SNP-STARR-seq in SW620

Systematic analysis of functional genetic and epigenetic variants in colorectal cancer

Targeted SNP-STARR-seq in human SW620 cells used 120-bp genomic fragments centered on candidate noncoding SNPs, with synthesized reference and alternative alleles cloned into the hORI-STARR-seq reporter. Allele-specific enhancer activity was quantified from normalized RNA/DNA EAS 36 hours after transfection.

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; reference versus alternative allele reporter oligos

The 120-bp synthetic genomic fragments were cloned into the hORI-STARR-seq plasmid. Three biological replicates and three technical PCR replicates were performed per cell line; enhancer activity score (EAS) was calculated from DESeq2-normalized RNA and DNA counts as (RNA + 1)/DNA.

Quality control

The authors aligned reads to a custom oligonucleotide library with Bowtie2 2.5.2, normalized input DNA and output RNA counts with DESeq2 1.40.0, assessed replicate reproducibility by hierarchical clustering, and selected allele-differential results using two-sided t tests with adjusted P < 0.05. Packaging QC retained 3759/3759 rows from the Table S3 SW620 worksheet after requiring a valid rsID, distinct A/C/G/T alleles, finite effect and enhancer-score values, finite probabilities in [0,1], and p_adjusted < 0.05; no rows were removed.

Curation notes

Table S3 is a significant-result table rather than the complete 30,790-SNP count matrix; this worksheet contains the reported SW620 hits. SW620 is the metastatic cell line derived from the same patient as SW480, making this a metastasis-context experiment.
