Figure 3. Expression of components of adenosine metabolism and signaling.

Figure 3

Transcript levels of various enzymes in adenosine metabolism, and adenosine receptors were quantified in lung RNA extracts from patients using quantitative RT-PCR. Shown are levels of (A) CD73, (B) ADA, (C) AK, (D) ENT1, (E) Adenosine receptors. Results are presented as mean percentage of 18sRNA transcripts ± SEM. *p≤0.05 versus Stage 0 COPD. #p≤0.05 versus Mild IPF. n = 4 (Stage 0 COPD), n = 10 (Mild IPF), n = 8 (Stage 4 COPD and Severe IPF).
