ROR1 and neoplasm: Consistent with the data analysis in TCGA, our qPCR experiment found significantly lower expression in CHOL tissues than in the matching non-cancerous tissues (P < 0.001, Figure D).The predictive value of ROR1-AS1 expression had a high accuracy for estimating tumor and normal outcomes, as shown by an area under the receiver operating characteristic (ROC) of 0.922–1.000 (Fig. 1C).
