HPTTG1 is an oncogene that overexpressed in most human carcinomas. It was reported to be involved in cell cycle regulation and sister chromatid separation.  PTTG expression level has been associated with tumor progression, invasion, and metastasis. In this study, HPTTG1 expression was analyzed in three cancer patients' groups including; breast cancer, colorectal cancer, and hepatocellular carcinoma patients using RT-PCR. Our data revealed that the expression of PTTG1 was high in three groups; however, the metastatic cases reported higher expression levels of PTTG1 compared to non-metastatic groups. Thus, PTTG1 could be a prognostic marker in different types of cancer patients, and targeting PTTG1 might be a good strategy against metastasis.
