Figure 5. Expression of Stat3-up-regulated genes in COPD from smokers.
Expression of Stat3 up-regulated genes was measured by quantitative Real-Time PCR and normalized by GAPDH mRNA expression. Numbers in each column represent average ΔCt. Average fold changes were determined by 2(ΔΔCt), in which ΔΔCT= ΔCt(normal human samples) − ΔCt(COPD from smokers). Numbers on the bottom represent average fold changes compared to the normal human samples. Normal human samples were set up as one. Nor: normal samples. COPD: COPD samples from smokers.
