Knock down and overexpress KBTBD6 in dopamine neurons; measure proteasome activity and the load of ubiquitinated protein and survival of TH-positive neurons and phospho-α-synuclein (pS129) inclusions after seeding with α-synuclein fibrils.
- Cell type
- dopamine neurons
- Direction
- Both arms: public data does not say which way helps.
- Molecular readout
- proteasome activity and the load of ubiquitinated protein
- Functional readout
- survival of TH-positive neurons and phospho-α-synuclein (pS129) inclusions after seeding with α-synuclein fibrils
- Rule-out
- If neither arm moves proteasome activity by 20% or more against non-targeting and empty-vector controls, across three independent differentiations, the hypothesis is wrong.
- Lab request
- CRISPRi knockdown and lentiviral overexpression of KBTBD6 in iPSC-derived midbrain dopamine neurons (FOXA2+, LMX1A+, TH+); n = 3 differentiations; readouts: proteasome activity and the load of ubiquitinated protein; survival of TH-positive neurons and phospho-α-synuclein (pS129) inclusions after seeding with α-synuclein fibrils. Controls: non-targeting guide, empty vector. About 8 to 10 weeks, most of it differentiation.

Swarm cases
receipt 14788: KBTBD6 in dopamine neurons, braak
- power
- full sample +0.11 (p 0.677, n 18), 95% CI -0.38 to +0.55. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: +0.07 (p 0.774, n 18). does not hold up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.05 (p 0.854, n 18). could be the mix.
- skeptic
- leave-one-out range -0.00 to +0.27, sign flips 1; without severely affected donors +0.11 (p 0.677, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for KBTBD6 in dopamine neurons.
case closed: nothing better to follow up.
