Biochem/physiol Actions

Oridonin has potent anti-tumor activity. Oridonin targets AE (AML1-ETO) oncoprotein. Exposure to oridonin induces apoptosis in AE-bearing leukemic cells through the activation of intrinsic apoptotic pathway and triggering a caspase-3-mediated degradation of AE at D188. The compound also prolonged the lifespan of C57 mice bearing truncated AE-expressing leukemic cells without side effects like suppression of bone marrow or reduction of body weight of animals, and exerted synergic effects while combined with cytosine arabinoside. Additionally, oridonin inhibited tumor growth in nude mice inoculated with t(8;21)-harboring Kasumi-1 cells.

The aim of this study was to elucidate the molecular mechanisms mediating hepatocyte growth factor (HGF)-induced protection against oridonin-induced apoptosis in A549 cells. Oridonin induced decrease in Bcl-2/Bax ratio and activation of caspase-3, while these processes were reversed by HGF...

We reported previously that phagocytosis of apoptotic cells by U937 cells was enhanced by the treatment with oridonin that showed high activity to induce the generation of reactive oxygen species (ROS) in many cells. ROS, important signaling molecules, are involved...
