Adverse childhood experience is a major risk factor for the onset of depression in adulthood. Neuroinflammation characterized by microglial activation and cytokine secretion is involved in susceptibility to depression induced by early life stress. Jumonji domain-containing protein 3 (Jmjd3), a trimethylated lysine 27 in histone 3 (H3K27me3) demethylase, can be activated by nuclear factor-kappa B (NF-κB), further regulating the expression of pro-inflammatory cytokines and resulting in neuroinflammation. However, its involvement in susceptibility to early life stress-related depression is unknown. In the current study, maternal separation (MS) was utilized as a model of early life stress and systemic lipopolysaccharide (LPS) administration in adulthood was used as a later-life challenge. Depressive- and anxiety-like behaviors and memory impairment were detected by behavioral tests. Microglial activation, pro-inflammatory cytokine expression, and NF-κB, Jmjd3, and H3K27me3 expression were detected in the prefrontal cortex and hippocampus in both infant and adult rats. Meanwhile, the Jmjd3 inhibitor GSK-J4 was used as an intervention in vivo and in vitro. Our results showed that MS induced depression-like behaviors and synchronously caused microglial activation, pro-inflammatory cytokine over-expression, NF-κB and Jmjd3 over-expression, and decreased H3K27me3 expression in infant rats. All these alterations could also be detected in adulthood. Seven-day LPS administration in adult rats induced similar changes of behaviors and biomarkers. Interestingly, compared with rats not exposed to MS, MS-exposed rats receiving LPS administration developed more severe depression-like behaviors and neuroinflammatory status, higher levels of NF-κB and Jmjd3 expression, and lower levels of H3K27me3 expression. In addition, LPS induced microglial activation, pro-inflammatory cytokine expression and increased Jmjd3 expression in vitro. Furthermore, GSK-J4 treatment alleviated these alterations in vivo and in vitro. Thus, our data indicate that Jmjd3 is involved in the susceptibility to depression induced by MS via enhancement of neuroinflammation in the prefrontal cortex and hippocampus of rats. This study involved multiple reactions and reactants, such as Ethyl 3-((6-(4,5-dihydro-1H-benzo[d]azepin-3(2H)-yl)-2-(pyridin-2-yl)pyrimidin-4-yl)amino)propanoate (cas: 1373423-53-0Name: Ethyl 3-((6-(4,5-dihydro-1H-benzo[d]azepin-3(2H)-yl)-2-(pyridin-2-yl)pyrimidin-4-yl)amino)propanoate).
Ethyl 3-((6-(4,5-dihydro-1H-benzo[d]azepin-3(2H)-yl)-2-(pyridin-2-yl)pyrimidin-4-yl)amino)propanoate (cas: 1373423-53-0) belongs to pyrimidine derivatives. The pyrimidine derivatives can easily interact with enzymes, genetic materials, and bio components within the cell. For example, the neurotoxin tetrodotoxin is a pyrimidine derivative. It is found in a number of species including the Japanese puffer fish, the blue-ringed octopus, and the orange-bellied newt. Tetrodotoxin prevents the transmission of nerve signals and can result in paralysis and death.Name: Ethyl 3-((6-(4,5-dihydro-1H-benzo[d]azepin-3(2H)-yl)-2-(pyridin-2-yl)pyrimidin-4-yl)amino)propanoate
