Genetic intervention through a lentiviral approach and interaction detection. a GFP expression 72 h after MDA-MB-231 was infected with recombinant virus. The infection rate was estimated by observing the number of the cells expressing GFP in each view. Determination of miR-890 by qRT-PCR with U6 served as internal reference, and the CD147 protein level was detected by western blotting with β-actin (37 kDa) served as an internal reference (down). b The same experimental data appeared in HCC-70. ** P < 0.01. The tests were carried out on three biological triplicates, and data are expressed as the mean ± SD
