Due to the similarities between granulosa cell tumors and those of mesothelial lineage, Tu et al. [72] showed that miR-126 constrains the tumorigenesis of granulosa cell tumors via directly targeting EGFL7 and suppressing the phosphatidylinositol 3-kinase/ATK (PI3K/AKT) pathway. The gene discussed is EGFL7; the disease is granulosa cell tumor.
