Abstract
Exosomes are lipid bilayer extracellular vesicles (EVs) of 50-150nm in size, which contain nucleic acids (mRNA, ncRNAs and DNA), proteins and lipids. They are secreted by all cells and circulate in all body fluids. Exosomes are key mediators of several processes in cancer that mediate tumor progression and metastasis. These nano-vesicles, when secreted from cancer cells, are enriched in non-coding RNAs (e.g. microRNAs) complexed with the RNA-Induced Silencing Complex (RISC), that mediate an efficient and rapid silencing of mRNAs at the recipient cell, reprogramming their transcriptome. MicroRNAs in circulation encapsulated in exosomes are protected from degradation by a lipid bilayer and might serve as potential non-invasive diagnostic and screening tools to detect early stage cancer, to facilitate treatment options and possible help in curative surgical therapy decisions. Additionally, engineered exosomes can be used as therapy vehicles for targeted delivery of RNAi molecules, escaping the immune system detection.
Keywords: Exosomes, Extracellular vesicles, microRNAs, microRNA biogenesis, Non-coding RNAs.

New insights on Pediatric Tumors and Associated Cancer Predisposition Syndromes
Because of the broad spectrum of children cancer susceptibility, the diagnosis of cancer risk syndromes in children is rarely used in direct cancer treatment. The field of pediatric cancer genetics and genomics will only continue to expand as a result of increasing use of genetic testing tools. It's possible that ...read more
