Exosomal and non-exosomal miRNA expression levels in patients with HCV-related cirrhosis and liver cancer.

Patients with HCV-related cirrhosis are at risk for liver cancer development. For these patients miRNAs may serve as preclinical markers, which expression levels are deregulated in cancer and which are stable to the damaging factors partly through complex formation with proteins or packaging into exosomes. In this research we have tried to identify what miRNA fraction in plasma - exosomal or not packed into exosomes (non-exosomal) - is stronger associated with primary liver cancer.
