Background: Cervical cancer is one of the leading severe malignancies throughout the world. Sophra flavescens alkaloid (SFA) gels, a compound Traditional Chinese Medicine, has been clinically used in China for many years. Its individual active ingredients are matrine and oxymatrine, which has been showed that they can restrain primary tumorigenesis, while the underlying molecular mechanisms of SFA gels in cervical cancer cells remain unclear.
Methods: To detect the effect of SFA gels and its active ingredients, CCK-8 assay and colony assay were used on cervical cancer cells proliferation. Transwell assay was used to detect cancer cell migration. Apoptosis and cell cycle arrest were used to detect whether SFA gels effect the cervical cancer cells proliferation. Western blot was used to detect whether SFA gels regulate the cervical cancer cells via the suppression of AKT/mTOR signaling pathway.
Results: SFA gels can restrain cervical cancer cell proliferation, inhibit metastasis, induce cell cycle arrest in G2/M phase, induce cellular apoptosis through stimulation of Bax and E-cadherin, and suppression of Bcl-2, cyclin A, MMP2. Further study shows that SFA gels may regulate the cervical cancer cells via the suppression of AKT/mTOR signaling pathway.
Conclusions: SFA gels, like its active ingredients, can restrain cervical cancer cells proliferation, suppress cervical cancer cell migration, induce the apoptosis and cell cycle arrest in cervical cancer cells. SFA gels may be a potential anti-tumor therapeutic agent for treating cervical cancer.
