Abstract
The present study aimed to explore the effects of antifibrotic agent halofuginone on uterine leiomyomas (ULs) cells. The survival of the uterine smooth muscle (UtSMC) cells and UL ELT3 cells were measured. Flow cytometry was used to assess the cell cycle distribution and apoptosis. Effects of halofuginone on the state of AKT/mTOR pathway were evaluated. Xenograft animal model was applied to explore the effects of halofuginone in vivo. Halofuginone inhibited the proliferation of ELT3 cells dose-dependently without obvious influence on UtSMC cells. Halofuginone suppressed cell cycle progression and promoted apoptosis of ELT3 cells dose-dependently. Also, p-AKT/AKT and p-p70S6/p70S6 were significantly lowered after treatment with 20 nM halofuginone. Additionally, halofuginone reduced ELT3 tumor growth in xenograft tumor animal model. The present study illustrates that halofuginone inhibits cell proliferation of ULs with low side effects on normal smooth muscle cells, and AKT/mTOR signaling pathway was inactivated meanwhile.
期刊介绍：
Growth Factors is an international and interdisciplinary vehicle publishing new knowledge and findings on the regulators of cell proliferation, differentiation and survival. The Journal will publish research papers, short communications and reviews on current developments in cell biology, biochemistry, physiology or pharmacology of growth factors, cytokines or hormones which improve our understanding of biology or medicine. Among the various fields of study topics of particular interest include: •Stem cell biology •Growth factor physiology •Structure-activity relationships •Drug development studies •Clinical applications
