Hypothesis
The study investigates the relationship between cachexia and blood glucose levels in mice bearing different types of adenocarcinomas.
Conclusion
The MAC16 adenocarcinoma causes a decrease in blood glucose levels as weight loss increases, while the MAC13 adenocarcinoma does not affect blood glucose levels.
Supporting Evidence
- Mice with the MAC16 tumor showed a progressive decrease in blood glucose levels as weight loss increased.
- Mice with the MAC13 tumor did not show any decrease in blood glucose levels.
- The study found no increased expression of IGF-I or IGF-II mRNA in the MAC16 tumor.
Takeaway
Mice with a specific type of tumor lose weight and have lower blood sugar, while mice with a similar tumor that doesn't cause weight loss have normal blood sugar.
Methodology
NMRI mice were implanted with MAC16 or MAC13 tumors, and blood glucose levels and body weight were monitored.
Limitations
The study does not determine the exact mechanism causing hypoglycaemia in the MAC16 model.
Participant Demographics
Male NMRI mice, starting weight 28 g.
