A MYC and RAS co-activation signature in localized prostate cancer drives bone metastasis and castration resistance.

ABSTRACT: Understanding the intricacies of lethal prostate cancer poses specific challenges due to difficulties in accurate modeling of metastasis in vivo. Here we show that NPK ^EYFP mice (for Nkx3.1 ^CreERT2/+ ; Pten ^flox/flox ; Kras ^LSL-G12D/+ ; R26R-CAG-^LSL-EYFP/+) develop prostate cancer with a high penetrance of metastasis to bone, thereby enabling detection and tracking of bone metastasis in vivo and ex vivo. Transcriptomic and whole-exome analyses of bone metastasis from these mice revealed distinct molecular profiles conserved between human and mouse and specific patterns of subclonal branching from the primary tumor. Integrating bulk and single-cell transcriptomic data from mouse and human datasets with
