Tetracycline-responsive Twister riboswitch screen

High-throughput identification of synthetic riboswitches by barcode-free amplicon-sequencing in human cells

Nine synthetic Twister sublibraries (2N3N, 3N2N, 3N3N and CG/noCG variants; 18,432 constructs total) were screened in HEK-293H cells. Self-barcoding cDNA amplicon counts were measured after 3 h untreated, 12.5 µM, 25 µM, or 50 µM tetracycline stimulation, with eight biological replicates per condition.

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

Untreated, 12.5 µM, 25 µM, or 50 µM tetracycline for 3 h

Transient episomal CMV-eGFP reporter with nine Twister ribozyme communication-module libraries in the eGFP 3′ UTR. Sequence-defined construct identities were quantified by cDNA amplicon sequencing on an Illumina NextSeq 500; published edgeR log2 fold changes and FDRs are joined to the corresponding motif keys from source-data sheet 5b.

Quality control

The authors evaluated library abundance, replicate concordance, GC dependence, and low-abundance behavior. For this package, missing construct counts were treated as zero; a construct was retained only when it had total count > 0, was detected in at least 2 of 8 replicates in every condition, and had finite published log2FC and FDR for all three tetracycline contrasts. All 18,432 input constructs passed these filters.

Curation notes

The nine sublibraries are represented as the pattern_name column so they remain analyzable in one table. The raw GEO archive also contains library-QC samples outside this experiment’s 32 screen samples; those inputs are preserved in raw_data but not mixed into the table. The library is fully synthetic, so no reference genome or genomic interval applies.
