Knock down and overexpress POLR2E 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.
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 POLR2E 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 12643: POLR2E in dopamine neurons, braak

power
full sample -0.02 (p 0.928, n 18), 95% CI -0.48 to +0.45. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.04 (p 0.881, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.06 (p 0.807, n 18). could be the mix.
skeptic
leave-one-out range -0.13 to +0.12, sign flips 5; without severely affected donors -0.02 (p 0.928, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for POLR2E in dopamine neurons.

case closed: nothing better to follow up.
