Figure 5From: Hederagenin from the leaves of ivy (Hedera helix L.) induces apoptosis in human LoVo colon cells through the mitochondrial pathway Effects of hederagenin on mRNA levels of Bcl-2, Bcl-xL, Bax and Survivin. The mRNA expressions were measured by quantitative RT-PCR and calculated as % of DMOS-only control. β-actin was used as an internal control. *P < 0.05, vs. control (n = 3).Back to article page
