POOL1 pNoCMVMPRA1 HeLa MPRA

High-throughput functional analysis of lncRNA core promoters elucidates rules governing tissue specificity

approximately 120,000 oligo TSS/core-promoter library was assayed in HeLa cells using the no-minimal-promoter GFP reporter (pNoCMVMPRA1). RNA barcode output was normalized to matched input DNA across 4 replicate(s).

Quality control

Retained input-DNA barcodes with >=5 reads and RNA observations with >5 reads, following the released author implementation. The element inclusion set was based on HeLa DNA coverage for POOL1; each condition table additionally requires at least one condition-specific DNA-qualified barcode and one RNA-qualified barcode. Non-control elements were required to have >=3 DNA-qualified barcodes in that library-level inclusion set, while available RANDOM/SCRAMBLED controls were retained. Added pseudocount 1, CPM-normalized DNA/RNA, calculated RNA/DNA log2 activity, median-centered and quantile-normalized replicates, then collapsed barcode activities by element median. Author significance fields use Mann–Whitney tests versus RANDOM controls, Stouffer combination, and Bonferroni correction. The article prose says five or more RNA reads, but the released implementation uses a strict >5 comparison.

Curation notes

GEO count files: GSM3304508_POOL1_pNoCMVMPRA1_HeLa_rep1_COUNTS.txt.gz, GSM3304509_POOL1_pNoCMVMPRA1_HeLa_rep2_COUNTS.txt.gz, GSM3304510_POOL1_pNoCMVMPRA1_HeLa_rep3_COUNTS.txt.gz, GSM3304511_POOL1_pNoCMVMPRA1_HeLa_rep4_COUNTS.txt.gz. Raw GEO replicate order is used in activity_log2_rep columns; author tables for this condition use the corresponding non-pilot replicate labels. Rows retained: 5072; DNA-qualified barcode rows: 106290. Coordinates use hg19/FANTOM5/Gencode-era indexes; no FASTQs are included.
