The only structural difference between them is that RIZ2 lacks the N-terminal PR domain. In this study we showed that RIZ1 mRNA expression level was elevated in stage IV of eight different types of cancer stage III for prostate cancer indicating that RIZ1 might play an important role in tumor metastasis and the PR domain alone possessed anticancer activity. Key words RIZ1 RIZ Human tumor suppressor tumor metastasis Introduction Yin-Yang regulation which refers to dual complimentary opposite reactions has been discovered in many biological and physiological regulations. Recently human tumor suppressor gene RIZ was shown to function in a Yin-Yang fashion 1 2 . RIZ located on the distal short arm of chromosome 1 1p36 encodes two different protein products RIZ1 and RIZ2 using .
