NCL is Upregulated in Aggressive Forms of PCa Violin plots displaying nucleolin (NCL) mRNA expression levels in patient tumor samples stratified by clinical characteristics from (A) TCGA provisional database, queried through cBioPortal (Gleason 6–7 n = 291; Gleason 8–10 n = 206; Pearson: r = 0.134; Spearman: rs = 0.127), and (B) Sun et al. (non-recurrent n = 39; biochemical recurrence n = 38), (C) Yu et al., and Chandran et al. queried through NCBI GEO (normal tissue n = 81; localized prostate cancer (PCa) n = 65; metastatic PCa n = 25 sample locations from four patients). A Student’s t-test was used for group analyses. ** p < 0.01, **** p < 0.0001.
