Knock down and overexpress SLC18B1 in astrocytes; measure a transcriptome-wide state shift (bulk RNA-seq) and α-synuclein uptake and degradation, and dopamine neuron survival in co-culture.
- Cell type
- astrocytes
- 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 degradation, and dopamine neuron survival in co-culture
- 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 SLC18B1 in iPSC-derived midbrain astrocytes; n = 3 differentiations; readouts: a transcriptome-wide state shift (bulk RNA-seq); α-synuclein uptake and degradation, and dopamine neuron survival in co-culture. Controls: non-targeting guide, empty vector. About 8 to 10 weeks, most of it differentiation.

Swarm cases
receipt 1545: SLC18B1 in dopamine neurons, braak
- power
- full sample +0.13 (p 0.615, n 18), 95% CI -0.36 to +0.56. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: +0.13 (p 0.597, n 18). does not hold up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.23 (p 0.360, n 18). could be the mix.
- skeptic
- leave-one-out range -0.01 to +0.21, sign flips 2; without severely affected donors +0.13 (p 0.615, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for SLC18B1 in dopamine neurons.
case closed: nothing better to follow up.
receipt 1544: SLC18B1 in astrocytes, braak
- power
- full sample +0.33 (p 0.182, n 18), 95% CI -0.16 to +0.69. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: +0.33 (p 0.182, n 18). does not hold up.
- composition
- astrocytes share of nuclei vs axis -0.21 (p 0.413); controlling for it: +0.25 (p 0.315, n 18). could be the mix.
- skeptic
- leave-one-out range +0.23 to +0.46, sign flips 0; without severely affected donors +0.33 (p 0.182, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for SLC18B1 in astrocytes.
