Oregano extract induces lung cancer cell deathOriganum syriacum Induces Apoptosis in Lung Cancer Cells by Altering the Ratio of Bax/Bcl2.
We investigated how the methanol extract of Origanum syriacum, commonly known as oregano, affects lung cancer cells, particularly A549 cells. Our study aimed to understand whether this natural extract could suppress cell growth and induce programmed cell death, or apoptosis, which is crucial in targeting cancer cells.
We first checked the cell viability of A549 cells after exposure to various concentrations of oregano extract. Our observations revealed that higher concentrations led to a notable decline in cell growth and prompted significant changes in cell structure. At the 200 mg/ml dose, many cell membranes appeared to break down, indicating a strong response to the treatment.
Moreover, at a lower dose of 25 μg/ml, we noted an increase in Bax expression—a protein that promotes apoptosis—as well as a rise in late apoptotic cells. We also identified key phenolic compounds like vanillic acid and luteolin in the extract, which may contribute to its beneficial effects.
Overall, the evidence suggests that oregano extract can effectively block lung cancer cell growth and induce apoptosis, showcasing its potential as a natural therapeutic agent.
