Background:
Increase in expression of eIF4E (Eukaryotic translation initiation factor 4E) protein is mediated by oncogenic proteins of Human Papilloma Virus (HPV). Increased expression of eIF4E plays an important role in HPV induced carcinogenesis. Ribavirin and Indinavir are known inhibitors of eIF4E activity.
Methods:
The effect of the drugs on HeLa cells was assessed by in vitro assays including cell viability using MTT and Neutral red assay, apoptotic potential using Caspase-3, Caspase-8 and Caspase-9 activity assays and MMP-2 and MMP-9 secretion by determination of Gelatinase activity. The in vivo effect of Ribavirin treatment on tumor volume was assessed in human xenograft in immunocompromised C57BL/6 mice.
Results:
In vitro analyses indicate that Ribavirin and Indinavir reduce viability of HeLa cells, induce apoptosis and decrease secretion of MMPs. Treatment with Ribavirin at a dose of 50mg/kg and 100mg/kg daily led to significant decrease in tumor volume in vivo.
Conclusion:
The study thus provides evidence that Ribavirin and Indinavir can be explored as therapy against HPV-18 induced cervical cancer.
Insights
Ribavirin and Indinavir show promise in fighting HPV-18 cervical cancer by inhibiting eIF4E. These drugs reduced cancer cell viability and tumor growth in preclinical studies.
Area of Science:
- Oncology
- Virology
- Molecular Biology
Background:
- Human Papilloma Virus (HPV) oncogenic proteins increase Eukaryotic translation initiation factor 4E (eIF4E) expression, contributing to HPV-induced carcinogenesis.
- eIF4E plays a critical role in the development of HPV-related cancers.
- Ribavirin and Indinavir are known inhibitors of eIF4E activity.
Purpose of the Study:
- To investigate the therapeutic potential of Ribavirin and Indinavir against HPV-18 induced cervical cancer.
- To assess the effects of Ribavirin and Indinavir on cancer cell viability, apoptosis, and matrix metalloproteinase (MMP) secretion.
- To evaluate the in vivo efficacy of Ribavirin in reducing tumor volume.
Main Methods:
- In vitro assays on HeLa cells: MTT and Neutral red assays for cell viability, Caspase activity assays for apoptosis, and Gelatinase activity assays for MMP-2 and MMP-9 secretion.
- In vivo study using human xenografts in immunocompromised C57BL/6 mice to assess Ribavirin's effect on tumor volume.
Main Results:
- Ribavirin and Indinavir demonstrated significant reduction in HeLa cell viability in vitro.
- Both drugs induced apoptosis and decreased MMP secretion in vitro.
- Daily treatment with Ribavirin (50mg/kg and 100mg/kg) resulted in a significant decrease in tumor volume in vivo.
Conclusions:
- Ribavirin and Indinavir exhibit anti-cancer properties against HPV-18.
- These drugs can be considered as potential therapeutic agents for HPV-18 induced cervical cancer.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
