Global 50,332-region HDI-STARR-seq enhancer screen in mouse liver

HDI-STARR-seq: Condition-specific enhancer discovery in mouse liver in vivo

A high-complexity STARR-TYC6 library of DNase-I-released mouse liver genomic fragments was delivered to mouse liver by hydrodynamic injection. Reporter activity was measured 7 days later in four untreated males, four TCPOBOP-treated males and three untreated females, with plasmid/DNA input normalization and condition-specific enhancer classifications.

Perturbation & assay details

Vehicle control or TCPOBOP (3 mg/kg, 24 h before collection) in male mice; untreated female control group

Episomal STARR-seq plasmid delivered in vivo by hydrodynamic tail-vein injection. The STARR-TYC6 reporter uses the modified minimal mouse Albumin promoter; inserts are orientation-independent DNase-I-released genomic fragments. The source reports normalized plasmid, liver DNA and reporter-RNA reads, per-condition mean enhancer activity, replicate-level QC classification, nearest gene/TAD annotations, and mm10 liftover coordinates.

Quality control

The source pipeline aligned paired-end reads to mm9 with Bowtie2, retained uniquely aligned reads, called and merged MACS2 peaks across plasmid, DNA and RNA libraries, removed peaks represented only in RNA or overlapping ENCODE blacklisted regions, and reduced 117,122 merged peaks to 50,332 autosomal regions with more than 40 normalized plasmid reads per 10 million mapped reads. Reporter-RNA values below 20 normalized reads per 10 million were excluded from condition means; active enhancers required the threshold in at least 3 of 4 male, 3 of 4 TCPOBOP-male, or 3 of 3 female livers. Stringently inactive regions were below the threshold in all 11 livers. The packaged table retains all 50,332 source-qualified rows, including active, stringently inactive and low/inconsistent regions.

Curation notes

The global library was assembled from pooled DNase-I-released fragments and analyzed as an in vivo episomal STARR-seq assay. The source workbook has 50,332 data rows despite occasional narrative references to 50,322; this package follows the exact 50,332 qualified rows and preserves both mm9 coordinates and source mm10 liftover. The 117,122-peak starting set and the active/inactive definitions are documented in the raw supplementary workbook and GEO metadata.
