Among different tissue homogenate groups, the treatment with Carvacrol through injection (###P ≤ 0.001 vs. tumor and NS vs. normal) showed the strongest effect in lowering Bcl-2 protein levels (Fig. 4B) when compared to both oral and combined treatments (##P ≤ 0.01 vs. tumor and * P ≤ 0.05 vs. normal). This evidence concerns the gene BCL2 and neoplasm.
