Abstract

Extracellular vesicles (EVs) secreted by tumors are abundant in plasma, but their potential for interrogating the molecular features of tumors through multi-omic profiling remains widely unexplored. Genomic and transcriptomic profiling of circulating EV-DNA and EV-RNA isolated from a range of in-vitro and in-vivo models of metastatic prostate cancer (mPC) revealed a high contribution of tumor material to EV-loaded DNA/RNA. Findings were validated in a cohort of longitudinal plasma samples collected from mPC patients during androgen receptor signaling inhibitor (ARSI) therapy. EV-DNA genomic features recapitulated matched-patient biopsies and associated with clinical progression. We developed a novel approach to enable the transcriptomic profiling of EV-RNA (RExCuE). We report how the transcriptomic profile in mPC EV-RNA is enriched for tumor-associated transcripts when compared to same patient blood RNA and healthy individuals EV-RNA, and reflect early on-therapy tumor adaptation changes. Altogether, we show that EV profiling enables longitudinal transcriptomic and genomic profiling of mPC in liquid biopsy.
