Figure 4. Stable expression of miR-20a inhibits TGF-β-induced growth inhibition and apoptosis.
A. Beas2B and HPL1A cells stably expressing miR-20a and parental and control vector cells were treated with 5 ng/ml TGF-β for 5 days. Cell numbers from 5th day count were plotted. *P < 0.05, vs. TGF-β untreated cells; #P < 0.05, vs. TGF-β treated cells in parental and vector groups. B. Cells in “Figure 4A” were treated with 5 ng/ml TGF-β for 40 h and then harvested. Apoptotic cells were analyzed by FACS. *P < 0.05, vs. TGF-β untreated cells; #P < 0.05, vs. TGF-β treated cells in Par and Vec groups.
