While comparable immunohistochemistry data on the prognostic role of ROCK1 expression in prostate cancer are lacking, analysis of mRNA expression data from 85 prostate cancers from Taylor et al. [19] (raw data via GEO GSE21032) confirmed ROCK1 up-regulation in 21 recurrent (average mRNA expression level: 8.3) as compared to disease-free cancers (average 8.1, p=0.0263). This evidence concerns the gene ROCK1 and cancer.
