Table 1

Contents of cancer exosomes.

ContentMolecular typesFunction

RNAMicroRNA (miRNA)Inducing metastasis, invasion, and transformation and formation of tumors in noncancerous cells; serving as biomarkers in cancers
Long noncoding RNA (IncRNA)Promoting tumorigenesis by facilitating angiogenesis, suppressing immune functions, and inducing metastasis
Circular RNA (circRNA)Promoting carcinoma growth and metastasis
DNADNA in exosomes (exoDNA)Being associated with abnormal DNA replication in cancer cells, and reverse transcription of cellular RNA; mediating immune response activation
ProteinTargeting/adhesion proteinsRegulating tumor proliferation, growth, metastasis, migration, angiogenesis, adhesion, immune suppression, and many other biological processes of tumor; having potential immunotherapeutic effects
Membrane transport and fusion proteins
Heat shock proteins
Enzymes
Receptor proteins
Cell type-specific markers of the originating cells
