Experiment / E325Z6TK13' UTR / RNA Stability MPRA (MPRAu)

Guanine-responsive HDV-ribozyme and hammerhead riboswitch screen

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

A pooled guanine-responsive library tested 4,096 hepatitis-delta-virus ribozyme constructs and 16,384 hammerhead ribozyme constructs in the CMV-eGFP 3′ UTR of transiently transfected HEK-293H cells. Self-barcoding cDNA amplicon counts were measured after 3 h untreated, 30 µM, 100 µM, or 300 µM guanine stimulation, with eight biological replicates per condition.

Perturbation & assay details

Untreated, 30 µM, 100 µM, or 300 µM guanine for 3 h

Transient episomal CMV-eGFP reporter with two pooled synthetic ribozyme libraries in the eGFP 3′ UTR: lib1 (HDV ribozyme) and lib2 (hammerhead ribozyme). Sequence-defined construct identities were quantified by cDNA amplicon sequencing on an Illumina NextSeq 500; published edgeR log2 fold changes and FDRs are joined from source-data sheets 3c and 4c.

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 guanine contrasts. Of 20,480 input constructs, 20,478 passed; one construct failed the replicate-detection filter and one lacked a complete published statistic.

Curation notes

Both libraries were intentionally kept in one pooled experiment table and are distinguishable by pattern_name. Missing raw count rows were represented as zero before QC. The library is fully synthetic, so no reference genome or genomic interval applies.
