SOSHI-seq Library 1: TRα1/TRβ1 response to T3

SOSHI-seq: a high-throughput screening assay to test the functionality of putative response elements for nuclear hormone receptors

A pool of approximately 1,000 mouse genomic TRα1 binding-site fragments was cloned into the transcribed region of an episomal pSTARRseq-ori reporter and tested in HEK293 cells. Two independent batches (RUN25 and RUN66) were assayed with TRα1/RXRα or TRβ1/RXRα expression, with and without 10 nM T3.

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

10 nM T3 (3,3′,5-triiodo-L-thyronine) for approximately 24 h versus no T3

SOSHI-seq is a hormone-response adaptation of STARR-seq. Chemically synthesized 200-mer oligos contained approximately 158 nt of mouse genomic sequence plus common amplification flanks and were cloned into the transcribed portion of pSTARRseq-ori (Addgene #71509). HEK293 cells were co-transfected with the library, human RXRα, and either TRα1 or TRβ1 expression plasmid; T3 was added 6 h after transfection. Reporter RNA was reverse-transcribed, amplified, sequenced as single-end MiSeq reads, and counted after unique mapping to mouse GRCm38/mm10.

Quality control

The paper retained fragments with at least 10 reads in every one of the eight reporter-RNA count files (two batches × TRα1/TRβ1 ± T3), yielding 800 of 991 deposited Library 1 fragments. Reads that did not map uniquely were binned (<20% non-unique reads). The paper used DESeq2 with T3 treatment and batch as factors and reported source adjusted-p-value/regulation fields; only the read-depth-passing fragments are present in table.csv.

Curation notes

The HEK293 biosample is human (CVCL:0045), whereas every tested insert and genomic coordinate is mouse. RUN25 corresponds to the GEO repeat-1 samples and RUN66 to repeat-2; the source workbook labels these result blocks Exp.2 and Exp.1, respectively, so this table uses the GEO run names. The article describes this as a relative hormone-response ranking rather than an absolute enhancer activity measurement. The workbook contains a side-by-side FIMO table; only its fragment-keyed orientation/position/p-value fields were joined, while the unkeyed auxiliary field was not carried into the processed table.
