Figure 2. Hypoxic regulation of CXCR4 and VLA4 mRNA expression. A, B) Levels of CXCR4 and VLA4 mRNA expression were assessed in RPMI- 8226 cells using quantitative PCR after 72 h under 1 % O2 culture, respectively. RPMI-8226-pLKO.1 and RPMI-8226-plenti-III-off-miR210 were used as control of anti-HIF-1α, and anti-miR-210, respectively. Mean values ± standard deviation for 3 independent experiments are shown. **P<0.01. Abbreviation: N.S (not significant).
