Evaluating Medicinal Plants for Anticancer Activity

Figure 5

Changes in the expression levels of cellular apoptotic proteins following treatment with whole plant extracts. (a)–(d) Colo205 tumor cells were treated with the three plant extracts (1.5 mg/mL each; final concentration) then analyzed for mRNA levels by PCR for Bax protein (a), Bik protein (b), Bcl2 protein (c), and caspase 3 protein (d). The results are expressed as the fold elevation in mRNA levels compared to control cells (treated with DMSO/PBS at the same final concentration as the plant extracts).
