    Article Snippet: The OC2 overexpression plasmid was obtained by cloning the full-length OC2 cDNA ( {"type":"entrez-nucleotide","attrs":{"text":"NM_004852","term_id":"1519245947","term_text":"NM_004852"}} NM_004852 ) into the pLenti-C-Myc-DDK-IRES-Puro (Origene).

    Techniques: ChIP-sequencing

    (a) Multiplex IF staining with anti-OC2 and anti-AR antibodies in 6 cases of high-grade PC. Heatmap and dendrogram of nuclear staining intensities of AR and OC2, using the Euclidean distance and complete linkage method in an unsupervised cluster analysis, identifies two cell populations: AR high/OC2 low and AR low/OC2 high. Scatter plot of individual nuclei separated by intensity levels of AR and OC2. Cluster 1 (C1, green) represents high AR/low OC2 cells (N=1,109) and cluster 2 (C2, purple) represents low AR/high OC2 cells (N=199). Boxplots of intensity levels of nuclear AR and OC2 in C1 (left) or C2 (right). The boxes show the 25th-75th percentile range and the center line is the median. Whiskers show 1.5 times the IQR from the 25th or 75th percentile values. Left boxplot: P=2.1×10−191, right boxplot: P=2.3×10−66, Wilcoxon two-tailed rank-sum test.

    (a) NE activation score in mCRPC tumors with high (N=65) and low (N=65) OC2 expression (top and bottom quartiles) from the DISC cohort. The boxes show the 25th-75th percentile range and the center line is the median. Whiskers show 1.5 times the IQR from the 25th or 75th percentile values. Data points beyond the whiskers are displayed using dots. Wilcoxon two-tailed rank-sum test, P=4.6×10−5.
