Knock down and overexpress ZFYVE16 in oligodendrocytes; measure phospho-ERK and phospho-AKT response to GDNF 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
- phospho-ERK and phospho-AKT response to GDNF
- Functional readout
- α-synuclein uptake and myelin basic protein output under oxidative stress
- Rule-out
- If neither arm moves phospho-ERK 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 ZFYVE16 in iPSC-derived oligodendrocytes; n = 3 differentiations; readouts: phospho-ERK and phospho-AKT response to GDNF; 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 10233: ZFYVE16 in dopamine neurons, braak
- power
- full sample -0.14 (p 0.567, n 18), 95% CI -0.57 to +0.35. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: -0.14 (p 0.567, n 18). does not hold up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.02 (p 0.949, n 18). could be the mix.
- skeptic
- leave-one-out range -0.30 to -0.06, sign flips 0; without severely affected donors -0.14 (p 0.567, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for ZFYVE16 in dopamine neurons.
case closed: nothing better to follow up.

- composition
- oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: +0.18 (p 0.471, n 18). could be the mix.
