Knock down and overexpress RARG in a dopamine neuron, astrocyte and microglia tri-culture; measure phospho-ERK and phospho-AKT response to GDNF and dopamine neuron survival after α-synuclein fibril challenge.
- Cell type
- a dopamine neuron, astrocyte and microglia tri-culture
- Direction
- Both arms: public data does not say which way helps; existing compounds already reach the inhibition arm.
- Molecular readout
- phospho-ERK and phospho-AKT response to GDNF
- Functional readout
- dopamine neuron survival after α-synuclein fibril challenge
- 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 RARG in a tri-culture of iPSC dopamine neurons, astrocytes and microglia; n = 3 differentiations; readouts: phospho-ERK and phospho-AKT response to GDNF; dopamine neuron survival after α-synuclein fibril challenge. Controls: non-targeting guide, empty vector. About 8 to 10 weeks, most of it differentiation.

Swarm cases
receipt 2154: RARG in dopamine neurons, braak
- power
- full sample -0.52 (p 0.027, n 18), 95% CI -0.79 to -0.07. the interval excludes zero: something may be there, smaller than a half can see.
- confounder
- adjusted for sex: -0.52 (p 0.027, n 18). holds up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.71 (p 9.1e-4, n 18). not the mix.
- skeptic
- leave-one-out range -0.63 to -0.46, sign flips 0; without severely affected donors -0.52 (p 0.027, n 18). robust.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for RARG in dopamine neurons.
case closed: nothing better to follow up.
