Unraveling Histone Loss in Aging and Senescence

Sushil Kumar Dubey,
Rashmi Dubey,
Mark Ellsworth Kleinman

Abstract: As the global population experiences a notable surge in aging demographics, the need to understand the intricate molecular pathways exacerbated by age-related stresses, including epigenetic dysregulation, becomes a priority. Epigenetic mechanisms play a critical role in driving age-related diseases through altered gene expression, genomic instability, and irregular chromatin remodeling. In this review, we focus on histones, a central component of the epigenome, and consolidate the key findings of histone loss … Show more

“…It was also observed in the skin in a model of atopic dermatitis(Pellefigues et al ., 2019). By contrast, basophils from aged mice were characterized by an increased expression of histone variants ( H3f3b, Hist1h2bc, Hist1h4i ), known to increase during cellular senescence(Dubey, Dubey and Kleinman, 2024) as well as genes coding proteins with anti-inflammatory properties such as thymosin β4 ( Tmsb4x ), peroxiredoxin 5 ( Prdx5 ) (Philp and Kleinman, 2010; Knoops et al ., 2011) or IκBα ( Nfkbia ) (Pellefigues, Mehta, et al ., 2021). They also expressed more coactosin-like protein ( Ctl1 ), a chaperone stabilizing lipoxygenase activity (Basavarajappa et al ., 2014), CD16 ( Fcgr3 ), known to be expressed by a minor subset of basophils in human blood(Vivanco Gonzalez et al ., 2020), and Il18rap , coding for a chain of the IL-18 receptor.…”
