Abstract:
Scutellarin, an active flavone extracted from Erigeron breviscapus, is known to exhibit antitumour activity in many cancers. However, the effects of Scutellarin on osteosarcoma remain unclear. In this study, we found that Scutellarin suppressed osteosarcoma cell growth, induced cell apoptosis and inhibited tumorigenesis. Mechanistically, our data revealed that EGR1 was significantly increased under Scutellarin treatment. Increased EGR1 enhanced tumour-suppressive effects of Scutellarin on osteosarcoma cells via transcriptionally downregulating LINC00857 expression. Additionally, we found that LINC00857 acted as a competitive endogenous RNA of miR-150-5p and inhibited the activity of miR-150-5p, which resulted in c-Myc increase. Scutellarin could suppress c-Myc protein levels through decreasing LINC00857 expression in osteosarcoma. Thus, these findings demonstrate that EGR1/ LINC00857/miR-150-5p/c-Myc axis plays a key role in promoting anticancer effects of Scutellarin and Scutellarin might have potential clinical implication in osteosarcoma clinical treatment.
Insights
Scutellarin, a compound from Erigeron breviscapus, inhibits osteosarcoma growth by boosting EGR1. This pathway downregulates LINC00857, impacting miR-150-5p and c-Myc, offering potential for osteosarcoma treatment.
Area of Science:
- Oncology
- Molecular Biology
- Pharmacology
Background:
- Scutellarin, a flavone from Erigeron breviscapus, shows anticancer properties.
- The specific mechanisms of Scutellarin in osteosarcoma are not well understood.
Purpose of the Study:
- To investigate the effects and underlying molecular mechanisms of Scutellarin on osteosarcoma.
- To explore the potential of Scutellarin as a therapeutic agent for osteosarcoma.
Main Methods:
- Cell growth assays, apoptosis analysis, and tumorigenesis inhibition studies were performed.
- Expression levels of EGR1, LINC00857, miR-150-5p, and c-Myc were analyzed.
- Mechanistic studies explored the regulatory axis involving these molecules.
Main Results:
- Scutellarin suppressed osteosarcoma cell proliferation, induced apoptosis, and inhibited tumor formation.
- Scutellarin treatment upregulated EGR1, which transcriptionally downregulated LINC00857.
- LINC00857 was found to sponge miR-150-5p, leading to increased c-Myc; Scutellarin reduced c-Myc by decreasing LINC00857.
Conclusions:
- The EGR1/LINC00857/miR-150-5p/c-Myc axis is crucial for Scutellarin's anticancer effects in osteosarcoma.
- Scutellarin demonstrates potential for clinical application in treating osteosarcoma.
