Figure 6From: Efficient inhibition of HIV-1 replication by an artificial polycistronic miRNA constructExpression levels of mature miRNAs derived from miR-ACB transcripts compared to individual antiviral miRNA transcripts. RNA was isolated from MT-4 cell lines expressing miRNAs and analyzed by northern blot using 19 nt complementary oligonucleotide probes. U6 RNA served as a loading control.Back to article page
