Abstract:
Cellular senescence is a program of irreversible cell cycle arrest that cells undergo in response to a variety of intrinsic and extrinsic stimuli including progressive shortening of telomeres, changes in telomeric structure or other forms of genotoxic and non-genotoxic stress. The role of nuclear factor-κB in cellular senescence is controversial, as it has been associated with both proliferation and tumour progression, and also with growth arrest and ageing. This research perspective focuses on the evidence for a functional relationship between NF-κB and senescence, and how disruption of the NF-κB pathway can lead to its bypass.
Insights
Nuclear factor-kappa B (NF-κB) plays a complex role in cellular senescence, a state of irreversible cell cycle arrest. This research explores the functional link between NF-κB and senescence, and how pathway disruption can bypass this crucial cellular process.
Area of Science:
- Molecular Biology
- Cell Biology
- Genetics
Background:
- Cellular senescence is a fundamental biological process involving irreversible cell cycle arrest.
- Senescence is triggered by various intrinsic and extrinsic stressors, including telomere attrition and genotoxic damage.
- The role of nuclear factor-kappa B (NF-κB) in senescence is debated, with associations to both proliferation and growth arrest.
Purpose of the Study:
- To investigate the functional relationship between NF-κB signaling and cellular senescence.
- To explore how dysregulation of the NF-κB pathway impacts the induction or bypass of senescence.
Main Methods:
- This research perspective synthesizes existing evidence from various studies.
- Analysis of literature focusing on NF-κB signaling pathways and senescence markers.
- Review of experimental data linking NF-κB activity to cell cycle arrest and aging phenotypes.
Main Results:
- Evidence suggests a complex, dual role for NF-κB in cellular senescence.
- NF-κB activation can be both a driver and a suppressor of senescence depending on context.
- Disruption of NF-κB signaling pathways is implicated in the bypass of senescence.
Conclusions:
- A functional interplay exists between NF-κB and the establishment of cellular senescence.
- Understanding this relationship is critical for deciphering senescence roles in aging and cancer.
- Targeting NF-κB pathways may offer strategies to modulate senescence in disease contexts.
