Knock down and overexpress AMIGO2 in dopamine neurons; measure a transcriptome-wide state shift (bulk RNA-seq) 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
a transcriptome-wide state shift (bulk RNA-seq)
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 a transcriptome-wide state shift (bulk RNA-seq) 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 AMIGO2 in iPSC-derived midbrain dopamine neurons (FOXA2+, LMX1A+, TH+); n = 3 differentiations; readouts: a transcriptome-wide state shift (bulk RNA-seq); 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 2308: AMIGO2 in dopamine neurons, braak

power
full sample +0.43 (p 0.074, n 18), 95% CI -0.04 to +0.75. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.38 (p 0.118, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.36 (p 0.142, n 18). could be the mix.
skeptic
leave-one-out range +0.35 to +0.58, sign flips 0; without severely affected donors +0.43 (p 0.074, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for AMIGO2 in dopamine neurons.

case closed: nothing better to follow up.
