Article Abstract
To examine whether chronic physical aggression (CPA) in adulthood can be epigenetically programmed early in life due to exposure to early-life adversity. Literature search of public databases such as PubMed/MEDLINE and Scopus. Children/adolescents susceptible for CPA and exposed to early-life abuse fail to efficiently cope with stress that in turn results in the development of CPA later in life. This phenomenon was observed in humans and animal models of aggression. The susceptibility to aggression is a complex trait that is regulated by the interaction between environmental and genetic factors. Epigenetic mechanisms mediate this interaction. Subjects exposed to stress early in life exhibited long-term epigenetic programming that can influence their behaviour in adulthood. This programming affects expression of many genes not only in the brain but also in other systems such as neuroendocrine and immune. The propensity to adult CPA behaviour in subjects experienced to early-life adversity is mediated by epigenetic programming that involves long-term systemic epigenetic alterations in a whole genome.

As essential sources of vegetables, oilseeds, and forage, Brassica crops exhibit complex epigenetic regulation mechanisms involving histone modifications, DNA modifications, RNA modifications, noncoding RNAs, and chromatin remodelling. The agronomic traits and environmental adaptability of crops are regulated by both genetic and epigenetic mechanisms, while epigenetic variation can affect plant phenotypes without changing gene sequences. Furthermore, the impact of epigenetic modifications on plant phenotype has accelerated the crop breeding process.

Monocyte-derived macrophages (mo-macs) often drive immunosuppression in the tumour microenvironment (TME) and tumour-enhanced myelopoiesis in the bone marrow fuels these populations. Here we performed paired transcriptome and chromatin accessibility analysis over the continuum of myeloid progenitors, circulating monocytes and tumour-infiltrating mo-macs in mice and in patients with lung cancer to identify myeloid progenitor programs that fuel pro-tumorigenic mo-macs. We show that lung tumours prime accessibility for Nfe2l2 (NRF2) in bone marrow myeloid progenitors as a cytoprotective response to oxidative stress, enhancing myelopoiesis while dampening interferon response and promoting immunosuppression.

Cell type-specific regulatory programs that drive type 1 diabetes (T1D) in the pancreas are poorly understood. Here, we performed single-nucleus multiomics and spatial transcriptomics in up to 32 nondiabetic (ND), autoantibody-positive (AAB), and T1D pancreas donors. Genomic profiles from 853,005 cells mapped to 12 pancreatic cell types, including multiple exocrine subtypes.

Triple-negative breast cancers (TNBCs) lack predictive biomarkers to guide immunotherapy, especially during early-stage disease. To address this issue, we used single-cell RNA sequencing, bulk transcriptomics, and pathology assays on samples from 171 patients with early-stage TNBC receiving chemotherapy with or without immunotherapy. Our investigation identified an enriched subset of interferon (IFN)-induced CD8 T cells in early TNBC samples, which predict immunotherapy nonresponsiveness.

Human cytomegalovirus (HCMV) infects up to 80% of the world's population. Here, we show that HCMV infection leads to widespread changes in human chromatin accessibility and chromatin looping, with hundreds of thousands of genomic regions affected 48 hr after infection. Integrative analyses reveal HCMV-induced perturbation of Hippo signaling through drastic reduction of TEAD1 transcription factor activity.
