Abstract:
Senescence, a crucial yet paradoxical phenomenon in cellular biology, acts as a barrier against cancer progression while simultaneously promoting aging and age-related pathologies. This duality underlines the importance of precise monitoring of senescence response, especially with regard to the proposed use of drugs selectively removing senescent cells. In particular, little is known about the role of senescence in neurons and in neurodegenerative diseases. Our study investigates the senescence response in neuroblastoma SH-SY5Y cells and human neural progenitor ReNcell VM cells exposed to doxorubicin, a chemotherapeutic agent known to induce DNA damage and subsequent senescence. Through a comprehensive analysis employing the most robust senescence markers, we characterized the senescence-associated patterns in these neural cell lines including cellular morphological changes, SA-beta-gal, γH2A.X, p21Waf1/Cip1 and p16Ink4a. Our findings indicate that ReNcell VM cells exhibit greater senescence-associated response at lower doxorubicin concentrations compared to SH-SY5Y cells. Additionally, we observed cell-type-specific differences in timing and levels of the expression of key cell cycle regulators during senescence. Our results emphasize the necessity of cell-type-specific strategies in senescence research with regard to implications as well as limitations for translation into aging and neurodegenerative disorders.
Insights
Cellular senescence, a key process in aging and cancer, was studied in neural cells. Human neural progenitor cells showed a stronger senescence response to doxorubicin than neuroblastoma cells, highlighting cell-type-specific differences.
Area of Science:
- Cellular Biology
- Neuroscience
- Aging Research
Background:
- Cellular senescence is a critical biological process with dual roles in cancer prevention and aging.
- Understanding senescence in neurons is vital for neurodegenerative disease research.
- Doxorubicin is a chemotherapeutic agent known to induce DNA damage and senescence.
Purpose of the Study:
- To investigate the senescence response in two neural cell lines (SH-SY5Y and ReNcell VM) exposed to doxorubicin.
- To characterize senescence-associated patterns using established markers.
- To explore cell-type-specific differences in senescence induction and regulation.
Main Methods:
- Exposure of neuroblastoma SH-SY5Y and human neural progenitor ReNcell VM cells to doxorubicin.
- Comprehensive analysis of senescence markers: SA-beta-gal, γH2A.X, p21Waf1/Cip1, and p16Ink4a.
- Assessment of cellular morphological changes and cell cycle regulator expression.
Main Results:
- ReNcell VM cells demonstrated a more pronounced senescence response at lower doxorubicin concentrations compared to SH-SY5Y cells.
- Observed cell-type-specific variations in the timing and levels of key cell cycle regulator expression during senescence.
- Detailed characterization of senescence-associated patterns in both neural cell lines.
Conclusions:
- Neural cell senescence exhibits significant cell-type-specific differences.
- These findings underscore the need for tailored strategies in senescence research for aging and neurodegenerative disorders.
- The study provides insights into the limitations and implications of translating senescence research to clinical applications.
