Armadillo repeat containing X-linked 3 regulates the proliferation,migration,and invasion of breast cancer cells
To investigate the effect of armadillo repeat containing X-linked 3(ARMCX3) on the proliferation,migration,and invasion of breast cancer cells and its potential molecular mechanism.
Methods
2
Immunohistochemistry was used to measure the expression of ARMCX3 in breast cancer tissue and adjacent tissue,and Western blot was used to measure the expression of ARMCX3 in breast cancer cells. Breast cancer cells were transfected with lentivirus to establish a model of breast cancer cells with low expression of ARMCX3,and flow cytometry,colony formation assay,scratch assay,and Transwell assay were used to observe the effect of ARMCX3 on the proliferation,migration,and invasion of breast cancer cells. TCGA and GTEx databases were used to analyze the expression of SRY-box transcription factor 9(SOX9) in breast cancer tissue,and GEO database was used to analyze the correlation between SOX9 and ARMCX3. Western blot was used to measure the expression levels of E-cadherin,N-cadherin,vimentin,and SOX9 in breast cancer cells.
Results
2
Compared with adja
cent tissue and human normal breast epithelial cells,there was a significant increase in the expression level of ARMCX3 in breast cancer tissue and most breast cancer cell lines(
P
<
0.05). Compared with the control group,the low expression of ARMCX3 inhibited the proliferation,migration,and invasion of MCF-7 and MDA-MB-231 cells,promoted the expression of E-cadherin,and inhibited the expression of N-cadherin and vimentin(
P
<
0.05). Compared with the normal tissue,there was a significant increase in the expression level of SOX9 in breast cancer tissue(
P
<
0.001),which was correlated with ARMCX3,and the low expression of ARMCX3 also significantly inhibited the expression of SOX9.
Conclusion
2
ARMCX3 is highly expressed in breast cancer tissue and breast cancer cells,and it may regulate the proliferation,migration,and invasion of breast cancer cells through SOX9.
