Expanding on Exosomes and Ectosomes in Cancer.

The article discusses research which investigated capability of cancer exosomes to perform microRNA biogenesis and contribute to tumorigenesis, conducted by S. A. Melo and colleagues, published in a 2014 issue of "Cancer Cell" journal. Topics explored include the conversion of pre-microRNA to mature microRNA by these exosomes, the active microRNA formation observed in breast cancer cell lines-derived exosomes, and the presence of these exosomes in serum specimens.
