditary factors. The study by the Universidad del País Vasco (UPV-EHU) and the Instituto de Investigación Sanitaria Biobizkaia (IIS Biobizkaia) has discovered how, during gestation, the placenta can modify the fetus’s DNA through a process known as methylation.

Dr. Nora Fernández-Jiménez, the study’s coordinator, explains that DNA methylation involves chemical modifications affecting gene function without altering its sequence.Son como unos ‘adornitos’ que se le ponen a la molécula de ADN y cambian la función génica
,she details,describing these modifications as akin to “little decorations” on the DNA molecule that alter gene function. This modification is linked to an increased genetic risk of developing conditions such as schizophrenia, bipolar disorder, and depression, as well as, to a lesser extent, ADHD and autism.
Cataloging Chemical Modifications and Their Health Impact
Researchers have created a catalog of chemical modifications associated with DNA methylation, linking it to genetic data from various neuropsychiatric diseases. Their findings suggest possibly causal associations between methylation and the development of these conditions. This discovery opens new avenues for treating psychiatric symptoms even before birth, using a personalized and preventive medicine approach.
A Promising Future in Preventive Medicine
With this advancement, experts believe it is possible to intervene during gestation to reduce the risk of psychiatric illnesses. Dr. Fernández-Jiménez emphasizes the finding’s relevance as an chance to improve an individual’s future health, focusing on approaches based on DNA methylation. this study marks the beginning of deeper investigations into the placenta’s role in genetic regulation and its impact on human development.
Epigenetic Regulation and Placental Development
In related news,a study published on February 6,2025,delves into epigenetic regulation through placental DNA methylation,offering fresh insights into the connection between this process and pregnancy and embryonic development disorders. The research identifies a crucial protein that, along with other enzymes, restores partially methylated domains in human trophoblast stem cells, playing a key role in placental development.
The placental methylome, or the collection of placental DNA methylation patterns, is a unique epigenetic signature of the placenta, characterized by partially methylated domains. This pattern is highly conserved among mammals and shares similarities with methylomes observed in many types of cancer.
Placenta’s Role in Neuropsychiatric Disorders: Q&A
recent research has shed light on the placenta’s significant role in fetal advancement adn its potential link to neuropsychiatric disorders. This Q&A explores the key findings and implications of these studies.
What is the role of the placenta in fetal development?
The placenta is a vital organ that develops during pregnancy. It serves as the lifeline between the mother and the fetus,providing essential functions such as:
- nutrient supply: Delivering nutrients from the mother to the fetus.
- oxygen transport: Transferring oxygen from the mother’s blood to the fetal blood.
- Waste removal: Eliminating waste products from the fetal blood.
- Hormone production: Producing hormones necessary for maintaining the pregnancy.
The placenta essentially supports the fetus’s growth and survival throughout the approximately 40 weeks of gestation.
How dose the placenta influence the risk of neuropsychiatric disorders?
According to a recent study from the universidad del País Vasco (UPV-EHU) and the Instituto de investigación sanitaria biobizkaia (IIS Biobizkaia), the placenta can modify the fetus’s DNA through a process called DNA methylation. This modification, likened to “little decorations” on the DNA molecule, can alter gene function and potentially increase the risk of developing neuropsychiatric conditions. Specifically, the study suggests a link between placental DNA methylation and an increased genetic risk of conditions such as schizophrenia, bipolar disorder, depression, ADHD, and autism.
What is DNA methylation and why is it crucial?
DNA methylation is a chemical modification that affects gene function without altering the DNA sequence itself. It’s a crucial epigenetic mechanism that plays a role in:
- Gene expression: Influencing whether a gene is turned on or off.
- Development: Guiding the development of cells and tissues.
- Disease susceptibility: Contributing to the risk of various diseases.
In the context of the placenta, DNA methylation can be influenced by factors such as maternal nutrition, stress, and exposure to contaminants, ultimately affecting the fetus’s development and health.
Can interventions during pregnancy reduce the risk of psychiatric disorders in the child?
The study suggests that early intervention during gestation, focusing on approaches based on DNA methylation, might hold promise for reducing the risk of psychiatric illnesses. By understanding how placental DNA methylation influences fetal development, experts beleive it may become possible to develop personalized and preventive medicine approaches to improve an individual’s future health.
What are partially methylated domains (PMDs) in the placenta?
Partially methylated domains (PMDs) are regions within the placental methylome (the collection of DNA methylation patterns) that exhibit incomplete methylation. These PMDs are a unique epigenetic signature of the placenta and are highly conserved among mammals. interestingly, similar methylomes with PMDs are also observed in many types of cancer.
What role does the recently identified protein play in placental development?
A study published on February 6,2025,identified a crucial protein that,along with other enzymes,restores partially methylated domains in human trophoblast stem cells.This protein plays a key role in epigenetic regulation during placental development and could provide fresh insights into pregnancy and embryonic development disorders.
