Hypothesis
C-peptide replacement can prevent hippocampal apoptosis and neuronal loss in type 1 diabetic BB/W rats.
Conclusion
C-peptide replacement in type 1 diabetic BB/W rats protects against hippocampal apoptosis and neuronal loss.
Supporting Evidence
- C-peptide replacement prevented DNA laddering in the hippocampus of diabetic rats.
- Diabetic rats showed a significant loss of CA1 neurons after 8 months, which was reduced with C-peptide.
- C-peptide administration normalized IGF expression levels in the hippocampus.
- Apoptosis was demonstrated in diabetic rats but not in those treated with C-peptide.
Takeaway
This study found that giving C-peptide to diabetic rats helps protect their brain cells from dying.
Methodology
The study involved diabetic BB/W rats treated with C-peptide and assessed for neuronal apoptosis and IGF expression.
Limitations
The study was conducted on animal models, which may not fully represent human conditions.
Participant Demographics
Male BB/W rats, both diabetic and non-diabetic.
