Hypothesis
Is the disease-associated mutation in VCP a loss-of-function or a gain-of-function mutation?
Conclusion
Loss of function of VCP/TER94 is linked to neurodegeneration.
Supporting Evidence
- Knockdown of TER94 caused premature lethality in Drosophila.
- Alterations in brain morphology were observed in TER94 knockdown flies.
- Wild-type TER94 rescued the phenotypes caused by its knockdown, while the A229E mutant did not.
Takeaway
When a gene called TER94 is not working properly, it can cause brain and eye problems in fruit flies, which helps us understand a similar issue in humans.
Methodology
The study used Drosophila models with RNA interference to knock down the TER94 gene and assessed the resulting phenotypes.
