Hypothesis
Do major histocompatibility complex (MHC) genes influence the composition of urinary volatiles in mice?
Conclusion
The study found no significant qualitative differences in urinary volatiles between mice with and without functional MHC class I molecules.
Supporting Evidence
- Mice with different MHC genes showed no qualitative differences in urine volatiles.
- Significant quantitative differences were observed between various mouse strains.
- Individual variability in urine scent was noted even within the same strain.
Takeaway
Mice have different smells based on their genes, but the genes that help their immune system don't seem to change their urine smell much.
Methodology
Urine samples from different mouse strains were collected and analyzed using gas chromatography/mass spectrometry.
Potential Biases
Potential bias due to environmental factors affecting the volatile profiles.
Limitations
The study only analyzed a fraction of the total number of volatiles present in the urine.
Participant Demographics
C57BL/6J mice and various mutant strains.
