Betanin alleviates inflammation and ameliorates apoptosis on human oral squamous cancer cells SCC131 and SCC4 through the NF-κB/PI3K/Akt signaling pathway.

Abstract

Oral squamous cell carcinoma (OSCC) is the prime kind of human malignancy with a great mortality ratio and a deprived prognosis due to its high level of relapse and metastasis. Recently reported is that betanin exerts a preventive role and cytotoxic activity on numerous cancer cells. Betanin comprises the betalain group, which is a highly bioavailable antioxidant. However, the precise molecular actions of betanin in the OSCC cells are yet to be elucidated. It may be the first report on the antiproliferative and apoptotic molecular mechanisms of betanin on OSCC. The current study intended to explore the betanin activity and its underlying mechanisms on SCC131 and SCC4 cells. The cytotoxicity assay, intracellular ROS, MMP, cell apoptosis, and inflammatory mediators of betanin activity on SCC131 and SCC4 cells were evaluated by MTT assay, DCFH-DA, Rh-123, AO/EB, DAPI, PI, analysis of western blot and RT-PCR. The upshots indicated that betanin restrains the SCC131 cells proliferation, MMP and inflammation, whereas induces apoptosis via the enhanced ROS level of SCC131 and SCC4 cells in a dose-dependent mode. Also, betanin-treated OSCC cells reduce inflammatory and apoptotic signaling pathways. The above-mentioned results exposed that betanin can inhibit cell viability, MMP, inflammation and enhanced apoptosis via the expression of NF-κB/PI3K/Akt pathways. Thus, our current findings provided an innovative vision into the protective effect against OSCC.
