Knock down and overexpress ST6GAL2 in oligodendrocytes; measure oxygen consumption rate and ATP output 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
- oxygen consumption rate and ATP output
- Functional readout
- α-synuclein uptake and myelin basic protein output under oxidative stress
- Rule-out
- If neither arm moves oxygen consumption rate 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 ST6GAL2 in iPSC-derived oligodendrocytes; n = 3 differentiations; readouts: oxygen consumption rate and ATP output; 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 14129: ST6GAL2 in dopamine neurons, braak
- power
- full sample +0.34 (p 0.173, n 18), 95% CI -0.16 to +0.69. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: +0.36 (p 0.140, n 18). does not hold up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.53 (p 0.024, n 18). not the mix.
- skeptic
- leave-one-out range +0.26 to +0.51, sign flips 0; without severely affected donors +0.34 (p 0.173, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for ST6GAL2 in dopamine neurons.
case closed: nothing better to follow up.
receipt 14128: ST6GAL2 in oligodendrocytes, braak
- power
- full sample -0.09 (p 0.715, n 18), 95% CI -0.54 to +0.39. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: -0.13 (p 0.609, n 18). does not hold up.
- composition
- oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: -0.14 (p 0.573, n 18). could be the mix.
- skeptic
- leave-one-out range -0.19 to +0.02, sign flips 3; without severely affected donors -0.09 (p 0.715, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for ST6GAL2 in oligodendrocytes.
case closed: nothing better to follow up.
