Lentiviral MPRA in proliferating SH-SY5Y neuroblastoma cells

Integrative analyses highlight functional regulatory variants associated with neuropsychiatric diseases

The candidate variant library was tested in proliferating SH-SY5Y neuroblastoma cells using integrated lentiMPRA barcode RNA and plasmid DNA readouts.

Perturbation & assay details

Basal / proliferating SH-SY5Y culture

Lentiviral integrated MPRA using 145-bp hg19/GRCh37 reference/alternate inserts, a 10-bp filler/linker between restriction sites, 20-bp barcodes (10 barcodes per genomic instance), plasmid DNA baseline and barcode RNA readout analyzed with MPRAnalyze v1.4.0.

Quality control

The paper used barcode concordance across biological replicates, RNA/plasmid model diagnostics, replicate reproducibility and exclusion of poorly replicating or poor-quality cultures; MPRAnalyze v1.4.0 likelihood-ratio p-values were FDR-adjusted. Published daSNVs were required to have FDR < 0.05 and absolute log2 fold change > 0.05. Package-level QC additionally required both Ref and all_alt groups to be present in the GEO matrix and all count-derived metrics to be finite. No arbitrary depth cutoff was added because the released GEO aggregation does not reproduce the S5 MPRAnalyze summaries exactly.

Curation notes

GEO sample columns: SH-SY5Y.prog_1=GSM6862281; SH-SY5Y.prog_2=GSM6862282; SH-SY5Y.prog_3=GSM6862283. The paper's nomenclature calls the genome assembly hg19/hg37; this package represents it as GRCh37. S5 SHSY5Y.prog provides 1814 finite coordinate-labelled model results, of which 114 meet the published daSNV threshold; 1806 remained after requiring both allele groups and finite GEO-derived metrics. Raw GEO scores are provided as independently calculated, sample-depth-normalized log2 RNA/DNA activities and should not be interpreted as replacements for the published MPRAnalyze estimates.
