Figure 4From: Triptolide induces apoptotic cell death of human cholangiocarcinoma cells through inhibition of myeloid cell leukemia-1 Triptolide inhibited Mcl-1 mRNA expression in HuCCT1 and QBC939 cells. (A-B) Triptolide (25–100 nM) significantly reduced Mcl-1 mRNA expression (as assessed by real-time PCR) in both HuCCT1 (A) and QBC939 (B) cells. Expression of Mcl-1 was normalized against the housekeeping gene β-actin. ***p < 0.001, compared with control.Back to article page
