Malignant pheochromocytoma is accurately diagnosed only at occurrence of metastatic foci. However, at that time, patients are less likely to get many benefits from traditional chemotherapy. Over-expression of BCL-2 family proteins is tightly correlated with progression of pheochromocytoma. ApoG2, as the most potent gossypol derivative, has exhibited anti-tumor activities in various tumors. In the present study, we found that the staining degree of Bcl-2 being stronger than Bax was more frequently observed in pheochromocytoma than adrenocorticohyperplasia, which was possibly related to shorter overall survival. In addition, ApoG2 could induce apoptosis through up-regulation of Bax and down-regulation of Bcl-2, increasing reactive oxygen species (ROS) levels, inducing cytochrome C release and cleaving caspase proteins. Most importantly, those inhibition effects were blocked by caspase activation inhibitor Z-VAD-fmk and antioxidant N-acetyl-L-cysteine. The above results were further confirmed in vivo. Furthermore, ApoG2 could effectively inhibit tumor movement capabilities. Altogether, our results indicated that ApoG2 was a potential effective target drug for pheochromocytoma.
