Knock down and overexpress STRADA in oligodendrocytes; measure a transcriptome-wide state shift (bulk RNA-seq) and α-synuclein uptake and myelin basic protein output under oxidative stress.

Cell type
oligodendrocytes
Direction
Both arms: public data does not say which way helps.
Molecular readout
a transcriptome-wide state shift (bulk RNA-seq)
Functional readout
α-synuclein uptake and myelin basic protein output under oxidative stress
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 STRADA in iPSC-derived oligodendrocytes; n = 3 differentiations; readouts: a transcriptome-wide state shift (bulk RNA-seq); α-synuclein uptake and myelin basic protein output under oxidative stress. Controls: non-targeting guide, empty vector. About 8 to 10 weeks, most of it differentiation.

Swarm cases

receipt 1338: STRADA in dopamine neurons, braak

power
full sample -0.20 (p 0.429, n 18), 95% CI -0.61 to +0.30. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.17 (p 0.493, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.25 (p 0.323, n 18). could be the mix.
skeptic
leave-one-out range -0.35 to -0.10, sign flips 0; without severely affected donors -0.20 (p 0.429, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for STRADA in dopamine neurons.

case closed: nothing better to follow up.

receipt 1337: STRADA in oligodendrocytes, braak

power
full sample -0.06 (p 0.820, n 18), 95% CI -0.51 to +0.42. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.08 (p 0.767, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: -0.02 (p 0.928, n 18). could be the mix.
skeptic
leave-one-out range -0.21 to +0.08, sign flips 3; without severely affected donors -0.06 (p 0.820, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for STRADA in oligodendrocytes.
