Piperine effectively targets cancer cells and senescent cells, offering a dual approach to cancer treatment by inducing senostatic effects and eliminating cancer cells. This study positions piperine as a primary cancer therapeutic, not an adjunct therapy.
Area of Science:
- Oncology
- Gerontology
- Cell Biology
Background:
- Cancer is linked to aging and senescent cells, which impede cancer treatments via SASP secretion.
- Targeting both cancer and senescent cells is crucial for effective cancer therapy.
- Piperine is investigated for its potential as a senostatic and anticancer agent.
Purpose of the Study:
- To investigate the selective effects of piperine on cancer and senescent cells.
- To evaluate piperine's potential as a senostatic agent and anticancer drug.
Main Methods:
- Cytotoxicity and proliferation assays (LDH, WST).
- Western blot analysis for p16INK4a, p21, MAPKs, and mTOR.
- Assessment of senescence markers (SA-β-Gal, MMP, ROS) and SASP secretion.
Main Results:
- Piperine exhibited high cytotoxicity in cancer cell lines.
- Piperine promoted proliferation in senescent cells, similar to nicotinamide.
- Piperine modulated intracellular pathways, reversed senescence phenotypes, and altered SASP in senescent cells.
Conclusions:
- Piperine demonstrates selective effects on cancer and senescent cells.
- Piperine acts as a senostatic agent and anticancer drug.
- Piperine is proposed as a standalone cancer treatment for simultaneous senostasis and cancer cell removal.
