Abstract: In tumor therapy, looking for a drug that hastheselectively effect on tumor cellsis people expected. As a tumor suppressor the prostate apoptosis response protein-4 (Par-4) can selectively induce apoptosis of the tumor cells and play a role in both cytoplasm and nucleus. However, it be found that par-4 can be secreted and interact with the GRP78 onthe cell surface, causing the endoplasmic reticulum stress, which activates the FADD/caspase-8/caspase-3 pathway leading to apoptosis. Par-4 interacts with other proteins and anticancer drugs during the exercise of its function, and they can co-induce tumor cells apoptosis, which provides new methods and ideas for tumor therapy. This paper reviews the regulatory mechanisms of Par-4 on the selective induction of tumor cell apoptosis and its interaction with relevant genes and other antitumor agents.
