Cancer exosome ‘micro factories’ aid in cancer progression

“Exosomes derived from cells and blood serum of patients with breast cancer, have been shown to initiate tumor growth in non-tumor-forming cells when Dicer and other proteins associated with the development of miRNAs are present,” said Raghu Kalluri, M.D., Ph.D., chair of the department of cancer biology at MD Anderson. “These findings offer opportunities for the development of exosomes-based biomarkers and shed insight into the mechanisms of how cancer spreads.” Exosomes are small vesicles consisting of DNA, RNA and proteins enclosed in a membranes made up of two lipid layers. They perform specialized functions such as coagulation, intercellular signaling and cell “waste management.” They are shed into bodily fluids forming a source of disease-specific nucleic acids and proteins. Increasingly, exosomes are studied for their potential as both indicators of disease, and as a prospective new treatment approach. …
