Background : The young stem of Cinnamomum cassia (YSC) as traditional Chinese medicines has been reported to show a variety of pharmacological properties such as anti-allergy, insecticidal, antimicrobial, antiulcer, anti-inflammatory, immune-suppressive, and neuronal death prevention, tyrosinase inhibition and anticancer, antioxidant and free radical scavenging, as well as antidiabetic and aldose reductase inhibition activities. In this study, we elucidated apoptotic effect and potential molecular mechanism of hot water extracts from YSC (YSC-HW) against human colorectal cancer cells. Methods and Results : YSC-HW treatment increased ROS level and induced ROS-dependent DNA damage in human colorectal cancer cells. ROS generation mediated by YSC-HW induced DNA induced apoptosis and reduction of cell viability in human colorectal cancer cells. YSC-HW ROS-dependently induced NF-kB activation through p65 nuclear translocation via IkB-α degradation, which exerted the induction of apoptosis. In addition, YSC-HW activated ATF3 expression dependent on ROS, which resulted in apoptosis. Conclusion : Our results suggest that YSC-HW may induce apoptosis through ROS-activation of NF-kB and ATF3 in human colorectal cancer cells. From these findings, YSC-HW has potential to be a candidate for the development of chemoprevention or therapeutic agents for human colorectal cancer.
