Knock down and overexpress EPHA6 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; existing compounds already reach the inhibition arm.
- 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 EPHA6 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 13855: EPHA6 in dopamine neurons, braak
- power
- full sample +0.49 (p 0.039, n 18), 95% CI +0.03 to +0.78. the interval excludes zero: something may be there, smaller than a half can see.
- confounder
- adjusted for sex: +0.48 (p 0.043, n 18). holds up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.48 (p 0.043, n 18). not the mix.
- skeptic
- leave-one-out range +0.42 to +0.63, sign flips 0; without severely affected donors +0.49 (p 0.039, n 18). robust.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for EPHA6 in dopamine neurons.
case closed: nothing better to follow up.
