Sinomenine Inhibits Vasculogenic Mimicry and Migration of Breast Cancer Side Population Cells via Regulating miR-340-5p/SIAH2 Axis

Figure 2

Sinomenine downregulates SIAH2 to inhibit epithelial-mesenchymal transition of breast cancer SP cells. Breast cancer SP cells transfected with pcDNA3.1-SIAH2 or pcDNA3.1 were incubated with 0.75 mM of sinomenine under normoxic or hypoxia for 24 h. (a) The protein levels of Snail, N-cadherin, E-cadherin, SIAH2, and HIF-1α were observed by western blot. (b)The relative protein expression levels are shown in the bar graph. (c) The mRNA level of SIAH2 was tested by RT-PCR. Data are represented as the deviation from 3 independent experiments. compared to the control group. compared to the hypoxia group. compared to the e group.
