Here we demonstrate the importance of these miRNA changes by showing that restoring miR-34c levels in PIEs derived from CSI stressed males prevents elevated anxiety and defective sociability normally found specifically in their adult female offspring. It also restores, at least partially, levels of sperm miR-34/449 normally reduced in their male offspring who transmit these sex-specific traits to their offspring. Strikingly, these experiments also revealed that inducing miR-34c levels in PIEs enhances the expression of its own gene and that of miR-449 in these cells. The same induction of embryo miR-34/449 gene expression likely occurs after sperm-derived miR-34c is introduced into oocytes upon fertilization. Thus, suppression of this miRNA amplification system when sperm miR-34c levels are reduced in CSI stressed mice can explain how a comparable fold-suppression of miR-34/449 levels can be found in PIEs derived from them, despite sperm containing ~50-fold lower levels of these miRNAs than those already present in PIEs. We previously found that men exposed to early life trauma also display reduced sperm levels of miR-34/449. And here we show that miR-34c can also increase the expression of its own gene, and that of miR-449 in human embryonic stem cells, suggesting that human PIEs derived from men with low sperm miR-34/449 levels may also contain this potentially harmful defect.","PeriodicalId":11767,"journal":{"name":"Epigenetics","volume":"19 1","pages":"2346694"},"PeriodicalIF":3.7,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11093028/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140916317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the effects of acute MK-801 exposure on brain gene expression at the translation level remain unclear. Here, we conducted ribosome profiling analysis on the prefrontal cortex (PFC) of acute MK-801-exposed juvenile male mice. We found 357 differentially translated genes, with the N4-acetylcytidine (ac4C) consensus motif enriched in the transcripts with increased translation efficiency. Acetylated RNA immunoprecipitation sequencing revealed 148 differentially acetylated peaks, of which 121 were hyperacetylated, and 27 were hypoacetylated. Genes harbouring these peaks were enriched in pathways related to axon guidance, Hedgehog signalling pathway, neuron differentiation, and memory. Grin2a encodes an NMDA receptor subunit NMDAR2A, and its human orthologue is a strong susceptibility gene for schizophrenia. Grin2a mRNA was hyperacetylated and exhibited significantly increased translation efficiency. NMDAR2A protein level was increased in MK-801-exposed PFC. Pretreatment of Remodelin, an inhibitor of N-acetyltransferase 10, returned the NMDAR2A protein levels to normal and partially reversed schizophrenia-like behaviours of MK-801-exposed mice, shedding light on the possible role of mRNA acetylation in the aetiology of schizophrenia.","PeriodicalId":11767,"journal":{"name":"Epigenetics","volume":"19 1","pages":"2417158"},"PeriodicalIF":2.9,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11520555/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142497364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, MeRIP-seq was performed on macrophages and Hcy-treated macrophages. GO and KEGG analyses were used to perform functional analysis of differentially methylated genes. qRT-PCR and western blot were taken to determine the expression of CD209, CD163L1, proinflammatory, and anti-inflammatory factors. Flow cytometry was used to detect the proportion of M2 macrophages. The results showed that after Hcy treatment, the overall m6A methylation of macrophages was down-regulated, and 856 differential methylation peaks were annotated to 781 genes. These included CD209 and CD163L1, whose m6A methylation was inhibited after treatment with Hcy. In addition, mRNA and protein expressions of CD209 and CD163L1 were also inhibited after Hcy treatment.

Pb exposure effects on piRNA expression and associated gene repression in the germline (testis/ovary) and soma (liver and brain) were evaluated.

In the discovery analysis, 169 twins were used to prioritize probes and test associations with DNA methylation age acceleration, and 56 independent monozygotic (MZ) twin pairs (112 individuals) were used in a within-family replication analysis. Among the 837,274 sites analyzed, no probe sites were statistically significant at the genome-wide level (p < 5.97 × 10-8), but 25 suggestive sites (p < 5 × 10-5) were annotated to genes related to various biological processes, including inflammatory response and protein-binding functions that extend prior findings. The nominal associations at these suggestive probe sites were highly correlated (r = .72) between the discovery sample and the MZ pair replication sample.
