CUL4B and neoplasm: As shown in Table 2, miR-101-3p and CUL4B expressions are highly correlated with PCA TNM staging, Gleason scores of tumor size, and preoperative PSA; in addition, based on the median value of the relative miR-101-3p and CUL4B expression levels, PCA patients were divided into two groups: low expression group and high expression group.
