Methyl-STARR-seq in SW480

Systematic analysis of functional genetic and epigenetic variants in colorectal cancer

Targeted Methyl-STARR-seq in human SW480 cells used 120-bp genomic fragments centered on H3K27ac summits or CRC DMR CpGs cloned into pmSTARRseq1. M.SssI-treated methylated and mock-treated unmethylated plasmid libraries were compared after transfection, with RNA collected 36 hours later.

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; M.SssI-treated methylated versus mock-treated unmethylated plasmid libraries

The methylation library used 120-bp synthetic fragments centered on H3K27ac peak summits or CRC differential-methylation CpGs. Half of the pmSTARRseq1 plasmid library was methylated in vitro with M.SssI and the other half was mock treated; bisulfite conversion was assessed, and EAS was calculated from DESeq2-normalized RNA/DNA counts as (RNA + 1)/DNA across three biological and three technical PCR replicates.

Column dictionary · 15 definitions
element_id
Normalized source element label with the leading '>' removed.
source_element
Source identifier prefix: hg19 for a generic enhancer-centered window, cg... for an Illumina CpG probe, or hg19pc for a human control.
methyl_cpg_locus
Original Table S4 locus label, including its leading '>' prefix.
chromosome
Human chromosome for the tested window in hg19.
window_start_hg19
Start coordinate of the reported genomic window in hg19.
window_end_hg19
End coordinate of the reported genomic window in hg19.
window_length_bp
Reported length of the tested window in base pairs, normally 120.
cpg_offset_0based
Reported zero-based offset of the tested CpG within the window.
log2_methylated_unmethylated
Source-reported log2 ratio of methylated versus unmethylated enhancer activity score.
p_value
Raw two-sided t-test P value for the methylation effect.
p_adjusted
Multiple-testing-adjusted P value from the source table.
unmethylated_enhancer_score
Enhancer activity score for the mock-treated/unmethylated plasmid library.
methylated_enhancer_score
Enhancer activity score for the M.SssI-treated/methylated plasmid library.

source_table
Supplementary workbook and worksheet of origin.

Quality control

The authors assessed bisulfite conversion, used three biological replicates and three technical PCR replicates, normalized RNA/DNA counts with DESeq2, and selected methylation-sensitive results using two-sided t tests with adjusted P < 0.05. Packaging QC retained 3588/3588 rows from the Table S4 SW480 worksheet after requiring a human hg19/CpG-probe locus with a valid window, finite effect and probabilities in [0,1], p_adjusted < 0.05, and nonnegative enhancer scores where supplied; no rows were removed.

Curation notes

Table S4 is a significant-result table rather than the complete >134,000-CpG library count matrix. SW480 is a primary colorectal cancer cell line and is paired with metastatic SW620 in this study; source element labels include generic hg19 windows and CpG-probe-labelled windows.
