Hypothesis
The study analyzes the expression of stress kinases in the cortex and neurons of MPS IIIB mice to understand their role in disease pathogenesis.
Conclusion
The study found increased activation of ERK and JNK in the early stages of MPS IIIB, suggesting their involvement in the disease's pathogenesis.
Supporting Evidence
- ERK1/2 activation was significantly higher in the cortex of 1–2-month-old MPS IIIB mice compared to wild-type.
- SAPK/JNK was also activated in the cortex of affected animals.
- p38MAPK was found to be lower in MPS IIIB mice compared to wild-type.
- HS levels were significantly higher in neurons from MPS IIIB mice compared to controls.
Takeaway
Mice with a specific disease showed changes in brain proteins that might help us understand how the disease affects their brains.
Methodology
The study used Western blotting to analyze the activation of stress kinases in the cortex and cultured neurons from MPS IIIB mice.
Limitations
The study does not exclude the possibility of MAPK activation occurring outside the cortical area.
Participant Demographics
MPS IIIB mice and wild-type littermates of various ages.
