From: Upregulation of the long non-coding RNA CASC9 as a biomarker for squamous cell carcinoma
Expression of lncRNA CASC9 in different bladder cancer tissue specimen. Muscle-invasive urothelial carcinomas without any histological signs of squamous differentiation (UC) were compared with adjacent normal control samples (N), mixed tumors consisting of muscle-invasive urothelial carcinomas displaying histological areas with squamous differentiation (MIX) and pure squamous carcinomas of the bladder (SCC). LncRNA expression measured by RT-qPCR (relative expression to geometric mean of reference genes SDHA and TBP) is displayed as a boxplot graph. P-values for difference between control (N) and tumor samples were calculated by Wilcoxon-rank-sum-Test
