Childhood maltreatment (CM) can affect the children of those who experienced it, and the biological processes behind this are not well understood.
This study examined how maternal experiences of CM relate to the expression of microRNAs (miRNAs) in maternal and perinatal tissues by analyzing samples from 43 pregnant women.
It found that higher levels of maternal CM were linked to lower levels of a specific miRNA (hsa-miR-582-3p) in cord blood, suggesting a potential impact on the genetic development of the offspring.
Introduction: Long interspersed nuclear elements (LINEs) are endogenous retrotransposable elements. A few studies have linked the methylation pattern of LINE-1 to different mental disorders (e.g.
The protein Sirtuin-1 (SIRT1) was observed to increase in response to stress and was linked to DNA damage repair and modifications in the genome that promote melanoma progression.
Silencing SIRT1 resulted in increased expression of genes associated with tumor growth and aggressiveness, highlighting its role in malignant transformation during stressful conditions.
