Background:
Traditional Chinese medicines are widely used in cancer treatment. Scutellaria barbata and Hedyotis diffusa herb pair (SH) has an anticancer effects in various tumors. However, the specific mechanism of SH in breast cancer remains unclear.
Methods:
In the present research, we investigated the effect and regulatory network of SH in in breast cancer. CCK8, colony formation, transwell, wound healing and flow cytometry analysis were used for the detection of cell function.
Results:
Ethyl acetate fraction from SH at an equal weight ratio (EA11) could inhibit the proliferation, migration and invasion of MCF7 and MDA-MB-231 cells. It also induced apoptosis in these two cell lines by downregulating Bcl2 and upregulating Bax and Cleaved-Caspase3. SH reduced the activation of the AKT/mTOR signaling pathway and the expression of p70S6K. Sequencing results showed that LMO1 was significantly downregulated in SH-treated cells compared with control cells. Importantly, overexpression of LMO1 attenuated the inhibitory effect of SH on cell proliferation and invasion and induced inflammatory tumor microenvironment.
Conclusion:
In conclusion, the SH herb pair inhibited the proliferation and metastasis through downregulating LMO1 expression and reducing the activation of the AKT/mTOR signaling pathway. LMO1 has the potential as a new target in the treatment of breast cancer.
