Exosome-Derived Analytes Mirror Cancer Cells: The trafficking of biological analytes (e.g., proteins, metabolites, nucleotides) across the cell membrane is part of any normal cell homeostasis. In a vesicular transport mechanism, the analytes are transported across the cell membrane via exosomes, which are small extracellular vesicles. In pathological states such as cancer, the circulating exosome-derived analytes may mirror the altered state (e.g., over- or under expressed key proteins and microRNAs) of the cell of origin, and therefore, can be of substantial diagnostic value. Over the past decade, a number of studies have implicated exosomes in major tumor-related pathways such as hypoxia-driven epithelial-to-mesenchymal transition, cancer stemness, angiogenesis, malignant formation, metastasis and drug resistance However, the findings have been inconsistent and variable.










Exosome are and other extracellular vesicles (EVs) are membrane enclosed vesicles that are secreted by all cells, circulated in the blood and are readily accessible in most body fluids. The cargo of these vesicles includes RNA, DNA, proteins, metabolites and lipids that are reflective of the cell of origin making exosomes appealing for biomarker development. EVs are categorized into exosomes, microvesicles, apoptotic bodies and Golgi vesicles. Exosomes are formed when multivesicular endosomes (MVE) fuse to the plasma membrane. Once secreted into the extracellular environment exosomes can function as mediators of intercellular signaling, can modulate the stroma and endothelial tissue, and can regulate inflammatory and immune responses. Cancer cells release more exosomes than normal cells and exosomes secreted from tumor cells can promote tumor progression, survival, invasion and angiogenesis. The analysis of exosomes isolated from blood or other body fluids could provide insight on cancer cell biology and predictive biomarkers for early detection, progression and metastasis.

Additional Information

Agency Name: National Institutes of Health
Description: This Funding Opportunity Announcement (FOA) encourages research projects that focus on innovative research in the isolation and characterization of exosomes and their cargo for discovery of predictive biomarkers for risk assessment, detection, diagnosis and prognosis of early cancer. This FOA will promote rigor and reproducibility research in both the isolation of exosomes as well as the computational analysis of the cargo carried in these vesicles.
