Changes in serum microRNAs have been reported for many tumor types. However, how well global changes in tumor microRNA expression are reflected in circulating microRNAs is less understood. Using a mouse genetic model of HCC, we found that that serum microRNA pro¬files reflect both changes in the tumor tissues and systemic response to tumor burden. The serum-specific alteration included microRNAs linked to immune response, liver injury and other systemic responses to the tumor burden. Interestingly, most of the changes in both liver and serum are reversed upon inhibition of the driving oncogene. This pre-clinical proof-of-concept demonstrates that circulating microRNAs are suitable candidates for tumor detection as well as monitoring disease progression and treatment response. |
