Emerging evidence that the mammalian sperm epigenome serves as a template for embryo development

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: April 14, 2023

Abstract Although more studies are demonstrating that a father’s environment can influence child health and disease, the molecular mechanisms underlying non-genetic inheritance remain unclear. It was previously thought sperm exclusively contributed its genome to egg. More recently, association have shown various environmental exposures including poor diet, toxicants, stress, perturbed epigenetic marks in at important reproductive developmental loci were associated with offspring phenotypes. The cellular routes underlie how transmitted fertilization, resist reprogramming embryo, drive phenotypic changes only now beginning be unraveled. Here, we provide an overview of state field intergenerational paternal mammals present new insights into relationship between embryo development three pillars inheritance: chromatin, DNA methylation, non-coding RNAs. We evaluate compelling evidence sperm-mediated transmission retention embryo. Using landmark examples, discuss sperm-inherited regions may escape impact via implicate transcription factors, chromatin organization, transposable elements. Finally, link paternally functional pre- post-implantation Understanding factors will permit greater understanding related origins disease.

Ferroptosis Induced by Pollutants: An Emerging Mechanism in Environmental Toxicology

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(5), P. 2166 - 2184

Published: Jan. 26, 2024

Environmental pollutants have been recognized for their ability to induce various adverse outcomes in both the environment and human health, including inflammation, apoptosis, necrosis, pyroptosis, autophagy. Understanding these biological mechanisms has played a crucial role risk assessment management efforts. However, recent identification of ferroptosis as form programmed cell death emerged critical mechanism underlying pollutant-induced toxicity. Numerous studies demonstrated that fine particulates, heavy metals, organic substances can trigger ferroptosis, which is closely intertwined with lipid, iron, amino acid metabolism. Given growing evidence linking severe diseases such heart failure, chronic obstructive pulmonary disease, liver injury, Parkinson's Alzheimer's cancer, it imperative investigate ferroptosis. In this review, we comprehensively analyze pathways intricate signaling molecules elucidate integration into driving braking axes. Furthermore, discuss potential hazards associated organs four representative animal models. Finally, provide an outlook on future research directions strategies aimed at preventing By enhancing our understanding novel developing effective preventive measures, mitigate effects environmental safeguard health.

The discovery of a pathogenic variant in the alpha-synuclein (SNCA) gene Contursi kindred 1997 indisputably confirmed genetic cause subset Parkinson’s disease (PD) patients. Currently, variants one seven established PD genes or strongest known risk factor gene, GBA1, are identified ∼15% patients unselected for age at onset and family history. In this Debate article, we highlight multiple avenues research that suggest an important - some cases even predominant role genetics aetiology, including familial clustering, high rates monogenic selected populations, complete penetrance with certain forms. At first sight, steep increase prevalence exceeding other neurodegenerative diseases may argue against etiology. Notably, principal contribution is conferred by LRRK2 GBA1 and, both cases, characterized overall late age-related penetrance. addition, polygenic plays considerable PD. However, it likely that, majority patients, complex interplay aging, genetic, environmental, epigenetic factors leads to development.

Redox regulation: mechanisms, biology and therapeutic targets in diseases

Signal Transduction and Targeted Therapy, Journal Year: 2025, Volume and Issue: 10(1)

Published: March 7, 2025

Redox signaling acts as a critical mediator in the dynamic interactions between organisms and their external environment, profoundly influencing both onset progression of various diseases. Under physiological conditions, oxidative free radicals generated by mitochondrial respiratory chain, endoplasmic reticulum, NADPH oxidases can be effectively neutralized NRF2-mediated antioxidant responses. These responses elevate synthesis superoxide dismutase (SOD), catalase, well key molecules like nicotinamide adenine dinucleotide phosphate (NADPH) glutathione (GSH), thereby maintaining cellular redox homeostasis. Disruption this finely tuned equilibrium is closely linked to pathogenesis wide range Recent advances have broadened our understanding molecular mechanisms underpinning dysregulation, highlighting pivotal roles genomic instability, epigenetic modifications, protein degradation, metabolic reprogramming. findings provide foundation for exploring regulation mechanistic basis improving therapeutic strategies. While antioxidant-based therapies shown early promise conditions where stress plays primary pathological role, efficacy diseases characterized complex, multifactorial etiologies remains controversial. A deeper, context-specific signaling, particularly redox-sensitive proteins, designing targeted aimed at re-establishing balance. Emerging small molecule inhibitors that target specific cysteine residues proteins demonstrated promising preclinical outcomes, setting stage forthcoming clinical trials. In review, we summarize current intricate relationship disease also discuss how these insights leveraged optimize strategies practice.
