ABSTRACT
BACKGROUND:
Research on the role of lncRNAs in the process of bone metastasis in breast cancer (BM-BCa) has just begun at an early stage, and an increasing number of lncRNAs have been proved to play a regulatory role in the process of BM-BCa. Our study focused on the balance of osteogenic-osteoclast regulated by lncRNA-SNHG3 in bone metastasis microenvironment.METHODS:
SNHG3 level of clinical tissues and breast cancer cell lines was determined by RT-qPCR. ALP staining, ALP activity identification and western blotting of OPG, OSX, RUNX2, BMP2 together with BMP3 was performed to verify the osteogenesis of bone marrow mesenchymal stem cells (BMSCs) both in vitro and in vivo. Exosomes derived from MDA-MB-231 were characterized and sequenced, followed by RT-qPCR. Dual luciferase reporter gene assay was utilized to analyze the binding sites of miR-1273g-3p on SNHG3 and BMP3.RESULTS:
Expression of BMP3 was positively regulated by SNHG3 via exosomal miR-1273g-3p.CONCLUSION:
The overexpression of SNHG3 in breast cancer cells may be responsible for osteolytic metastasis Thus, knockdown of SNHG3 might be a potential target for improvement of BM-BCa Treatment.
