DKK-1 and p38 MAPK expression are correlated in prostate cancer. (a) A cDNA prostate cancer array was used to quantify DKK-1 and MAPK expression in prostate cancer. Expression levels were normalized to beta-actin. The intersecting red lines and values represent the mean expression in normal and progressive tumor stages. (b) Positive correlation of DKK-1 with each p38 MAPK isoform tested in prostate cancer cDNA samples. Correlation was calculated using Pearson's r correlation analysis and linear regression calculation
