Berberine and Senescence Overview
Effects on Cellular Aging
Berberine has shown promising results in extending cellular lifespan and improving the characteristics of senescent cells. In studies involving human fetal lung diploid fibroblasts (2BS and WI38), berberine extended the replicative lifespan, improved cell morphology, and boosted rejuvenation markers associated with cellular senescence. This compound successfully reduced the rate of senescence-associated β-galactosidase (SA-β-gal)-positive cells by approximately 72% in late population doubling cells grown in a berberine-containing medium.
The action of berberine in ameliorating cellular senescence includes the down-regulation of p16 and the up-regulation of cyclin D1 and CDK4. These changes foster a cellular transition from the G1 to the S phase during early mitosis, facilitating improved cell growth and proliferation.

Berberine and Cellular Rejuvenation
Reversal of Senescence Markers
Berberine has demonstrated a remarkable ability to reverse certain markers of cellular senescence. Research shows that when senescent cells are cultivated in berberine-containing mediums, the rates of senescence-associated β-galactosidase (SA-β-gal)-positive cells in late population doubling are approximately 72% lower compared to control groups (Aging Cell). This suggests that berberine actively rescues and rejuvenates aging cells, contributing to their functional recovery and longevity.
Additionally, berberine influences several key proteins involved in cell aging. It down-regulates p16, which is known to promote senescence, while up-regulating cyclin D1 and CDK4. This modulation facilitates the transition from the G1 phase to the S phase of the cell cycle during early mitosis, promoting better cell cycle progression.
Promotion of Cell-Cycle Progression
The efficacy of berberine in promoting cell-cycle progression has been well-documented. Specifically, it facilitates the transition of human diploid fibroblasts from dormant states (G0) or initial growth phases (G1) into active phases (S/G2-M). This is critical for sustaining cellular growth and proliferation.
In studies involving human fetal lung diploid fibroblasts (2BS and WI38), berberine not only extended the replicative lifespan but also improved cell morphology and rejuvenation markers. This further highlights berberine’s potential in enhancing cellular vitality and longevity. Additionally, in experimental settings, berberine was shown to reduce doxorubicin-induced senescence, alleviating adverse effects such as weight loss and coordination issues in accelerated aging mouse models. Remarkably, it extended the median lifespan of these models by approximately 52%.
These findings illustrate that berberine acts not only as a cellular rejuvenator but also as a promising candidate in the quest for longevity and improved health outcomes in senescent cells.

Berberine and Mitochondrial Health
Impact on Mitochondrial Dysfunction
Berberine has shown promising effects on mitochondrial health, particularly in the context of aging and senescence. It suppresses gero-conversion—a process where cells transition from cell cycle arrest to senescence. This suppression occurs through the inhibition of mTOR/S6 signaling, which is essential for cell survival and growth. Berberine localizes within mitochondria, inhibits the respiratory electron chain, and activates AMPK (AMP-activated protein kinase), ultimately leading to decreased cellular aging markers and improved metabolic health.
Research indicates that berberine’s effects are notable even at low concentrations, such as 5 μM, which significantly decreases the senescent phenotype in cells undergoing premature aging. This effect arises from the attenuation of mTOR/S6 signaling and a reduction in the phosphorylation levels of ribosomal S6 protein (rpS6) (Aging-US).
The following table summarizes berberine’s impact on rpS6 phosphorylation in A549 cells:
| Treatment Time | rpS6 Phosphorylation Reduction (%) |

| 0 hours | 0% |
| 12 hours | 30% |
| 24 hours | 59% |
Regulation of Aging Signaling Pathways
Berberine plays a significant role in regulating various aging signaling pathways, including those invovled in cellular senescence. It has been shown to down-regulate the expression of p16, cyclin D1, CDK4, and RB proteins, all of which are critical regulators of the cell cycle. This regulatory action can promote cell-cycle progression, ameliorating cellular senescence (Aging Cell).
Additionally, berberine mitigates age-related cellular changes by targeting signaling pathways associated with oxidative stress and inflammation. By influencing these pathways, berberine has been linked to extending lifespan and enhancing overall cellular health.
