Circulating Tumor Extracellular Vesicles to Monitor Metastatic Prostate Cancer Genomics and Transcriptomic Evolution

Highlights:
  • EV profiling enables longitudinal interrogation of metastatic PC using liquid biopsy
  • EV-DNA genomic profiling recapitulates tumor features and associates with progression
  • RExCuE allows mRNA analysis in circulating EVs for liquid biopsies transcriptomic profiling
  • EV-RNA indicates early tumor adaptation changes during therapy in a non-invasive manner
Summary:
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 in vitro and in vivo models of metastatic prostate cancer (mPC) reveal a high contribution of tumor material to EV-loaded DNA/RNA, validating the findings in two cohorts of longitudinal plasma samples collected from patients during androgen receptor signaling inhibitor (ARSI) or taxane-based therapy. EV-DNA genomic features recapitulate matched-patient biopsies and circulating tumor DNA (ctDNA) and associate with clinical progression. We develop a novel approach to enable transcriptomic profiling of EV-RNA (RExCuE). We report how the transcriptome of circulating EVs is enriched for tumor-associated transcripts, captures certain patient and tumor features, and reflects on-therapy tumor adaptation changes. Altogether, we show that EV profiling enables longitudinal transcriptomic and genomic profiling of mPC in liquid biopsy.
