Here we describe identification of 1089 gene-centric common insertion sites (gCIS) from
transposon-based screens in 8 mouse models of BC. Some gCIS are driver-specific, others
driver non-specific, and still others associated with tumor histology. Processes affected by
driver-specific and histology-specific mutations include well-known cancer pathways. Driver
non-specific gCIS target the Mediator complex, Ca++ signaling, Cyclin D turnover, RNA …
