Mammary tumor inhibition and lung adenoma induction by isonicotinic acid hydrazide
Science (New York, N.Y.)
|June 3, 1966
Abstract:
The occurrence of manomary adenocarcinonmas in C3H mice is largely inhibited by prolonged admninistration of 0.1 percent isonicotinic acid hydrazide in drinking water. At the same time that this compound produtced the inhibitory action, it also increased the incidence of pulmonary adenomas.
Insights
Long-term administration of isonicotinic acid hydrazide inhibited mammary tumors in mice. However, this treatment also led to a higher incidence of lung tumors in the same animal model.
Area of Science:
- Oncology
- Pharmacology
- Toxicology
Background:
- Mammary adenocarcinomas are a significant health concern.
- Understanding factors influencing tumor development is crucial for prevention and treatment strategies.
Purpose of the Study:
- To investigate the effect of isonicotinic acid hydrazide on mammary adenocarcinoma development in C3H mice.
- To assess potential side effects of isonicotinic acid hydrazide, specifically its impact on pulmonary adenoma incidence.
Main Methods:
- Prolonged administration of 0.1% isonicotinic acid hydrazide in drinking water to C3H mice.
- Observation and quantification of mammary adenocarcinoma and pulmonary adenoma occurrences.
Main Results:
- A significant inhibition in the occurrence of mammary adenocarcinomas was observed.
- A concurrent increase in the incidence of pulmonary adenomas was noted in the treated group.
Conclusions:
- Isonicotinic acid hydrazide exhibits chemopreventive properties against mammary tumors in this model.
- The compound may possess dual effects, necessitating further investigation into its mechanisms and potential risks.
