Objective:
To investigate the mechanism of delaying the senescence of human diploid fibroblast (2BS) by total flavone of Ginkgo biloba (FG).
Methods:
The drug sera of FG was used to treat the 2BS. The population doublings of 2BS cells were observed, the mRNA expression of P16 gene was determined by fluorescence real-time quantitative PCR.
Results:
FG significantly extended the population doublings of 2BS cells, and decreased the expression of P16 mRNA.
Conclusion:
FG can delay the senescence of cells by inhibiting the P16 gene expression.
Insights

Background:
- Cellular senescence is a key factor in aging.
- Human diploid fibroblasts (2BS) are a model for studying senescence.
- Ginkgo biloba extracts have shown potential anti-aging properties.
Purpose of the Study:
- To investigate the mechanism by which total flavone of Ginkgo biloba (FG) delays senescence in 2BS cells.
- To determine the effect of FG on P16 gene expression.
Main Methods:
- Treatment of 2BS cells with FG.
- Observation of cell population doublings.
- Quantification of P16 mRNA expression using fluorescence real-time quantitative PCR.
Main Results:
- FG significantly extended the population doublings of 2BS cells.
- FG treatment led to a decrease in P16 mRNA expression.
Conclusions:
- Total flavone of Ginkgo biloba (FG) effectively delays cellular senescence.
- FG exerts its anti-senescence effect by inhibiting the expression of the P16 gene.
