Abstract
Background
Syzygium cumini (L.) Skeels (jambolan) is commonly used in Indian traditional medicine to treat a variety of diseases such as obesity, diabetes etc. The cytotoxic potential of Syzygium cumini (SC) against oral cancer cell line is remains elusive. Therefore, in this study, we evaluated the cytotoxic effect of S. cumini in human oral squamous cell carcinoma (OSCC) cell line (SCC‐25 cells).
Material and Methods
OSCC cells are treated with different concentrations (10, 20 and 40 μg/mL) of S. cumuni for 24 h and cytotoxicity was analyzed by MTT assay. The intracellular reactive oxygen species (ROS) was measured using the indicator dye, 2',7'‐dichlorofluorescin diacetate staining. Apoptosis‐related morphological changes were evaluated by dual acridine orange/ethidium bromide (AO/EB) fluorescent staining and phosphatidylserine externalization was measured by annexin V assays. The protein and gene expression of cadherin‐1 was evaluated by western blotting and PCR analysis.
Results
SC treatments caused cytotoxicity of OSCC cell line and induced intracellular ROS accumulation. This treatment also caused apoptosis related morphological changes and externalization of phosphatidylserine in OSCC cells. Further, SC treatments increased protein and gene expression of cadherin‐1.
Conclusion
S. cumini extract inhibits the proliferation of OSCC cells and induces apoptosis through ROS accumulation and therefore, it could be used for the prevention of OSCC.
