Hypothesis
Can a transgenic mouse expressing the R122H human cationic trypsinogen serve as a model for pancreatitis?
Conclusion
The R122H transgenic mouse did not develop spontaneous pancreatitis, but showed slightly more severe pancreatitis when induced repeatedly.
Supporting Evidence
- The transgene was detected at the genomic level and in pancreatic mRNA.
- R122H mice showed elevated pancreatic lipase levels.
- There was no spontaneous development of pancreatitis within 18 months.
- After induction of pancreatitis, lipase and amylase levels were higher in R122H mice compared to controls.
- Repeated treatment with cerulein resulted in slightly more severe pancreatitis in R122H animals.
Takeaway
Scientists created a special mouse that has a gene linked to pancreatitis, but it didn't get sick on its own; when they made it sick on purpose, it was a little worse than normal mice.
Methodology
Transgenic mice were created and tested for pancreatitis by inducing it with cerulein injections and measuring enzyme levels.
Limitations
The transgenic mice did not develop spontaneous pancreatitis, limiting their use as a model for the disease.
Participant Demographics
Transgenic mice and control BalbC mice were used in the study.
