Using total RNA prepared from our second panel of 26 matched specimens, we confirmed that ESR1, SOX18, CCL5, and PCDH10 but not CALCRL are differentially expressed in uterine leiomyomas or that levels of their expression vary by menstrual phase (Supplemental Figs. 2 and 4). This evidence concerns the gene CCL5 and Uterine leiomyoma.
