Background
Scutellaria barbata D. Don (SB) is a widely used herbal medicine in China, with various pharmacological effects such as anti-oxidation, anti-inflammation, and anti-cancer. This work is aimed to investigate the tumor-suppressive effect of SB in cervical cancer (CC) and to identify its underlying mechanisms.
Conclusion
SB restrains CC cell proliferation and metastasis and promotes cell apoptosis via miR-195-5p/LOXL2, which may be a potential therapeutic agent for CC treatment.
Results
ECSB repressed the viability, migration, and invasion of HeLa and HT-3 cells, and promoted cell apoptosis in a dose-dependent manner. MiR-195-5p was remarkably under-expressed in CC tissues and cells, and ECSB up-regulated miR-195-5p expression. MiR-195-5p inhibitors partially counteracted the suppressive effects of ECSB on the malignant phenotypes of HeLa and HT-3 cells. LOXL2 was a downstream target of miR-195-5p, and ECSB up-modulated LOXL2 expression by specifically repressing miR-195-5p.
