Transposons in Embryo Space – TRACER maps in EMAGE
Posted by chris.armit@igmm.ed.ac.uk, on 9 February 2017
A recent publication in Developmental Biology by (Armit et al., 2017) describes how the TRACER dataset can be spatially compared with in situ hybridisation gene expression profiles.
- The TRACER dataset of transposon-associated regulatory sensors (Chen et al., 2013) utilises Sleeping Beauty lacZ transposons that have been randomly integrated into the mouse genome
- Hundreds of insertions have been mapped to specific genomic positions, and the corresponding regulatory potential is documented through lacZ imaging of E11.5 wholemount mouse embryos
- Through spatial mapping of the lacZ expression patterns, the EMAGE gene expression database enables co-localisation and co-expression of regulatory elements to be explored computationally
- Spatial mapping additionally enables rapid identification of cis-regulatory elements that are expressed in a region of interest in the mouse embryo
