Expression of HHIP target genes associated with ECM (A) or cell growth (B) were measured in human COPD and control lung tissues by RT-PCR. Relative expression values were calculated as described in Materials and Methods and represent means± standard errors for COPD (n=15) and Controls (n=18). **p<0.01 and *p<0.05. n.s., non-significant.
