Background:
α-Pinene is one of the most widely found terpenoids in nature. Substantial evidence shows that α-pinene has cancer prevention properties. In this study, the PC-3 cell line was used to establish subcutaneous xenograft tumors in nude mice.
Methods:
Cytotoxicity was measured with the MTT assay, and apoptosis and cell cycle analyses were conducted using flow cytometry in vitro. The PC-3 cell line was used to establish subcutaneous xenograft tumors in nude mice.
Results:
We found that treatment with α-pinene significantly inhibited human prostate cancer cell growth and induced apoptosis and cell cycle arrest in the cell line-based model. Furthermore, tumor progression was inhibited more in mice treated with α-pinene than in control mice. We detected less Ki67 and proliferation cell nuclear antigen in paraffin sections from xenograft tumor specimens taken from α-pinene-treated mice than in those from the control group. Meanwhile, α-pinene treatment induced apoptosis in xenograft tumors as determined by the TUNEL assay.
Conclusions:
These data strongly suggest that α-pinene inhibits prostate cancer growth in a xenograft model and may be an effective therapeutic agent for prostate cancer treatment.
Insights
Alpha-pinene, a natural terpenoid, effectively inhibits prostate cancer cell growth and progression. This study demonstrates its potential as a therapeutic agent for prostate cancer treatment.
Area of Science:
- Natural product chemistry
- Cancer biology
- Pharmacology
Background:
- Alpha-pinene is a prevalent natural terpenoid with documented cancer-preventive properties.
- Prostate cancer remains a significant global health concern, necessitating novel therapeutic strategies.
Purpose of the Study:
- To investigate the efficacy of alpha-pinene in inhibiting prostate cancer growth.
- To explore the mechanisms underlying alpha-pinene's anti-cancer effects in vitro and in vivo.
Main Methods:
- Cytotoxicity assessed via MTT assay.
- Apoptosis and cell cycle analysis performed using flow cytometry.
- Subcutaneous xenograft tumors established in nude mice using the PC-3 cell line.
Main Results:
- Alpha-pinene significantly suppressed human prostate cancer cell proliferation and induced apoptosis and cell cycle arrest in vitro.
- In vivo, alpha-pinene treatment markedly inhibited tumor progression in xenograft models.
- Reduced expression of proliferation markers (Ki67, PCNA) and increased apoptosis (TUNEL assay) observed in treated tumors.
Conclusions:
- Alpha-pinene demonstrates significant anti-prostate cancer activity in a preclinical xenograft model.
- These findings suggest alpha-pinene holds promise as a potential therapeutic agent for prostate cancer.
