Hydrocortisone/CORT108297 STARR-seq in A549 cells

Glucocorticoids unmask silent non-coding genetic risk variants for common diseases

The same human STARR-seq PGx-eQTL plasmid library was transfected into the A549 lung cancer cell line to test context-dependent enhancer activity. Cells were exposed for 9 h to vehicle, 100 nM hydrocortisone, or 100 nM CORT108297; the table contains the 94 published SNP–gene loci with GR-dependent STARR-seq activity calls.

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

Vehicle (0.1% DMSO + 0.1% ethanol), 100 nM hydrocortisone + 0.1% DMSO, or 100 nM CORT108297 + 0.1% ethanol for 9 h

Human STARR-seq-ORI plasmid (Addgene #99296) carried PCR-amplified PGx-eQTL peak fragments extended by approximately ±500 bp, with an FKBP5 enhancer positive control. Active inserts self-transcribed from the reporter, were enriched by RT-PCR, and were quantified by paired-end sequencing; the same library was tested under vehicle, hydrocortisone, and CORT108297 conditions.

Quality control

The authors reported greater than 90% mapping across samples and replicate r² ≥ 0.9. Adapter and universal plasmid sequence were removed, reads were aligned to GRCh37/hg19 with BWA-MEM, MAPQ ≥30 reads were retained, allele/locus counts were called with bcftools mpileup and HTSeq, and indels, multiallelic variants, and variants with counts <20 were removed. For this package, only the 94 of 134 Supplementary Data 2 rows marked Yes for GR-dependent STARR-seq activity were retained.

Curation notes

The source workbook provides qualitative STARR-seq activity/direction strings rather than numeric count or log2 fold-change values; those strings are retained verbatim in the table and the parsed direction is only assigned when the row's rsID is explicitly named. Variant positions were recovered by matching REF/ALT and cloned interval against the deposited VCF when unique; 11 retained rows have no unique match and 8 have multiple candidate matches, which are left blank or listed in the candidate column. A549 is represented by Cellosaurus accession CVCL:0023.
