Overexpression of the lung cancer-prognostic miR-146b microRNAs has a minimal and negative effect on the malignant phenotype of A549 lung cancer cells

Biological effects of overexpression of miR-146b microRNAs in the A549 human lung cancer cell-line was studied. A549 cells were engineered to express the precursor RNA (pre-miR-146b) that generates the miR-146b microRNAs. Control cells were engineered using the same gene expression plasmid (pLemiR, Open Biosystems) but without the pre-miR-146b insert. The Trans-Lentiviral GIPZ packaging system (Open Biosystems) was used to generate stable transfectant populations of the engineered cells.
