[The inhibitory effect of bcl-2 antisense oligodeoxynucleotide/RNA on the growth of cervical carcinoma in vitro]
1Department of Obstetrics and Gynecology, General Hospital, Tianjin Medical University, Tianjin 300052, China.
Objective:
To study the therapeutic effect of bcl-2 antisense oligodeoxynucleotide (ODN)/RNA human cervical carcinoma in vitro.
Methods:
To transfect bcl-2 antisense ODN/RNA into Hela cells with antisense technology and observe the growth and apoptotic modulation of Hela cells.
Results:
The expression of bcl-2 protein and mRNA was higher in Hela cells; the bcl-2 specific antisense ODN significantly decreased bcl-2 protein expression and inhibit the growth of Hela cells. The strongest inhibitory effect was at 24 hours after transfection, the optimal concentration of antisense ODN was 10 micromol/L. The results indicated that the inhibitory effect of bcl-2 antisense ODN on cell growth and survival rate is dose dependent; the recombinant retroviral vector pDOR-AB can transfer antisense bcl-2 gene into the genome of Hela cells, bcl-2 protein and mRNA expressions were significantly decreased after transfected, it demonstrated bcl-2 antisense RNA can significantly inhibit the growth of Hela cells and induce their apoptosis.
Conclusion:
The results demonstrate the feasibility of bcl-2 gene as a target for antisense gene therapy of human cervical carcinoma and provide the theoretical foundation and experimental evidence for further study in vivo.
Insights
Bcl-2 antisense oligodeoxynucleotide (ODN) effectively inhibits human cervical carcinoma cell growth and induces apoptosis in vitro. This study supports bcl-2 gene therapy for cervical cancer.
Area of Science:
- Molecular Biology
- Cancer Research
- Gene Therapy
Context:
- Human cervical carcinoma exhibits elevated bcl-2 protein and mRNA expression.
- Antisense technology offers a potential therapeutic strategy for targeting specific gene expression.
Purpose:
- To investigate the therapeutic efficacy of bcl-2 antisense oligodeoxynucleotide (ODN)/RNA in human cervical carcinoma cells in vitro.
- To evaluate the impact of bcl-2 antisense ODN/RNA on Hela cell growth and apoptosis.
Summary:
- Transfection of Hela cells with bcl-2 antisense ODN/RNA significantly reduced bcl-2 protein and mRNA levels.
- Antisense ODN demonstrated a dose-dependent inhibition of Hela cell growth and survival, with optimal effects observed at 10 micromol/L after 24 hours.
- Recombinant retroviral vector pDOR-AB successfully integrated the antisense bcl-2 gene into Hela cells, leading to decreased bcl-2 expression and induced apoptosis.
Impact:
- The findings establish the feasibility of targeting the bcl-2 gene for antisense gene therapy in human cervical carcinoma.
- Provides a theoretical basis and experimental evidence for future in vivo studies and development of novel cancer treatments.
