Epigenomic changes play an important role during the progression of melanoma

Human DNA contains genetic information that makes our cells functional entities within a larger whole. The stream of information from DNA to function happens in the form of proteins that anchor themselves to various locations in the DNA and transcribe genetic information into functional cell parts. This process is strictly regulated and is thus very sensitive to change by external factors…

Cancer exosome ‘micro factories’ aid in cancer progression — ScienceDaily

“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…
