Abstract:
For investigating the effect of Jumonji domain-containing protein-3 (JMJD3) on the behavior of lung cancer cell line, A549 proliferation was measured with EDU staining and flow cytometer after JMJD3 expression plasmid and pcDNA3. 1 transfection at 48h. The migration ability of A549 was tested at the same time. The expression of p21 mRNA was measured with RT-PCR. The results showed that JMJD3 transfection increased the EDU positive cells ratio (JMJD3: 40.75% +/- 2.07%, control: 20.97% +/- 1.5%, P < 0.001). G1 phase cell ration also increased after JMJD3 transfection (JMJD3:47. 80% +/- 1.85%, control: 54.60% +/- 0.95%, P = 0.005). The mRNA expression of p21 decreased in JMJD3 group (JMJD3: 35. 89% +/- 3.71%, control: 91.78% +/- 3.74%, P < 0.001). The distances of migration were (0.47 +/- 0.27) cm and (0.96 +/- 0.40) cm after 24h and 48h with JMJD3 tranfection, compared to (0.57 +/- 0.22)cm and (1.08 +/- 0.33)cm in control, respectively (P > 0.05). JMJD3 promoted the proliferation of A549 and decreased the G1 cell numbers, decreased the p21 mRNA, but had no effect on A549 migration.
