Effects of Huayu Xiaozheng Granules (化瘀消癥颗粒) on Proliferation, Adhesion and Autophagy of Trophoblast Cells under Hypoxia
To explore the possible mechanism of Huayu Xiaozheng Granules (化瘀消癥颗粒, HXG) in treatment of tubal pregnancy.
Methods
2
The human gestational trophoblast cell line HTR-8/SVneo cells were counted after digestion and seeded in 96-well plates, with three duplicate wells in each group of blank group, hypoxia group, HXG low, medium and high dose groups.The hypoxia model was established 24 hours after giving 0.1 ml CoCl
2
(400 μmol/L) into each duplicate well in the hypoxia group, HXG low, medium and high dose groups
。
After modeling, the mother liquor of HXG (20 mg/ml)at the dose of 50 μl, 100 μl,and 150 μl were added into the culture medium of the HXG low, medium and high dose groups correspondingly, and were observed for 24 h, 48 h and 72 h, based on which the intervention time of the subsequent experiments was determined through CCK8 method.The scratch assay was used to observe the cell migration of each group, and the cell migration rate was calculated. The expression of cellular hypoxia-inducible factor 1α (HIF-1α), epithelial cell cadherin (E-cadherin), neural cadherin (N-cadherin), the iconic protein of autophagy (Beclin-1) and microtubule-associated protein light chain 3 protein Ⅱ (LC3-Ⅱ) were detected through Western blotting.
Results
2
HXG may act on tubal pregnancy by inhibiting the proliferation, adhesion and autophagy activity under hypoxia, and higher dose is associated with better effect.
