The mRNA expression levels of SATB2 in all nine of the MED12m-positive uterine fibroids and 75% (9 of 12 samples) of the MED12m-negative uterine fibroids were more than twice those in the myometrium (Fig. 6c and Supplementary Table S10 online), while the mRNA expression levels of NRG1 in all the MED12m-positive uterine fibroids and 67% (8 of 12 samples) of the MED12m-negative uterine fibroids were more than twice those in the myometrium, (Fig. 6d and Supplementary Table S10 online). This evidence concerns the gene NRG1 and uterine corpus leiomyoma.
