Inhibition of HCV NS3 protease by RNA aptamers in cells.

abstract：:Module identification is a frequently used approach for mining local structures with more significance in global networks. Recently, a wide variety of bilayer networks are emerging to characterize the more complex biological processes. In the light of special topological properties of bilayer networks and the accompan...
