Knock down and overexpress LRRC4C 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 LRRC4C 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 1018: LRRC4C in dopamine neurons, braak
- power
- full sample +0.32 (p 0.201, n 18), 95% CI -0.18 to +0.68. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: +0.31 (p 0.214, n 18). does not hold up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.37 (p 0.135, n 18). could be the mix.
- skeptic
- leave-one-out range +0.22 to +0.51, sign flips 0; without severely affected donors +0.32 (p 0.201, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for LRRC4C in dopamine neurons.
case closed: nothing better to follow up.
receipt 1017: LRRC4C in oligodendrocytes, braak
- power
- full sample +0.02 (p 0.935, n 18), 95% CI -0.45 to +0.48. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: -0.03 (p 0.922, n 18). does not hold up.
- composition
- oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: -0.01 (p 0.976, n 18). could be the mix.
- skeptic
- leave-one-out range -0.10 to +0.12, sign flips 7; without severely affected donors +0.02 (p 0.935, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for LRRC4C in oligodendrocytes.
