foxo4 p53 p53 - FOXO4-DRI human trials FOXO4-p53 crosstalk Unraveling the Complex Dance: The FOXO4-p53 Axis in Cellular Health and Aging

FOXO4-DRI The intricate molecular machinery governing cellular life is a constant subject of scientific exploration. Among the key players in this complex interplay are the human transcription factors FOXO4 and p53. Their interaction, often referred to as the FOXO4-p53 axis, holds significant implications for cellular health, aging, and the development of diseases like cancer. Understanding this FOXO4 and p53 relationship is crucial for developing novel therapeutic strategies.FOXO4 - an overview

At its core, p53 is a renowned tumor suppressor, vital for protecting cells against tumorigenesis by halting the cell cycle and initiating DNA repair mechanisms when faced with cellular stresses. FOXO4, on the other hand, is a transcription regulator that plays a role in apoptosis, particularly in senescent cells, by interacting with p53作者：B Bourgeois·2025·被引用次数：10—We provide a detailed characterization of the interaction ofp53withFOXO4andFOXO4-DRI which is the basis for development ofp53inhibitors.. This interaction is not merely coincidental; FOXO4 and p53 can physically interact in cells, forming a complex that influences cellular fate.

The FOXO4-p53 axis is particularly implicated in the process of cellular senescence, a state where cells stop dividing.作者：R Mandal·2021—The previous study has demonstrated that the physical interaction betweenFOXO4 and p53represses apoptosis of senescent cells by upregulating the transcription ... While senescence can prevent uncontrolled proliferation, the accumulation of senescent cells contributes to aging and age-related diseases.Regulation of cellular senescence via the FOXO4‐p53 axis Emerging research highlights how FOXO4 protects senescent cell viabilityBiophysical characterization of the interaction between .... It achieves this by interacting with p53 and, in some contexts, sequestering it, thereby preventing p53 from inducing apoptosis.FOXO4 interacts with p53 TAD and CRD and inhibits its ... This means that the FOXO4 and p53 interaction can sustain cell survival, even in cells that are otherwise marked for elimination.

This understanding has paved the way for the development of senolytic therapies, aimed at selectively eliminating senescent cells. A notable example is FOXO4-DRI, which is recognized as a senolytic peptide that targets p53. FOXO4-DRI acts as a cell-permeable peptide antagonist that blocks the interaction of FOXO4 and p53. By disrupting this FOXO4-p53 crosstalk, FOXO4-DRI can induce apoptosis in senescent cells, offering a potential avenue for rejuvenation. Indeed, studies have shown that FOXO4-DRI mitigates senescence by inhibiting the FOXO4-P53 interaction, promoting p53 phosphorylation, and inducing apoptosisFOXO4-DRI regulates endothelial cell senescence via the .... This mechanism underpins the therapeutic potential of interfering with the FOXO4-p53 axis.

The relationship between FOXO4 and p53 is multifaceted and extends beyond senescence作者：R Zhang·2022·被引用次数：1—Forkhead box protein O4 (FOXO4) plays a pivotal role in cellular senescence, by binding to and inactivating p53, thereby leading to cellular .... It is known that FOXO4 and p53 regulate aging, and their deregulation has been linked to several diseases, including cancer作者：J Kim·2022·被引用次数：18—Forkhead box O4 (FOXO4) and p53 arehuman transcription factorsknown to promote senescence by interacting with each other and activating p21 transcription.. The complex nature of their interaction is a significant area of ongoing research. For instance, the FOXO4-TP53 interaction is being extensively studied using molecular modeling to design senolytic peptides for the elimination of senescent cancer cells. The precise mechanisms by which this interaction influences cellular processes are being elucidated, with researchers investigating how FOXO4 can inhibit p53's transactivation function.

The FOXO4-p53 axis is not only relevant in cancer but also in other physiological contexts. For example, research suggests that FOXO4-DRI can alleviate testosterone secretion insufficiency and improve testicular function, indicating broader systemic effects mediated by this interaction.2025年7月1日—We recently identified theFOXO4 - p53 axisas pivotal in maintaining the viability of senescent cells, and that senescent cells can be targeted ...

In essence, the FOXO4-p53 axis represents a critical regulatory hub within the cell.2025年7月1日—We recently identified theFOXO4 - p53 axisas pivotal in maintaining the viability of senescent cells, and that senescent cells can be targeted ... While p53 is a cornerstone of genomic stability, FOXO4 modulates its activity, particularly in the context of senescence and apoptosis. The ability of molecules like FOXO4-DRI to specifically disrupt this interaction opens exciting possibilities for therapeutic interventions targeting age-related diseases and cancer, highlighting the profound impact of understanding these fundamental biological pathways.
