The aim of a study by Yu et al. [70] was to investigate the relationship between four miRNAs (miR-24, miR-93, miR-126, and miR-34a), chosen based on experiments, in silico software, and the literature, and proteins related to the pituitary tumor invasion mechanism (i.e., basic fibroblast growth factor 2 (FGF2), pituitary tumor transforming gene (PTTG), CCNB1, survivin, focal adhesion kinase (FAK), and microvessel density (MVD)). This evidence concerns the gene CCNB1 and pituitary tumor.
