Abstract:
Intraperitoneal treatments with D-glucosamine, an inhibitor of the glycosylation of the viral envelope, decreased the growth rate of tumors induced in quails or in chicks by Rous sarcoma virus and increased the survival of mice inoculated with human influenza virus.
Insights
D-glucosamine, a viral envelope glycosylation inhibitor, slowed tumor growth in birds infected with Rous sarcoma virus. It also improved survival rates in mice infected with human influenza virus.
Area of Science:
- Virology
- Oncology
- Biochemistry
Background:
- Viral envelope glycosylation is crucial for virus replication and pathogenesis.
- Tumorigenesis by oncogenic viruses like Rous sarcoma virus (RSV) involves complex cellular and viral mechanisms.
- Influenza virus infections pose a significant global health burden.
Purpose of the Study:
- To investigate the antiviral and antitumor effects of D-glucosamine.
- To determine if inhibiting viral envelope glycosylation impacts tumor growth and viral survival.
Main Methods:
- Intraperitoneal administration of D-glucosamine to birds with RSV-induced tumors.
- Intraperitoneal administration of D-glucosamine to mice inoculated with human influenza virus.
Main Results:
- D-glucosamine treatment significantly decreased the growth rate of Rous sarcoma virus-induced tumors in quails and chicks.
- D-glucosamine administration increased the survival rate of mice infected with human influenza virus.
Conclusions:
- D-glucosamine exhibits potent antiviral and antitumor properties.
- Inhibition of viral envelope glycosylation is a promising therapeutic strategy against viral infections and virus-induced tumors.
