Advancing the molecular knowledge surrounding fertility and inheritance has become critical given halving of sperm counts in last 40 years, rise complex disease which cannot be explained by genetics alone. The connection between both these trends may lie alterations to epigenome occur through environmental exposures. Changes are also associated with health risks across generations such as metabolic disorders cancer. Thus, it is imperative identify epigenetic modifications that escape reprogramming during spermatogenesis embryogenesis. Here, we aimed chromatin signature(s) involved transgenerational phenotypes our genetic mouse model overexpresses histone demethylase KDM1A their germ cells. We used sperm-specific immunoprecipitation followed depth sequencing (ChIP-seq), computational analysis whether differential enrichment H3 lysine 4 trimethylation (H3K4me3), 27 (H3K27me3) serve mechanisms for paternal germline. Our on transgenic males revealed specific changes H3K4me3 predominantly occurred independently from bivalent H3K4me3/H3K27me3 regions. Many regions altered were identified allele pre-implantation embryo. These findings suggest functions transmission non-genetic transgenerationally.

PIWI-interacting RNAs (piRNAs) and their associated PIWI clade Argonaute proteins constitute the core of piRNA pathway. In gonadal cells, this conserved pathway is crucial for genome defense, its main function to silence transposable elements. This achieved through posttranscriptional transcriptional gene silencing. Precursors that give rise piRNAs require specialized transcription transport machineries because biogenesis a cytoplasmic process. The ping-pong cycle, silencing mechanism, combines cleavage-dependent transposon with production. also in nucleus, where they scan nascent target transcripts sequence complementarity, instructing deposition repressive chromatin marks at loci. Although studies have revealed numerous factors participate each branch pathway, precise molecular roles these often remain unclear. review, we summarize our current understanding mechanisms involved function.

The development of animal embryos is initially directed by maternal gene products. Then, during the maternal-to-zygotic transition (MZT), developmental control handed to zygotic genome. Extensive research in both vertebrate and invertebrate model organisms has revealed that MZT can be subdivided into two phases, which very different modes regulation are implemented: initially, exclusively post-transcriptional post-translational, following gradual activation genome leads predominance transcriptional regulation. These changes expression program precisely controlled highly interconnected. Here, we review current understanding mechanisms underlie handover MZT.

Abstract Aberrant metabolism is the root cause of several serious health issues, creating a huge burden to and leading diminished life expectancy. A dysregulated induces secretion molecules which in turn trigger inflammatory pathway. Inflammation natural reaction immune system variety stimuli, such as pathogens, damaged cells, harmful substances. Metabolically triggered inflammation, also called metaflammation or low-grade chronic consequence synergic interaction between host exposome—a combination environmental drivers, including diet, lifestyle, pollutants other factors throughout span an individual. Various levels inflammation are associated with lifestyle-related diseases diabetes, obesity, metabolic fatty liver disease (MAFLD), cancers, cardiovascular disorders (CVDs), autoimmune diseases, lung diseases.
