Knock down and overexpress DLG1 in oligodendrocytes; measure evoked dopamine release and dopamine transporter uptake 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
- evoked dopamine release and dopamine transporter uptake
- Functional readout
- α-synuclein uptake and myelin basic protein output under oxidative stress
- Rule-out
- If neither arm moves evoked dopamine release 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 DLG1 in iPSC-derived oligodendrocytes; n = 3 differentiations; readouts: evoked dopamine release and dopamine transporter uptake; 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 2909: DLG1 in dopamine neurons, braak
- power
- full sample +0.13 (p 0.597, n 18), 95% CI -0.36 to +0.57. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: +0.14 (p 0.579, n 18). does not hold up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.24 (p 0.332, n 18). could be the mix.
- skeptic
- leave-one-out range +0.02 to +0.26, sign flips 0; without severely affected donors +0.13 (p 0.597, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for DLG1 in dopamine neurons.
case closed: nothing better to follow up.
receipt 2908: DLG1 in oligodendrocytes, braak
- power
- full sample +0.36 (p 0.148, n 18), 95% CI -0.13 to +0.71. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: +0.37 (p 0.135, n 18). does not hold up.
- composition
- oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: +0.26 (p 0.302, n 18). could be the mix.
- skeptic
- leave-one-out range +0.27 to +0.51, sign flips 0; without severely affected donors +0.36 (p 0.148, n 18). fragile.
- cell type
- no other cell group does better.
