BMI1 and ovarian neoplasm: To further investigate the interaction between miR-200b and its target genes, we performed a comprehensive analysis of miR‐200b and BMI-1 and VEGF-A levels in clinical ovarian tumor tissues that were collected and analyzed using matched mRNA and miRNA expression profiles, revealing a significant inverse correlation between miR-200b expression and both BMI-1 and VEGF-A expression (Fig. 4c).
