Hypothesis
The down regulation of miR-146a could be due to decreased activity of NFkB in STHdhQ111/HdhQ111 cells.
Conclusion
The study concludes that decreased expression of miR-146a is mediated through decreased expression and activity of RelA/NFkB, and increased expression of p53 in Huntington's disease models could be due to decreased expression of miR-125b and miR-150.
Supporting Evidence
- Decreased miR-146a expression in STHdhQ111/HdhQ111 cells is linked to reduced NFkB activity.
- Increased p53 levels in Huntington's disease models are associated with decreased miR-125b and miR-150 expressions.
- Exogenous expression of RelA/NFkB can restore miR-146a levels in Huntington's disease cell models.
Takeaway
In Huntington's disease, certain tiny molecules called microRNAs that help control genes are not working properly, which can lead to problems in brain cells.
Methodology
The study used luciferase reporter assays, real-time PCR, and western blot analysis to investigate the expression levels of miR-146a and its regulators.
Potential Biases
Potential bias may arise from the reliance on specific cell models that may not capture all aspects of the disease.
Limitations
The study primarily focuses on cell models and may not fully represent the complexity of Huntington's disease in humans.
