Knock down and overexpress CDK7 in a dopamine neuron, astrocyte and microglia tri-culture; measure PINK1–parkin mitophagy flux (mt-Keima) and phospho-ubiquitin (pS65-Ub) 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; existing compounds already reach the inhibition arm.
- Molecular readout
- PINK1–parkin mitophagy flux (mt-Keima) and phospho-ubiquitin (pS65-Ub)
- Functional readout
- dopamine neuron survival after α-synuclein fibril challenge
- Rule-out
- If neither arm moves PINK1–parkin mitophagy flux (mt-Keima) 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 CDK7 in a tri-culture of iPSC dopamine neurons, astrocytes and microglia; n = 3 differentiations; readouts: PINK1–parkin mitophagy flux (mt-Keima) and phospho-ubiquitin (pS65-Ub); 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 13480: CDK7 in dopamine neurons, braak
- power
- full sample -0.01 (p 0.976, n 18), 95% CI -0.47 to +0.46. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: -0.03 (p 0.915, n 18). does not hold up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.03 (p 0.915, n 18). could be the mix.
- skeptic
- leave-one-out range -0.14 to +0.09, sign flips 9; without severely affected donors -0.01 (p 0.976, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for CDK7 in dopamine neurons.
case closed: nothing better to follow up.
