Anti-angiogenic therapy as potential treatment for adenomyosis

Description

Anti-angiogenic therapy as potential treatment for adenomyosis Abstract Adenomyosis is characterized by abnormal uterine bleeding, dysmenorrhea and subfertility. Increased expression of angiogenesis markers in adenomyosis presents a treatment opportunity and was studied in an adenomyosis mouse model. Mice were administered tamoxifen (1 mg/kg) on neonatal days 2–5. At six weeks of age, mice received oral treatment with axitinib 3 mg/kg (‘dose I/AX3’, n = 34), axitinib 25 mg/kg (‘dose II/AX25’ n = 34), or with vehicle-only (‘placebo’, n = 34). The prevalence and severity of adenomyosis were assessed. An adenomyosis severity index was calculated by multiplying mean grade/mouse by the percentage affected surface area. Angiogenesis-related gene expression was evaluated using real-time quantitative PCR.
