Premature cellular senescence is a pivotal process in aging and age-related diseases, triggered by various stressors. However, this is not a homogeneous phenotype, but a heterogeneous cellular state composed of multiple senescence programs with different compositions. Therefore, understanding the complex dynamics of senescence programs requires a systemic approach. We introduce PseudoCell, a multivalued logical regulatory network designed to explore the molecular intricacies of premature senescence.
PseudoCell integrates key senescence signaling pathways and molecular mechanisms, offering a versatile platform for investigating diverse premature senescence programs initiated by different stimuli.
Validation through simulation of classical senescence programs, including oxidative stress-induced senescence and oncogene-induced senescence, demonstrates its ability to replicate molecular signatures consistent with empirical data. Additionally, we explore the role of CCL11, a novel senescence-associated molecule, through simulations that reveal potential pathways and mechanisms underlying CCL11-mediated senescence induction.
In conclusion, PseudoCell provides a systematic approach to dissecting premature senescence programs and uncovering novel regulatory mechanisms.
细胞过早衰老由多种应激源触发,是衰老及与年龄相关疾病中的关键过程。然而,这并非一种均一的表型,而是由具有不同组成的多个衰老程序构成的异质性细胞状态。因此,理解衰老程序的复杂动态需要一种系统方法。我们引入了PseudoCell,这是一个多值逻辑调控网络,旨在探索过早衰老的分子复杂性。
PseudoCell整合了关键衰老信号通路和分子机制,为研究由不同刺激引发的多种过早衰老程序提供了一个通用平台。
通过对经典衰老程序(包括氧化应激诱导的衰老和癌基因诱导的衰老)进行模拟验证,证明了其复制与实验数据一致的分子特征的能力。此外,我们通过模拟探索了一种新型衰老相关分子CCL11的作用,这些模拟揭示了CCL11介导衰老诱导的潜在途径和机制。
总之,PseudoCell为剖析过早衰老程序和揭示新的调控机制提供了一种系统方法。
