Long-term vitamin D treatment decreases human uterine leiomyoma size in a xenograft animal model
2019
Objective To study the effects of short- and long-term vitamin D treatment on uterine leiomyomas in vivo through cell proliferation, extracellular matrix (ECM) degradation, and apoptosis. Design Preclinical study of human leiomyoma treatment with vitamin D in an nonhuman animal model. Setting Hospital and university laboratories. Patient(s)/Animal(s) Human leiomyomas were collected from patients and implanted in ovariectomized NOD-SCID mice. Intervention(s) Mice were treated with vitamin D (0.5 μg/kg/d or 1 μg/kg/d) or vehicle for 21 or 60 days. Main Outcome Measure(s) Vitamin D effect in xenograft tissue was assessed by monitoring tumor size (18F-FDG positron-emission tomography/computeriz…

Abstract Study question Is DNA methylation reversion through DNA methyltransferases (DNMT) inhibitors, such as 5-aza–2’-deoxycitidine, a potential therapeutic option for treatment of patients with uterine leiomyomas (UL)? Summary answer 5-aza–2’-deoxycitidine reduces proliferation and extracellular matrix (ECM) formation by inhibition of Wnt/ β-catenin pathway on UL cells, suggesting DNMT inhibitors as an option to treat UL. What is known already: UL is a multifactorial disease with an unclear pathogenesis and inaccurate treatment. Aberrant DNA methylation have been found in UL compared to myometrium (MM) tissue, showing hypermethylation of tumor suppressor genes, which contributes to the d…
Vitamin D as an effective treatment in human uterine leiomyomas independent of mediator complex subunit 12 mutation.
2021
Objective To study whether vitamin D (VitD) inhibits cell proliferation and Wnt/β-catenin and transforming growth factor−β (TGFβ) signaling pathways in uterine leiomyomas independent of mediator complex subunit 12 (MED12) mutation status. Design Prospective study comparing leiomyoma vs. myometrial tissues and human uterine leiomyoma primary (HULP) cells treated with or without VitD and analyzed by MED12 mutation status. Setting Hospital and university laboratories. Patient(s) Women with uterine leiomyoma without any treatment (n = 37). Intervention(s) Uterine leiomyoma and myometrium samples were collected from women undergoing surgery because of symptomatic leiomyoma pathology. Main Outcom…
