Neuro-2a neuronal cell line 3′UTR RNA-localization MPRA

The same plasmid reporter library of 150-nt native mouse 3′UTR tiles and designed motif or synthetic-sequence variants was transfected into differentiated Neuro-2a cells grown on 3-µm transwell inserts. Soma and neurite fractions were collected after transfection and profiled in three biological replicates each using UMI-based targeted reporter sequencing.

Processed tables are specific to each experiment. Column names, units, measurements, and table structure are not standardized across the database. Check this experiment’s column definitions and quality-control notes before comparing or combining data.

Perturbation & assay details

Basal / untreated after serum-starvation differentiation

CMV promoter → eGFP → 12-nt barcode → 150-nt 3′UTR test sequence → polyadenylation site; 198-nt oligos were cloned into a pcDNA3-EGFP-derived episomal reporter. Soma and neurite RNA were separated on transwell inserts and measured by targeted cDNA sequencing with 15-nt UMIs; the primary readout is edgeR log2 fold-change for neurite versus soma abundance.

Quality control

The paper’s barcode/UMI mapping and edgeR enrichment workflow was retained. For this cell-line arm, the processed table keeps only variants with a nonzero UMI count in each of the six Neuro-2a soma/neurite libraries (43,798 of 47,347 Supplementary Table S2 variants). Localization calls are derived as neurite- or soma-enriched when the corresponding published p-value is <0.05 and the log2 fold-change has the matching sign; all retained rows are marked qc_pass=true.

Curation notes

CAD and Neuro-2a were parallel cell-line arms of the same reporter-library study and are represented as separate child experiments so each record has one Cellosaurus biosample. This table retains all distinct barcoded library variants passing the count-availability filter, including the native 3′UTR tiles and designed motif/synthetic sublibraries; it does not collapse repeated sequences with different barcodes. The reference genome is recorded as mm10 because the Supplementary Table S1 mouse coordinates match the mm10/GRCm38 assembly, although the article does not print an assembly label. The original GEO file contains 642 additional barcode-only records without Supplementary Table S2 annotations; they are retained in raw_data but excluded here.
