CYP24A1 expression analysis in uterine leiomyoma regarding MED12 mutation profile.

Uterine leiomyoma (ULM) is the most common gynecological tumor. Recent studies have revealed the role of hypovitaminosis D as a major risk factor in the disease development. CYP24A, a mitochondrial enzyme that catalyzes the degradation of 1,25(OH)2D3, is reported to be over-expressed in several human cancers. In this study, we aimed to investigate the expression level of CYP24A1 in leiomyoma samples compared with the adjacent tissues regarding the MED12 mutation profile. In the present study, 61 ULMs and adjacent tissue samples were collected from 51 women undergoing hysterectomy and myomectomy. The samples were Sanger sequenced for MED12 mutation, and the expression level of CYP24A1 was evaluated by quantitative real-time polymerase chain reaction (qRT-PCR). The results demonstrated that CYP24A1 gene was ectopically expressed in 18% of uterine leiomyoma tissues, although this expression was independent of the MED12 mutation profile. The findings of the present study support current evidence that dysregulation of vitamin D signaling and metabolic pathways may be involved in at least some subtypes of ULMs.
