Knock down and overexpress NR4A2 in a dopamine neuron, astrocyte and microglia tri-culture; measure proteasome activity and the load of ubiquitinated protein and dopamine neuron survival after α-synuclein fibril challenge.
- Cell type
- a dopamine neuron, astrocyte and microglia tri-culture
- Direction
- Both arms: public data does not say which way helps.
- Molecular readout
- proteasome activity and the load of ubiquitinated protein
- Functional readout
- dopamine neuron survival after α-synuclein fibril challenge
- 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 NR4A2 in a tri-culture of iPSC dopamine neurons, astrocytes and microglia; n = 3 differentiations; readouts: proteasome activity and the load of ubiquitinated protein; dopamine neuron survival after α-synuclein fibril challenge. Controls: non-targeting guide, empty vector. About 8 to 10 weeks, most of it differentiation.

Swarm cases
receipt 0220: NR4A2 in dopamine neurons, braak
- power
- full sample -0.43 (p 0.077, n 18), 95% CI -0.75 to +0.05. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: -0.53 (p 0.022, n 18). holds up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.50 (p 0.033, n 18). not the mix.
- skeptic
- leave-one-out range -0.52 to -0.35, sign flips 0; without severely affected donors -0.43 (p 0.077, n 18). robust.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for NR4A2 in dopamine neurons.
case closed: nothing better to follow up.
