ADVANCED SCIENCE (WEINHEIM, BADEN-WURTTEMBERG, GERMANY) 2024; 11:e2306486. [PMID: 38588050 DOI: 10.1002/advs.202306486] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Revised: 02/20/2024] [Indexed: 04/10/2024]
Abstract
Nucleosome assembly proteins (NAPs) have been identified as histone chaperons. Testis-Specific Protein, Y-Encoded-Like (TSPYL) is a newly arisen NAP family in mammals. TSPYL2 can be transcriptionally induced by DNA damage and TGFβ causing proliferation arrest. TSPYL1, another TSPYL family member, has been poorly characterized and is the only TSPYL family member known to be causal of a lethal recessive disease in humans. This study shows that TSPYL1 and TSPYL2 play an opposite role in TGFβ signaling. TSPYL1 partners with the transcription factor FOXA1 and histone methyltransferase EZH2, and at the same time represses TGFBR1 and epithelial-mesenchymal transition (EMT). Depletion of TSPYL1 increases TGFBR1 expression, upregulates TGFβ signaling, and elevates the protein stability of TSPYL2. Intriguingly, TSPYL2 forms part of the SMAD2/3/4 signal transduction complex upon stimulation by TGFβ to execute the transcriptional responses. Depletion of TSPYL2 rescues the EMT phenotype of TSPYL1 knockdown in A549 lung carcinoma cells. The data demonstrates the prime role of TSPYL2 in causing the dramatic defects in TSPYL1 deficiency. An intricate counter-balancing role of TSPYL1 and TSPYL2 in regulating TGFβ signaling is also unraveled.

Abstract
Aging is a major risk factor for numerous chronic diseases. Vaccination offers a promising strategy to combat these age-related diseases by targeting specific antigens and inducing immune responses. Here, we provide a comprehensive overview of recent advances in vaccine-based interventions targeting these diseases, including Alzheimer's disease, type II diabetes, hypertension, abdominal aortic aneurysm, atherosclerosis, osteoarthritis, fibrosis and cancer, summarizing current approaches for identifying disease-associated antigens and inducing immune responses against these targets. Further, we reflect on the recent development of vaccines targeting senescent cells, as a strategy for more broadly targeting underlying causes of aging and associated pathologies. In addition to highlighting recent progress in these areas, we discuss important next steps to advance the therapeutic potential of these vaccines, including improving and robustly demonstrating efficacy in human clinical trials, as well as rigorously evaluating the safety and long-term effects of these vaccine strategies.

Abstract
Epigenetic dysregulation emerges as a critical hallmark and driving force of aging. Although still an evolving field with much to explore, it has rapidly gained significance by providing valuable insights into the mechanisms of aging and potential therapeutic opportunities for age-related diseases. Recent years have witnessed remarkable strides in our understanding of the epigenetic landscape of aging, encompassing pivotal elements, such as DNA methylation, histone modifications, RNA modifications, and noncoding (nc) RNAs. Here, we review the latest discoveries that shed light on new epigenetic mechanisms and critical targets for predicting and intervening in aging and related disorders. Furthermore, we explore burgeoning interventions and exemplary clinical trials explicitly designed to foster healthy aging, while contemplating the potential ramifications of epigenetic influences.
